Office-based rhinologic surgery: A modern experience with operative techniques under local anesthetic

Assessing the safety and tolerability of rhinologic surgery under local anesthetic: an 8-year retrospective analysis

PURPOSE

Office-based rhinologic procedures (OBRP) have become widely available in North America due to technological advances and appropriate patient selection. Nevertheless, the literature exploring the safety of these procedures remains limited. The objective of this study was to further evaluate the safety, tolerability and efficacy of these procedures with a more robust sample size to allow for capture of rare events.

METHODS

A retrospective chart review of all patients who underwent OBRP from May 2015 to March 2023. Information regarding patient demographics, the indication for surgery, wait time, tolerability, intra- and postoperative complications, need for revisions, and type of revision (if applicable) was recorded.

RESULTS

1208 patients underwent OBRP during the study period. No patients were excluded. These included turbinoplasties (35%), endoscopic sinus surgeries (ESS) (26%), septoplasties (15%), nasal fracture reductions (7%), and a variety of other procedures. For ESS procedures, the anterior ethmoids and the maxillary sinuses were the most common sinuses treated. 1.1% of procedures were aborted prior to completion. The post-operative complication rate was 3.2%, with 2 major complications (significant bleeding and sepsis) encountered. The mean follow-up overall was 11 months and for ESS it was 15.8 months.

CONCLUSION

Office-based rhinologic procedures are well tolerated and safe for the appropriate patient and associated with shorter wait-times as well as avoidance of general anesthesia. The complication rates are similar to or lower than previously reported rates for rhinologic surgeries done in the operating room. The low rates of revision surgery also demonstrate the efficacy of these procedures.

Functional nasal surgery in the office-based setting

Objective

Nasal obstruction is a very common problem often addressed by functional nasal surgery. Increasingly, these procedures are being performed in the office setting secondary to decreased down time, cost, and obviation of general anesthesia. Our goal with this review is to discuss how to appropriately select patients for office-based procedures, what procedures may be considered, and current outcomes with in-office functional nasal surgery.

Data Sources

PubMed, Scopus, Google Scholar.

Methods

Research databases were searched for articles discussing techniques for performing functional nasal surgery in an office setting, and outcomes of various in-office functional nasal procedures.

Results

Studies found and included in this review discuss many aspects of office-based functional nasal surgery, including practical points on patient selection and office set-up, what procedures can safely be performed, and outcomes of different techniques to address specific problems. Broadly, procedures amenable to performance in the office address the internal and external nasal valves, the nasal septum, and the inferior turbinates.

Conclusion

A wide range of techniques to aaddress the nasal valves, septum, and inferior turbinates can be performed in a safe and effective manner without the need for an operative suite.

Impact of Prolonged Operative Time on Complications Following Endoscopic Sinonasal Surgery

OBJECTIVE

To determine how prolonged operative time (POT) impacts 30-day outcomes in patients undergoing endoscopic sinonasal surgery (ESNS).

STUDY DESIGN

Retrospective study.

METHODS

Data from patients who underwent ESNS (nonsinus, sinus, and extended sinus) between 2005 to 2018 were collected from the American College of Surgeons National Surgical Quality Improvement database. Univariate and multivariate analyses were performed to evaluate the effect of POT on postoperative outcomes.

RESULTS

Among 1,994 ESNS cases, 495 nonsinus procedures, 1,191 sinus procedures, and 308 extended sinus procedures were identified. Median OT was 90 minutes (interquartile range [IQR], 51-165 minutes) for nonsinus procedures, 113 minutes (IQR, 66-189 minutes) for sinus procedures, and 187 minutes (IQR, 137-251 minutes) for extended sinus procedures. Other than older age (P = .008), POT was not significantly associated with baseline demographics and comorbidities for patients undergoing non-sinus procedures. Older age (P < .001), White and Black race (P < .001), ASA physical classifications III or IV (P < .001), and several preoperative comorbidities, including obesity (P = .045), and hypertension (P < .001) were associated with POT for sinus procedures. Older age (P = .030), male sex (P = .010), and lower body mass index (P = .004) were associated with POT for extended sinus procedures. After risk-adjustment, POT was independently associated with prolonged hospital stay (LOS) for all procedure categories, and associated with overall surgical complications and postoperative bleeding for sinus and extended sinus procedures specifically.

CONCLUSION

POT is independently associated with several adverse outcomes following ESNS, including prolonged LOS, overall surgical complications, and bleeding. Preoperative planning should include optimizing modifiable patient risk factors for POT and identifying surgeon-specific factors to enhance surgical efficiency.

Long term outcomes of balloon sinuplasty for the treatment of chronic rhinosinusitis with and without nasal polyps

OBJECTIVES

The aim of this study was to evaluate the 4-year outcomes and effectiveness of balloon sinuplasty in the treatment of chronic rhinosinusitis (CRS).

MATERIAL AND METHODS

We evaluated the long-term outcomes in terms of symptoms, nasal endoscopy and computed tomography of 110 patients with CRS submitted to balloon sinuplasty in Centro Hospitalar do Funchal retrospectively. Sinus symptoms were determined by the Sino-Nasal Outcome Test (SNOT-22), endoscopic examination determined by Modified Lund Kennedy score (MLK) and computerized tomography scan of paranasal sinuses (CT-PNS) was evaluated through Lund Mackay scores (LM). Data was collected from 82 patients with chronic rhinosinusitis without nasal polyps (CRSsNP) and from 28 patients with nasal polyps (CRSwNP).

RESULTS

Local anesthesia procedures were performed in 45.5% of the patients. First follow up was obtained at 2 years (median 22.45 ± 13.6 months) and at 4 years (median 44.45 ± 14 months) after balloon sinuplasty. The mean baseline SNOT-22 score was of 50.26 ± 15.33 for patients with CRSsNP and 52.25 ± 18.06 in CRSsNP patients. Both scores were reduced to 7.00 ± 13.5 and 10.00 ± 22.50 at 4 years follow-up respectively. Baseline MLK score was 4.90 ± 2.12 for patients in CRSsNP group and 10.00 ± 2.00 in the CRSwNP group Both scores were reduced to 1.65 ± 1.67 and 4.86 ± 2.16. The overall mean average LM CT-PNS score was 8.71 ± 4.728 preoperatively for the CRSsNP and 16.18 ± 3.9 in patients with CRSwNP and were reduced to 1.00 ± 1.75 and 8.69 ± 4.6 after BSP. SNOT 22, MLK and LM scores showed consistent improvement over baseline at all time points until the end of the study (median 44.45 ± 14 months). Significant improvements were recorded at all time points in the patient's symptom score, nasal endoscopy scores and imaging scores (P < 0.0001).

CONCLUSION

Balloon sinuplasty appears to be safe and effective for the treatment of CRS with great long-term outcomes.

Office-Based Sinus Surgery for Cystic Fibrosis Chronic Rhinosinusitis

OBJECTIVE

Chronic rhinosinusitis (CRS) is nearly ubiquitous in the cystic fibrosis (CF) population, and many patients require multiple endoscopic sinus surgeries throughout their lifetime. Recent studies have demonstrated the profound pulmonary and systemic health benefits of comprehensive CRS treatment. Both endotracheal intubation with mechanical ventilation and inpatient hospital care represent significant risks for CF patients. The goal of this study is to evaluate the safety and feasibility of performing revision endoscopic sinus surgery for CF patients in the outpatient office setting using only local anesthesia to decrease the need for mechanical ventilation and inpatient hospitalization.

METHODS

This is a prospective cohort study conducted at a tertiary care academic medical center with a CF Foundation-accredited care center. Patients with CF and refractory CRS despite prior surgery and medical therapy were eligible for inclusion. Comprehensive revision ESS was performed in the office using only local anesthesia.

RESULTS

Five patients were enrolled and underwent revision endoscopic sinus surgery without complication. The average preoperative Sinonasal-Outcome Test-22 score was 52.0 ± 12.1 and the average preoperative Lund-Mackay score was 15.2 ± 3.8. No patients requested aborting the procedure early due to pain, discomfort, or any other reason. No subjects required prolonged observation or postoperative hospital admission.

CONCLUSION

This prospective pilot study is the first to demonstrate the safety and feasibility of performing comprehensive revision endoscopic sinus surgery for CF patients in the outpatient office setting using only local anesthesia.

In-office endoscopic nasal polypectomy: prospective analysis of patient tolerability and efficacy

Purpose

In-office rhinologic procedures have become popularised in the last decade, especially in North America. Endoscopic nasal polypectomy under local anaesthesia offers instant relief in selected patients with obstructive chronic rhinosinusitis with nasal polyps. We aimed to analyse patient tolerability during the procedure while measuring its effectiveness.

Methods

A prospective study of patients who underwent in-office microdebrider-assisted polypectomy under local anaesthetic from September 2018 to November 2019 in a Spanish tertiary hospital was performed. The tolerability was measured by monitoring vital signs during the procedure and using a visual analogue scale posteriorly. The effectiveness was calculated through patient-reported outcomes (SNOT-22) and endoscopic evaluation 1 and 6 months follow-up.

Results

Forty-four patients were included, with a mean age of 60.7 years. The mean visual analogue scale score was 2.76 out of 10 points. Vital signs were steady overall, with a statistically significant reduction (p < 0.001) in systolic pressure during the procedure. Presyncope and epistaxis were among the few mild complications. However, we registered one major complication that required intensive care admission. There was a 64% reduction in the SNOT-22 score in the first month, with a maintained effect after 6 months. Patients with asthma and a higher polyp load were the subgroups that required more time to achieve significant improvement.

Conclusions

In-office polypectomy is a very effective technique that alleviates obstructive symptoms in patients with nasal polyposis, and it is generally safe and well tolerated when performed by an expert. However, rhinologists must be aware of potentially severe complications.

Minimally invasive surgery under local anaesthesia for chronic rhinosinusitis with nasal polyps: our experience in older adults

OBJECTIVE

This paper aims to report our experience with a minimally invasive surgical procedure for the treatment of chronic rhinosinusitis with nasal polyps, performed in a day-surgery setting under local anaesthesia.

METHODS

A retrospective study of 30 patients with chronic rhinosinusitis with nasal polyps was conducted. Sino-Nasal Outcome Test 22 and modified Lund-Kennedy scores were collected. Intra- and post-operative pain was evaluated using a 10-point visual analogue scale.

RESULTS

The mean Sino-Nasal Outcome Test 22 score decreased from 41.8 ± 15.8 pre-operatively to 13.3 ± 9.5 post-operatively (p < 0.001). Accordingly, the mean endoscopic score decreased from 6.8 ± 1.8 to 0.2 ± 0.7 (p < 0.001). The mean intra-operative pain score was 2.9 ± 3.2, and 29 patients (96.7 per cent) reported no pain in the post-operative period (visual analogue scale score = 0).

CONCLUSION

Our study confirms that minimally invasive surgery represents a safe, repeatable procedure that results in remarkable subjective and objective improvement, without intra- and post-operative pain or discomfort.

Hemodynamic changes in patients undergoing office-based sinus procedures under local anesthesia

BACKGROUND

The objective of this study is to characterize changes in hemodynamics, pain, and anxiety during office-based endoscopic sinus procedures performed under local anesthesia.

METHODS

We conducted a prospective study of adults undergoing in-office endoscopic sinus procedures under local anesthesia. Patients with American Society of Anesthesiologists (ASA) Physical Status Classification System class 1 or 2 were included. Anesthesia was administered by topical 4% lidocaine/oxymetazoline and submucosal injection of 1% lidocaine/1:200,000 epinephrine. Vital signs and pain were measured at baseline, postinjection, and 5-minute intervals throughout the procedure. Anxiety levels were scored using the State-Trait Anxiety Inventory (STAI). Univariate and multivariate regression analyses were performed to identify factors significantly associated with changes in each hemodynamic metric.

RESULTS

Twenty-five patients were studied. This cohort was 52% male, mean age of 57.8 ± 14.4 years, and Charlson Comorbidity Index (CCI) median of 2. Mean procedure duration was 25.0 ± 10.3 minutes. Mean maximal increase in systolic blood pressure (SBP) was 24.6 ± 17.8 mmHg from baseline. Mean maximal heart rate increase was 22.8 ± 10.8 beats per minute (bpm) from baseline. In multivariate regression analysis, when accounting for patient age, cardiac comorbidity, CCI, and ASA, older age was significantly associated with an increase of >20 mmHg in SBP (p = 0.043). Mean pain score during procedures was 1.5 ± 1.3 with a mean maximum of 4.0 ± 2.6. STAI anxiety scores did not change significantly from preprocedure to postprocedure (32.8 ± 11.6 to 31.0 ± 12.6, p = 0.46). No medical complications occurred.

CONCLUSION

Although patients appear to tolerate office procedures well, providers should recognize the potential for significant fluctuations in blood pressure during the procedure, especially in older patients.

Office-Based Sinus Surgery

Office-based rhinologic procedures have seen a dramatic rise in incidence over the last decade. It is crucial to select appropriate patients and understand which pathologies may be amenable to in-office procedures. It behooves the otolaryngologist to be familiar with the array of technologic advances that are expanding the limits of office-based rhinology and to have a solid understanding of the technical nuances of using these technologies in the clinic. This article highlights the issues associated with some of the more common office-based sinus procedures, and provides practical information on set-up and reimbursement.

In-office Functional Nasal Surgery

Nasal airway obstruction is a common complaint encountered by the otolaryngologist. In-office nasal procedures are becoming increasingly popular and should be considered for patients desiring immediate treatment without the adverse effects of general anesthesia, operating room costs, or scheduling delays. This article discusses the factors in patient selection, room setup, and other considerations. The options available for in-office treatment of nasal valve repair are discussed, including turbinoplasty, septoplasty, and nasal valve repair/functional rhinoplasty-type techniques described in the literature.

Assessment and Treatment of Pain during In-Office Otolaryngology Procedures: A Systematic Review

OBJECTIVE

To qualitatively assess practices of periprocedural pain assessment and control and to evaluate the effectiveness of interventions for pain during in-office procedures reported in the otolaryngology literature through a systematic review.

DATA SOURCES

PubMed, CINAHL, and Web of Science searches from inception to 2018.

REVIEW METHODS

English-language studies reporting qualitative or quantitative data for periprocedural pain assessment in adult patients undergoing in-office otolaryngology procedures were included. Risk of bias was assessed via the Cochrane Risk of Bias or Cochrane Risk of Bias in Non-Randomized Studies of Interventions tools as appropriate. Two reviewers screened all articles. Bias was assessed by 3 reviewers.

RESULTS

Eighty-six studies describing 32 types of procedures met inclusion criteria. Study quality and risk of bias ranged from good to serious but did not affect assessed outcomes. Validated methods of pain assessment were used by only 45% of studies. The most commonly used pain assessment was patient tolerance, or ability to simply complete a procedure. Only 5.8% of studies elicited patients' baseline pain levels prior to procedures, and a qualitative assessment of pain was done in merely 3.5%. Eleven unique pain control regimens were described in the literature, with 8% of studies failing to report method of pain control.

CONCLUSION

Many reports of measures and management of pain for in-office procedures exist but few employ validated measures, few are standardized, and current data do not support any specific pain control measures over others. Significant opportunity remains to investigate methods for improving patient pain and tolerance of in-office procedures.

Modeling Microdebrider-Mediated Ophthalmic Damage: A Word of Caution in Endoscopic Sinus Surgery

Background

The microdebrider has become nearly universal in the treatment of sinonasal pathology; however, recent case reports have demonstrated the potential for major ophthalmic complications. The goal of this study was twofold: 1) determine the anatomical proximity of ophthalmic structures to the paranasal sinuses, and 2) assess the timeframe at which ophthalmic injury may occur with the use of a microdebrider during FESS utilizing a cadaveric model.

Methodology/Principal

Computed tomography scans from 50 patients were accessed retrospectively. The distances between the lamina papyracea (LP) and orbital structures were determined at varying depths. Seven cadavers (14 sides) were studied using three microdebrider systems operated by otolaryngology residents. Following removal of a window of LP, the time from activation of the microdebrider on the periorbita until transection of the medial rectus (MR), optic nerve (ON), and to aspiration of the globe were measured.

Results

The mean distance between the LP and MR at the level of the anterior aspect of the anterior ethmoid and basal lamella were 3.59 ±1.2mm and 1.5 ±0.8mm, respectively. The mean distance between the LP and ON at the level of the basal lamella was 8.1 ±2.1mm. Mean transection times for the MR and ON were 13.4 ± 7.3 seconds and 37.3 ± 9.2 seconds, respectively, with minimum times of 4 seconds and 26 seconds.

Conclusions

The proximity of orbital structures to the paranasal sinuses and the rapidity of ophthalmic damage following violation of the periorbita reaffirms the need for cautious use of the microdebrider during FESS.

Practice Patterns in Office-Based Rhinology: Survey of the American Rhinologic Society

BACKGROUND

Recent years have witnessed significant expansion in office-based rhinology. This study assesses practice patterns of the American Rhinologic Society (ARS) membership regarding office-based rhinologic procedures.

METHODS

A 24-item survey was disseminated to the ARS membership from March 15 to May 31, 2016.

RESULTS

A total of 157 physicians (11.9%) completed the survey. Office-based rhinologic procedures were performed by 99% of respondents, with sinonasal debridements (99%), polypectomy (77%), and balloon sinus ostial dilation (56%) being the most common. During a typical month, the number of sinonasal debridements was 0-10 in 23%, 11-20 in 34%, 21-30 in 26%, and >30 in 18%. For polypectomy, 57% of the respondents utilized a microdebrider (reusable electric-24%, disposable vacuum-powered-21%, and both-12%), 36% endoscopic forceps, and 7% a combination of both. With respect to balloon ostial dilation, the frontal sinuses were the most frequently addressed (53%) followed by the maxillary (46%) and sphenoid (39%) sinuses. In-office ethmoidectomies, antrostomies, sphenoidotomies, and frontal sinusotomies without the use of the balloon were performed by 35%, 31%, 24%, and 21% of the respondents, respectively. Thirty percent of respondents used steroid-eluting sinus implants and 10% used computer-assisted surgical navigation in the office setting. Overall, 63% of respondents reported that the number of office-based rhinologic procedures they performed had increased over the last 5 years.

CONCLUSIONS

The present study illustrates the integration of office procedures into rhinologic clinical practice among ARS survey respondents. With ongoing technologic innovations, the scope of office-based rhinology will likely continue to expand in the years to come.

International survey and consensus (ICON) on ambulatory surgery in rhinology

OBJECTIVES

Day-case surgery is the gold standard to several surgical procedures in Rhinology. However, few data and guidelines have been published except in the Anglo-Saxon countries and France. The aim of this survey was to propose a list of issues arising during day-case surgery in order to analyze the different constraints encountered around the world.

MATERIAL AND METHOD

It was a prospective multicenter international email survey. The method was based on the formalized expert consensus methodology. A list of 11 issues was based on literature data and was sent by e-mail to 265 key opinion leaders (KOL) who attended the IFOS congress.

RESULTS

The response rate was 20% from 27 countries without statistical difference between continents concerning the score on each item. The mean age of KOL was 50±10 years. Their mean length of experience was 21±10 years. Issues in relation with technical resources and experience showed that the last time at which ambulatory surgery in the day is possible was 4:00 PM but responses varied depending the availability of technical resources. Bleeding or hematoma occurred most frequently between the third and fourth postoperative day whatever the surgical procedure. A strong agreement and consensus was obtained concerning the nasal packing, septal contention and their schedule of removal which were not a contraindication of day-case. Also 75% of participants were agreeing with a therapeutic education program to improve the performance of postoperative care and decrease readmission rates. A relative agreement without consensus were obtained for the distance between the day-case unit and home, the role of surgery duration and the impact of anticoagulant and/or antiplatelet drugs in overnight admission and readmission rates.

CONCLUSION

Practice varies widely owing to local organization constraints and the availability of a dedicated day-case unit seems to be the main limiting factor.
