OBJECTIVE To examine whether microdebrider intracapsular tonsillotomy (MT) results in less postoperative pain compared with electrosurgical extracapsular tonsillectomy (ET). DESIGN Prospective, randomized, double-blind, matched pair, clinical trial. SETTING Specialty care hospital. Patients Twelve male (48%) and 13 female (52%) children aged 5 to 15(More)
OBJECTIVE To validate a parent proxy instrument to study the voice-related quality of life (VR-QOL) for the pediatric population. METHODS The voice outcome survey (VOS) was administered to 108 caregivers of children aged 2 to 18 years, who either had a tracheotomy or had achieved surgical decannulation. The VOS was altered so that each item was addressed(More)
OBJECTIVES To report our experience with all patients diagnosed with type 1 laryngeal cleft over a period of 3 years in our referral practice and to describe a functional diagnostic and management algorithm for children with this disorder. METHODS A prospective longitudinal study in a tertiary care referral center. Twenty pediatric patients diagnosed with(More)
OBJECTIVES To describe (1) a cohort of children with paradoxical vocal-fold motion (PVFM) who were referred to a multidisciplinary airway center and (2) the outcomes of various treatment modalities including speech therapy, gastroesophageal reflux disease treatment, and psychiatric treatment. PATIENTS AND METHODS This was a case series with chart review(More)
OBJECTIVE To identify characteristic patterns of maturation of the human vocal fold lamina propria as it develops into a mature structure. METHODS Histologic evaluation of sectioned true vocal folds from 34 archived larynges ages 0 to 18 years using hematoxylin-eosin, trichrome, Alcian blue pH 2.5, Weigert reticular, and Miller's elastin stain. LOCATION(More)
OBJECTIVE We investigated trends in noise-induced threshold shifts (NITSs), high-frequency hearing loss (HFHL), and low-frequency hearing loss (LFHL). METHODS A total of 4310 adolescents 12 to 19 years of age completed audiometric testing during National Health and Nutrition Examination Surveys in 1988-1994 and 2005-2006.

OBJECTIVE To evaluate the degree of neovascularization and efficacy of repair of chronic tympanic membrane perforations in a chinchilla model using poly(glycerol sebacate) (PGS), a novel bioengineered scaffold material. STUDY DESIGN A feasibility study in which chinchilla ears with chronic perforations were randomly assigned to repair with PGS plugs or(More)
OBJECTIVE To design and implement a functional magnetic resonance imaging (fMRI) protocol to investigate the cortical and brainstem patterns of activity in children with regard to the act of swallowing. STUDY DESIGN Pilot study to assess the clinical feasibility of the project. METHODS Using a 3T Bruker Biospec 30/60 MRI scanner, images were obtained(More)
OBJECTIVE This clinical consensus statement (CCS) aims to improve care for pediatric and adult patients with a tracheostomy tube. Approaches to tracheostomy care are currently inconsistent among clinicians and between different institutions. The goal is to reduce variations in practice when managing patients with a tracheostomy to minimize complications. (More)
