Behavioral audiometry may be of limited value for those patients who have incurred significant brain injury and remain unresponsive to auditory stimuli. Even the more "objective" tests such as auditory brainstem response (ABR) and acoustic reflex testing may be inadequate tools to assess peripheral auditory function when significant brainstem injury has occurred. Determination of peripheral hearing becomes important because rehabilitation strategies are anchored to the knowledge of sensory function prior to implementing appropriate plans of intervention. We present the usefulness of otoacoustic emission (OAE) testing to further evaluate the cochlear function in a patient with traumatic brain injury who was subsequently inconsistent in response to sound.

UI	MeSH Term	Description	Entries
D007806	Language Disorders	Conditions characterized by deficiencies of comprehension or expression of written and spoken forms of language. These include acquired and developmental disorders.	Acquired Language Disorders,Language Disorders, Acquired,Acquired Language Disorder,Language Disorder,Language Disorder, Acquired
D012022	Reflex, Acoustic	Intra-aural contraction of tensor tympani and stapedius in response to sound.	Acoustic Reflex
D001930	Brain Injuries	Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.
