[Mondini-type petrous bone dysplasia as a cause of spontaneous otoliquorrhea]
Abstract:
A case of fistula formation in a congenitally deformed petrous bone is described. This case demonstrates the diagnostic problem of deafness with spontaneous cerebrospinal fluid otorrhoea causing recurrent meningitis. Methods of diagnosis and therapy are discussed and the value of hypocycloidal polytomography is stressed.
