BACKGROUND Metformin use has been linked to improved cancer outcomes. The purpose of this study was to determine the impact of metformin on the survival of patients with laryngeal cancer. METHODS We retrospectively reviewed 205 patients with a diagnosis of laryngeal squamous cell carcinoma (SCC). RESULTS Patients taking metformin presented with more(More)
Globus sensation (GS) is a common benign finding that is often associated with frequent throat clearing and is commonly a result of laryngopharyngeal reflux. The primary objective of this investigation was to examine the role of the modified barium swallow study (MBSS) with esophagram in the diagnosis and management patients who present with chief(More)
BACKGROUND Sentinel lymph node biopsy remains controversial for cutaneous melanoma of the head and neck (CMHN). Incidence and factors associated with recurrence after negative sentinel lymph node biopsy have not been well delineated. METHODS Characteristics of 204 patients with head and neck melanoma who had a negative sentinel lymph node biopsy were(More)
Importance Transoral robotic surgery (TORS) is increasingly employed as a treatment option for squamous cell carcinoma of the oropharynx (OPSCC). Measures of surgical learning curves are needed particularly as clinical trials using this technology continue to evolve. Objective To assess learning curves for the oncologic TORS surgeon and to identify the(More)
OBJECTIVE The aim in this paper was to determine risk factors for the development of a postoperative CSF leak after an endoscopic endonasal approach (EEA) for resection of skull base tumors. METHODS A retrospective review of patients who underwent EEA for the resection of intradural pathology between January 1997 and June 2012 was performed. Basic(More)
BACKGROUND Laryngeal framework surgery (LFS) remains a cornerstone treatment in the management of glottic insufficiency. Traditionally, a history of radiation to the neck has been considered a relative contraindication to LFS. METHODS A retrospective matched cohort study was performed to study LFS outcomes in patients with and without a history of(More)
After a control period on a placebo, 45 patients with mild to moderate hypertension were treated with metoprolol, 100 mg twice daily alone and in free combination with chlorthalidone 50 mg daily using a double-blind crossover technique. The beta-blocker alone induced a significant fall in blood pressure; the diastolic pressure was reduced to 100 mg Hg or(More)
The differential diagnosis for clear cell neoplasms of the sinonasal tract is wide but critical to understand. In this paper, we describe a case of renal cell-like adenocarcinoma (SNRCLA) presenting as a paranasal sinus mass with clear cell morphology. The relevant literature is reviewed and the workup for clear cell neoplasms described. SNRCLA is a rarely(More)
From 18% to 35% of cutaneous melanomas are located in the head and neck, and nearly 70% are thin (Breslow thickness ≤ 1 mm). Sentinel lymph node biopsy (SLNB) has an established role in staging of intermediate-thickness melanomas, however its use in thin melanomas remains controversial. In this article, we review the literature regarding risk factors for(More)
OBJECTIVE To describe the clinical presentation and role of the otolaryngologist in the evaluation of eosinophilic esophagitis (EoE) at a tertiary pediatric hospital. STUDY DESIGN Retrospective review. METHODS Records from pediatric patients with a diagnosis of EoE from 2003 to 2015 were reviewed. Study variables were analyzed to compare patients(More)
