New approach to the endoscopic repair of a CSF leak originating from the lateral recess of the sphenoid sinus

Abstract

Difficult access can make identification of a cerebrospinal fluid leak from the lateral wall of the sphenoid sinus very difficult, especially in a well-pneumatized sinus. Access to the sphenoid sinus has become easier with the advancement of minimally invasive endoscopic technology. In this article we describe our approach to a cerebrospinal fluid leak originating from this location, which has not been described previously in the literature.
