A pilot study of the SNOT 22 score in adults with no sinonasal disease

Predictive factors for decreased baseline quality of life in patients with sinonasal malignancies

BACKGROUND

The impact of sinonasal malignancies (SNMs) on quality of life (QOL) at presentation is poorly understood. The Sinonasal Outcome Test (SNOT-22) and University of Washington Quality of Life (UWQOL) are validated QOL instruments with distinctive subdomains. This study aims to identify factors impacting pretreatment QOL in SNM patients to personalize multidisciplinary management and counseling.

METHODS

Patients with previously untreated SNMs were prospectively enrolled (2015-2022) in a multicenter observational study. Baseline pretreatment QOL instruments (SNOT-22, UWQOL) were obtained along with demographics, comorbidities, histopathology/staging, tumor involvement, and symptoms. Multivariable regression models identified factors associated with reduced baseline QOL.

RESULTS

Among 204 patients, presenting baseline QOL was significantly reduced. Multivariable regression showed worse total SNOT-22 QOL in patients with skull base erosion (p = 0.02). SNOT-rhinologic QOL was worse in women (p = 0.009), patients with epistaxis (p = 0.036), and industrial exposure (p = 0.005). SNOT extranasal QOL was worse in patients with industrial exposure (p = 0.016); worse SNOT ear/facial QOL if perineural invasion (PNI) (p = 0.027). Squamous cell carcinoma pathology (p = 0.037), palate involvement (p = 0.012), and pain (p = 0.017) were associated with worse SNOT sleep QOL scores. SNOT psychological subdomain scores were significantly worse in patients with palate lesions (p = 0.022), skull base erosion (p = 0.025), and T1 staging (p = 0.023). Low QOL was more likely in the presence of PNI on UW health (p = 0.019) and orbital erosion on UW overall (p = 0.03). UW social QOL was worse if palatal involvement (p = 0.023) or PNI (p = 0.005).

CONCLUSIONS

Our findings demonstrate a negative impact on baseline QOL in patients with SNMs and suggest sex-specific and symptom-related lower QOL scores, with minimal histopathology association. Anatomical tumor involvement may be more reflective of QOL than T-staging, as orbital and skull base erosion, PNI, and palate lesions are significantly associated with reduced baseline QOL.

Sino-nasal Outcome Test (SNOT22) score in adult population with no known sino-nasal disease

PURPOSE

This cross-sectional study aimed to establish normative values for Sino-Nasal Outcome Test (SNOT-22) score in adult Indian population without known sino-nasal diseases. The purpose was to fill a critical knowledge gap, providing insights into how various host factors influence SNOT-22 scores which seek to serve as reference for clinical studies, facilitating comparisons of symptom severity and aid in patient counselling based on specific score patterns.

METHODS

One thousand and twelve adults meeting inclusion criteria participated in the study. Participants provided demographic information, occupation details, addiction history, and medical background. They completed SNOT-22 questionnaire, grading their symptoms on Likert scale of 0-5 based on severity experienced in the past 2 weeks. The collected data were analysed to derive meaningful insights.

RESULTS

Mean SNOT-22 score for the study population was 6.80, with 90% scoring below 15, and 40% within 0-3 range. Females exhibited significantly lower mean scores than males. Residents of rural areas reported higher scores than urban counterparts. Education levels had no significant influence on scores. Occupational exposure to aeroallergens, addiction (especially tobacco), and a history of allergies, bronchial asthma, or atopy were associated with significantly higher SNOT-22 scores. Principal component analysis identified four distinct domains, with the nasal symptom domain consistently emerging as the major contributor to differences in subgroups with significantly different total SNOT-22 scores.

CONCLUSION

The normative data and subgroup analyses established in this study serve as a foundation for future research, aiding clinicians in predicting symptoms and providing tailored counselling for individuals with sino-nasal pathologies.

Effectiveness of septoplasty compared to medical management in adults with obstruction associated with a deviated nasal septum: the NAIROS RCT

Background

The indications for septoplasty are practice-based, rather than evidence-based. In addition, internationally accepted guidelines for the management of nasal obstruction associated with nasal septal deviation are lacking.

Objective

The objective was to determine the clinical effectiveness and cost-effectiveness of septoplasty, with or without turbinate reduction, compared with medical management, in the management of nasal obstruction associated with a deviated nasal septum.

Design

This was a multicentre randomised controlled trial comparing septoplasty, with or without turbinate reduction, with defined medical management; it incorporated a mixed-methods process evaluation and an economic evaluation.

Setting

The trial was set in 17 NHS secondary care hospitals in the UK.

Participants

A total of 378 eligible participants aged > 18 years were recruited.

Interventions

Participants were randomised on a 1: 1 basis and stratified by baseline severity and gender to either (1) septoplasty, with or without turbinate surgery (n = 188) or (2) medical management with intranasal steroid spray and saline spray (n = 190).

Main outcome measures

The primary outcome was the Sino-nasal Outcome Test-22 items score at 6 months (patient-reported outcome). The secondary outcomes were as follows: patient-reported outcomes - Nasal Obstruction Symptom Evaluation score at 6 and 12 months, Sino-nasal Outcome Test-22 items subscales at 12 months, Double Ordinal Airway Subjective Scale at 6 and 12 months, the Short Form questionnaire-36 items and costs; objective measurements - peak nasal inspiratory flow and rhinospirometry. The number of adverse events experienced was also recorded. A within-trial economic evaluation from an NHS and Personal Social Services perspective estimated the incremental cost per (1) improvement (of ≥ 9 points) in Sino-nasal Outcome Test-22 items score, (2) adverse event avoided and (3) quality-adjusted life-year gained at 12 months. An economic model estimated the incremental cost per quality-adjusted life-year gained at 24 and 36 months. A mixed-methods process evaluation was undertaken to understand/address recruitment issues and examine the acceptability of trial processes and treatment arms.

Results

At the 6-month time point, 307 participants provided primary outcome data (septoplasty, n = 152; medical management, n = 155). An intention-to-treat analysis revealed a greater and more sustained improvement in the primary outcome measure in the surgical arm. The 6-month mean Sino-nasal Outcome Test-22 items scores were -20.0 points lower (better) for participants randomised to septoplasty than for those randomised to medical management [the score for the septoplasty arm was 19.9 and the score for the medical management arm was 39.5 (95% confidence interval -23.6 to -16.4; p < 0.0001)]. This was confirmed by sensitivity analyses and through the analysis of secondary outcomes. Outcomes were statistically significantly related to baseline severity, but not to gender or turbinate reduction. In the surgical and medical management arms, 132 and 95 adverse events occurred, respectively; 14 serious adverse events occurred in the surgical arm and nine in the medical management arm. On average, septoplasty was more costly and more effective in improving Sino-nasal Outcome Test-22 items scores and quality-adjusted life-years than medical management, but incurred a larger number of adverse events. Septoplasty had a 15% probability of being considered cost-effective at 12 months at a £20,000 willingness-to-pay threshold for an additional quality-adjusted life-year. This probability increased to 99% and 100% at 24 and 36 months, respectively.

Limitations

COVID-19 had an impact on participant-facing data collection from March 2020.

Conclusions

Septoplasty, with or without turbinate reduction, is more effective than medical management with a nasal steroid and saline spray. Baseline severity predicts the degree of improvement in symptoms. Septoplasty has a low probability of cost-effectiveness at 12 months, but may be considered cost-effective at 24 months. Future work should focus on developing a septoplasty patient decision aid.

Post-traumatic olfactory dysfunction: a scoping review of assessment and rehabilitation approaches

Post-traumatic Olfactory Dysfunction (PTOD) consists of a complete or partial loss of olfactory function that may occur after a traumatic brain injury (TBI). PTOD may be linked to some neuropsychiatric features, such as social, cognitive and executive dysfunction, as well as behavioral symptoms, especially when TBI involves the orbito-frontal cortex. The diagnosis of PTOD is based on medical history and clinical data and it is supported by psychometric tests (i.e., subjective tools) as well as electrophysiological and neuroimaging measures (i.e., objective methods). The assessment methods allow monitoring the changes in olfactory function over time and help to establish the right therapeutic and rehabilitative approach. In this context, the use of the olfactory training (OT), which is a non-pharmacological and non-invasive treatment option, could promote olfactory function through top-down (central) and bottom-up (peripheral) processes. To better manage patients with TBI, PTOD should be detected early and properly treated using the various therapeutic rehabilitative possibilities, both conventional and advanced, also taking into consideration the emerging neuromodulation approach.

Evaluation of inverted papilloma recurrence rates and factors associated recurrence after endoscopic surgical resection: a retrospective review

BACKGROUND

Sinonasal inverted papillomas (IP) are benign tumours arising from the mucosal lining of the nasal cavity and paranasal sinuses with a high propensity for recurrence and malignant transformation. Advances in endoscopic surgery and improved radiologic navigation have increased the role of endoscopic surgical resection in the treatment of IPs. The current study aims to evaluate the rate of IP recurrence after endoscopic endonasal resection and to evaluate factors which impact recurrence.

METHODS

This was a single-centre retrospective chart review of all patients who underwent endoscopic sinus surgery for management of IP between January 2009 and February 2022. Primary outcomes were the rate of IP recurrence and time to IP recurrence. Secondary outcome measures were patient and tumour factors that contributed to IP recurrence.

RESULTS

Eighty-five patients were included. The mean age was 55.7 and 36.5% of patients were female. The mean follow-up time was 39.5 months. Of the 85 cases, 13 cases (15.3%) had recurrence of their IP and the median time to recurrence was 22.0 months. All recurrent tumours recurred at the attachment site of the primary tumour. The univariate analysis did not identify any significant demographic, clinical, or surgical predictors of IP recurrence. There were no significant changes in sinonasal symptoms at the time IP recurrence was detected.

CONCLUSION

Endoscopic endonasal resection of IPs represents an effective surgical approach, however, the relatively high rate of recurrence and lack of symptomatic changes at the time of recurrence necessitates long term follow up. Better delineation of risk factors for recurrence can help identify high-risk patients and inform postoperative follow up strategies.

Elexacaftor-Tezacaftor- Ivacaftor improves sinonasal outcomes in cystic fibrosis

BACKGROUND

Many individuals with cystic fibrosis (CF) have chronic rhinosinusitis resulting in nasal obstruction, sinus infections, and repeated surgeries. Elexacaftor-tezacaftor-ivacaftor is a highly effective modulator therapy approved for individuals aged 6 years or older with CF who have at least one F508del allele or other responsive mutation. The current study tests the hypothesis that ELX/TEZ/IVA improves sinonasal disease in CF.

METHODS

The study was a pre/post, observational cohort study conducted at two sites. Participants underwent a study visit prior to starting ELX/TEZ/IVA and a second visit at a median of 9 months on therapy. Each visit included sinus CT scan, rigid nasal endoscopy, and sweat chloride measurement. Symptoms were measured with the 22 item Sinonasal Outcome Test at scheduled intervals during the study. Regression models were used to test for improvement in symptoms, endoscopy, and CT scales.

RESULTS

The study enrolled 34 individuals, with a median age of 27 years (range 12-60). Symptoms improved within 7 days of therapy and plateaued by day 28. Endoscopic crusting resolved and nasal polyposis improved, with a decrease in size or resolution of polyps. Sinus opacification and mucosal thickening improved on CT radiographs with treatment.

CONCLUSIONS

Sinonasal symptoms improved rapidly and durably for at least 180 days on ELX/TEZ/IVA therapy. Objective measures of disease including endoscopic and CT findings improved with ELX/TEZ/IVA.

Pharmacokinetic Evidence of Steady and Sustained Drug Release from Long-Acting Implantable Corticosteroid Matrices for Chronic Rhinosinusitis

Background

The efficacy of topical corticosteroids is limited in chronic rhinosinusitis (CRS) due to rapid clearance from the nasal cavity and insufficient drug delivery to inflamed sinonasal passages. LYR-210 is an implantable corticosteroid matrix designed to provide up to 24 weeks of treatment to patients with CRS by locally delivering mometasone furoate (MF) to the sinonasal mucosa. In a randomized, controlled, dose-ranging LANTERN study, LYR-210 (7500 µg) achieved clinically relevant improvement in CRS cardinal symptom composite scores, the 22-item Sinonasal Outcome Test (SNOT-22), ethmoid opacification, and the need for rescue treatment at 24 weeks.

Objective

As the plasma MF concentrations of LYR-210 (2500 µg) and LYR-210 (7500 µg) were evaluated at weeks 4, 12, and 24 in the LANTERN study (data on file at Lyra Therapeutics, Inc.), this study aims to characterize the pharmacokinetic profiles of both doses of LYR-210 at earlier timepoints post-placement in patients with CRS.

Methods

Twenty-four surgically naïve adult patients with CRS were enrolled in an open-label, multicenter study and underwent in-office bilateral administration of LYR-210 (2500 µg) (n = 12 patients) or LYR-210 (7500 µg) (n = 12 patients) into the middle meatus. Plasma MF concentrations were determined pre-placement and 1-h post-placement (day 1), and on days 2, 3, 7, 14, 21, 28, 42, and 56 by liquid chromatography-tandem mass spectrometry.

Results

Both LYR-210 doses were well-tolerated with no serious adverse events. Systemic MF levels were dose-dependent and lower than reported values of other respiratory MF products. Plasma MF concentrations showed steady drug release from LYR-210 (2500 µg) and LYR-210 (7500 µg) that persisted through day 56.

Conclusion

LYR-210 achieved dose-dependent, continuous local MF delivery at a steady rate with low systemic exposure for months.

The effect of odontogenic sinusitis with periapical lesions on quality of life

<b> Introduction:</b> Usually the symptoms presented in odontogenic sinusitis do not differ from chronic sinusitis of other origin. However, odontogenic sinusitis is considered as an independent disease which requires specific diagnostic approach and treatment. </br></br> <b>Aim:</b> The aim of the study is to define the main symptoms of odontogenic rhinosinusitis with periapical lesions and its impact on the quality of life. </br></br> <b>Material and methods:</b> The SNOT-22 and OHIP-14 questionnaires were distributed among 26 symptomatic patients suffering from odontogenic sinusitis with periapical lesions in the teeth that remain in close contact with the maxillary sinus floor. Data was collected by means of an interview and standard examination performed by an otolaryngologist and a maxillofacial surgeon. The symptoms were also objectified using nasal endoscopy and radiological studies. The acquired data was statistically analyzed. </br></br> <b>Results:</b> The total OHIP-14 score was 14.7 ± 11.3, whereas the total SNOT-22 score was 44.6 ± 18.8. Women scored significantly higher in the total SNOT-22 score as well as domains concerning nasal symptoms, quality of sleep, and emotional symptoms. The answers given in similar items were comparable between both questionnaires. </br></br> <b>Conclusions:</b> Properly diagnosed odontogenic sinusitis (OS) with periapical lesions (PAL) will improve the quality of health-care and spare the patients inadequate procedures. Standard examination should include a unified and validated question-naire concerning both sinonasal and oral symptoms. Painful aching in the mouth and discomfort during eating might help to identify the OS with PAL during a medical interview and help both ENT (ear-nose-throat) specialists and dentists to establish proper patient-oriented diagnosis and treatment.

Rhinosinusitis without nasal polyps is associated with poorer health-related quality of life in COPD

Rhinosinusitis without nasal polyps (RSsNP) is prevalent in COPD. Previous studies on its association with health-related quality of life (HRQoL) have limitations, and RSsNP is currently not recognized as a comorbidity. This study investigates HRQoL in COPD including a focus on RSsNP. Generic HRQoL was assessed with the Short Form-36 (SF-36v2) questionnaire and compared between 90 COPD and 93 control subjects and in subgroups with and without RSsNP. The association between RSsNP and COPD versus not and generic HRQoL was assessed by multivariable linear regression with adjustments for age, education, and body mass index (BMI). Disease-specific HRQoL was assessed by Sinonasal outcome test-22 (SNOT-22), St. Georges Respiratory Questionnaire (SGRQ), and COPD Assessment Test (CAT) and compared between COPD with and without RSsNP, and their association to RSsNP was assessed by multivariable linear regression with adjustments for age, BMI, and FEV₁% predicted. RSsNP was associated with poorer disease-specific HRQoL, with higher SNOT-22 total score (14.67 points; 95% CI, 7.06-22.28; P < .001) and psychological subscale score (3.24 points; 95% CI, 0.37-6.11; P = .03), SGRQ symptom score (13.08 points; 95% CI, 2.73-23.4; P = .014), and CAT score (4.41 points; 95% CI, 1.15-7.66; P = .009). Generic HRQoL was poorer in COPD patients than in the control subjects. In addition to COPD, concomitant RSsNP was associated with poorer physical functioning, general health, vitality, and physical component summary. RSsNP in COPD is associated with poorer disease-specific HRQoL that is clinically relevant and, as it is amenable for treatment, should be recognized as a comorbidity of COPD.

Upper airway symptoms associate with the eosinophilic phenotype of COPD

BACKGROUND

There is growing evidence that upper airway symptoms coexist with lower airway symptoms in COPD. Still, the prevalence and impact of upper airway disease on the nature and course of COPD remain unclear. We aimed to describe this in a cross-sectional study.

METHODS

We examined a cohort of COPD patients with pulmonary function tests, induced sputum, blood eosinophils, atopy tests and computed tomography (CT) of the paranasal sinuses. Lower airway symptoms were assessed using the COPD Assessment Test (CAT), and upper airway symptoms were assessed using the nasal subdomain of the 22-item Sino Nasal Outcome Test (SNOT22nasal). We recruited patients from five sites in Denmark and Sweden. We excluded patients with a history of asthma.

FINDINGS

In total, 180 patients (female 55%, age 67±8 years, forced expiratory volume in 1 s (FEV1 %) 52.4±16.6, Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage: A: 18%, B: 54%, C: 3%, D: 25%) were included in the study. Seventy-four patients (41%) reported high upper airway symptoms (UAS, defined as SNOT22nasal≥6) with a median score of 10 (IQR 8-13). Patients with high UAS reported higher CAT scores (17.4±7.5 versus 14.9±6.6, p<0.05) and displayed higher fractions of eosinophils in blood (median 3.0% (IQR 1.6-4.2%) versus 2.3% (IQR 1.4-3.1%), p<0.05) and in induced sputum (median 1.8% (IQR 0.3-7.1%) versus median 0.5% (IQR 0-1.7%), p<0.05). No differences in atopy, CT findings or exacerbation rates were observed.

CONCLUSION

COPD patients with upper airway disease showed increased evidence of eosinophilic disease and increased lower airway symptom burden.

Balloon sinuplasty: two-year follow up using Sino-Nasal Outcome Test-22 outcomes

BACKGROUND

Balloon sinuplasty is a relatively new surgical technology proposed as a less invasive way of treating chronic rhinosinusitis and frontal sinus disease. It is crucial to monitor safety and efficacy to allow informed clinical decisions and appropriate counselling of patients. There are few papers with long-term follow up.

METHOD

Patients were selected for surgery based on symptoms of frontal pain and pressure or headache, pre-operative Sino-Nasal Outcome Test-22 scores, and computed tomography findings. All were resistant to appropriate medical therapy. Balloon sinuplasty was performed followed by a Sino-Nasal Outcome Test-22 questionnaire at two months and then two years.

RESULTS

All patients underwent successful operations with no failure of technology or technique. There were no significant complications. The average Sino-Nasal Outcome Test-22 score reduced from 46 pre-operatively (standard error: +/- 5.7, n = 9) to 23 at 2 months (standard error: +/- 7.6, n = 7). At 2 years, the average Sino-Nasal Outcome Test score was 23 (standard error: +/- 4.3, n = 6). There was an even larger lasting benefit when pain or pressure symptoms were analysed in isolation.

CONCLUSION

This study adds to the evidence of technique safety and feasibility. The procedure resulted in a significant long-term improvement in symptoms.

How face masks influence the sinonasal quality of life during the COVID-19 pandemic

Purpose

To study different mask types’ impact on a sinonasal quality of life.

Methods

For this observational cross-sectional study, a web-based survey was distributed via social media forums. We used the validated Hebrew version of the Sinonasal Outcome Test–22 followed by a questionnaire developed specifically for the present study, focusing on the time of the COVID-19 pandemic (Mask Sinonasal Outcome Test), and questions regarding general health issues. The participants’ mask-wearing routine was also studied.

Results

Seventy percent of 351 participants had experienced a change in their breathing during the time of the pandemic. The median total Sinonasal Outcome Test–22 score was 13, and 10% of the participants reported a significantly impaired quality of life. According to multivariate analyses, the only subject-related variables significantly associated with the reduced sinonasal quality of life were female gender, younger age, a background of chronic rhinitis and sinusitis, and the mask-wearing average daily duration. The mask sinonasal outcome test convergent validity was confirmed.

Conclusion

The majority of our survey’s responders, predominantly female and younger participants, reported reduced sinonasal quality of life in the COVID-19 pandemic period. It can be attributed to mask-wearing, especially for a prolonged time, irrespective of the existing mask type. These findings should encourage medical companies to produce more “airway-minded” personal protection equipment.

Impact of renal replacement therapies on olfactory ability: results of a cross-sectional case control study

Introduction

Several studies have suggested that chronic kidney disease (CKD) may be associated with olfactory impairment. However, to date, the impact of renal replacement therapies has only been partly defined.

Methods

We tested the olfactory function of 235 participants [50 kidney transplant recipients (KT), 49 hemodialyzed patients (HD), 30 peritoneal dialysis patients (PD), 51 patients with CKD not on dialysis (ND-CKD) and 55 healthy subjects (HS)] by the Sniffin’ Sticks test (Burghardt®, Wedel, Germany), including the sub-tests for the determination of odor threshold (T), odor discrimination (D), odor identification (I). Each subtest result was then summed up to a composite score, known as the TDI score. The Sino-Nasal Outcome Test-22 (SNOT22), Montreal Cognitive Assessment (MoCA) test and olfactory function Visual Analogue Scale (ofVAS) were also performed.

Results

The mean TDI score was significantly lower (and consistent with hyposmia), in HD, PD and ND-CKD compared to HS and KT (ANOVA p < 0.001). Similar results were observed in the I and D tests, and with the T score, though with regard to the latter, only in PD and ND-CKD patients. Multiple comparisons among groups demonstrated no significant differences between KT and HS. After adjustments for confounding factors, a significant linear association was found between both urea (β − 0.03, p < 0.003) and eGFR (β 0.08, p < 0.001) with TDI score. No significant association was observed between the TDI score and the ofVAS score (p = 0.293).

Conclusions

Olfactory impairment affects a large number of CKD patients in the pre-dialysis phase as well as those on dialysis. Kidney transplantation may reverse this condition with a possible positive impact on the quality of life and social behaviors/relationships.

Chronic rhinosinusitis in COPD: A prevalent but unrecognized comorbidity impacting health related quality of life

INTRODUCTION

Unified airway disease where upper respiratory tract inflammation including chronic rhinosinusitis (CRS) affects lower airway disease is known from asthma, bronchiectasis, cystic fibrosis and primary ciliary dyskinesia but little is known about CRS and health related quality of life in COPD. We investigate firstly, the prevalence of CRS in COPD. Secondly the impact of CRS on HRQoL. Thirdly, risk factors for CRS in COPD.

METHODS

cross-sectional study of CRS in 222 COPD patients from 2017 to 2019 according to EPOS2012/2020 and GOLD2019 criteria. Patients completed the COPD assessment test (CAT), Medical Research Council dyspnea scale and Sinonasal outcome test 22 (SNOT22) and questions on CRS symptoms. They then had a physical examination including flexible nasal endoscopy, CT-sinus scan and HRCT-thorax.

RESULTS

22.5% of COPD patients had CRS and 82% of these were undiagnosed prior to the study. HRQoL (CAT, SNOT22 and the SNOT22-nasal symptom subscore) was significantly worse in COPD patients with CRS compared with those without CRS and healthy controls. Multiple logistic regression analysis suggests that the most likely candidate for having CRS was a male COPD patient who actively smoked, took inhaled steroids, had a high CAT and SNOT22_nasal symptom subscore.

DISCUSSION

the largest clinical study of CRS in COPD and the only study diagnosing CRS according to EPOS and GOLD. This study supports unified airway disease in COPD. The SNOT22_nasal symptoms subscore is recommended as a standard questionnaire for COPD patients and patients at risk should be referred to an otorhinolaryngologist.

The effect of surgical menopause after bilateral oophorectomy on hormonal changes, mucociliary clearance, and quality of life

PURPOSE

The removal of the ovaries for any reason causes surgical menopause. Hormonal changes that occur progressively over 5-10 years in natural menopause occur acutely in surgical menopause. Signs of estrogen deficiency appear suddenly and are permanent after this surgery. This study investigated the short- and long-term effects of estrogen deficiency occurring after surgical menopause on both nasal mucociliary activity and sinonasal symptoms.

METHODS

This prospective study included women aged 20-45 years who were not in the menopause, who had a planned bilateral oophorectomy and who attended the Gynecology Clinic at the Faculty of Medicine at a university hospital between January 2018 and December 2019. The nasal mucociliary clearance time, and blood Estradiol (E2) and FSH levels were measured once in the preoperative period, and at the postoperative 3rd, 6th, 9^th, and 12th months. At the same times, the Sinonasal Outcome Test 22 (SNOT-22) was also applied.

RESULTS

 The average age of the 47 patients was 41.2 ± 2.7. The mean serum estradiol levels of the women were 164.7 ± 63.4 pg/ml in the preoperative period, 14.8 ± 3.7 pg/ml at the postoperative 3rd month, 12.5 ± 3.5 pg/ml at the postoperative 6th month, 11.6 ± 3.0 pg/ml at the postoperative 9th month, and 11.1 ± 2.7 pg/ml at the postoperative 12th month. The mean FSH levels of the women were 9.4 ± 2.4 mIU/ml in the preoperative period, 60.5 ± 9.6 mIU/ml at the postoperative 3rd month, 61.9 ± 9.4 mIU/ml at the postoperative 6th month, 63.0 ± 9.3 mIU/ml at the postoperative 9th month, and 64.6 ± 8.7 mIU/ml at the postoperative 12th month. The changes in postoperative mean estradiol and FSH levels over a year were significant and consistent with menopausal symptoms (p < 0.001). The mean mucociliary clearance times were 12.6 ± 1.2 before menopause, 13.2 ± 1.7 at the postoperative 3rd month, 14.5 ± 1.7 at the postoperative 6th month, 17.5 ± 1.6 at the postoperative 9th month, and 19.4 ± 1.9 at the postoperative 12th month. The extension of the mean mucociliary clearance time over 1 year was significant (p < 0.001). The mean scores for the SNOT-22 were 17.3 ± 6.9 before the operation, 17.8 ± 6.0 at the postoperative 3rd month, 19.6 ± 6.9 at the postoperative 6th month, 23.4 ± 10.4 at the postoperative 9th month, and 36.1 ± 10.0 at the postoperative 12th month. The mean scores for rhinologic symptoms were 5.2 ± 1.9 (3-11) in the preoperative period, 5.7 ± 2.0 (3-12) at the postoperative 3rd month, 7.1 ± 2.3 (4-14) at the postoperative 6th month, 9.3 ± 3.3 (4-16) at the postoperative 9th month, and 11.9 ± 3.3 (6-18) at the postoperative 12th month. The 1-year change in the SNOT-22 scores was found to be significant (p < 0.001).

CONCLUSION

After bilateral oophorectomy, menopausal hormonal values were acutely high in women. At the 1-year postmenopausal follow-up, the mean scores for the SNOT-22 had increased significantly. In other words, quality of life decreased in parallel with prolonged nasal mucociliary clearance time.

Development, reliability, validity and sensitivity of the Sino-Nasal Outcome Test for Neurosurgery (SNOT-NC)

BACKGROUND

The transnasal endoscopic approach to lesions of the skull base has come into routine practice in recent years. Standardized questionnaires to assess the postoperative sequelae are missing. The authors present a custom-made questionnaire for the sino-nasal outcome test for neurosurgery (SNOT-NC) in accordance with the SNOT-22.

METHODS

The SNOT-NC was developed with respect to the German version of the Sino-Nasal Outcome Test (SNOT-22) which is used for patients suffering from rhinosinusitis. It consists of 23 items covering "Nasal Discomfort", Sleep Problems/Reduced Productivity", "Ear and Head Discomfort", "Visual Impairment" and "olfactory impairment". The SNOT-NC was specifically adapted to patients undergoing transnasal operations of skull base lesions. The Short Form 36 health survey (SF-36), a nasal ad hoc questionnaire and the "Sniffin' Sticks" test were used for analyzing convergent and divergent validity. The psychometric and clinimetric analyses were performed using the data of 102 consecutive patients treated by transnasal operations for skull base lesions.

RESULTS

Factorial validity was secured by a confirmatory factor analysis. The internal consistency (Cronbach's Alpha) for the subscales ranged from .62 to .85, while it was .84 for the whole instrument. The Guttman's lower reliability limits range estimates corresponded closely to the Cronbach's Alpha coefficients obtained. Examination of convergent and divergent validity revealed substantial associations between the SNOT-NC and a wide range of related nasal symptoms (p < .05). Different aspects of sensitivity were analyzed statistically with Cohen's t statistic for change (pairwise t tests) exhibiting at least p < .05) underlining the sensitivity of the SNOT-NC.

CONCLUSIONS

The SNOT-NC appears to be a valid, reliable and sensitive measure for assessing the clinical outcome of patients undergoing transnasal endoscopic skull base surgery. The SNOT-NC proved to be a valuable tool to assess the nasal discomfort outcome of patients at follow-up examinations. Further analyses encompassing analyses for retest reliability are called for the future.

Add-on probiotics in patients with persistent allergic rhinitis: A randomized crossover clinical trial

OBJECTIVES

Current medications for allergic rhinitis (AR) may have undesirable side effects that could affect quality of life (QoL). Probiotics could be an alternative in these patients. The aim of this study was to assess the impact of add-on probiotics on symptoms and QoL of patients.

METHODS

In this randomized crossover clinical trial, patients with persistent AR were included. Each subject received budesonide with probiotic supplements (BP) or budesonide with placebo for 8 weeks (B), then vice versa for a further 8 weeks. There was an 8-week washout. The primary outcome was the change of the Short Form 36-Item Health Survey (SF-36) score. The secondary outcomes were assessed by the Sinonasal Outcome Test-22 (SNOT-22) and the Control of Allergic Rhinitis and Asthma Test (CARAT) questionnaires.

RESULTS

A total of 152 subjects (30.1 ± 7.6 years) completed the study. The SF-36 score in both groups showed improvement compared with baseline values. Treatment BP was more effective than that of B. The Cohen's d and the number needed to treat for Physical Component Scales of SF-36 were 0.40 and 10.77, respectively. These values for Mental Component Scales were 0.33 and 12.61, respectively. Also, treatment BP showed more reduction in the score of SNOT-22 and CARAT.

CONCLUSION

This study showed that the addition of probiotics to budesonide significantly improved QoL in persistent AR patients. However, the clinical situation of these patients may be not very representative of AR patients in general population. Further studies are recommended.

NAVIGATE I: Randomized, Placebo-Controlled, Double-Blind Trial of the Exhalation Delivery System With Fluticasone for Chronic Rhinosinusitis With Nasal Polyps

BACKGROUND

Chronic rhinosinusitis is a common, high-morbidity chronic inflammatory disease, and patients often experience suboptimal outcomes with current medical treatment. The exhalation delivery system with fluticasone (EDS-FLU) may improve care by increasing superior/posterior intranasal corticosteroid deposition.

OBJECTIVE

To evaluate the efficacy and safety of EDS-FLU versus EDS-placebo in patients with nasal polyps (NP). Coprimary end points were change in nasal congestion and polyp grade. Key secondary end points were Sino-Nasal Outcome Test-22 (SNOT-22) and Medical Outcomes Study Sleep Scale-Revised (MOS Sleep-R). Other prespecified end points included all 4 cardinal symptoms of NP, 36-Item Short Form Health Survey (SF-36), Patient Global Impression of Change (PGIC), Rhinosinusitis Disability Index (RSDI), and key indicators for surgical intervention.

DESIGN

Randomized, double-blind, EDS-placebo-controlled, multicenter study.

METHODS

Three hundred twenty-three subjects with NP and moderate-severe congestion/obstruction, most with history of corticosteroid use (94.4%) and/or prior surgery (60.4%), were randomized to EDS-FLU 93 µg, 186 µg, or 372 µg or EDS-placebo twice daily (BID) for 24 weeks (16 double-blind + 8 single-arm extension with EDS-FLU 372 µg BID).

RESULTS

All EDS-FLU doses produced significant improvement in both coprimary end points ( P < .05) and in SNOT-22 total score ( P ≤ .005). EDS-FLU significantly improved all 4 cardinal symptoms of NP ( P < .05), including congestion/obstruction, facial pain/pressure, rhinorrhea/post-nasal drip, and hyposmia/anosmia. Approximately 80% of subjects reported improvement with EDS-FLU, with 65% reporting "much" or "very much" improvement by week 16. Adverse events were generally local in nature and similar to other intranasal steroids studied for similar durations in similar populations, with the most common being epistaxis.

CONCLUSIONS

In patients with chronic rhinosinusitis with NP (CRSwNP) who were symptomatic despite high rates of prior intranasal steroid use and/or surgery, EDS-FLU produced statistically significant and clinically meaningful improvements compared to EDS-placebo in multiple subjective and objective outcomes (symptoms, SNOT-22, RSDI, SF-36, PGIC, and NP grade), including all 4 cardinal symptoms of CRSwNP.

Acellular Human Dermal Allograft as a Graft for Nasal Septal Perforation Reconstruction

BACKGROUND

Nasal septal perforations pose a troubling source of morbidity for patients and a difficult problem for the otolaryngologist. Multiple surgical techniques have been tried, with inconsistent success. Prosthetic nasal buttons also have limitations, including patient intolerance and dissatisfaction. Acellular human dermal allograft (AlloDerm) has been described as an alternative material for septal perforation repair. The authors studied objective and subjective outcomes, including quantification of the patient's symptoms in septal perforation repair with AlloDerm.

METHODS

The authors performed a prospective cohort study of 12 patients with 1- to 2-cm anterior septal perforations who were recruited from a tertiary care practice. Patients with admitted smoking or cocaine use in the previous 3 months or vascular or granulomatous diseases were excluded. Subjective scores on the Sino-nasal Outcome Test-22, along with objective nasal endoscopy and acoustic rhinometry measures, were collected at baseline and 2, 4, and 12 weeks postoperatively. Patients were followed for reperforation 9 to 20 months postoperatively. Data were normalized to baseline values and analyzed using analysis of variance and Bonferroni correction.

RESULTS

Successful closure of the septal perforation was obtained in 10 of 12 patients and confirmed with rigid nasal endoscopy. Nasal symptom scores (Sino-nasal Outcome Test-22 ) were significantly reduced to 52.8 percent (95 percent CI, 35.1 to 70.5 percent; p < 0.01) of baseline symptoms at 4 weeks postoperatively. At 12 weeks postoperatively, symptoms were measured at 26.6 percent (95 percent CI, 10.9 to 42.1 percent; p < 0.01) of baseline symptoms. Acoustic rhinometry confirmed perforation closure, demonstrating a reduction in cross-sectional nasal area from baseline of 55.1 percent (95 percent CI, 37.7 to 66.8 percent; p < 0.01).

CONCLUSION

This is the first study to use objective and subjective measurements to confirm success with acellular dermis allograft as an adjunct for septal perforation repair, demonstrating a statistically significant reduction in patient nasal symptoms following repair.

Olfactory Training in Post-Traumatic Smell Impairment: Mild Improvement in Threshold Performances: Results from a Randomized Controlled Trial

Traumatic Brain Injury (TBI) can be associated with partial or total smell loss. Recent studies have suggested that olfactory outcome can be positively modulated after olfactory training (OT). This study's aim was to investigate OT's potential role in smell recovery after TBI-induced olfactory loss. A prospective, randomized, and controlled study was developed. Patients with TBI-induced olfactory dysfunction (n = 42) were randomized into an experimental group with OT and a control group without (nOT). OT was performed twice daily with a six odor training set during 12 weeks. Olfactory loss was assessed using subjective olfactometry (Barcelona Smell Test [BAST] 24), a visual analogue scale (VAS), and n-butanol threshold (n-BTt) at baseline at 4, 12, and 24 weeks. Additionally, patients underwent MRI of the olfactory brain and olfactory bulbs (OB). Based on the MRI results, an overall score (0-16) was developed to associate the structural neurological damage with olfactory outcomes. The primary outcome was the change in olfactory measurements (VAS and BAST-24) between baseline and 12 weeks. The secondary outcome was the association of the MRI score with olfactory outcomes at baseline, and the impact on quality of life (QoL). After 12 weeks of training, OT patients showed a significant improvement in n-BTt (0.6 ± 1.7 OT vs. -0.6 ± 1.8 nOT, p < 0.05), but not in the smell VAS and BAST-24 scores. Olfactory outcomes (VAS, BAST-24, and n-BTt) were significantly associated with MRI structural findings (p < 0.001), but not with the OB volume or olfactory sulcus length. The present study suggests that 12 weeks of OT mildly improves the olfactory threshold in TBI, whereas the overall MRI score may be used as an imaging marker of olfactory dysfunction and disease severity in TBI patients.

The burden of chronic rhinosinusitis and its effect on quality of life among patients re-attending an otolaryngology clinic in south western Uganda

BACKGROUND

Worldwide, the burden of chronic rhinosinusitis (CRS) is variable, but not known in Uganda. CRS has significant negative impact on quality of life (QOL) and as such QOL scores should guide adjustments in treatment strategies. However, most of these studies have been done in the west. Our hypothesis was that QOL scores of the majority of CRS patients in low- to- middle income countries are poorer than those among patients without CRS. The aim of this study was to determine the burden of CRS among patients re-attending the Otolaryngology clinic and whether CRS is related to poor QOL.

METHODS

A cross sectional study was conducted at Mbarara Regional Referral Hospital Otolaryngology clinic. One hundred and twenty-six adult re-attendees were consecutively recruited. Data was collected using a structured questionnaire and the Sinonasal Outcome Test 22 (SNOT 22) questionnaire measured QOL.

RESULTS

The proportion of re-attendees with CRS was 39.0% (95% CI 30-48%). Majority of CRS patients had poor quality of life scores compared to non-CRS (88% versus 20% p < 01). The poor quality of life scores on the SNOT 22 were almost solely as a result of the functional, physical and psychological aspects unique to CRS.

CONCLUSIONS

CRS is highly prevalent among re-attendees of an Otolaryngology clinic at a hospital in resource limited settings and has a significant negative impact on the QOL of these patients.

NAVIGATE II: Randomized, double-blind trial of the exhalation delivery system with fluticasone for nasal polyposis

BACKGROUND

Chronic rhinosinusitis is common and sometimes complicated by nasal polyps (NPs). Corticosteroid nasal sprays are often unsatisfactory because they are ineffective at delivering medication to high/deep sites of inflammation.

OBJECTIVE

We sought to assess whether an exhalation delivery system with fluticasone (EDS-FLU) capable of high/deep drug deposition improves outcomes.

METHODS

Patients (n = 323) 18 years and older with moderate-to-severe congestion and NPs were randomized to twice-daily EDS-FLU (93, 186, or 372 μg) or exhalation delivery system (EDS)-placebo for 24 weeks (16 double-blind plus 8 open-label when all received 372 μg). Coprimary end points were change in nasal congestion/obstruction at 4 weeks and summed bilateral polyp grade at 16 weeks. Secondary end points included symptoms, polyp elimination, and functioning.

RESULTS

EDS-FLU was superior on both coprimary end points (P < .001 vs EDS-placebo, all doses). Mean polyp grade improved continuously through week 24 (P < .009, all comparisons), with polyps eliminated on at least 1 side in approximately 25% of patients at week 24 versus 8.7% with EDS-placebo (P ≤ .014, all comparisons). Sino-Nasal Outcomes Test scores also improved significantly versus those in patients receiving EDS-placebo (-21.1 to -21.4 vs -11.7 at week 16, P < .05 all doses). At the end of the double-blind period, EDS-FLU (all doses) significantly improved all 4 defining disease symptoms. In most patients (68%), those receiving EDS-FLU reported "much" or "very much" improvement. The number of patients eligible for surgery decreased by 62%-67%. The safety profile was similar to that reported in prior trials evaluating conventional corticosteroid nasal sprays in comparable populations.

CONCLUSION

EDS-FLU produces clinically and statistically significant improvement in all 4 diagnostically defining disease symptoms, polyp grade, and quality of life in patients with chronic rhinosinusitis with NPs.

EXHANCE-12: 1-year study of the exhalation delivery system with fluticasone (EDS-FLU) in chronic rhinosinusitis

BACKGROUND

Inadequate efficacy of current intranasal steroids in chronic rhinosinusitis (CRS) is attributable to ineffective and/or inconsistent drug delivery to target anatomic sites. A new exhalation delivery system with fluticasone (EDS-FLU) may improve outcomes by significantly increasing superior/posterior corticosteroid delivery. A study was conducted to assess the long-term efficacy and safety outcomes of EDS-FLU in individuals with CRS.

METHODS

This was a 12-month, multicenter, single-arm study evaluating the safety and efficacy of EDS-FLU 372 μg twice daily in CRS patients (with [n = 34] or without [n = 189] nasal polyps [NP]). Efficacy assessments by serial nasal endoscopy and patient report included: 22-item Sino-Nasal Outcome Test (SNOT-22), NP grade, standardized surgical indicator assessment, Lund-Kennedy score, and Patient Global Impression of Change. Adverse event (AE) evaluations included nasal endoscopy. Additional safety and efficacy outcomes were assessed.

RESULTS

Of 223 patients who received EDS-FLU, 96% reported prior corticosteroid use and 29% prior sinus surgery. The EDS-FLU AE profile was similar to conventional intranasal steroids studied in similar populations. Most patients (87%) reported symptom improvement. Through 12 months, mean SNOT-22 scores improved by -21.5 and -21.1 for CRS with and without NP, respectively. Among patients with NP, 54.2% had polyp elimination in at least 1 nostril and 83.3% had ≥1-point improvement in polyp grade.

CONCLUSION

Over 1 year of treatment in CRS with and without NP, EDS-FLU 372 μg twice daily was well tolerated and produced improvements across a broad range of objective and subjective measures. EDS-FLU may be a desirable new option for patients with this condition.

Otolaryngic manifestations of Cushing disease

Cushing disease is a relatively rare cause of Cushing syndrome secondary to a hyperfunctioning pituitary adenoma. In addition to signs and symptoms of hypercortisolism, Cushing disease may present with diverse otolaryngic manifestations, which may guide diagnosis and management. We performed a retrospective chart review of patients who were found to have Cushing disease and who underwent transnasal transsphenoidal surgery for pituitary adenomas between January 1, 2007, and July 1, 2014, at a tertiary academic medical center. There were 37 consecutive patients in this series with Cushing disease caused by a pituitary adenoma. Fifteen (41%) patients complained of visual changes. Five (14%) patients suffered from obstructive sleep apnea. Four (11%) patients had thyroid disease. Other symptoms included hearing loss, vertigo, tinnitus, epistaxis, dysphagia, and salivary gland swelling. Although Cushing disease traditionally presents with classic "Cushingoid" systemic features, it also may present with various otolaryngic manifestations. A thorough workup by otolaryngologists is critical in the comprehensive management of these patients.

Use of the long-term quality of life assessment in the decision to indicate surgery in patients with chronic rhinosinusitis

Introduction

Quality-of-life questionnaires have been used to support decision-making in patients with chronic rhinosinusitis in the past decade. The choice of treatment in practice, however, also considers the patient's decision.

Objective

To assess the long-term quality of life of patients with chronic rhinosinusitis who decided to avoid surgery.

Methods

This is a prospective longitudinal study with a group of patients with chronic rhinosinusitis, with and without indication for surgery, with application of the questionnaire SNOT-22 in two periods: between 2011 and 2012 and between June and August 2016, via email.

Results

Data were collected from 42 patients, of which 13 presented indications for surgery and 29 were not indicated for surgery. The average quality of life score was 42.1 (±16.4) in the group with an indication for surgery and 40.6 (±23.4) in the group without this indication, p = 0.84. All the patients were assessed by a single doctor with blinding in relation to the initial score. No differences were detected between the groups. The impact of the chronic rhinosinusitis was reduced even among the patients with the indication for surgery. Both groups scored over 40.

Conclusion

This study can help predict the impact of the chronic rhinosinusitis over time and better adjust expectations with non-surgical treatment.

Are validated patient-reported outcomes used on children in pediatric otolaryngology? A systematic review

OBJECTIVES

Review the pediatric otolaryngology literature to 1) identify studies in which children completed patient-reported outcome (PRO) measures and 2) appraise the psychometric quality and validity of these PROs as they apply to pediatrics.

METHODS

In October 2016, a systematic review was performed by two reviewers on PubMed/MEDLINE and EMBASE for all otolaryngology-related studies that utilized PROs in children. Inclusion criteria included articles that required children (age<18) to complete PROs. Exclusion criteria included validation studies, reviews, and abstracts. Interreviewer agreement was determined using Cohen's kappa. Quality and rigor of validation testing for included PROs was determined using the COnsensus-based Standards for selection of health status Measurement Instruments.

RESULTS

Interrater agreement was very good (κ = 0.91; 95% CI, 0.85-0.98). Out of 316 articles retrieved, 11 met inclusion criteria. Eight PROs were identified. Six PROs were tested for validity and three of these PROs were tested for validity specifically within children. The most frequently utilized PRO was the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire. Two studies (18.2%) utilized PROs within the scope of their validation. Seven studies (63.6%) used PROs outside the scope of their validation. Two studies (18.2%) used non-validated PROs.

CONCLUSIONS

Patient-reported outcomes have become an integral part of research and quality improvement. There is a relative paucity of PROs directed towards children in pediatric otolaryngology and some studies utilized PROs that were not validated or not validated for use in this age group. Future efforts to design and validate more instruments may be warranted.

General illness and psychological factors in patients with chronic nasal symptoms

OBJECTIVES

Only a minority of patients referred to specialists with sinonasal symptoms have clear evidence of chronic rhinosinusitis (CRS). This study aims to estimate the prevalence of and associations between (i) general illness factors (fatigue, autonomic dysfunction) and (ii) psychological factors (anxiety, depression, somatisation, personality traits) in patients presenting with sinonasal symptoms.

DESIGN

The following validated questionnaires were administered to patients: the Sino-Nasal Outcome Test-22 (SNOT-22) identifying symptom burden, Composite Autonomic Symptom Score-31 (COMPASS-31) measuring autonomic function, Chalder Fatigue Questionnaire, Patient Health Questionnaire-15 (PHQ-15) addressing somatisation symptoms, Hospital Anxiety and Depression Scale (HADS), and the International Personality Item Pool-50 (IPIP-50). Comparisons were made with normative and general population data, and relationships were analysed using nonparametric correlation.

SETTING

Secondary care ENT outpatients.

PARTICIPANTS

Adults referred with chronic sinonasal symptoms.

MAIN OUTCOME MEASURES

SNOT-22, COMPASS-31, Chalder, PHQ-15, HADS, and IPIP-50 questionnaire scores.

RESULTS

Sixty-one patients were included. There was a high prevalence of all general and psychological factors assessed compared with controls. Total SNOT-22 scores showed significant correlation with Chalder fatigue scores, total autonomic dysfunction score, anxiety, depression, somatisation tendencies and the emotionally unstable personality trait. Emotional instability and psychological dysfunction correlated significantly with sleep and psychological subscales of SNOT-22 but not the rhinological or ear/facial subscales.

CONCLUSION

Patients with sinonasal symptoms demonstrate high prevalence and complex associations of general illness factors, psychological distress and certain personality traits. The SNOT-22 is a valuable tool, but its utility is limited by correlations with these confounding factors (eg psychological factors) that may exaggerate the total score. The use of the SNOT-22 component subscales is likely to provide more clinically meaningful and discriminant information.

Optimizing Sellar Reconstruction After Pituitary Surgery with Free Mucosal Graft: Results from the First 50 Consecutive Patients

BACKGROUND

Postoperative cerebrospinal fluid leak after endoscopic pituitary surgery ranges from 1.9% to 10% in different series. Vascularized flaps have reduced the incidence of leak; however, this carries nasal morbidity. This study presents a technique for sellar reconstruction with free mucosal graft from the nasal cavity floor including inferior meatus mucosa. This technique aims to standardize sellar reconstruction without the use of the nasoseptal flap and to keep the advantage of mucosal coverage of the defect in all cases.

METHODS

Fifty consecutive patients who had endoscopic surgery for pituitary tumors and reconstruction with nasal cavity floor free mucosal graft were retrospectively reviewed. There were a total of 50 patients with postoperative follow-up from 3 to 16 months. Collagen dural graft was used inlay and free mucosal graft overlay to cover the sellar defect. No fat grafts or lumbar drains were used. A Sinonasal Outcome Test-22 (SNOT-22) was performed before, 1 and 3 months after surgery.

RESULTS

There were 40% detected intraoperative leaks and no postoperative leaks. Nasal endoscopy performed at 1 month follow-up showed complete healing of the graft to the skull base and near total or complete mucosalization of the donor site. No significant difference was found in the SNOT-22 comparing the total preoperative and 1-month scores.

CONCLUSIONS

The nasal cavity floor free mucosal graft is an easy and safe technique, with minimal nasal morbidity. There were no postoperative cerebrospinal fluid leaks, despite aggressive tumor resection. No lumbar drains or fat graft were used. The harvest of mucosal graft does not worsen the quality of life measured with the SNOT-22 test.

Review article: outcomes in endoscopic sinus surgery

Chronic rhinosinusitis has a significant impact on health-related and generic quality-of-life, has a high cost burden to both society and patients, and may be associated with absenteeism, loss of productivity and poor respiratory function. Though there is a paucity of level 1 evidence, endoscopic sinus surgery may be considered in medically refractory patients and a variety of objective and subjective outcome measures exist to assess the effectiveness of intervention. We outline the outcome measurements available and review in-depth the published outcomes to date. Furthermore we discuss the literature that indicates that endoscopic sinus surgery can have a positive effect on respiratory function in asthma. How patient selection, timing and extent of surgery, and post-operative care interventions may optimise surgical outcomes is explored.

Can we use the questionnaire SNOT-22 as a predictor for the indication of surgical treatment in chronic rhinosinusitis?

Introduction

Chronic rhinosinusitis is a prevalent disease that has a negative impact on the lives of sufferers. SNOT-22 is considered the most appropriate questionnaire for assessing the quality of life of these patients and a very effective method of evaluating therapeutic interventions; however it is not used as a tool for decision-making.

Objective

To test the hypothesis that the SNOT-22 score can predict the outcome of surgical treatment.

Methods

A retrospective, longitudinal and analytical study. We evaluated the medical records of patients with chronic rhinosinusitis that completed the SNOT-22 at the time of diagnosis. All the patients were consecutively receiving care at an otolaryngology service in Salvador, Bahia from August 2011 to June 2012. The outcomes of the surgical treatment of these patients were obtained from their medical records. The initial score was compared to a group of patients who were not referred for surgery. All the patients completed and signed a consent form.

Results

Of the 88 patients with chronic rhinosinusitis, 26 had evolved to surgery over the last 3 years. The groups were homogeneous regarding gender and respiratory and medication allergies. The patients of the surgical group were 44.8 + 13.8 years old and the patients of the clinical group were 38.2 + 12.5 years old (p = 0.517). The average SNOT-22 score of the case group was 49 + 19 and the average score of the control group was 49 + 27 (p = 0.927).

Conclusion

The SNOT-22 was unable to predict the outcome of surgical patients with chronic rhinosinusitis.

Low 22-item sinonasal outcome test scores in chronic rhinosinusitis: Why do patients seek treatment?

OBJECTIVES/HYPOTHESIS

Patients with chronic rhinosinusitis (CRS) who experience minimal reductions in quality of life (QoL) may present for treatment despite QoL scores comparable to controls without CRS. This study seeks to identify cofactors influencing patients with CRS and low 22-item Sinonasal Outcome Test (SNOT-22) scores to seek care.

STUDY DESIGN

Prospective, multicenter, observational cohort.

METHODS

Patients with CRS were enrolled between April 2011 and September 2015. Patients with sinonasal mucocele or unilateral sinus opacification were excluded. Control subjects without CRS were enrolled for comparison. Low-SNOT CRS was defined as a SNOT-22 score < 20.

RESULTS

A total of 774 subjects (low-SNOT CRS, n = 38; high-SNOT CRS, SNOT-22 ≥ 20, n = 641; controls without CRS, n = 95) were enrolled. Low SNOT scores were identified in 6% of subjects with CRS. After adjustment, low-SNOT CRS and control groups without CRS reported similar baseline average SNOT-22 total scores (P = .879). Unexpectedly, compared to controls, low-SNOT CRS patients had significantly better average psychological (2.1 ± 2.3 vs. 5.8 ± 6.0; P = .030) and sleep dysfunction (2.7 ± 3.4 vs. 6.0 ± 5.2; P = .016) scores. Fourteen of 38 (37%) low-SNOT patients elected to undergo endoscopic sinus surgery (ESS), with a significantly lower likelihood of reporting a minimal clinically important difference (MCID) when compared to high-SNOT patients (43% vs. 82%; P < .001) after a mean follow-up of ∼15 months.

CONCLUSIONS

Low-SNOT CRS patients represent an outlier population for which measures of QoL fail to identify factors influencing the decision to seek treatment. Low-SNOT CRS patients electing ESS have a decreased likelihood of reporting MCIDs following ESS. Further study is required to identify novel factors associated with treatment-seeking behavior in this population.

Rhinosinusitis associated with post-dental extraction chronic oroantral fistula: outcomes of non-surgical management comprising antibiotics and local decongestion therapy

Objective:

A non-surgical approach for managing rhinosinusitis associated with chronic oroantral fistula resulting from tooth extraction was evaluated.

Methods:

Twenty-six consecutive patients (15 males and 11 females) aged 28–72 years (mean, 49.81 years) were administered local decongestion therapy for 2 weeks and antibiotics for 10 days. Patients showing a reduction in Sino-Nasal Outcome Test 22 scores after two weeks continued to receive local decongestion therapy weekly for up to six weeks, while those not showing any improvement underwent surgical management.

Results:

At 2 weeks, 17 patients (65.38 per cent) showed an improvement in rhinosinusitis (33.39 per cent mean reduction in Sino-Nasal Outcome Test 22 scores). The primary determinant of response was fistula size. At 6 weeks, sinusitis resolved completely in all 17 patients, and the fistula closed in 16 of these. Final Sino-Nasal Outcome Test 22 and Lund–Mackay scores showed no significant difference between the surgically treated and non-surgically treated groups.

Conclusion:

Local decongestion therapy along with antibiotics may promote resolution in this subset of rhinosinusitis patients.

Sino-Nasal Outcome Test-22: Translation, Cross-cultural Adaptation, and Validation in Hebrew-Speaking Patients

OBJECTIVE

To perform the translation, cross-cultural adaptation, and validation of the Sino-Nasal Outcome Test-22 (SNOT-22) questionnaire to the Hebrew language.

STUDY DESIGN AND SETTING

A single-center prospective cross-sectional study.

SUBJECTS AND METHODS

Seventy-three chronic rhinosinusitis (CRS) patients and 73 patients without sinonasal disease filled the Hebrew version of the SNOT-22 questionnaire. Fifty-one CRS patients underwent endoscopic sinus surgery, out of which 28 filled a postoperative questionnaire. Seventy-three healthy volunteers without sinonasal disease also answered the questionnaire. Internal consistency, test-retest reproducibility, validity, and responsiveness of the questionnaire were evaluated.

RESULTS

Questionnaire reliability was excellent, with a high internal consistency (Cronbach's alpha coefficient, 0.91-0.936) and test-retest reproducibility (Spearman's coefficient, 0.962). Mean scores for the preoperative, postoperative, and control groups were 50.44, 29.64, and 13.15, respectively (P < .0001 for CRS vs controls, P < .001 for preoperative vs postoperative), showing validity and responsiveness of the questionnaire.

CONCLUSION

The Hebrew version of SNOT-22 questionnaire is a valid outcome measure for patients with CRS with or without nasal polyps.

Decrease of nasal airway resistance and alleviations of symptoms after balloon sinuplasty in patients with isolated chronic rhinosinusitis: a prospective, randomised clinical study

OBJECTIVES

The aim of this study was to evaluate and compare the clinical outcome of balloon sinuplasty and uncinectomy for patients suffering from isolated chronic rhinosinusitis of the maxillary sinus.

DESIGN

A prospective, randomised, non-blinded, controlled trial was conducted.

SETTING

The study was carried out at the Department of Otolaryngology, Tampere University Hospital, Finland.

PARTICIPANTS

Adult patients with symptomatic isolated chronic or recurrent rhinosinusitis without severe findings in the sinuses, as documented in the sinus' Computer Tomography scan and clinical examination, were randomised into two groups: uncinectomy and balloon sinuplasty.

MAIN OUTCOME MEASURES

The variables in our study are the Sinonasal Outcome Test-22 (SNOT 22), acoustic rhinometry and rhinomanometry. These parameters were analysed preoperatively and postoperatively (after 3 and 6 months).

RESULTS

The preliminary results of our study have been previously published. Both balloon sinuplasty and uncinectomy significantly improved almost all the parameters of SNOT22 (P < 0.05), with no significant difference being found between these two groups (P > 0.05). Based on rhinomanometry results, airway resistance decreased after treatment. Regarding adverse effects, balloon sinuplasty was significantly associated with a lesser risk of synechia.

CONCLUSIONS

Both balloon sinuplasty and uncinectomy improved the quality of life and decreased upper airway resistance of patients with mild, isolated chronic or recurrent rhinosinusitis. The smaller risk of postoperative synechiae with balloon sinuplasty combined with its promising efficiency could partially compensate for its high material cost.

Influence of age and gender in the normal values of Sino Nasal Outcome Test-22

OBJECTIVES

Sino Nasal Outcome Test (SNOT)-22 is a disease-specific outcomes measure questionnaire that combines rhinologic issues with general health issues. These issues may have variable weight on quality of life perception, and the influence of several factors such as gender, ethnicity, age, socio-cultural status and co-morbidities is unknown. The aim of this study was to evaluate the influence of gender and age on normal values of SNOT-22.

DESIGN

Cross-sectional study based on application of SNOT-22 questionnaires to healthy volunteers. Participants were divided according to gender, and each gender was subdivided into age groups: 18-30 years, 31-40 years, 41-50 years, 51-60 years and over 60 years.

SETTING

Rhinology Section, Sao Paulo Federal University.

PARTICIPANTS

A total of 539 healthy volunteers (253 men and 286 women) were selected, so that each age group of each gender consisted of at least 50 individuals.

MAIN OUTCOMES MEASURES

We applied SNOT-22 questionnaire to volunteers with no nasal or sinus disease. Median of score distribution was used as normal reference.

RESULTS

Men presented lower scores than women (7 versus 9, P = 0.005). Subjects over 60 years presented significantly lower scores than other age groups (18-30 years = 10; 31-40 years = 8; 41-50 years = 9; 51-60 years = 9; over 60 years = 7). Men presented lower scores than women especially in 41-50 year and 51-60 year groups.

CONCLUSION

Men and elderly presented the lowest Brazilian version SNOT-22 scores. The range of 0-8 points seemed to be more suitable as a normal value for this instrument, but this cut-off score could be tailored to age and gender specificities.

Acoustic rhinometry and video endoscopic scoring to evaluate postoperative outcomes in endonasal spreader graft surgery with septoplasty and turbinoplasty for nasal valve collapse

BACKGROUND

Nasal obstruction is a common complaint seen by otolaryngologists. The internal nasal valve (INV) is typically the narrowest portion of the nasal cavity, and if this area collapses on inspiration the patient experiences significant symptoms of nasal obstruction. The nasal obstruction is further compounded if the INV is narrower than normal. Previous studies have evaluated the effectiveness of techniques to alleviate structural nasal obstruction, but none have looked specifically at spreader grafts measured by acoustic rhinometry or validated grading assessment of dynamic INV collapse. Our objective was to evaluate the application of acoustic rhinometry coupled with visual endoscopic grading of the INV, and validated subjective measurements, in patients undergoing endonasal spreader graft surgery with septoplasty and turbinoplasty.

METHODS

This is a prospective clinical study conducted within a tertiary care rhinoplasty practice. Patients undergoing septoplasty and bilateral inferior turbinoplasty with bilateral endonasal spreader graft placement for observed internal nasal valve collapse were recruited. Baseline, early and intermediate postoperative measures were obtained. The primary outcome was grading of the INV collapse on video endoscopy. Secondary outcomes included cross-sectional area at the INV measured by acoustic rhinometry, subjective Nasal Obstruction Symptom Evaluation (NOSE) and Sino-Nasal Outcome Tool (SNOT-22) scores.

RESULTS

A total of 17 patients, average age of 34.5 ± 12.2 years, undergoing septoplasty, bilateral endonasal spreader grafts, and bilateral turbinoplasty were included in the study. Postoperative measurements were performed at an average of 8.1 ± 1.6 weeks and 17.7 ± 4.2 weeks. Patients had significant improvement for INV collapse grading, cross-sectional area, NOSE and SNOT-22 scores in both the early and intermediate follow up. Endoscopic grading had moderate inter-rater agreement (κ = 0.579) and average intra-rater agreement (κ = 0.545).

CONCLUSIONS

This study is the first to demonstrate a statistically significant improvement of objective measurement of internal nasal valve function, both static and dynamic, and subjective improvements. This supports endonasal cartilagenous spreader grafts with septoplasty and inferior turbinoplasty for patients with nasal obstruction with internal nasal valve collapse.

Intra-oral low level laser therapy in chronic maxillary sinusitis: A new and effective recommended technique

Background

Chronic sinusitis is one of the most common chronic diseases involving different age groups. Because the nature and etiology of chronic sinusitis are not completely known, there is not any standard treatment for this disease. It has been suggested that low-level laser can be used in treating chronic sinusitis but there are limited studies about its usage. In this research, intra-oral radiation of low-level laser has been described and implemented for the first time. Suggested hypotheses about the efficacy of this type of radiation (intra-oral) in treating chronic maxillary sinusitis includes this fact that the depth of maxilla’s vestibule is also the floor of maxillary sinus and sinus discharges collect in this area because of gravity effect. Therefore, with considering suitable radiation angle, this area gets the most benefits of laser’s anti-inflammatory effects.

Material and Methods

In this study, 20 patients with chronic maxillary sinusitis were included. They were assessed before and after treatment. Treatment plan was performed in 8 sessions every other days using low-level diode laser with 810 nm. Snot-22 questionnaire and rhinomanometry were used for evaluating patients. Changes of signs and symptoms were recorded in questionnaire every session and 6 months after treatment. Friedman and Wilcoxon tests were used for data analyses. In this study, P value < 0.05 was considered statistically significant.

Results

All variables and all symptoms of patients were improved using intra-oral low-level laser and this improvement was statistically significant (P value<0.05). There was also significant decrease in nasal airway resistance and significant increase in air flow (P value<0.05). Six month after treatment completion, there was no significant difference between the results of completion and the results of 8th treatment session (P value< 0.05).

Conclusions

Using intra-oral low-level laser is a suitable way to treat patients with chronic maxillary sinusitis.

Twenty-two-item Sino-Nasal Outcome Test in a control population: a cross-sectional study and systematic review

BACKGROUND

The 22-item Sino-Nasal Outcome Test (SNOT-22) is a commonly utilized outcome measure for chronic rhinosinusitis (CRS). However, what constitutes a normal score remains poorly defined. The goal of this study was to evaluate SNOT-22 scores in a control population without CRS and perform a systematic review and meta-analysis of "normal" values.

METHODS

Ninety-nine subjects without CRS were enrolled, with 95 fully completing the SNOT-22 questionnaire. Multivariable linear regression was used to determine whether demographic factors or medical comorbidities influence SNOT-22 scores in a population without CRS. A systematic literature search was performed, identifying studies that evaluated the SNOT-22 in a non-CRS population and estimates for SNOT-22 values were pooled.

RESULTS

Thirty-six males and 59 females were included in the primary analysis with a mean age of 53.4 ± 17.3 years (range, 18-88 years). The mean SNOT-22 score was 16.4 ± 15.2. Asthma (p = 0.003) and depression (p = 0.002) were found to be independent predictors of higher SNOT-22 scores. Thirteen articles were identified in the literature search and 1 was provided via author correspondence, with 10 reporting sufficient data to be included in the meta-analysis. Weighted mean SNOT-22 score was 11 ± 9.4 (n = 1517). Our data differed significantly from published data (mean difference = 5.4; 95% confidence interval [CI], 3.4 to 7.5; p < 0.0001) likely owing to differences in comorbidities.

CONCLUSION

SNOT-22 scores vary in non-CRS populations depending upon the group queried. Asthma and depression are associated with higher SNOT-22 scores and should be considered when determining what constitutes a normal value.

Impact of postoperative endoscopy upon clinical outcomes after endoscopic sinus surgery

BACKGROUND

After endoscopic sinus surgery (ESS), endoscopy is used to gauge surgical success and clinical outcomes. Prior studies have not examined this topic prospectively using validated outcome metrics across multiple institutions.

METHODS

A multi-institutional, prospective study of patients with chronic rhinosinusitis (CRS) who underwent ESS completed the 22-item Sino-Nasal Outcome Test (SNOT-22), missed productivity, and medication usage questionnaires 6 months postoperatively. Lund-Kennedy endoscopy scoring (LKES) was performed with reviewers blinded to patient-reported data. A control cohort of non-CRS patients was recruited for comparison.

RESULTS

Complete data was available on 183 CRS patients and 48 non-CRS control patients. Approximately 50% of patients achieve perfect or near perfect endoscopy (LKES 0 to 2) after ESS. Postoperative endoscopy correlated with total SNOT-22 scores (r = 0.278, p < 0.001), with the strongest correlations to rhinologic and extranasal subdomains in the nasal polyp cohort. Improved postoperative endoscopy was associated with decreased antibiotic and oral steroid usage, but had little association with missed productivity. Among patients who achieved near perfect postoperative endoscopy, those with nasal polyps had SNOT-22 scores that were similar to non-CRS control patients (mean SNOT-22 scores 17.7 and 16.3, respectively). However, CRS patients without nasal polyps remained more symptomatic than non-CRS controls and CRS with nasal polyps patients despite nearly perfect endoscopy (mean SNOT-22 score 21.6).

CONCLUSION

Postoperative endoscopy correlates with SNOT-22 and medication usage in CRS patients. Polyp patients who achieve near perfect endoscopy have similar symptoms to healthy controls; however, nonpolyp patients with near perfect endoscopy still have rhinologic and extranasal symptoms that are worse than healthy controls.

Should average SNOT 22 scores be calculated regionally?

CONCLUSION

The average SNOT 22 score should be calculated locally and be used as a reference when managing patients with nasal symptoms.

OBJECTIVE

To calculate the average Sino Nasal Outcome Test (SNOT) 22 score across Lanarkshire and to compare it with similar studies.

METHODOLOGY

Prospective data collection in which SNOT 22 forms were filled by the Lanarkshire population who had no history of sinonasal disease. Participants included patient attendants and hospital staff across multiple hospital sites in NHS Lanarkshire. All patients with hay fever, previous nasal surgeries, or any history of use of topical steroid sprays were excluded from the study.

RESULTS

This study included 118 participants, out of which three had to be excluded due to unclear data entry. The total number for SNOT forms included for analysis was 115. This included 85 females and 29 males, while one form remained unanswered. The mean age was 49 (range = 15-81) years. The mean SNOT 22 score was 18 (range = 0-89).

Long-term quality of life after endoscopic removal of sinonasal inverted papillomas: a 6-year cohort analysis in a tertiary academic hospital

Inverted papillomas may affect the (para)nasal cavity. While some of these papillomas can undergo malignant transformation, others grow slowly and cause few if any symptoms. An endoscopic approach is seen as providing a balance between the greatest removal possible and avoiding unnecessary morbidity. However, the actual long-term quality of life of patients having undergone surgery for inverted papillomas has never been studied. Our primary aim is to assess the long-term sequelae and the quality of life of patients after endoscopic surgery of sinonasal inverted papillomas. The secondary aim is to establish which nasal symptoms, if any, are the most prevalent before and after surgery. We used the SNOT-22 questionnaire to assess the quality of life of patients who had undergone endoscopic surgery for sinonasal inverted papillomas between 2000 and 2011. Twenty-seven out of 34 patients returned the questionnaire (79 % response rate). Median follow-up was 6 years (range 1-10). Mean age was 58.9 years (range 40-85). Median SNOT-22 score was 12, while the most frequent postoperative symptom was the need to blow the nose (18 patients) and the most frequent preoperative symptom was nasal obstruction. Patients after endoscopic removal of sinonasal inverted papillomas return to an almost normal quality of life, as measured by the disease-specific questionnaire SNOT-22. The most frequent symptom was the need to blow the nose.
