Summary: | We experienced a case of perilymphatic fistula with pneumolabyrinthine caused by old temporal bone fracture. A male in his 30s visited our hospital with a complaint of dizziness and left hearing impairment after blowing his nose. He had a history of old temporal bone fracture due to head trauma. Pure tone audiometry revealed a 53-dB hearing level with mixed hearing loss. Right horizontal and rotary mixed type nystagmus was observed. Temporal bone computed tomography showed a bone fracture line at the right temporal bone and a low-density area in the right utricle. Closure of perilymphatic fistula was performed at 13 days after the first symptom onset. A bone fracture line was noted between the prominence of the lateral semicircular canal and just lateral to the horizontal part of the facial nerve canal and anterior semicircular canal. Although the vestibular symptoms disappeared post-operatively, transient hearing loss occurred. His hearing level gradually recovered and improved to 33 dB. |
