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

ObjectivesThe spine is the most common site of bone metastases in differentiated thyroid cancer (DTC). The role of surgery in the management of cervical spine (C‐spine) metastases (CSpM) has not been adequately explored.MethodsThis is a retrospective cohort study at a tertiary referral center from 2002 to 2018. Inclusion criteria were pathologic diagnosis of DTC and imaging/pathologic diagnosis of CSpM. Statistical analysis utilized t tests for continuous variables and χ2 tests for categorical variables. Survival analysis was conducted using Kaplan–Meier curves with univariate and multivariate Cox regressions.ResultsFifty patients with DTC and CSpM were identified. Of those, 16 underwent surgical resection of the C‐spine, whereas 34 did not. The most common presenting symptom was neck pain (N = 37, 74%). Patients in the surgery group were more likely to report a subjective improvement of symptoms (P < .01) and to have local (P < .01) and systemic (P = .04) disease control. Five‐year overall survival was 44.7% for the surgery group (95% confidence interval [CI]: 17.1–69.3) and 11.1% (95% CI: 2.1–28.8) for the nonsurgery group (P = .01). The strongest risk factor for improved overall survival after C‐spine metastasis was local disease control at the C‐spine (multivariate hazard ratio [HR] = 0.32, 95% CI: 0.12–0.85, P = .02). Surgical intervention was significantly associated with improved survival on both univariate (HR = 0. 35, 95% CI: 0.15–0.82, P = .02) and multivariate (HR = 0.37, 95% CI: 0.14–0.98, P = .04) analysis.ConclusionSurgical management of CSpM in differentiated thyroid cancers is associated with significantly improved local disease control and overall survival. Referral to spine surgeons should be considered after diagnosis.Level of EvidenceIV. Laryngoscope, 131:E1741–E1747, 2021

Radioiodine ablation is a commonly utilized treatment for differentiated thyroid carcinoma. Uptake of radioiodine can be enhanced by pretreatment with thyroid hormone withdrawal or administration of recombinant human thyroid‐stimulating hormone (rhTSH). rhTSH is generally well‐tolerated with minimal adverse effects. However, in patients with extensive tumor burden in confined anatomic spaces, rapid enlargement of normal or neoplastic thyroid tissue secondary to rhTSH administration can result in significant compressive effects. In this report, we describe a case of rapid airway deterioration requiring intubation in a patient with involvement of the thyroid cartilage by papillary thyroid carcinoma.Laryngoscope, 122:0000–0000, 2019 Laryngoscope, 130:2725–2727, 2020
