Prevalence of Vocal Fold Pathologies Among First‐Year Singing Students Across Genres
Objectives/Hypothesis The purpose of the study was to compare the prevalence of vocal fold pathologies among first‐year singing students from the classical, musical theatre, and contemporary commercial music (CCM) genres. Study Design Prospective cohort study. Methods Videostroboscopic examinations were rated by blinded expert raters. Vocal pathology was defined as a vocal fold abnormality on the membranous or cartilaginous portions of the vocal folds or hypomobility. Consensus among...

Effect of vocal fold implant placement on depth of vibration and vocal output
Objective Most type 1 thyroplasty implants and some common injectable materials are mechanically stiff. Placing them close to the supple vocal fold mucosa can potentially dampen vibration and adversely impact phonation, yet this effect has not been systematically investigated. This study aims to examine the effect of implant depth on vocal fold vibration and vocal output. Study Design Computational simulation. Methods Voice production was simulated with a fiber‐gel finite element computational...

Adult ambulatory otologic surgery: Unplanned revisits and complications
Objectives Determine rates and reasons for unplanned revisits after ambulatory otologic surgery. Methods Cross‐sectional analysis of State Ambulatory Surgery Databases of California, Florida, Iowa, and New York was performed for years 2010 and 2011. Ambulatory adult otology surgical procedures were linked to ambulatory, emergency, and inpatient databases for revisit encounters occurring within 30 days. The numbers of revisits and associated diagnoses were analyzed. Results A total of...

Increased expression of estrogen receptor beta in idiopathic progressive subglottic stenosis
Background/Objectives Idiopathic progressive subglottic stenosis (IPSS) predominantly affects females in perimenopause. It has, therefore, been hypothesized that estrogen is involved in its pathogenesis. There are two main types of estrogen receptors: ER‐α and ER‐β. Abnormal variants of ER‐β have previously been shown to be associated with poor wound healing. Estrogen receptors have recently been identified in subglottic tissue samples, with elevated levels of ER‐α and progesterone receptors, and...

The development and validation of the laryngopharyngeal measure of perceived sensation
Objectives Globus pharyngeus (GP) is described as the subjective sensation of having a “lump” in the throat in the absence of correlating physical findings or dysphagia. Historically, despite the frequency of patient complaints, GP has been difficult to quantify with current outcome measures. This is in large part due to lack of a user‐friendly, modernized, objective patient‐reported outcome measure (PROM) of symptom severity. The aim of this study is to develop a modernized, practical, validated...

Management of sporadic vestibular schwannoma with contralateral nonserviceable hearing
Objectives/Hypothesis To outline a possible decision‐making process for sporadic vestibular schwannoma (VS) with contralateral nonserviceable hearing at diagnosis. Study Design Retrospective case series. Methods Diagnosed VS was studied in a tertiary referral center from 1995 to 2013. Results Twenty‐eight patients were included, with a mean follow‐up of 6.9 years (range = 0.5–20 years). Ten were stage 1, 10 were stage 2, five were stage 3, and three were stage 4. Ipsilateral hearing...

Association of SLC26A4 mutations, morphology, and hearing in pendred syndrome and NSEVA
Objective To investigate the relations of monoallelic (M1), biallelic (M2), or the absence of mutations (M0) in SLC26A4 to inner ear morphology and hearing levels in individuals with Pendred syndrome (PS) or nonsyndromic enlarged vestibular aqueduct (NSEVA) associated with hearing loss. Methods In a cohort of 139 PS/NSEVA individuals, 115 persons from 95 unrelated families had full genetic sequencing of SLC26A4, and 113 had retrievable images for re‐assessment of inner ear morphology. The...
