Cerebrospinal fluid otorrhea and recurrent bacterial meningitis in a pediatric case with Mondini dysplasia

Mondini dysplasia is a congenital malformation of the inner ear, which is characterized by a short and large cochlear canal of 1.5 turn rather than 2.5 turns and an apical region with cystic dilatation. Patients present with congenital deafness, when both cochlea are affected. Unilateral disease may cause recurrent meningitis, otorrhea or rhinorrhea. In this article, we report a three-year-old pediatric case with a history of meningitis and cerebrospinal fluid otorrhea following tympanostomy tube placement for serous otitis media.
