[Intranasal endoscopic management of cerebrospinal rhinorrhea].

The excellent visualization and atraumatic surgical techniques of endoscopic sinus surgery have been applied to the management of five cases of cerebrospinal rhinorrhea in the last 3 years. In all the cases, the exact sites of the lesion were identified on ethmoid roof (2 cases) or sphenoid sinus (3 cases). The procedures of the operation were as follows: to enlarge the leak and at the same time to block up it with the muscles, and then covering the muscles with fascia. All of the five cases were cured by one-step surgery. The techniques and indications for endoscopic management of cerebrospinal rhinorrhea are discussed.
