Revision endoscopic skull-base surgery

Revision skull-base surgery (SBS) should be practiced within a multidisciplinary team. • Standard endoscopic sinus instrumentation is often inadequate for SBS and specialized equipment is required. • Closure of large skull-base defects requires careful preoperative evaluation and planning of reconstructive options. • The use of pedicled mucosal flaps and a multilayered reconstruction is the key to closing large skull-base defects. • The potential for complications differs little from open SBS, but the ability for faster recovery and less morbidity is great.
