OBJECTIVE The effortful swallow was designed to improve posterior mobility of the tongue base and increase intraoral pressures. We characterized the effects of this maneuver via dynamic magnetic resonance imaging (dMRI) in healthy patients. METHODS A 3-T scanner was used to obtain dMRI images of patients swallowing pudding using normal as well as(More)
OBJECTIVES/HYPOTHESIS Indications for antiplatelet and anticoagulation use are expanding. There is no evidence to direct therapeutic management in patients undergoing microlaryngeal surgeries. Our aim was to compare bleeding complications between microlaryngeal surgeries performed for patients preoperatively taken off and maintained on antiplatelet and/or(More)
OBJECTIVES/HYPOTHESIS Melanin is a pigmented polymer with a known role in dermal solar protection. In vertebrates, melanogenesis has been reported in leukocyte populations, suggesting a potential role in innate immunity. In this study, we report the novel finding of melanin associated with chronic inflammation and speculate on its potential role in the(More)
OBJECTIVES/HYPOTHESIS To provide insight into the demographics and vocal habits of current Broadway musical theater performers. STUDY DESIGN Prospective, Questionnaire. METHODS Adult musical theater performers in Broadway Productions as defined by the League of American Theater Producers and the Actors' Equity Association were asked to complete a survey(More)
OBJECTIVES/HYPOTHESIS The purpose of this study is to describe an endoscope-assisted surgical technique for the excision of branchial cleft cysts and compare it to the standard approach. STUDY DESIGN Retrospective case series review. METHODS Twenty-seven cases described as branchial cleft excisions performed by a single surgeon at one academic medical(More)
OBJECTIVES/HYPOTHESIS Given that the vocal folds are active organs of respiration, reports of dyspnea in the context of glottic insufficiency are not uncommon. We hypothesize that improved glottal closure via framework surgery or vocal fold augmentation improves dyspnea symptoms. STUDY DESIGN Retrospective review. METHODS Charts of patients undergoing(More)
The human vocal folds are complex structures made up of distinct layers that vary in cellular and extracellular composition. The mechanical properties of vocal fold tissue are fundamental to the study of both the acoustics and biomechanics of voice production. To date, quantitative methods have been applied to characterize the vocal fold tissue in both(More)
