Background and Objectives Auditory brainstem response (ABR) can be utilized to verifythe hearing threshold and determine the existence of retrocochlear pathology in sudden deafness. However, little is known about the significance of ABR characteristics as a prognosticfactor in sudden deafness. The purpose of this study is to evaluate which characteristics ofABR is associated with the prognosis of sudden deafness. Subjects and Method We studied patients who were diagnosed with unilateral suddendeafness from January 2017 to May 2018. ABR results of click stimuli at 90 dB nHL were analyzedby the latency of wave I, III, and V. Results A total of 113 patients (55 men and 58 women) participated in the study. Hearing recoverywas observed in 94 cases (83.2%). The absolute latency of wave I, III, and V was prolongedin the affected ears when compared with the unaffected ears. Hearing improvementwas only correlated to the interaural latency delay of wave I (Pearson’s r=-0.278, p＜0.05). Prolonged interaural latency delay was noted from complete toward slight hearing recoverygroup. When the hearing outcome was evaluated by the interaural latency delay of wave I at0.2 ms, the result of under 0.2 ms was significantly better than that over 0.2 ms and no visiblewave I. Conclusion Prolonged interaural delay of wave I over 0.2 ms and no visible wave I in ABRshowed worse hearing outcome in sudden deafness. This finding may provide ABR as a potentialprognostic indicator in sudden deafness.
