[Iatrogenic CSF leak as a complication of osteoplastic flap surgery of the frontal sinus].

THE AIM OF THE STUDY: to evaluate CSF leak as a complication of osteoplastic flap surgery of the frontal sinus.

MATERIAL AND

METHODS

Medical recordings of the patients that underwent osteoplastic flap surgery of the frontal sinus were analyzed.

RESULTS

among 62 patients operated between 2000 and 2007 there were 4 cases of intraoperative CSF leak (6.5% of cases). In all complicated cases indication for surgery was benign large tumor of the frontal sinus, among them there were two cases of osteoma, one cholesterol granuloma and ossifying fibroma. All CSF leaks were successfully closed with multilayer underlay or overlay graft. The technical aspects of the osteoplastic flap surgery of the frontal sinus are discussed.
