ABSTRACTObjectiveWhile endoscopic laser wedge excision (LWE) for iSGS demonstrated lower surgical recurrence rates compared to endoscopic dilation (ED), ED remains the primary technique employed. Additionally, serial intralesional steroid injections (SILSIs) also demonstrate benefits in controlling disease. We aimed to compare surgical recurrence rates following ED, ED + SILSI, and LWE following a patient's first operation.MethodsThis was a two‐center retrospective analysis of iSGS patients who underwent either ED, ED + SILSI, or LWE. Patients were followed to their last follow‐up date or reoperation. Kaplan–Meier analysis and Cox proportional hazards were used to evaluate the recurrence times across the different surgical groups with additional stratification by age, compliance to medical adjuvant therapy, and percentage of stenosis rated at reoperation.ResultsA total of 126 patients from Institution 1 underwent LWE, while at Institution 2, ED and ED + SILSI were performed on 32 and 23 patients, respectively. One‐year recurrence estimates were 9%, 53%, and 0% for LWE, ED, and ED + SILSI, respectively, while 5‐year recurrence estimates were 45%, 90%, and 19%, respectively. Adjusted Cox‐proportional hazard ratios demonstrated a greater risk of surgical recurrence with ED compared to LWE (2.25; 95% confidence interval [CI]: 1.31–3.88) and no difference between ED + SILSI and LWE (0.84; 95% CI: 0.32–2.25).ConclusionLWE demonstrates reduced recurrence times compared to ED when controlling for surgery number, age, triple therapy compliance, and percentage of stenosis at reoperation. The application of postoperative SILSI appears to similarly reduce recurrence rates comparable to LWE and warrants further investigation.

AbstractObjectiveThis study aims to evaluate the impact of parity on the severity and recurrence rates of idiopathic subglottic stenosis (iSGS) in premenopausal females.Study DesignA retrospective cohort study.SettingTwo tertiary care centers from 2002 to 2024.MethodsWe analyzed premenopausal iSGS patients under 40 years who underwent balloon dilation or laser wedge excision. Clinical features, including demographics and pregnancy history, were examined. Recurrence rates between nulliparous and parous patients were compared using Poisson regression, adjusting for age and follow‐up duration. Linear regression assessed the relationship between pregnancy and iSGS recurrence.ResultsForty‐eight patients were included, with 36 parous and 12 nulliparous. Adjusting for age and follow‐up, the mean recurrence rate was 2.6 times higher in parous patients (95% confidence interval [CI]: [1.5, 4.8], P = .0008). Each additional pregnancy was associated with 0.81 additional recurrences (95% CI: [0.05, 1.57], P = .0375). No significant differences in surgery‐free time were observed between groups.ConclusionParity and pregnancy significantly increase the risk of iSGS recurrence, although they do not accelerate subsequent recurrences. Health care providers should counsel women of childbearing age about these risks in family planning discussions, emphasizing shared decision‐making regarding potential surgical interventions.Level of evidence3.

AbstractPurposeThe small and complex space of the intranasal cavity poses a challenge to teaching and learning sinonasal anatomy in undergraduate medical education. Evidence suggests that utilizing 3D‐printed (3DP) models is an effective means to comprehend anatomical structures and their spatial relationships. In this study, we introduce and evaluate the educational value of rigid nasal endoscopy on realistic 3DP and silicone‐cast sinus models as a method to teach medical students intranasal anatomy.MethodsTwelve first‐year medical students participated in an educational rigid‐nasal endoscopy workshop led by Otolaryngology PGY‐2 residents and rhinology consultants. The workshop consisted of (1) an introductory PowerPoint on rigid nasal endoscopy and basic intranasal anatomy, (2) timed trials that tested students' ability to locate intranasal anatomical structures while scoping with a rigid endoscope, and (3) pre‐ and post‐surveys.ResultsParticipants improved in their ability to locate each intranasal anatomical structure during the timed trials. Participants felt that rigid endoscopy of 3DP models was an effective method to learn intranasal anatomy compared to their traditional medical school anatomy course.ConclusionThe results of this study suggest that rigid nasal endoscopy of 3DP sinus models is a potentially high‐value educational method for teaching intranasal anatomy to first‐year medical students. Students enjoyed the opportunity to learn intranasal anatomy while practicing a clinically relevant procedure ‐ rigid nasal endoscopy.

Objective(s): To quantify and compare pre-procedure worry versus the experience of pain, gagging, and dyspnea during in-office laryngoscopy procedures in patients who did or did not receive pre-procedure anxiolytics, and to explore patient perception of intra-procedure interventions. Methods: Patients undergoing awake laryngology procedures at a quaternary care center were enrolled. The State-Trait Anxiety Inventory (STAI) Y1 and Y2 questionnaires were administered to establish baseline levels of state anxiety and trait anxiety, respectively. Pre-procedure and post-procedure surveys assessed patient perception of select interventions. Results: 34 patients were enrolled (35.3% female, 91.2% white, mean age 60 years). Pre-procedure, 51.5% of patients reported some degree of worry about pain, 61.8% about gagging, 52.9% about dyspnea, and 55.9% about having something in their nose/throat. Post-procedure, 54.5% reported experiencing pain to some degree, 63.6% had gagging, 39.4% had dyspnea, and 78.7% were bothered by having something in their nose/throat. Patients who received a pre-procedure anxiolytic were significantly more likely to report more pain compared to those who did not. The highest rated interventions were pre-procedural education (97.0% “Very helpful”), verbal reassurance (96.9%), provider communicating steps of the procedure (96.9%), and reminders to breathe (87.5%). Conclusion: For patients undergoing awake laryngology procedures, the anticipation of gagging, pain, trouble breathing, and scope-related discomfort are worrisome factors. Of these, scope-related discomfort and gagging are the most often-reported sources of intraprocedural discomfort. The interventions patients found most helpful were based on preprocedural education and clear intraprocedural communication, which suggests that purposeful communication has a role in relieving anxiety.

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

ObjectiveTo identify characteristics of patients who have poor improvement in symptoms following surgical management of Zenker Diverticulum (ZD).MethodsProspective, multicenter cohort study of all individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative who underwent surgical repair of ZD between August 2017 and January 2024. Patient demographics, esophagrams, and the 10‐item Eating Assessment Tool (EAT‐10) pre‐ and post‐procedure were obtained from a REDCap database. t‐tests, Wilcoxon rank sum tests, Chi‐square or Fisher's exact tests were used to compare the characteristics. Patients with <50% improvement in their EAT‐10 scores were deemed surgical nonresponders (SNRs). Those with ≥50% improvement in their EAT‐10 scores were deemed surgical responders (SRs).ResultsA total of 184 patients were prospectively followed after undergoing either open or endoscopic surgical management. Twenty‐two patients (12%) were deemed SNRs. Preoperative presence of a hiatal hernia was statistically significant characteristic between the SNRs (63.6%) and SRs (32.1%) (p = 0.004). Size of the ZD and history of previous ZD surgery was not a significant characteristic. The length of stay and complication rate were not statistically different between the groups.ConclusionCoexistent esophageal pathology may lead to poor symptomatic improvement following ZD surgery. Preoperative workup of other esophageal disorders is recommended to detect likely SNRs. For SNRs, further esophageal workup may be necessary to evaluate for other esophageal causes related to poor symptomatic improvement following ZD surgery.Level of Evidence3 Laryngoscope, 134:4897–4902, 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.
