Males constitute 68% (n = 203) of total operated PBC patients while the rest 32% (95) were females, making the male-to-female ratio 2.2:1. The age in this series ranged from 9 to 85. According to updated Sanna's PBC classification, 44% were supralabyrinthine, 33% were massive, 9% were infralabyrinthine-apical, 8% were infralabyrinthine, and 5% were apical. On preoperative FN function examination, 45% (n = 133) of patients had various degrees of paresis and complete paralysis whereas 55% (n = 165) had normal FN function. The commonest degree of paresis observed was HB-III (18.5%) followed by HB-IV (5.7%). A total of 40(13.4%) patients, however, had complete facial paralysis at the initial presentation. The facial function was compromised more frequently in supralabyrinthine and massive PBCs. Among the total patients who had an abnormal facial function at presentation, 52% had paresis/paralysis for less than a year whereas 48% had FN paresis/paralysis for greater than one year. The most commonly used surgical approaches at our center were transotic (TO), modified transcochlear type A (MTCA) with rerouting of the FN, and translabyrinthine (TLAB) with external auditory canal (EAC) closure.
