Reconstruction of dural defects of the endonasal skull base.

Endonasal, endoscopic approaches to the cranial base have undergone significant technique refinement over the past decade. Repair of the resultant defects remains perhaps the most important concern with these approaches; however, recent advances suggest that with careful attention to the closure, these procedures can be done with acceptable rates of morbidity. In this review, the authors discuss known techniques for the repair of endonasal defects, and provide some insight based on their experience.
