[Diagnosis and management of Mondini malformation].
Owing to the development of imaging technology and audiology, some of the sensorineural hearing loss cases that were previcusly considered to be of unknown cause have been found to be inner ear malformation. Five cases of Mondini malformation are reviewed in this paper. CSF otorhinorrhea occurred in four cases, Klippel-Feil syndrome in three, and concurrent otosclerosis in one patient. In discussion, the authors point out that: 1) CT scanning is an supplement to audiologic tests for such patients; 2) perilymph fistula in Mondini malformation is often found at the oval window and its vicinity, the foot plate and the round window; 3) the fistula can be treated by plugging with fascial tissue via tympanoplastic approach with endaural incision. The mucosa around the fistula should be stripped away and the plugging tissue should be of dumb-bell shape.
