[Recurrent meningitis, hydrocephalus and tegmen tympani dehiscence]

Cerebrospinal fluid (CSF) otorrhea is the usual presenting symptom of spontaneous tegmen tympani defects. A case associated with recurrent meningitis and CSF rhinorrhea without otorrhea is described. The coexistence of an hydrocephalus had led initially to ventriculoperitoneal shunting, which did not prevent meningitis recurrence. Previously reported in cases of anterior fossa and sella defects, an aqueduct stenosis was here associated with the tegmen tympani defect.
