The sensitivity of auditory brainstem response testing for the diagnosis of acoustic neuromas.
OBJECTIVES To determine the sensitivity of auditory brainstem response (ABR) testing for detecting acoustic neuromas and to determine whether the test is less sensitive for detecting small tumors. DESIGN Retrospective review of the medical charts of 58 patients with acoustic neuroma who had all of the data necessary for inclusion in the study. SETTING University-affiliated referral practice...
متن کاملMouse Auditory Brainstem Response Testing.
The auditory brainstem response (ABR) test provides information about the inner ear (cochlea) and the central pathways for hearing. The ABR reflects the electrical responses of both the cochlear ganglion neurons and the nuclei of the central auditory pathway to sound stimulation (Zhou et al., 2006; Burkard et al., 2007). The ABR contains 5 identifiable wave forms, labeled as I-V. Wave I represe...
متن کاملThe importance of the auditory evoked potential in acoustic neuromas.
Hearing loss, frequently with tinnitus, is the main symptom of acoustic neuromas (ANs), which compress the cochlear nerve and affect the cochlear blood supply. This vascular mechanism explains why atypical, fluctuating deafness, with audiometric features of retrocochlear involvement, may occur in this condition. An early diagnosis of ANs is essential for a good prognosis. Physicians should reco...
متن کاملThe Sub-acute Effect of Lead Exposure on the Auditory Brainstem Response in Male Rats
Background: Lead is a major environmental pollutant and can adversely affect humans and animals. There are conflicting data about the ototoxic effect of lead. This study experimentally examined the association between blood lead levels (BLL) and the subsequent hearing impairment in male rats. Methods: Twenty-two male rats were randomly categorized into experimental (exposed to lead acetate, ...
متن کاملThe Relationship between Severe Hyperbilirubinemia and Abnormal Auditory Brainstem Response in children
Abstract:Background : Hyperbilirubinemia is one of the most common cause of congenital sensory neuronal hearing loss. These patients are screened by auditory brainstem response (ABR) test at bilirubin levels higher than 1% of gestational weight. Aim: to determine whether hyperbilirubinemia less than 1% of gestational weight could induce hearing loss and abnormal auditory brainstem response (ABR...
