Accidental [[anterior skull base defect]]s associated with [[surgery]] are difficult to treat. There are several [[method]]s for the [[repair]], yet [[postoperative rhinorrhea]] can occur despite the [[closure]]. A 56-year-old female patient was admitted for the treatment of a [[paraclinoid internal carotid artery aneurysm]]. The surgery included removal of the [[anterior clinoid process]], unroofing the [[optic canal]], decompressing the [[optic nerve]], and [[clipping]] the [[aneurysm]]. During the surgery, the [[planum sphenoidale]] was accidentally [[drill]]ed and the [[nasal cavity]] exposed. The [[dural defect]] was repaired using a U-[[flap]] [[technique]]. No postoperative [[cerebrospinal fluid rhinorrhea]] occurred in the [[patient]], and she was [[discharge]]d on [[postoperative]] day 3. On follow-up examination the patient did not have evidence of [[Cerebrospinal fluid fistula]]
