Le fistole liquorali nella patologia otologica

Cerebrospinal fluid fistulas in the otologic pathology show the presence of one or more anomalous touches between subaracnoids spaces and temporal bone. Cerebrospinal fluid fistulas are distinguished in congenital and acquired. The acquired fistulas are the most large group and they include post-traumatic fistulas, post-infective fistulas and/or post-inflammatory fistulas, iatrogenic fistulas, post-neoplastic fistulas and spontaneous fistulas. The congenital fistulas are more rare, they involve otic capsula and are, often, associated with malformations of inner ear. The critical analysis of our data leads, in our opinion, to some interesting diagnostic considerations. © Copyright 2005, CIC Edizioni Internazionali.
