Composite Chondromucosal Nasoseptal Flap for Reconstruction of Suprasellar Defects.

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.
