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.
