ObjectiveTo describe and compare rates of metachronous and synchronous second primaries of the contralateral tonsil in patients with primary HPV(+) tonsillar squamous cell carcinoma (SCC).Study DesignRetrospective cohort study.Materials and MethodsThis is a single tertiary care center retrospective case series, from 2006 to 2019, of HPV(+) tonsillar SCC patients who underwent primary surgical resection with unilateral wide‐field tonsillectomy or bilateral tonsillectomy for diagnostic or therapeutic purposes. A metachronous second primary is one diagnosed >6 months after completion of surgical treatment. A synchronous second primary is one diagnosed during bilateral tonsillectomy for unilateral HPV(+) tonsillar SCC. Rates of second primary and patient characteristics were compared using chi‐square tests.ResultsAbout 303 patients underwent unilateral surgical resection +/− adjuvant therapy for HPV(+) tonsillar SCC. One (0.3%) developed a metachronous second primary in the contralateral tonsil 11.9 years following treatment. Fifty‐seven patients with HPV(+) tonsillar SCC underwent bilateral tonsillectomy, and 37/57 (65%) had no clinical signs for contralateral disease. Of these, only 1/37 (2.7%) was incidentally found to have a synchronous second primary. Twenty patients underwent bilateral tonsillectomy due to clinical concern for contralateral disease. Of these, 3/20 (15%) were found to have a synchronous HPV(+) SCC in the contralateral tonsil.ConclusionsThe prevalence of metachronous second primary after appropriate treatment of HPV(+) tonsillar SCC is very low (0.3%) and so is the chance of incidentally discovering a synchronous second primary during bilateral tonsillectomy (2.7%). We do not recommend bilateral tonsillectomy as a part of the routine algorithm in the surgical management of these patients.Level of Evidence3 Laryngoscope, 132:332–338, 2022

Objective: Transoral endoscopic laser-assisted diverticulotomy (TELD) with diverticulectomy and diverticuloplasty (TELD + DD) for the management of Zenker’s diverticulum (ZD) has been utilized by our institution since 2016 in attempts to reduce residual pouch size. This technique involves complete endoscopic pouch excision with partial advancement of mucosal flaps. Our study compares the subjective outcomes, objective outcomes, and complication rates between TELD and TELD + DD. Methods: A retrospective cohort study was performed on patients who underwent TELD or TELD + DD by a single surgeon at a tertiary academic center (2013-2019). Videofluoroscopic swallow studies (VFSS) with esophagram, Eating Assessment Tool (EAT-10), Reflux Symptom Index (RSI), and Functional Outcome Swallowing Scale (FOSS) were collected at preoperative and 3 month follow-up visits. A single blinded reviewer recorded height, width, and depth of pre and postoperative pouches with volumetric analysis performed assuming an ellipsoid shape. Comorbidities, complications, postoperative course, and recurrence were recorded. Results: Of the 75 patients that met criteria, 27 underwent TELD + DD and 48 underwent TELD. Eighteen TELD + DD and 37 TELD had both pre and post-operative VFSS. TELD + DD and TELD had a 96 ± 7% and 87 ± 16% reduction in pouch volume, respectively ( t-test; P = .01). Complications (TELD + DD 7%, TELD 17%, fisher’s exact; P = .31) and final subjective outcomes after adjusting for initial were not significantly different between methods (EAT-10 with TELD + DD ∆ + 1.3, P = .18; RSI ∆ + 1.4, P = .29; FOSS ∆-0.02, P = .91). One short-term recurrence was reported with TELD. Conclusion: Use of TELD + DD is associated with a statistically significantly decreased residual pouch size with no significant difference in short-term subjective outcomes. Complication rates and short-term recurrence rates are comparable. Long-term recurrence rates will require further studies to characterize. Level of Evidence: Level 3.

ObjectiveInclusion body myositis (IBM) is a progressive inflammatory myopathy with dysphagia as a debilitating sequalae. Otolaryngologists are consulted for surgical candidacy when there are findings of cricopharyngeal dysfunction. We aim to compare transcervical cricopharyngeal myotomy (TCPM) versus endoscopic cricopharyngeal myotomy (ECPM) in the IBM population with particular focus on objective swallow study outcomes, complications, and recurrence rates.MethodsA retrospective cohort study was performed on IBM patients who underwent TCPM or ECPM (1981–2020) in the Department of Otolaryngology at a tertiary academic center with a high volume IBM referral base. Videofluoroscopic swallow studies, Eating Assessment Tool (EAT‐10), Reflux Symptom Index (RSI), and Functional Outcome Swallowing Scale (FOSS) were collected at preoperative and follow‐up visits. Baseline patient characteristics, intraoperative data, and postoperative course were recorded.ResultsForty‐one patients were identified (18 TCPM; 23 ECPM). There was no significant difference in the recurrence rates, complications, hospitalization length, operative time, or return to preoperative diet between approaches. For the 12 patients (11 ECPM; 1 TCPM) that had subjective swallow data, there was a statistically significant difference in the pre and postoperative scores for EAT‐10, RSI, and FOSS (P < .05). There was a statistically significant improvement in the degree of narrowing between pre and postoperative imaging for both approaches (P < .05).ConclusionBoth TCPM and ECPM are safe approaches for the management of dysphagia in patients with IBM with objective evidence of cricopharyngeal dysfunction. Cricopharyngeal myotomy is a durable technique that has demonstrated improved subjective and objective outcomes in this patient population.Level of Evidence3 Laryngoscope, 131:E2426–E2431, 2021
