Abstract:
Recently, brainstem auditory evoked potential is very important for the evaluation of functions of the 8th nerve & brainstem. Especially, it appears that waves I, III, and V primarily represent volume- conducted electrical activity from the acoustic nerve, pons and midbrain, respectively, and that latencies between these three potentials indirectly reflect neural conduction in the corresponding segments of the central auditory pathway. For example, wave I to wave III interpeak latency(I-III IPL) is a measure of conduction in the more caudal segment of the brainstem auditory pathway-acoustic nerve and potomedullary portion-while the III-V IPL is a measure of conduction in the more rostral pontine and midbrain portions of the pathway. This study was undertaken to identify the normal measurements of the waves I, III and V and I-III IPL, III-V IPL in order to for provide basic data for clinical use in diagnosis, monitering in operation and management of patients with brainstem lesions. The literature is reviewed and results compared to the current study.
