Abstract
OBJECTIVE We aimed to evaluate computed tomography (CT) images of patients with empty nose syndrome (ENS), investigate the impact of reconstruction surgery on sinus inflammation, and identify the optimal airspace diameter after surgery. METHODS We conducted a retrospective case series analysis, identifying and enrolling patients with ENS with perioperative CT findings. The clinical characteristics of the participants were collected, and the modified Lund-Mackay (mLM) CT scores were determined. The anterior airspace diameter was evaluated by measuring the distance between the septum and the lateral nasal wall on the coronal plane at the level of the nasolacrimal duct. RESULTS Twenty patients with ENS and perioperative CT images were enrolled. The mean total mLM CT score and all subsite scores showed no significant changes after surgery. The Empty Nose Syndrome 6-item Questionnaire (ENS6Q) score, Sino-nasal Outcome Test-25 (SNOT-25) score, sleep symptoms domain, psychological domain, and empty nose symptoms domain were significantly associated with anterior airspace diameter in the regression analysis. CONCLUSION There was no significant difference in sinus inflammation between preoperative and postoperative CT evaluations. The anterior airspace diameters were significantly associated with ENS6Q and SNOT-25 scores. LEVEL OF EVIDENCE 4 Laryngoscope, 134:2105-2110, 2024.

Abstract
OBJECTIVES Empty nose syndrome (ENS) is an underdiagnosed but burdensome clinical condition. Studies that have addressed the impact of remnant inferior turbinate volume (ITV) on ENS are scarce. We aimed to evaluate the impact of ITV and phenotyping on the severity and presentation of ENS. METHODS All the enrolled patients underwent the following subjective assessments: the ENS 6-Item Questionnaire (ENS6Q), Sino-Nasal Outcome Test-25 (SNOT-25), Beck Depression Inventory-II (BDI-II) and Beck Anxiety Inventory (BAI). The ITV was obtained from finely cut (1-mm-thick slices) sino-nasal computed tomography scan images and analyzed using ImageJ. The correlation between ITV, subjective measurements, and morphology of inferior turbinates was evaluated. ENS was categorized as torpedo type (balanced tissue volume) or pistol type (posterior dominance) based on the morphology. RESULTS Overall, 54 patients met the inclusion criteria. The ITV was positively correlated with the ENS6Q score and domain of ENS symptoms in SNOT-25. Neither BDI-II nor BAI scores had a significant correlation with ITV. Based on their morphological classification, the torpedo type exhibited diverse manifestations in the SNOT-25 analysis in response to changes in ITV, while the pistol type demonstrated an elevated rhinologic symptom burden and ENS-specific symptoms as their ITV increased. Nasal resistance did not correlate with the ITV in either type of ENS. CONCLUSIONS Symptoms were paradoxically worse in ENS patients with greater remnant ITV, and distinct morphological phenotypes in the nasal cavities may result in different presentations. Further investigation into the correlation between remnant inferior turbinates and nerve function is warranted. LEVEL OF EVIDENCE 3 Laryngoscope, 2024.

Abstract
Trigeminal-specific stimulants have been shown to activate different receptors preferentially and this likely accounts for variation in sensory perception. It is unclear whether trigeminal sensitivity is similar across different transient receptor potential (TRP) receptors or if dysfunction of different receptors results in differing patient symptoms. Therefore, a prospective cohort study was conducted, consisting of trigeminal lateralization testing with three different stimulants (eucalyptol, isothiocyanate, acetic acid), olfaction testing with Sniffin' Sticks, and measurement of various patient-reported outcome measures (PROMs). A total of 50 participants were enrolled across the olfactory spectrum. Mean TDI score was 27.1 ± 8.3 (range 7.0-39.5) with 38% normosmic and 62% dysosmic. Mean trigeminal lateralization scores out of 20 in the overall cohort were 16.18 (2.78) for eucalyptol, 14.94 (3.49) for mustard oil, and 15.28 (3.68) for vinegar. Eucalyptol showed a significant correlation with threshold scores of Sniffin' Sticks. A significant correlation was found between acetic acid and various PROMs. None of the lateralization scores of the trigeminal stimulants correlated to each other significantly and there was no correlation to age. The lack of correlation suggests that the measured sensitivity of one type of TRP receptor may not translate to similar sensitivity of the other receptors. Additional investigations with TRPV1 and TRPA1 agonists are needed to corroborate our findings.

Abstract
PURPOSE The aim of this prospective study was to examine the characteristics of a clinical test for the assessment of nasal trigeminal sensitivity to mechanical stimuli and its association with the perception of nasal patency. METHODS Thirty-two normosmic healthy subjects participated (17 women and 15 men; age = 26 ± 3 years). Precisely defined air puffs were used with a flow rate of 2L/min for mechanical stimulation. They were presented to the nasal vestibule, nasal septum, and inferior turbinate with various stimulus durations. Thresholds were measured by single-staircase stimuli with changes in stimulus duration in steps of 10 ms. Trigeminal suprathreshold intensity was rated by subjects for stimulus durations of 200, 300, 400, and 500 ms. Test-retest reliability was examined by intraclass correlations (ICCs) and Bland-Altman plot with limits of agreement. Pearson's correlations were calculated between self-rated nasal patency and nasal trigeminal sensitivity. RESULTS As indicated by trigeminal threshold and suprathreshold intensities, the nasal vestibule is the most sensitive area among the three locations, followed by the nasal septum and the inferior turbinate (p < 0.001). Coefficients of correlations between test and retest were 0.76 for thresholds, and 0.56 suprathreshold intensities (p < 0.001). The Bland-Altman analysis showed a good agreement between test-retest values. In addition, significant positive associations between trigeminal suprathreshold intensities and self-rated nasal obstruction were found at the inferior turbinate (r = 0.4, p < 0.05). CONCLUSION Reliable assessment of nasal trigeminal sensitivity for air puffs appears to be possible. Nasal trigeminal suprathreshold sensitivity to mechanical stimuli is associated with the perception of nasal patency at the inferior turbinate. This opens a window into the assessment of the perception of nasal airflow in various clinical purposes, especially for patients with sinonasal diseases. LEVEL OF EVIDENCE: 3

Abstract
OBJECTIVE To investigate novel methods of measuring intranasal trigeminal function and correlate to validated measures of trigeminal function. STUDY DESIGN Prospective cohort study. SETTING Tertiary medical center. METHODS Forty-one subjects without nasal congestion were assessed. The trigeminal temperature function of the cool/warmth detection threshold and cold/heat pain threshold was measured with the Thermal Sensory Analyzer (TSA) device, as previously validated at buccal mucosa and infraorbital skin. Identical temperature sensory function was assessed at the anterior septum and inferior turbinate. Lateralization of trigeminal odorants eucalyptol, isothiocyanate, and acetic acid was conducted. Visual analog scales (VAS) of trigeminal function were collected. RESULTS Extraoral cheek site and oral site thermal measures were moderately correlated, suggesting consistent assessment of trigeminal function. Nearly all intranasal thermal measures correlated between the septum and turbinate (significant correlations [ρ] ranged from .3 to .8). Oral and extraoral cheek sites had modest correlations to intranasal cold and heat pain (ρ = .4-.5). The oral site had modest correlations of cold and heat detection to intranasal sites, with turbinate appearing to have the most correlations. Isothiocyanate lateralization was the most closely correlated to intranasal thermal scores for cold and heat pain. Turbinate thermal measures had weak correlations with trigeminal VAS scores (ρ = .3-.4). CONCLUSION Intranasal trigeminal measures of thermal function correlate to validated extraoral and intraoral thermal measures. The turbinate appears to have stronger correlations to the septum than found in the mouth and face. TSA testing might provide a rapid, novel method of intranasal trigeminal function assessment.

Abstract
Objective Men represent more than two-thirds of septoplasty patients in many studies, but differences between men and women in terms of patient selection or outcome are seldom reported. This study aims to investigate whether women undergoing septoplasty differ from men in critical variables before and after surgery, in a large national sample of septoplasties. Design Cross-sectional register study. Participants The study includes 2,532 patients from the National Swedish Septoplasty Register undergoing septoplasty with or without additional turbinoplasty on the indication of nasal obstruction in 2014-2019. Patients in the register have not been preselected. Main outcome measures Preoperative variables and postoperative outcome were compared between men and women. Results Men accounted for 1,829 (72%) of the patients. There was no significant difference between men and women in severity of self-reported nasal obstruction or type of surgery performed (septoplasty with or without turbinoplasty). Mean postoperative nasal obstruction 12 months after surgery and overall satisfaction with the result were similar. Women, however, reported more complications 12 months postoperatively, while men reported more problems with snoring and obstructive sleep apnea preoperatively. Conclusion In this large national patient cohort undergoing septoplasty, we found no differences in preoperative nasal obstruction or postoperative patient-rated outcome in men and women undergoing septoplasty, despite the fact that 72% of the patients were men. It thus remains unclear why women are under-represented in septoplasty surgery in this and many other cohorts.

Abstract
INTRODUCTION Chronic rhinosinusitis (CRS) affects 5-12% of the general population with significant effects on quality of life. Chronic inflammation also seems to affect intranasal trigeminal sensitivity. AREAS COVERED A systematic literature search was done in Scopus, Web of Science, and PubMed in February 2023. The review addressed intranasal trigeminal function in patients with CRS and summarized current knowledge on trigeminal function as it relates to the symptoms, assessment, and treatment of CRS. EXPERT OPINION Olfaction and trigeminal function are synergistic and this interaction may contribute to trigeminal dysfunction in CRS. Aside from anatomic blockage through polypoid mucosal changes, trigeminal dysfunction may affect the perception of nasal obstruction in CRS. Upregulated immune defense mechanisms leading to damage of nerve endings, changes in nerve growth factor release or other mechanisms may be responsible for trigeminal dysfunction in CRS. Since the pathophysiology of trigeminal dysfunction in CRS is poorly understood, current treatment recommendations are directed toward the therapy of CRS as an underlying cause, although the effect of surgery and corticosteroids on trigeminal function remains unclear. A standardized and validated trigeminal test that is accessible and easy to use in clinical settings would be beneficial for future studies.

Abstract
The sense of smell is important. This became especially clear to patients with infection-related olfactory loss during the SARS-CoV-2 pandemic. We react, for example, to the body odors of other humans. The sense of smell warns us of danger, and it allows us to perceive flavors when eating and drinking. In essence, this means quality of life. Therefore, anosmia must be taken seriously. Although olfactory receptor neurons are characterized by regenerative capacity, anosmia is relatively common with about 5 % of anosmic people in the general population. Olfactory disorders are classified according to their causes (e. g., infections of the upper respiratory tract, traumatic brain injury, chronic rhinosinusitis, age) with the resulting different therapeutic options and prognoses. Thorough history taking is therefore important. A wide variety of tools are available for diagnosis, ranging from short screening tests and detailed multidimensional test procedures to electrophysiological and imaging methods. Thus, quantitative olfactory disorders are easily assessable and traceable. For qualitative olfactory disorders such as parosmia, however, no objectifying diagnostic procedures are currently available. Therapeutic options for olfactory disorders are limited. Nevertheless, there are effective options consisting of olfactory training as well as various additive drug therapies. The consultation and the competent discussion with the patients are of major importance.

Abstract
Background: Empty nose syndrome (ENS) is a syndrome of paradoxical nasal obstruction that is thought to be mostly caused by inappropriate turbinate procedures. This study aimed to investigate depression- and anxiety-associated psychological symptoms in patients with ENS before and after surgical reconstruction, and to compare them with those of control subjects. Methods: Patients with ENS were prospectively enrolled. The Sino-Nasal Outcome Test-25 (SNOT-25), Empty Nose Syndrome 6-item questionnaire (ENS6Q), Beck Depression Inventory-II (BDI-II), and Beck Anxiety Inventory (BAI) were used to evaluate the participants before and after reconstruction surgery with submucosal Medpor implantation (Stryker, Kalamazoo, MI), as well as control subjects at enrollment. Results: Forty patients with ENS and forty age- and sex-matched controls were recruited. Patients with ENS experienced significant improvement in SNOT-25, ENS6Q, BDI-II, and BAI scores after surgery, but all were significantly greater than those in the control group. Nine patients with ENS (22.5%) had postoperative residual psychological symptoms. Preoperative BDI-II and BAI scores were significant predictors of postoperative residual psychological symptoms. The optimal cut-off value was BDI-II > 28.5 (sensitivity, 77.8%; specificity, 77.4%) in receiver operating characteristic curve analysis. Conclusions: The nasal and psychological evaluations in patients with ENS significantly improved after nasal reconstruction surgery, but both were significantly greater than those in the control group. Identifying individuals who may experience postoperative residual symptoms and providing a multimodal approach, including surgical reconstruction and psychiatric treatment, are suggested.

Abstract
BACKGROUND Empty nose syndrome (ENS) is characterized by paradoxical nasal obstruction that usually occurs after turbinate surgery. Patients with ENS may also experience significant psychiatric symptoms and sleep dysfunction, which negatively affect the quality of life of affected subjects. This study aimed to evaluate sleep impairment and sleepiness in patients with ENS. METHODS Patients with ENS and control participants were recruited prospectively. The Sino-Nasal Outcome Test-25 (SNOT-25), Empty Nose Syndrome 6-item Questionnaire (ENS6Q), Epworth Sleepiness Scale (EpSS), and modified sleep quality index (MSQI) were used to evaluate the participants before and after nasal surgery. RESULTS Forty-eight patients with ENS and forty-eight age- and sex-matched control subjects were enrolled. The SNOT-25, ENS6Q, EpSS, and MSQI scores in the ENS group were all significantly higher than those in the control group before and after surgery. After surgery, ENS patients all exhibited significant improvements in SNOT-25, ENS6Q, EpSS, and MSQI scores. Regression analysis revealed that SNOT-25 score was a significant predictor of EpSS and MSQI in preoperative evaluations. ENS patients experiencing daytime sleepiness suffered from significantly more "dryness of nose" and "suffocation" than those not experiencing daytime sleepiness. CONCLUSIONS Patients with ENS experienced significantly impaired sleep quality and sleepiness. Nasal reconstruction surgery improved the sleep quality of ENS patients. The severity of sleep dysfunction is associated with the severity of ENS symptoms. Recognizing individuals with significant sleep impairment and sleepiness and providing appropriate management are critical issues for ENS patients.

Abstract
PurposeNasal septoplasty is one of the most common surgical procedures in otorhinolaryngology and optimising both patient selection and the surgery is a challenge. The Nordic countries have similar public healthcare systems and comparable populations in terms of size.MethodsThis is a review of studies of outcome and predictors related to septoplasty from Denmark, Finland, Norway and Sweden, published during the last decade. The aim of this review was to identify areas in need of further research to meet the challenges of septoplasty in the Nordic countries with reference to international data.ResultsPostoperative patient satisfaction at 6–12 months was reported in around 2/3 of the patients and well in line with international data. Patients with more severe symptoms had a higher chance of improvement. Lack of standardisation in patient selection, surgical methods and skills, and follow up procedures, still makes it difficult to explain the 25% failure rate in septoplasty surgery.ConclusionThis review of the Nordic studies from the last decade shows that septoplasty in general is effective in relieving nasal obstruction. There is a need for studies addressing the standardisation of diagnostic tools and algorithms and the systematic and continuous implementation of follow-up of the surgical results at both departmental and personal level. This includes an awareness of how surgical skills in septoplasty are obtained and maintained.

Identifying Obstructive Sleep Apnoea in Patients with Empty Nose Syndrome. Diagnostics (Basel) 2022; 12:diagnostics12071720. [PMID: 35885624 PMCID: PMC9323833 DOI: 10.3390/diagnostics12071720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 07/01/2022] [Accepted: 07/12/2022] [Indexed: 11/17/2022] Open
Abstract
Obstructive sleep apnoea (OSA) is characterised by repetitive episodes of upper airway collapse and breathing cessation during sleep. Empty nose syndrome (ENS) is a surgically iatrogenic phenomenon of paradoxical nasal obstruction despite an objectively patent nasal airway. This study aimed to investigate sleep quality and the presence of OSA in ENS patients. Forty-eight ENS patients underwent full-night polysomnography. Total nasal resistance (TNR) was determined using anterior rhinomanometry. Symptoms and quality of life were evaluated by the empty nose syndrome 6-item questionnaire (ENS6Q), Sino-Nasal Outcome Test-22 (SNOT-22), and Epworth Sleepiness Scale questionnaires (ESS). Fourteen, twelve, and fourteen patients had mild, moderate, and severe OSA, respectively. The apnoea–hypopnoea index (AHI) and the lowest SpO2 were 23.8 ± 22.4/h and 85.9 ± 11.1%, respectively. N1, N2, N3 and rapid-eye-movement sleep comprised 30.2 ± 16.9%, 47.3 ± 15.5%, 2.1 ± 5.4%, and 20.0 ± 8.1% of the total sleep time. Body mass index, neck circumference, serum total immunoglobulin E, and ENS6Q score were significantly associated with AHI in the regression analysis. The ENS6Q scores correlated positively with AHI, arousal index, and ESS score, but negatively with TNR. ENS patients showed a high OSA prevalence and significant sleep impairment. The extent of OSA was associated with obesity levels and ENS symptom severity. The ENS6Q scores correlated negatively with nasal resistance, and positively with arousal frequency and daytime sleepiness. The recognition of individuals experiencing marked OSA and provision of appropriate intervention is critical to preventing long-term morbidity and mortality, and improving therapeutic outcomes in ENS patients.

Abstract
OBJECTIVES Patients with empty nose syndrome (ENS) suffer from paradoxical nasal obstruction with a patent objective nasal airway. ENS may result from the excessive surgical reduction of the turbinate tissue. ENS patients also experience significant psychological symptoms such as anxiety and depression. In this study, we aimed to evaluate the prevalence of suicidal thoughts in ENS patients and to characterize these patients for early identification. STUDY DESIGN Prospective case series. METHODS Patients with ENS were prospectively recruited for this study. The Sino-Nasal Outcome Test-25 (SNOT-25), Empty Nose Syndrome 6-item Questionnaire (ENS6Q), Beck Anxiety Inventory (BAI), and Beck Depression Inventory-II (BDI-II) were used to assess ENS patients before and 6 months after nasal reconstruction surgery. RESULTS Sixty-two patients with ENS were enrolled. Suicidal thoughts were identified in 23 ENS patients preoperatively and in four patients postoperatively. ENS patients with suicidal thoughts rated significantly higher in the SNOT-25, ENS6Q, BDI-II, and BAI total scores than those without suicidal thoughts (all P < .05). "Nose feels too open" was the item in ENS6Q that was significantly more severe in ENS patients with suicidal thoughts than those without suicidal thoughts (P < .001). CONCLUSIONS Suicidal thoughts are frequently identified in patients with ENS. ENS patients with suicidal thoughts experienced significantly more severe symptoms, impaired quality of life, and psychological burden than those without suicidal thoughts. Recognizing individuals who may carry suicidal thoughts and provide appropriate psychological interventions is critical to prevent tragedy. LEVEL OF EVIDENCE 4.

Abstract
OBJECTIVES Atrophic rhinitis (AR) and empty nose syndrome (ENS) are chronic diseases characterized by a paradoxical nasal obstruction. These rare syndromes tend to occur after nasal surgery of the inferior turbinates in ENS and can be idiopathic in AR. Medical treatments alone are often insufficient. Surgical options are challenging and numerous resorbable and nonresorbable implants have been described in small series, with as many surgical techniques described. Whereas current surgical procedures are for risk of extrusions, graft rejections or poor lasting results, the use of GlassBONE™ (Sodimed®, Avignon, France), a bioactive glass, for a vestibular approach in AR and ENS has never been reported for this indication. METHODS We described an original technique of nasal submucoperiosteal bilateral ceramic glass implantation in two patients with AR and ENS. RESULTS The two cases presented a postoperative satisfying endoscopic and sinus CT-scan results with filling of the nasal cavities, with less crusts and a complete wound healing. They had no short-term complications. CONCLUSION This innovative approach is easily feasible and could be an option considered for the surgical management of AR and ENS. Level of evidence: 4.

Abstract
We look back at the end of what soon will be seen as an historic year, from COVID-19 to real-world introduction of biologicals influencing the life of our patients. This review describes the important findings in Rhinology over the past year. A large body of evidence now demonstrates loss of sense of smell to be one of the most common symptoms of COVID-19 infection; a meta-analysis of 3563 patients found the mean prevalence of self-reported loss to be 47%. A number of studies have now shown long-term reduced loss of smell and parosmia. Given the high numbers of people affected by COVID-19, even with the best reported recovery rates, a significant number worldwide will be left with severe olfactory dysfunction. The most prevalent causes for olfactory dysfunction, besides COVID-19 and upper respiratory tract infections in general, are trauma and CRSwNP. For these CRSwNP patients a bright future seems to be starting with the development of treatment with biologics. This year the Nobel prize in Medicine 2021 was awarded jointly to David Julius and Ardem Patapoutian for their discoveries of receptors for temperature and touch which has greatly enhanced our understanding of nasal hyperreactivity and understanding of intranasal trigeminal function. Finally, a new definition of chronic rhinitis has been proposed in the last year and we have seen many papers emphasizing the importance of endotyping patients in chronic rhinitis and rhinosinusitis in order to optimise treatment effect.

Abstract
OBJECTIVE The pathophysiology of empty nose syndrome (ENS) remains unclear despite significant research. The pathophysiologic mechanism of ENS was systematically reviewed. DATA SOURCES MEDLINE and Embase. REVIEW METHODS Data were systematically reviewed for studies that provided original data on pathophysiology. RESULTS A total of 2476 studies were screened, and 19 met the inclusion criteria: 13 case-control and 6 cross-sectional. Nine pathophysiologic themes were identified.• Demographics: ENS symptoms had no relationship with climatic factors.• Symptomatology: ENS patients demonstrated high symptom severity.• Mental health: Anxiety and depression including hyperventilation were reported in >50% of ENS patients and correlated with ENS symptom severity.• Anatomic features: Structural changes in response to turbinate surgery were similar between ENS and non-ENS patients.• Airflow analysis: Airflow parameters were similar between ENS and non-ENS patients after turbinate surgery. On computational fluid dynamic analysis, differences were found on multiple outcomes.• Diagnostic testing: The menthol detection test was impaired in ENS, and cotton placement in the airway improved ENS symptoms.• Cognitive function: Functional magnetic resonance imaging showed activation in emotional processing area during breathing.• Olfactory function: Subjective impairment was reported in ENS, but quantitative measures were similar to non-ENS patients.• Mucosal physiology/innate immunity: Turbinate histopathology in ENS showed a tissue-remodeling pattern. Nasal nitric oxide level was lower in ENS patients. CONCLUSION There is evidence of high comorbid mental health disorders in ENS patients. An abnormal trigeminal-thermoreceptor response may be present in some patients. The influence of altered airflow and the evidence of surgery as the cause for ENS are unclear.

Abstract
BACKGROUND Olfactory dysfunction, such as hyposmia, is a significant symptom of empty nose syndrome (ENS). The efficacy of surgical intervention in olfaction improvements for ENS has not been investigated extensively. OBJECTIVE The aim of this study was to evaluate changes in olfaction after surgical treatment for ENS. METHODS This prospective cohort study at a tertiary medical center enrolled patients with ENS indicated for surgical treatment between June 2015 and June 2019. The Sniffin' Sticks 12-items odor identification test (SS-12) and subjective olfaction rating were completed by patients before and after surgery to assess olfaction. RESULTS A total of 40 patients completed the survey both before and after surgical treatment. Prior to surgery, 25% of the patients had olfactory dysfunction detected by SS-12, whereas 80% of the patients reported a reduction in olfactory function by subjective rating. The degree of olfactory dysfunction by both assessments significantly improved following surgery. The age was a significant predictor of postoperative improvement. CONCLUSION Surgical treatment is helpful in improving olfaction in patients with ENS who commonly suffer from olfactory dysfunction. Younger patients may benefit more from surgical intervention in aspect of olfaction.

Abstract
OBJECTIVES /HYPOTHESIS Empty nose syndrome (ENS) is a complicated condition currently thought to be caused by excessive surgical resection of turbinate tissue. Patients with ENS experienced significant psychological symptoms, such as depression and anxiety. This study aimed to evaluate the impact of the psychological burden on the surgical outcome of ENS. STUDY DESIGN Prospective case series in a tertiary medical center. METHODS Patients with ENS were prospectively recruited between 2015 and 2018. Validated instruments including the Sinonasal Outcome Test-25 (SNOT-25), Beck Depression Inventory-II (BDI-II), and Beck Anxiety Inventory (BAI) were used to evaluate patients with ENS prior to and 3, 6, and 12 months after nasal reconstruction surgery with submucosal Medpor implantation. RESULTS A total of 54 ENS patients were enrolled during the study period. All three evaluations revealed significant improvement, and symptoms stabilized 3 months after surgery. Six months post-operatively, SNOT-25 scores were significantly associated with the pre-operative BDI-II and BAI scores (β = 0.64 and 0.87; P = .006 and <.001, respectively). Multivariate regression model revealed that only BAI scores were significantly associated with the six-month post-operative SNOT-25 scores (adjusted β = 0.49, P = .036). Moreover, Spearman's correlation found close relationships between the post-operative SNOT-25 and the post-operative BDI-II and BAI scores (rs = 0.751 and 0.884, both P < .001). CONCLUSIONS Psychological evaluation can help predict surgical outcomes and identify patients with residual disease. These findings emphasize the importance of screening for psychological symptoms and structuring care by including psychological therapy in addition to surgery. LEVEL OF EVIDENCE 4.

METHODS Consecutive patients with ENS who were diagnosed and received surgical intervention after failure of conservative management were included. Patients with benign pituitary gland tumor receiving transsphenoidal excision were enrolled as control group. Biopsy of inferior turbinate was obtained during surgery for histological review and immunohistochemical staining. RESULTS Seventeen patients with ENS and six patients as a control group were established for structured histological review. Patients with ENS presented significantly more squamous metaplasia, a higher rate of submucosal fibrosis, and a lower submucosal gland number grading. Additionally, a unique histological change called goblet cell metaplasia was found in the ENS group. The respiratory epitheliums of ENS were mostly intact with preservation of ciliated cells and goblet cells. The ENS group had a significantly lower expression level of TRPM8. CONCLUSIONS The nasal mucosa of ENS experienced some airway remodeling and thermoreceptors downregulation, which contribute to clinical symptoms. The distinct histology of ENS included preserved respiratory epithelium and goblet cell metaplasia, accompanying with characteristics similar to atrophic rhinitis. Biopsy of the inferior turbinate may help diagnose ENS. LEVEL OF EVIDENCE 4 Laryngoscope, 131:E14-E18, 2021.

Abstract
BackgroundThe last 5 years have seen a surge of both clinical and scientific interest in empty nose syndrome (ENS). Although ENS is still considered a controversial diagnosis plagued by a lack of standardized diagnostic criteria, ENS is increasingly becoming recognized as a legitimate, physiologic disease entity. As such, it is important for clinicians to understand the most up-to-date diagnostic tools to assess ENS, confirm the diagnosis, and create a more standardized means to counsel these complex patients.ObjectiveContemporary literature review to discuss diagnostic modalities in the evaluation of ENS, in order to introduce evidence-based diagnostic criteria.MethodsA systematic review was conducted in PubMed and Embase (2013–2019) using the search term “empty nose syndrome” to identify peer-reviewed articles on the topic of ENS. Articles advancing contemporary methods of ENS diagnosis and testing were included. A quality assessment was conducted using The Rational Clinical Examination Levels of Evidence.ResultsThe novel development of the Empty Nose Syndrome 6 Questionnaire (ENS6Q) offers the clinician a validated patient-reported outcome measure to supplement history and physical examination. The in-office cotton test, performed by placing an endoscopically directed cotton plug in the site of tissue loss, may help to identify patients who may benefit from turbinate augmentation. Tools such as the sinus computed tomography scan, computational fluid dynamics, and intranasal trigeminal nerve function testing currently have insufficient evidence to support routine use in the workup of ENS. Up to 66% of ENS patients present with comorbid anxiety or depression.ConclusionThe ENS6Q and cotton test assist in creating a standardized approach to the evaluation of patients suspected of ENS. These instruments should be used as an adjunct, rather than the sole criteria, on which to ascertain the presumptive diagnosis. Patients suspected of ENS should be screened for comorbid psychological dysfunction.

Abstract
The aim of this study is to investigate the effect of olfactory dysfunction (OD) on the two other chemical senses, namely gustation and the intranasal trigeminal system. Taste and trigeminal function were analyzed in a retrospective cross-sectional study of 178 participants with OD (n = 78 posttraumatic, n = 42 idiopathic, n = 27 post-infectious and n = 31 chronic rhinosinusitis (CRS) OD). All patients had been investigated for OD at our smell and taste outpatient clinic. Evaluation of olfaction was performed by means of the Sniffin' Sticks test (odor threshold, odor discrimination and odor identification), whereas gustatory function was assessed with the Taste Strips test and the intranasal trigeminal sensitivity by means of the lateralization task. The degree of olfactory impairment was found to depend on the cause of OD, but not on patients' age. Patients with posttraumatic OD showed lower olfactory function than patients with idiopathic, post-infectious and CRS OD (p = 0.01). Gustatory and trigeminal sensitivity in turn depended on age rather than the cause of olfactory dysfunction. Partial correlations between olfactory, gustatory, and trigeminal scores, with age as covariate, were significant, showing a decrease of taste and trigeminal function proportional to the OD (p < 0.05). The present data suggest that the three chemical senses are closely connected for humans underlining that in case of OD the remaining chemical senses (taste, trigeminal function) tend to decrease rather than compensate as this is seen for sensory loss in other modalities. This finding has direct clinical implications and importance when dealing with smell and taste disorders.

Computational fluid dynamic analysis of aggressive turbinate reductions: is it a culprit of empty nose syndrome? Int Forum Allergy Rhinol 2019; 9:891-899. [PMID: 31077575 DOI: 10.1002/alr.22350] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Revised: 04/02/2019] [Accepted: 04/09/2019] [Indexed: 11/06/2022]
Abstract
BACKGROUND Empty nose syndrome (ENS) remains highly controversial, with aggressive inferior turbinate reduction (ITR) or mucociliary dysfunction frequently implicated. However, the appropriate degree of ITR is highly debatable. METHODS We applied individual computed tomography (CT)-based computational fluid dynamics (CFD) to 5 patients receiving relatively aggressive ITR but with no ENS symptoms, and compared them to 27 symptomatic ENS patients who all had histories of aggressive ITRs, and 42 healthy controls. Patients' surgical outcomes were confirmed with 22-item Sino-Nasal Outcome Test (SNOT-22) (ITR: 6.40 ± 4.56; ENS: 58.2 ± 15.9; healthy: 13.2 ± 14.9), Nasal Obstruction Symptom Evaluation (NOSE) scores (ITR: 4.00 ± 2.24; ENS: 69.4 ± 17.1; healthy: 11.9 ± 12.9), and Empty Nose Syndrome 6-Item Questionnaire (ENS6Q) (≥11 for ENS). RESULTS Both aggressive ITR without ENS symptoms and symptomatic ENS patients had significantly lower nasal resistance (ITR: 0.059 ± 0.020 Pa·s/mL; ENS: 0.052 ± 0.015 Pa·s/mL; healthy: 0.070 ± 0.021 Pa·s/mL) and higher cross-sectional areas surrounding the inferior turbinate (ITR: 0.94 ± 0.21 cm2 ; ENS: 1.19 ± 1.05 cm2 ; healthy: 0.42 ± 0.22 cm2 ) than healthy controls. The lack of significant differences among patient groups indicated similar degrees of surgeries between ITR with and without ENS symptom cohorts. However, symptomatic ENS patients have paradoxical significantly less airflow in the inferior meatus (ITR: 47.7% ± 23.6%; ENS: 25.8% ± 17.6%; healthy: 36.5 ± 15.9%; both p < 0.01), but higher airflow around the middle meatus (ITR: 49.7% ± 22.6%; ENS: 66.5% ± 18.3%; healthy: 49.9% ± 15.1%, p < 0.0001) than aggressive ITR without symptoms and controls. Aggressive ITR patients have increased inferior meatus airflow as expected (p < 0.05). This imbalanced airflow produced less inferior wall-shear-stress distribution among symptomatic ENS patients only (ITR: 42.45% ± 11.4%; ENS: 32.2% ± 12.6%; healthy: 49.7% ± 9.9%). ENS patients (n = 12) also had impaired nasal trigeminal function, as measured by menthol lateralization detection thresholds (ITR: 15.2 ± 1.2; ENS: 10.3 ± 3.9; healthy: 13.8 ± 3.09, both p < 0.0001). Surprisingly, aggressive ITR patients without ENS symptoms have better menthol lateralization detection thresholds (LDTs) than healthy controls. CONCLUSION Although turbinate tissue loss is linked with ENS, the degree of ITR that might distinguish postoperative patient satisfaction in their nasal breathing vs development of ENS symptoms is unclear. Our results suggest that a combination of distorted nasal aerodynamics and loss of mucosal sensory function may potentially lead to ENS symptomology.

Abstract
Many odors activate the intranasal chemosensory trigeminal system where they produce cooling and other somatic sensations such as tingling, burning, or stinging. Specific trigeminal receptors are involved in the mediation of these sensations. Importantly, the trigeminal system also mediates sensitivity to airflow. The intranasal trigeminal and the olfactory system are closely connected. With regard to central nervous processing, it is most interesting that trigeminal stimuli can activate the piriform cortex, which is typically viewed as the primary olfactory cortex. This suggests that interactions between the two systems may form at a relatively early stage of processing. For example, there is evidence showing that acquired olfactory loss leads to reduced trigeminal sensitivity, probably on account of the lack of interaction in the central nervous system. Decreased trigeminal sensitivity may also be responsible for changes in airflow perception, leading to the impression of congested nasal airways.

Abstract
BACKGROUND Empty nose syndrome (ENS) is a rare and debilitating disease with a controversial definition, etiology, and treatment. One puzzling fact is that patients who undergo an endoscopic endonasal approach (EEA) often have resection of multiple anatomic structures, yet seldom develop ENS. In this pilot study, we analyzed and compared the computational fluid dynamics (CFD) and symptoms among post-EEA patients, ENS patients, and healthy subjects. METHODS Computed tomography scans of 4 post-EEA patients were collected and analyzed using CFD techniques. Two patients had significant ENS symptoms based on results of the Empty Nose Syndrome 6-item Questionnaire (score >11), whereas the other 2 were asymptomatic. As a reference, their results were compared with previously published CFD results of 27 non-EEA ENS patients and 42 healthy controls. RESULTS Post-EEA patients with ENS symptoms had a similar nasal airflow pattern as non-EEA ENS patients. This pattern differed significantly from that of EEA patients without ENS symptoms and healthy controls. Overall, groups with ENS symptoms exhibited airflow dominant in the middle meatus region and a significantly lower percentage of airflow in the inferior turbinate region (EEA with ENS, 17.74 ± 4.00% vs EEA without ENS, 51.25 ± 3.33% [t test, p < 0.02]; non-EEA ENS, 25.8 ± 17.6%; healthy subjects, 36.5 ± 15.9%) as well as lower peak wall shear stress (EEA with ENS, 0.30 ± 0.13 Pa vs EEA without ENS, 0.61 ± 0.03 Pa [p = 0.003]; non-EEA ENS, 0.58 ± 0.24 Pa; healthy subjects, 1.18 ± 0.81 Pa). CONCLUSION These results suggest that turbinectomy and/or posterior septectomy may have a varying functional impact and that ENS symptoms go beyond anatomy and correlate with aerodynamic changes. The findings open the door for CFD as a potential objective diagnosis tool for ENS.

Abstract
BACKGROUND Abnormal nasal aerodynamics or trigeminal functions have been frequently implicated in the symptomology of empty nose syndrome (ENS), yet with limited evidence. METHODS Individual computed tomography (CT)-based computational fluid dynamics (CFD) was applied to 27 ENS patients to simulate their nasal aerodynamics and compared with 42 healthy controls. Patients' symptoms were confirmed with Empty Nose Syndrome 6-item Questionnaire (ENS6Q), 22-item Sino-Nasal Outcome Test (SNOT-22), and Nasal Obstruction Symptom Evaluation (NOSE) scores. Nasal trigeminal sensitivity was measured with menthol lateralization detection thresholds (LDTs). RESULTS ENS patients had significantly lower (∼25.7%) nasal resistance and higher (∼2.8 times) cross-sectional areas compared to healthy controls (both p < 0.001). Despite inferior turbinate reductions, CFD analysis demonstrated that ENS patients had increased airflow concentrated in the middle meatus region (66.5% ± 18.3%) compared to healthy controls (49.9% ± 15.1%, p < 0.0001). Significantly less airflow (25.8% ± 17.6%) and lower peak wall shear stress (WSS) (0.58 ± 0.24 Pa) were found in the inferior meatus (vs healthy: 36.5% ± 15.9%; 1.18 ± 0.81 Pa, both p < 0.05), with the latter significantly correlated with the symptom scores of ENS6Q (r = -0.398, p = 0.003). Item-wise, complaints of "suffocation" and "nose feels too open" were also found to be significantly correlated with peak WSS around the inferior turbinate (r = -0.295, p = 0.031; and r = -0.388, p = 0.004, respectively). These correlations were all negative, indicating that less air-mucosal stimulations resulted in worse symptom scores. ENS patients (n = 12) also had impaired menthol LDT when compared to healthy controls (p < 0.0001). CONCLUSION This is the first CFD examination of nasal aerodynamics in a large cohort of ENS patients. The results indicated that a combination of loss of neural sensitivity and poorer inferior air-mucosal stimulation may potentially lead to ENS symptomology.
