Frontobasal dura repair is necessary to prevent endocranial inflammations. However, identification and treatment of frontobasal dural lesions is still a challenge inregard to aetiology, location and size. The endonasal approach for duraplasty was recommended recently to provide a safe and effective repair of anterior skull base defects. The authors review their experiences with endonasal duraplasty. Diagnostic aspects and surgical techniques of proven value in endonasal repair of dural lesions are presented. From July 1980 to July 1996, 95 duraplasties have been performed in 92 patients via an endonasal approach at the ENT-Department, Fulda. A successful duraplasty was accomplished in 89 patients (97%) in the first attempt. In 2 patients, endonasal duraplasty had to be repeated to achieve a safe closure. In one case ofcomplex fractures of the sphenoid sinus and lateral skull base after a severe accident, the duraplasty of the sphenoid sinus was unsuccessful and an endonasal revision was indicated, but the patient died of cardiovascular shock. The Follow up period was from I to 16 years. Endonasal micro-endoscopic surgery offers the opportunity to repair frontobasal dural lesions in a safe and effective manner. Due to its low morbidity, high success rate and good long-term result, endonasal duraplasty is recommended as a main treatment modality in frontobasal dural lesions.
