박동성 이명을 유발한 자발성 측두골 수막류의 수술적 치료|RISS 상세보기

다국어 초록 (Multilingual Abstract)

A meningocele is a protrusion of meninges through a defect in the skull base. It is a rare but potentially life-threatening condition requiring surgery. It can present with conductive hearing loss, persistent middle ear effusion, cerebrospinal fluid otorrhea, recurrent meningitis, and epilepsy. We report a patient who presented with a three-year history of intermittent pulsatile tinnitus in her left ear. She had clear middle ear effusion and radiological evaluations suggesting an attic cholesteatoma. She underwent a tympanomastoidectomy and we discovered a meningocele in the epitympanum and a bony defect of the tegmen tympani. We easily restored the meningocele using a microelevator and bolstered the bone with temporalis fascia, conchal cartilage and musculoperiosteal flap. There was no evidence of cerebrospinal fluid leakage and the patient’s tinnitus disappeared six months after the operation.
