落雷による外傷性鼓膜穿孔例 Lightning injury of the tympanic membrane : A case report
A 37-year-old man was struck by lightning on the beach during windsurfing. Although he lost consciousness and became cardio-respiratory arrest, fortunately, cardiopulmonary resuscitation was promptly performed by a nurse nearby, and he was restored. He was found to have the first and second grade linear burns i.e. lightning marks were observed on his right temporal, cervical, back, waist and inguinal region. After recovery from unconsciousness, he noticed right hearing loss and tinnitus. On examination, his right tympanic membrane was ruptured. A pure tone audiogram revealed averaged 20 dB conductive hearing loss. He was demonstrated neither any significant vestibular signs nor facial paralysis.<BR>Five months after the injury, because the perforation was not closed by conservative treatment, we performed myringoplasty using an underlay temporalis fascia graft. Eight months postoperatively the perforation was closed. On a pure tone audiogram, hearing was found within normal range.
