OBJECTIVE The purpose of this research was to compare the signal-to-noise ratio required for equal performance for children (aged 6-14 years) with normal hearing (N=17) versus those with severe-to-profound unilateral hearing impairment (N=20) who can be at a disadvantage, particularly when sounds are presented to the impaired ear. The listening environment(More)
Exercise-induced laryngomalacia (EIL) is characterized by inspiratory stridor that is brought on by exercise (i.e. competitive sports) and fails to respond to treatment with bronchodilators (Smith et al., Ann Otol Rhinol Laryngol 1995;104:537-541). During exercise, (1) spirometric flow volume loops show evidence of variable extrathoracic obstruction, and(More)
OBJECTIVE To compare disease response among children with recurrent respiratory papillomatosis (RRP) who underwent combined surgical debulking and intralesional cidofovir injections vs repeated surgical debulking only. DESIGN Retrospective medical record review; follow-up range: 16 to 56 months. SETTING Tertiary care children's hospital. PATIENTS(More)
OBJECTIVE To compare temporal bone computed tomography (CT) with temporal bone and central nervous system magnetic resonance (MR) imaging in children with unilateral or asymmetric sensorineural hearing loss (SNHL). DESIGN Retrospective chart study. SETTING Tertiary-care children's hospital. PATIENTS A total of 131 children with unilateral or(More)
Previous studies have shown evidence of cortical reorganization following unilateral sensorineural hearing loss (USNHL). In addition, study participants with right USNHL have shown greater deficits in academic and language performance compared with those with left USNHL. A preliminary functional magnetic resonance imaging investigation was performed on a(More)
OBJECTIVE The study goal was to determine the prevalence and clinical significance of a large vestibular aqueduct (LVA) in children with sensorineural hearing loss (SNHL). STUDY DESIGN AND SETTING We conducted a retrospective review of a pediatric SNHL database. One hundred seven children with SNHL were selected and their radiographic and audiometric(More)
OBJECTIVE To identify factors responsible for delays in diagnosis and treatment of pediatric sensorineural hearing impairment (SNHI), and to assess the thoroughness of medical evaluation in these children. DESIGN Retrospective analysis. SETTING State-supported school for the deaf. PATIENTS AND OTHER PARTICIPANTS 291 children with SNHI, the bast(More)
OBJECTIVE To correlate genetic and audiometric findings with a detailed radiologic analysis of the temporal bone in patients with enlarged vestibular aqueduct (EVA) to ascertain the contribution of SLC26A4 gene mutations to this phenotype. DESIGN A retrospective review of patients with EVA identified in a database of pediatric hearing-impaired patients.(More)
OBJECTIVE To measure the quality of outpatient surgery in an ambulatory surgery center (ASC) compared to a hospital-based facility (HBF) in a multidimensional manner. STUDY DESIGN Cross-sectional survey based on chart review. SETTING Pediatric academic health center. SUBJECTS AND METHODS A total of 486 cases were reviewed. Procedures were performed at(More)
