Objective. Enlarged vestibular aqueduct is the most common radiographically identified cause of congenital sensorineural hearing loss and is frequently progressive. Imaging is often ordered during the workup of children with congenital sensorineural hearing loss in part to identify enlarged vestibular aqueduct given concern for progression with head trauma. However, this association has not bee...

A 23-month-old female was referred for hearing aid fitting after failing newborn hearing screening and being diagnosed with significant hearing loss through subsequent diagnostic testing. Auditory brainstem response (ABR) and behavioral testing revealed a moderate-to-severe bilateral mixed hearing loss. Prior to the hearing aid evaluation, tympanostomy tubes had been placed bilaterally with lit...

OBJECTIVE A group of 20 patients with large vestibular aqueduct syndrome was identified at the Indiana University School of Medicine. The major objective of this study was to explore the improvements in quality of life associated with cochlear implantation in patients with large vestibular aqueduct syndrome, as well as the cost-utility of cochlear implantation in this group. SETTING A total o...

BACKGROUND A large vestibular aqueduct (LVA) is the most common inner ear anomaly found on the imaging evaluation of children with sensorineural hearing loss (SNHL). It is frequently associated with syndromic and nonsyndromic forms of SNHL or as an isolated finding. Large vestibular aqueduct syndrome can be characterized by delayed-onset, fluctuating, asymmetric, unilateral or bilateral SNHL or...

BACKGROUND AND PURPOSE The 45° oblique (Pöschl) plane allows reliable depiction of the vestibular aqueduct, with virtually its entire length often visible on 1 CT image. We measured its midpoint width in this plane, aiming to determine normal measurement values based on this plane. MATERIALS AND METHODS We retrospectively evaluated temporal bone CT studies of 96 pediatric patients without sen...
