RESUMO
Objectives: Single-use rhinolaryngoscopes were brought to market in 2019 as an alternative to traditional reusable scopes and have garnered interest across settings given portability and potential cost advantages. While single-use was previously evaluated compared to traditional devices, the overall impact to the consult experience for both users and patients has not been captured. Methods: Eighteen residents performed consults with both single-use and reusable rhinolaryngoscope systems on alternating weeks. A five-question cumulative survey administered across three assessment points over a 12-week period using a five-point rating system to rate favorability. Residents and patients also completed four-point scale surveys following procedure(s) to capture the consult experience. Statistical analyses were performed to measure significance differences between survey responses between the two systems. Results: Single-use rhinolaryngoscopes received higher overall ratings compared with reusables across each metric captured including overall consult time (4.3 vs. 2.2, p < .001), multiscope consults (4.4 vs. 3.1, p < .001), patient communication (4.6 vs. 2.1, p < .001), teaching opportunities (4.6 vs. 2.1, p < .001), and overall ease of use (4.7 vs. 2.6, p < .001). Residents rated single-use higher than reusable after each procedure in terms of ease of use (1.07 vs. 2.68, p < .001) and visual clarity (1.27 vs. 1.89, p = .003), while patients rated single-use higher for understanding of illness (3.9 vs. 3.1, p < .001) and understanding of treatment rationale (3.9 vs. 3.1, p < .001). Conclusion: Resident and patient experience feedback favored single-use rhinolaryngoscopes compared to reusable scope technology across multiple surveyed measurables. Single-use rhinolaryngoscopes provide a viable tool for otorhinolaryngologist and other clinicians to perform rhinolaryngoscopy consults. Level of Evidence: 4.
RESUMO
OBJECTIVE: Flexible endoscopic Zenker's diverticulotomy (FEZD) is a procedure performed primarily by gastroenterologists for treatment of symptomatic Zenker's diverticulum (ZD). Given the lack of prior investigations with large sample sizes, we report on one of the largest series of patients who underwent FEZD. METHODS: A review of patients who underwent FEZD at our institution from 2006 to 2021 was performed. Data were abstracted for patient demographics, clinical features, procedural characteristics, adverse events, and outcomes. RESULTS: A total of 75 patients (37 women) with mean age of 77.9 (33-102) years and mean (range) follow-up of 1.1 (0-13.2) years were identified. 67.9 % of FEZD cases were performed under general anesthesia. The mean procedure time was 37.1 min. Same day discharge and resumption of oral intake was seen in 56.4 % and 57.1 % of cases, respectively. Adverse events included intraprocedural bleeding (15.7 %) controlled with endoscopic means, infection (4.8 %) exclusively managed with antibiotics in all but one case, subcutaneous emphysema (2.4 %), and perforation (10.7 %) conservatively managed in all but one case. 97.6 % of patients had sustained subjective improvement in symptoms following their procedure. Fifteen patients (20 %) experienced recurrence after undergoing initial FEZD-26.7 % percent of whom were sufficiently treated with repeat FEZDs. Younger age was associated with recurrence (p < 0.01). CONCLUSION: FEZD is an effective, safe procedure for the management of symptomatic ZD. It is a viable alternative for patients in whom otorhinolaryngological procedures via rigid endoscopy are not an option.

OBJECTIVE: To compare the incidence of glottic stenosis in idiopathic subglottic stenosis (iSGS) patients with no prior surgical intervention to those with a history of endoscopic dilation and characterize the incidence of glottic involvement, changes in scar length, and progression of scar toward glottis following laser wedge excision (LWE). METHODS: A retrospective review of iSGS patients who underwent LWE between 2002 and 2021 was performed. Patients without prior airway surgery were labeled LWE primary (LWEP) and operative findings for LWEP patients were reviewed for glottic involvement, scar length (DL ), and distance from the glottis to superior-most aspect of scar (DGS ). Rates (in mm/procedure) of DΔL , reflecting an increase in length, and D-ΔGS , reflecting proximal migration, were calculated by dividing DΔL and D-ΔGS by the number of LWE procedures. RESULTS: 213 iSGS patients underwent LWE, with 132 being LWEP patients. LWEP had a lower incidence of baseline glottic involvement (n = 6, 4.5%) than LWE secondary (LWES; n = 6, 7.5%). Four new cases of glottic involvement were noted in LWEP patients following LWE, with only one being clinically significant resulting in permanently decreased vocal fold mobility. With each procedure, scar length increased by 1.0 mm and DGS decreased by 0.7 mm, reflecting a migration or decrease in DGS of 9.5% with each procedure with respect to initial DGS . Overall rates of glottic stenosis following operations were similar between LWEP and LWES cohorts, 7.6% and 7.5% respectively. CONCLUSION: There appears to be a low risk of glottic involvement resulting from the LWE procedure in iSGS patients. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:875-882, 2023.

OBJECTIVES: Endoscopic laser wedge excision (LWE) is an effective treatment option for idiopathic subglottic stenosis (iSGS); however, data regarding complications following LWE are limited. The aim of the following analysis was to provide a review of frequency and type of complications that occur with LWE in patients with iSGS. STUDY DESIGN: Retrospective review. METHODS: Patients with iSGS undergoing LWE between January 2002 and September 2021 were performed. Demographic data were recorded. Complications were stratified into major and minor categories. The frequency of these complications and the respective treatment for them was analyzed. RESULTS: 212 patients within the study period underwent a total of 573 LWE procedures. All but two patients were female, with a median age of 54 years at time of LWE. Of these patients, 43 (20 %) patients experienced a complication. Of these, only 7 (15 %) of the reported complications were considered major while the rest were minor in nature. Major complications included 3 cases of post-operative hemoptysis, 1 case of tracheitis, and 3 cases of reduced vocal fold hypomobility with concurrent glottic stenosis. Minor complications consisted of 2 cases of tooth fracture and 34 cases of tongue paresthesia post-operatively that was self-limited. There were no mortalities. CONCLUSION: Major complications occur in <5 % of LWE procedures based off the analysis. All major complications were managed without significant long-term morbidity. Minor complications with the LWE are self-limited in nature. Our data supports the LWE as a safe treatment option for iSGS.

Objectives: To examine the degree of agreement between MRI and histologically generated volumetric measurements of residual injection laryngoplasty material. Methods: Following left recurrent laryngeal nerve transection, rabbit vocal cords were injected with jellyfish collagen, Cymetra®, or Restylane®. Laryngeal tissue was harvested 4 or 12 weeks post injection followed by MRI imaging and histologic cross-sectioning. Two raters estimated the volume of remaining injection material in specimens within MRI and histologic axial cross sections. Wilcoxon signed rank tests were employed to detect gross differences between inter-rater measurements and between imaging modalities across time. Agreement between rater measurements and imaging (histology and MRI) was assessed using intra-class correlation coefficients. Results: Data was available from 16 rabbits sacrificed at 4 weeks (n = 8) and 12 weeks (n = 8). Inter-rater testing of MRI imaging revealed no significant differences (p > .05) between rater measurements across time points, and excellent agreement (0.93; 95% confidence interval 0.80-0.98) while histologically estimated volumes demonstrated a significant difference at 4 weeks (p < .05) and overall good agreement (0.89; 95% confidence interval 0.59-0.97). Comparison of MRI and histologically estimated volume measurements revealed significant differences at the 4-week time point (p < .05) but not at 12 weeks (p > .05). Overall, there is only moderate agreement between MRI and histology estimates (0.72; 95% confidence interval 0.22-0.90). Conclusions: MRI imaging demonstrates good reliability and similar estimates of volume to histologically estimated measurements of residual injection laryngoplasty material at time points clinically relevant for future injection laryngoplasty experiments. Level of Evidence: NA.
RESUMO
OBJECTIVE: While pedicled intranasal flaps, such as the nasoseptal flap (NSF), successfully reduce postoperative CSF leaks following endoscopic endonasal approaches (EEA) to the skull base, morbidity remains prevalent. This study describes the first cadaveric description and radiographic analysis of the posterior septal nasal floor mucosal flap (PSNF) designed to reduce pedicled nasal flap morbidity. A case series is also detailed. STUDY DESIGN: Cadaveric dissection, radiographic analysis, and case series. METHODS: Seven cadaver specimens underwent harvest of the PSNF. PSNF flap dimensions were measured on the thirty deidentified sinus computed tomography (CT) scans. A retrospective case series was performed on the first set of patients who received the PSNF for reconstruction of a sellar base defect. Information concerning complications, symptoms, and the appearance of the flap was recorded from records of the patient's postoperative inpatient stay, 1-week postop visit, and 1-month postop visit. RESULTS: Cadaver dissection of the PSNF flap demonstrated good arc rotation along its pedicle with ability to cover both sellar and planum defects. Cadaveric flap measurements and CT-derived measurements estimated a mean surface area of 16.7 and 18.3 cm2 , respectively. 15 patients underwent reconstruction of a sellar or planum defect using the PSNF technique. Only one CSF leak was encountered postoperatively. Minimal crusting of the flap and donor site was seen 1 month postoperatively. CONCLUSION: The PSNF flap provides a sizeable pedicled region for reconstruction comparable to other pedicled nasal flaps. Our case series demonstrated good postoperative outcomes without reduced donor site morbidity. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1561-1568, 2022.

OBJECTIVE: We present the outcomes for patients with idiopathic subglottic stenosis (iSGS) following their first carbon dioxide laser wedge excision (LWE) procedure, additionally examining the effect of compliance with adjuvant medical therapy (triple therapy) after the operation. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary center. METHODS: A retrospective review was performed on 183 patients with iSGS following their first LWE and their compliance to adjuvant medical therapy (inhaled corticosteroid, proton pump inhibitor, trimethoprim-sulfamethoxazole) following the operation, with all reviewed to December 31, 2020. The primary outcome variable was median time to recurrence (MTR). Patients were stratified by whether the LWE was their first operation (LWE primary or secondary), by compliance to triple therapy, and by compliance with trimethoprim-sulfamethoxazole. Kaplan-Meier analysis and Cox proportional hazards were used to evaluate the MTR across the stratifications. RESULTS: An overall 113 patients underwent their first LWE, while 70 received the procedure after having undergone 1 to 13 procedures. The MTR between LWE primary and secondary was 4.6 and 2.9 years, respectively. Adjusted Cox proportional hazards comparing these 2 groups revealed the number of prior operations to be a confounding variable. A statistically increased MTR was demonstrated with greater degrees of medical compliance. CONCLUSION: LWE conferred an MTR of 4.1 years in the iSGS cohort. The number of prior procedures preceding LWE behaved as a confounding variable. Patients who were completely or partially compliant to triple therapy appear to demonstrate increased intervals prior to recurrence.

Objective To evaluate the short- and long-term effects of tricyclic antidepressants (TCAs) and gabapentin in the treatment of unexplained chronic cough (UCC). Study Design Prospective cohort. Setting Tertiary care hospital. Subjects and Methods Patients seen between July 2016 and March 2017 were included following a formal workup and clinical evaluation indicative of UCC. Patients were placed on either a TCA (amitriptyline or nortriptyline) or gabapentin. Leicester Cough Questionnaire (LCQ) and percentage improvement scores were obtained prior to treatment initiation and at 2 and 6 months of neuromodulator treatment. A linear mixed model assessed the change in LCQ score between the 2 treatment time points and baseline scores. Results Twenty-eight patients completed a total of 37 neuromodulator trials. Gabapentin demonstrated statistically significant improvement in LCQ scores at 2 months (2.48 points, P≤ .01) and 6 months (5.40 points, P = .01) of treatment as compared with baseline. Patients taking TCAs demonstrated statistically significant improvement of LCQ scores at 2 months of treatment (3.46 points, P≤ .01). However, the majority of patients discontinued treatment, most commonly secondary to the development of tachyphylaxis after 2 months, precluding analysis at 6 months. Conclusion While both neuromodulator classes demonstrated short-term benefit, the majority of patients discontinue treatment prior to 6 months, with patients taking TCAs discontinuing more frequently than patients on gabapentin. Future investigations are warranted evaluating tachyphylaxis and the utility of dual treatment therapies designed to address peripheral and central sensory pathways involved in UCC.

Objective To describe the profile and outcomes of elderly patients undergoing medialization laryngoplasty for vocal cord paralysis. Study Design Case series with retrospective review. Setting Tertiary care hospital. Subjects and Methods Patients were included in the study if they were >65 years old at the time of medialization laryngoplasty between 2008 and 2015. Patient comorbidities, anticoagulation status, disease etiology, and physical examination findings were recorded with postoperative length of stay, complications, pre- and posttreatment voice outcomes with the Voice Handicap Index (at 6 weeks, 4 months, 8 months, and 1 year), and postprocedural interventions (revision injections, surgery, therapy). Results A total of 112 patients met the eligibility criteria. Iatrogenic injury to the recurrent laryngeal nerve (50%) was the most common etiology, followed by idiopathic (31%) causes. Sixty percent of patients were receiving long-term antiplatelet and/or anticoagulation therapy. All but 14 patients on aspirin therapy stopped their antiplatelet/anticoagulation therapy prior to surgery. Most patients were discharged on the day of surgery. Postprocedure Voice Handicap Index scores significantly improved ( P < .001) by 47%, 53%, 64%, and 57% at each of the 4 measured postprocedure dates, respectively. Two patients had major nonsurgical complications postoperatively requiring inpatient hospitalization. Chi-square analysis revealed no differences between intraoperative aspirin use, sex, or comorbidities and the incidence of complications ( P > .05). Conclusion The clinical profile and outcomes of our patients undergoing medialization laryngoplasty are comparable to those seen in younger cohorts. Medialization laryngoplasty is a safe and successful option for elderly patients with vocal cord paralysis and vocal handicap.

PURPOSE: Nerve repair after a segmental defect injury remains a challenge for surgeons. Fibrin glue can be used to expedite surgical procedures and maintain proper nerve spatial orientation to potentially optimize recovery, yet surgeons hesitate to use it owing to concerns about fibrin's inhibiting regeneration and increasing scar formation. The purpose of these experiments was to evaluate whether fibrin glue impedes nerve regeneration. METHODS: A critical-size defect of 10 mm was created in 32 Sprague-Dawley rats with 4 different forms of repair: a collagen type-I conduit (n = 8), a collagen type-I conduit filled with fibrin glue (n = 8), an autologous nerve graft (n=8), and an autologous nerve graft with fibrin glue (n = 8). Behavioral tests, including sciatic functional indices, were used to evaluate functional recovery. Neurophysiology, immunohistochemistry, and nerve morphometry were used to critically analyze nerve regeneration. RESULTS: Multiple outcome parameters for nerve regeneration, remyelination, behavior, and electrophysiology were used to determine that the addition of fibrin did not influence recovery for the autograft groups. Similarly, within the conduit group, behavioral tests showed comparable functional recovery and indistinguishable results in compound motor action potential and nerve morphometry. Immunohistochemistry revealed identical degrees of Wallerian degeneration and scarring between conduit groups. CONCLUSIONS: The addition of fibrin to either the conduit or the autograft group did not result in any meaningful differences in recovery. Our data demonstrate that fibrin glue does not impede nerve regeneration or functional recovery after surgical repair of a segmental nerve defect in a rat model. CLINICAL RELEVANCE: The clinical use of fibrin glue as an adjunct with peripheral nerve repair may be considered safe because it does not impair nerve regeneration with critical size defects in an animal model.
