Patient's question:
The left and right sides of waves I, III, and V show good divergence. The latency of each wave and the interpeak latencies of I-III, III-V, and I-V are prolonged. Auditory brainstem response threshold: V wave can be observed in both ears at 25 dB. Note: Abnormal brainstem auditory evoked potential, recommend periodic follow-up.Doctor's answer:
The brainstem auditory evoked potential (BAEP) test is a method of assessing whether there are abnormalities in the auditory nerve pathway by artificially administering sound stimuli and recording the generated potential signals on the head. It does not involve craniotomy. It is a very routine examination. Wave 4 is generally not evaluated clinically, as these waves are produced during the conduction process, and there is significant variation in latency, amplitude, and reproducibility among individuals. Therefore, Wave 4 is typically not considered. If the report concludes with Wave 4, the interwave intervals become disordered, and there are no reference normal values. Thus, this result is difficult to interpret.
