Surgical Management Of Spontaneous Temporal Bone Cerebrospinal Fluid Leaks: Results Of A Strategy Based On Defect Location. A Bicentric Retrospective Study Of 44 Cases

Cerebrospinal fluid (CSF) leaks of the temporal bone may be traumatic, iatrogenic, or spontaneous. The main risk of these CSF leaks is the occurrence of meningitis or of other intracranial infectious complication (1). Unlike traumatic CSF leaks, that usually stop spontaneously, iatrogenic and spontaneous leaks require a surgical closure (2). Some authors advocate a transmastoid approach, while others recommend a middle cranial fossa (MCF) approach.
