Advancing Temporomandibular Joint Reconstruction: A Cadaveric Study on the Design of the Fourth Chondrocostal Joint Flap

This study demonstrates that the fourth chondrocostal joint flap is a promising free flap for temporomandibular joint and condylar reconstruction. It offers ideal pedicle positioning, length, and vascular size match at the anastomosis, making it a suitable technique for reconstructing the challenging temporomandibular region. This approach adds a new option to the reconstructive surgeon's armamentarium, addressing previous limitations in condylar reconstruction.
