Fibula osteoseptocutaneous free flap in maxillary reconstruction.

The skin paddle in the fibula osteoseptocutaneous flap is thin, soft, and pliable, and it can be used for external skin coverage and intraoral linings. The flexibility of the fibula in three-dimensional positioning after multiple osteotomies is desirable in complex spatial skeletal reconstruction. The fibula osteoseptocutaneous flap is suitable for one-stage reconstruction of composite maxillary defects. The unique characteristics of the fibula osteoseptocutaneous flap and its application in the one-stage composite maxillary defect are discussed.
