(A) Otoscopic examination reveals streak-like structure (asterisk) behind the eardrum. Yellowish bundle-like structure is placed at postero-superior quadrant. P, posterior canal wall; A, anterior canal wall. (B) External ear shows normal structure without anomaly. (C) Pure tone audiometry shows conductive hearing loss; air-bone conduction gap of 58 dB in the left ear. (D) Facial nerve dehiscence of tympanic segment, which is seen behind the tympanic membrane (white arrow). (E) Incudostapedial dislocation (white arrow) with lateralized facial nerve (white arrow head). (F) Intermediate signal intensity of the aberrant facial nerve course. (G) Well-delineated facial and vestibulocochlear nerve in internal auditory canal.
