UNASSIGNED: Microsurgery is one of the primary current standard options for the treatment of @entity5513 ( @entity5513 ). Especially the middle cranial fossa (MCF) approach is a safe and efficacious technique for the preservation of hearing and @entity2103 in small @entity5513 . @entity260 are rare, although a leakage of cerebrospinal fluid (CSF) is common. The aim of this study was to analyze postoperative CSF leaks and to describe strategies for postoperative treatment. Between October 2005 and May 2012, 148 @entity1 suffering from @entity5513 and selected for microsurgery via the MCF approach were treated in our department. Postoperative CSF leakage occurred in 19 @entity1 . We found a leakage via the Eustachian tube into the nasopharynx in 18 @entity1 and one case of incisional leakage. In 13 cases leaking stopped within 5  days by conservative management including bed rest and intravenous (i.v) antibiotics. Five @entity1 needed lumbar drainage (LD) and only two @entity1 had to undergo revision surgery to seal and pack the mastoid. Analyzed risk factors were age, gender, @entity5 size and pneumatization of the mastoid. Only the latter showed a significant influence on CSF leakage. We could demonstrate that a stepwise strategy is needed for successful treatment of CSF leaks.
