Recurrent hearing loss after myelography treated with epidural blood patch.

Transient hearing impairment is a known sequel after various procedures that result in loss of cerebrospinal fluid, such as lumbar puncture, spinal anesthesia and myelography. But persistent or recurrent hearing loss after dural puncture is a rare entity. We present a case with recurrent low-frequency sensorineural hearing loss after myelography. The patient was treated successfully by means of an epidural blood patch, although the conservative treatment was ineffective.
