What does auditory brainstem evoked potential mean?

Auditory brainstem evoked potential refers to the sound emitted through headphones stimulating the auditory nerve conduction pathway, and the potential is recorded on the top of the head. When brainstem auditory evoked potential is tested, the patient's cooperation is generally not required, and it can be measured in infants and coma patients. Auditory brainstem evoked potential can be used clinically to objectively evaluate hearing, pons, cerebellar tumor examination, multiple sclerosis, brain death judgment, and some can also be used for surgical monitoring. Brain death is mainly judged by EEG and brainstem auditory evoked potential. Surgical monitoring is mainly used for cerebellopontine angle tumor surgery. The important significance of multiple sclerosis lies in finding subclinical lesions and objectively evaluating hearing, especially for patients with hearing examination, infants, severe patients and consciousness disorders, which can help judge the degree of hearing impairment.
