OBJECTIVE To describe temporal bone findings on computed tomography (CT) imaging in GJB2-related hearing loss (HL). We asked whether evaluation of the temporal bone is required in individuals with biallelic GJB2 mutations. STUDY DESIGN Randomized, blinded, controlled, prospective measurement. METHODS Blood from 264 pediatric cochlear implant users was analyzed for mutations in the GJB2 gene...
OBJECTIVE To determine whether congenital cytomegalovirus (CMV) infection is an etiologic factor in the pathogenesis of enlarged vestibular aqueducts (EVA). DESIGN Two different cohort studies. Subjects The study population comprised 19 subjects with a history of congenital CMV infection and sensorineural hearing loss (cohort 1); 39 subjects with nonsyndromic EVA and their unaffected mothers ...
HYPOTHESIS The human vestibular aqueduct (VA) shows great anatomical variations, and imaging can be difficult, so we need more data on the normal anatomy of the VA for better radiologic evaluation of large vestibular aqueduct syndrome (LVAS). BACKGROUND The normal anatomy of the human VA was analyzed in micro-dissected human temporal bones. METHODS The study is based on two sets of human te...
If a drastic change in hearing has occurred in a child following a minor head trauma, change in barometric pressure, or physical exertion, large vestibular aqueduct syndrome (LVAS) should be considered. Most audiologists are unaware of LVAS or do not suspect it, in part due to the presence of a conductive component. LVAS can be seen in conjunction with Mondini's dysplasia or may appear by itsel...
