Department of Bioacoustics, University of Bari, Italy.

One hundred thirty-nine cases of brain herniation into the middle ear and mastoid have been reported in the world literature during the last 40 years. In 29 cases the herniation was idiopathic. In idiopathic cases, intermittent CSF otorhinorrhea, a history of intermittent "serous otitis media," and a conductive hearing loss were the main clinical findings. Polytomography or CT-scan revealed a tegmen antri or tympani defect in some patients. There are three surgical approaches for treatment of brain herniation into the middle ear: neurosurgical, otological, and combined.

D002558	Cerebrospinal Fluid Otorrhea	Discharge of cerebrospinal fluid through the external auditory meatus or through the eustachian tube into the nasopharynx. This is usually associated with CRANIOCEREBRAL TRAUMA (e.g., SKULL FRACTURE involving the TEMPORAL BONE;), NEUROSURGICAL PROCEDURES; or other conditions, but may rarely occur spontaneously.

D004432	Ear, Middle	The space and structures directly internal to the TYMPANIC MEMBRANE and external to the inner ear (LABYRINTH). Its major components include the AUDITORY OSSICLES and the EUSTACHIAN TUBE that connects the cavity of middle ear (tympanic cavity) to the upper part of the throat.

D004677	Encephalocele	Brain tissue herniation through a congenital or acquired defect in the skull. The majority of congenital encephaloceles occur in the occipital or frontal regions. Clinical features include a protuberant mass that may be pulsatile. The quantity and location of protruding neural tissue determines the type and degree of neurologic deficit. Visual defects, psychomotor developmental delay, and persistent motor deficits frequently occur.
