Abstract
Otolaryngologists play an important role in the management of CSF rhinorrhoea, the endonasal endoscopic route using a multilayer repair technique has definite advantages over more traditional methods because of low patient morbidity and a higher closure rate than single layer repair.
Endoscopic endonasal technique has a slow learning curve and requires additional training to master, including fellowship training, cadaveric workshops, and animal lab study. However, once mastered, these techniques can result in a significant reduction of complications and return of patients to their activities of daily living. Our results support the effectiveness and safety of this technique, and should encourage clinicians to apply the procedure in most cases of cerebrospinal fluid leak.
Proper diagnosis of the cause, site and CSF pressure prior to the endoscopic endonasal repair of skull base defects leaking CSF, proper decision making and good selection of cases for the endoscopic repair of the defect with treatment of the cause in cases of high CSF pressure and proper technique including adequate localization of the defect and use of multilayer repair and adequate post operative follow up and management of increase high CSF pressure increase success rate of the endoscopic repair.
