Abstract
In reconstruction of the anterior skull base, it is important to repair the dural defect to be a watertight, and to surely intercept between the cranial cavity and the nasal or para-nasal cavity. The temporal musculo-pericranial flap that is the local flap with the blood circulation is the most useful reconstructive material for the dural defect. In the interception between the cranial cavity and the nasal or para-nasal cavity, the frontal musculo-pericranial flap is used. The reconstructive method became safe by using these flaps. Therefore, it was standardized and adapted to the skull base injury in our institution.
We performed this reconstructive method on 53 cases after the resection of the tumor of the anterior skull base and the skull base injury. The local infection was developed in 5 cases and they were all healed by debridement and irrigation. None of the patients developed severe complication including liquorrhea, meningitis, or brain abscess. This method using these local flap was very safe and effective.
