Background:
The pedicled nasoseptal flap (NSF) is the mainstay for endoscopic skull base reconstruction. We present a novel technique using a semirigid chondromucosal NSF that improves the reinforcement and protection of intracranial structures.
Methods:
Composite NSFs were performed to repair intraoperative high-flow cerebrospinal fluid leaks in 2 patients who had undergone endoscopic endonasal resection of a suprasellar mass. The surgical technique and postoperative outcomes are described.
Results:
The flaps were sufficient for defect coverage, and the patients did not experience any cerebrospinal fluid leak in the immediate and delayed postoperative periods. No complications related to the composite flap had developed.
Conclusions:
The composite chondromucosal NSF is a reliable reconstruction option for select ventral cranial base reconstruction cases with the potential to improve the protection of intracranial structures. Additional surgical cases and longer follow-up are required for a better assessment of long-term outcomes.
