“…Between peak latencies and interpeak latencies, the latter is the more clinically useful marker because peak latencies are more susceptible to influence from external factors such as age, thus rendering them less reliable. 71 However, the majority of these parameters are, at best, warning signs that alert the surgeon; among them, only maintenance of Waves I and V has been consistently shown to correlate with better postoperative hearing preservation rates, 34,50,88,91,98,121,136,141,146 although others have found poor hearing outcomes despite wave preservation. 30,59 The prognostic power of BAEPs is based solely on the preservation of the waves; in other words, when actual changes are seen on BAEPs, the severity or presence of postoperative deficits cannot be predicted reliably.…”
