Wideband acoustic immittance in superior semicircular canal dehiscence.

Objective: The apparent effect of superior semicircular canal dehiscence (SSCD) on middle ear- and cochlear impedance has led researchers to investigate the use of wideband acoustic immittance as a screening tool when SSCD is suspected. The purpose of the study was to describe the absorbance characteristics and tympanometric values of ears with confirmed SSCD measured at tympanometric peak pressure (TPP) and at ambient pressure.

Methods: Wideband Acoustic Immittance was performed at ambient pressure and at TPP on ten participants (12 ears) with confirmed SSCD, as well as on an age- and gender matched control group (12 ears).

Short-Term Test-Retest Reliability of Electrically Evoked Cortical Auditory Potentials in Adult Cochlear Implant Recipients.

Late latency auditory evoked potentials (LLAEPs) provide objective evidence of an individual's central auditory processing abilities. Electrically evoked cortical auditory evoked potentials (eCAEPs) are a type of LLAEP that provides an objective measure of aided speech perception and auditory processing abilities in cochlear implant (CI) recipients. To determine the short-term test-retest reliability of eCAEPs in adult CI recipients.

Vestibular involvement in adults with HIV/AIDS.

Objective: HIV/AIDS is responsible for widespread clinical manifestations involving the head, and neck. The prevalence and nature of vestibular involvement is still largely unknown. This study, aimed to describe and compare the occurrence and nature of vestibular involvement among a group of, adults infected with HIV compared to a control group.

Auditory and otological manifestations in adults with HIV/AIDS.

Objectives: This study describes the prevalence and nature of auditory and otological manifestations in adults with HIV/AIDS through clinical examinations and self-reported symptoms across stages of disease progression.

Design: Descriptive cross-sectional group design.

Study Sample: Two hundred HIV positive adult patients (56.

Sclerosing bone dysplasias: neurologic assessment and management.

Purpose Of Review: Sclerosing bone dysplasias are rare genetic disorders of bone remodeling in which excessive bone formation takes place, resulting in encroachment on neural structures. The infant usually appears normal at birth, and the first sign of a problem only comes when a neurologic deficit develops, usually in the form of an acute facial palsy. Although less than 300 cases have been published, these conditions should always be considered in the differential diagnosis of facial nerve palsy, especially in children.
