AbstractObjectiveTo compare reflux symptoms, Zenker's diverticulum recurrence, and clinical outcomes in patients with and without a history of hiatal hernia who underwent Zenker's diverticulotomy (ZD).Study DesignSingle institution retrospective review.SettingTertiary care academic hospital.MethodsA retrospective review of patients with and without a history of hiatal hernia who underwent ZD via an open stapler, rigid endoscopic CO2 laser, stapler, or harmonic scalpel technique from January 2006 to December 2020 was performed. Data were abstracted for patient demographics, reflux symptoms, and rates of adverse events and symptomatic recurrence.ResultsA total of 426 patients were included in the study, 97 (22.8%) of which had a history of hiatal hernia. Eleven patients (11.3%) with a history of hiatal hernia had undergone Nissen fundoplication prior to ZD. Patients with a history of hiatal hernia showed less symptomatic improvement postoperatively. Significant differences were noted in the change in the Eating Assessment Tool (EAT‐10) (P < .01) and Reflux Symptom Index (RSI) (P = .03) where patients without a history of hiatal hernia improved more than hiatal hernia patients. Despite these differences in symptom relief, rates of postoperative complications and rates of recurrence did not significantly differ between groups. The median time to recurrence was similar for both groups.ConclusionPatients without a history of hiatal hernia had significantly larger improvements in EAT‐10 and RSI scores compared to patients with a history of hiatal hernia. However, these differences in scores may not represent clinically meaningful differences. There were no significant differences in postoperative adverse events or in recurrence of the Zenker's diverticulum between groups.

ObjectiveTo evaluate the impact of age on disease recurrence in idiopathic subglottic stenosis (iSGS) patients.MethodsThis was a retrospective chart review of iSGS patients treated with laser wedge excision. Patients did not have prior surgery. Survival rates free of recurrence were estimated using the Kaplan–Meier methods, and associations were evaluated using Cox Proportional Hazards models.ResultsEighty‐five female patients were included in the study. Most patients (68%) were postmenopausal, had first period at or before 13 years of age, had at least one full‐term pregnancy (82%), were not undergoing hormone replacement therapy (93%), were not using hormonal birth control (88%), and were either partially or completely compliant with triple therapy regime (80%). There was a statistically significant average reduction in risk of recurrence of 5% for every additional year of age (p < 0.0001). When compared to patients older than 65 years of age, patients less than 35 were nearly 10 times more likely to recur (p = 0.002), and patients 55–65 and 45–55 years of age were 8 and 5 times more likely to recur, respectively (p = 0.003 and 0.009). Additionally, females on birth control showed decreased risk of recurrence of 74% compared with their counterparts (p = 0.04).ConclusionThis is the first study to demonstrate an inverse relationship between age and disease recurrence in patients with iSGS following surgery. Using age as a surrogate for menopausal status, these results suggest that increased age and/or birth control provide a protective effect through decreased recurrence rates, possibly mediated by decreased estrogen levels.Level of Evidence4 Laryngoscope, 2024

ObjectiveTo evaluate the impact of methotrexate and rituximab therapy on highly recurrent idiopathic subglottic stenosis (iSGS) patients with a negative antineutrophil cytoplasmic antibody titer cANCA(−).MethodsThis was a retrospective cohort study of highly recurrent iSGS patients who recurred within 1 year or less and were treated with methotrexate (MTX), and rituximab (RTX), or a combination of both at different time points (MTX/RTX). Average surgical durations before and after drug treatment were summarized, and the differences were calculated.ResultsA total of 21 female patients with median age of 62 years were included. Fifteen patients were treated with MTX, three were treated with RTX, and five treated with both. Patients treated with immunosuppressants showed a trend toward longer intervals between operations (mean pre‐drug interval: 338; mean post‐drug interval: 697 days) (p‐value = 0.25). Three patients did not recur following drug initiation with median follow‐up of 1265 days. All three treatment groups demonstrated a trend toward increased post‐drug recurrence intervals (MTX: 444 days, RTX: 374 days, MTX/RTX: 55 days), that was not statistically significant. Patients with prior dilations demonstrated longer post‐drug recurrence intervals (mean pre‐drug interval: 341 days, mean post‐drug interval 978 days) (p‐value = 0.17). Four patients in the cohort with the highest recurring disease improved from mean 129 days between operations to 509 days with drug therapy. The most common drug side effect was nausea (16%).ConclusionMTX and RTX may be treatment options for some highly recurrent iSGS patients. Initial results are variable and demonstrate a need for further research on drug candidacy.Level of Evidence3 Laryngoscope, 2024

AbstractObjectiveAnalyze the duration of symptom‐free intervals following laser wedge excision (LWE) for recurrent idiopathic subglottic stenosis (iSGS). Secondary aim includes evaluating the influence of patient‐related or disease factors.Study DesignRetrospective review.SettingTertiary center.MethodsReview of iSGS patients who underwent LWE between 2002 and 2021. LWE patients without prior airway surgery were labeled LWE primary (LWEP) and those with prior history of dilation were labeled LWE secondary (LWES). A conditional frailty repeated events model was used to analyze the median time to recurrence (MTR) for each nth recurrence. Secondary analysis included stratification by use of medical therapy and initial preoperative characteristics of scar (Myer‐Cotton grade, distance between the glottis and superior‐most aspect of scar, DGS; length of scar, DL).ResultsTwo hundred and ten iSGS patients underwent LWE (131 LWEP, 79 LWES). The proportion of patients experiencing at least 1, 3, 6, and 12 recurrences, respectively, was 68.0% (n = 143), 40.7% (n = 85), 20.0% (n = 42), and 5.2% (n = 11). There was exponential time‐shortening from the 1st to 12th recurrence (P < .0001). While MTR was 4.1 years after the first LWE, this fell to 2.8, 1.7, 1.0, and 0.7 years for the 2nd, 3rd, 6th, and 12th recurrences. Furthermore, LWEP patients experienced longer MTR than LWES counterparts within the first 6 recurrences (P < .01). There was no significant relationship between intersurgical interval and medication adherence, DL, DGS, or grade for recurrences beyond the first (P = .207, P = .20, P = .43, P = .16).ConclusionSymptom‐free intervals in iSGS shorten with each subsequent recurrence and LWE. The difference in MTR between LWEP and LWES groups was significant within the first 6 recurrences with LWEP having longer MTR.Level of Evidence3.

Background: Objective measurement of where observers direct their attention to faces when searching for signs of facial plastic surgery (FPS) is currently lacking. Objective: To compare where laypersons direct their attention on facial photographs using eye-tracking software when they are asked to (1) search for signs of aesthetic facial surgery or (2) allowed to gaze without direction (free-gaze). Methods: Naïve observers either free-gazed or examined faces for signs of FPS (FPS-prompted) for 10 s per face while their gaze was recorded by an eye-tracking system. Faces had no known history or signs/stigmata of FPS and were selected from the FACES and CFD databases with a diverse demographic distribution. Gaze times in nine facial subregions were analyzed using mixed-effects linear regression. Results: In FPS-prompted observers ( n = 50, mean age 32.7 ± 11.3 years, 23/50 (46%) female), the nose, mouth, cheeks, and forehead experienced the most substantial increases ( p < 0.001) and a high percentage of overall gaze time (17.9%, 12.5%, 12.0%, 9.6%, respectively) compared to free-gazing observers [ n = 57, 35.5 ± 13.9 years, 31/57 (54%) female]. Conclusions: Observers direct attention differently on a face when searching for signs of plastic surgery with increased attention on the nose, mouth, cheeks, and forehead.

AbstractObjectiveTo report on a series of patients with cANCA/PR3‐positive, granulomatosis with polyangiitis (GPA)‐associated subglottic stenosis (SGS) and evaluate response to medical maintenance therapy with rituximab versus other immunosuppressants following initial endoscopic laser excision.Study DesignRetrospective chart review.SettingTertiary academic center.MethodsA retrospective chart review of patients with SGS and cANCA/PR3‐positive GPA who received immunosuppressive maintenance therapy following endoscopic laser excision at our institution from June 1989 to March 2020 was performed. Data pertaining to patient demographics, clinical features, medications, and endoscopic laser procedures were collected.ResultsA total of 27 patients (15 women) with mean age (range) of 40 (19‐59) years and mean (range) follow‐up of 12.6 years (1.5‐28.6) were identified. Sixteen patients (60%) had limited GPA. Six patients (24%) had previously received local intervention with open surgery (n = 1, 4%) or endoscopic techniques (n = 5, 20%). All patients experienced symptom improvement following initial CO2 laser excision at our institution without any procedural complications or adverse events. Following initial laser excision, 15 patients (60%) were treated with rituximab and 10 patients (40%) were treated with nonrituximab immunosuppressive agents. Patients treated with rituximab were less likely to recur (P = 0.040). Limited GPA was associated with an increased incidence of recurrence (P = 0.031). Median time (years) to recurrence (range) was 3.2 (0.3‐19.3) and was not significantly associated with treatment or GPA subtype.ConclusionEndoscopic CO2 laser excision is a safe and effective local intervention for GPA‐associated SGS. Medical maintenance therapy with rituximab reduces risk of recurrence following initial laser excision relative to treatment with non‐rituximab agents.

AbstractObjectivesSingle‐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.MethodsEighteen 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.ResultsSingle‐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).ConclusionResident 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 Evidence4.

Background Septoplasty is used to correct nasal obstruction from nasal septum deviation. However, the long‐term efficacy of septoplasty is unclear, and no literature reviews have examined long‐term outcomes of septoplasty with or without turbinate modification. This systematic review aimed to evaluate the long‐term efficacy of septoplasty with or without turbinate modification in improving nasal obstruction. Data Sources PubMed, EMBASE, Cochrane CENTRAL. Methods A systematic review of the literature was conducted using the aforementioned databases. Studies reporting outcomes 12+ months after functional septoplasty with or without turbinate surgery for nasal obstruction were included. Septorhinoplasties, concurrent sinus surgery, pediatric studies, and studies where septoplasty was performed for indications other than nasal obstruction were excluded. Results After screening, 35 studies with 4,432 patients were included. Mean weighted post‐operative follow‐up time was 29.1 months (range 12–120 months). All studies reported significant improvement in subjective and objective outcomes at long‐term follow‐up compared to baseline. When comparing short‐term (<12 months) to long‐term (≥12 months) outcomes, four studies noticed that subjective outcomes worsened slightly over time, but no study found a significant change in objective outcomes over time. In addition, 23 studies reported patient satisfaction and/or improvement rates, with 75.4% (2,348/3,113) of patients expressing satisfaction/improvement at an average of 27.0 months after surgery. Conclusions Overall, septoplasty with or without turbinate modification shows significant improvement in obstructive symptoms at long‐term follow‐up per both objective and subjective measures. Whether outcomes may worsen slightly over time remains indeterminate based on mixed results in the literature. Level of Evidence N/A Laryngoscope , 134:2525–2537, 2024
