Abstract

A 25-year-old man complained of hearing loss and vertigo occurred just after injuring the left ear drum with an ear pick. Pure tone audiometry showed a mixed hearing loss of 70.0dB. Vestibular function tests showed positional nystagmus. Exploratory tympanotomy was performed on 19 days after the onset following conservative therapy. Incudo-stapedial joint was dislocated and perilymphatic leakage from the oval window was observed. The window membrane was repaired with temporal fascia and ossicular chain continuity was reconstructed. Postoperatively hearing and vestibular symptoms were improved. This case suggested that immediate operation should be carried out in case that inner ear symptoms caused by direct trauma do not respond to conservative therapy.
