Reconstruction midface, LeFort I; single piece, segment movement in any direction (eg, for Long Face Syndrome), without bone graft

The procedure described by CPT® Code 21141 involves the surgical reconstruction of the midface using a technique known as LeFort I osteotomy. This specific procedure is performed as a single piece segment movement, which allows for the repositioning of the maxilla, or upper jaw, in any direction. It is particularly indicated for patients with congenital facial bone deformities, such as Long Face Syndrome, or for cosmetic enhancements. The LeFort I osteotomy focuses on the lower maxillary region, which is anatomically defined as the area below the infraorbital nerve and medial to the zygomatic-maxillary suture. During the procedure, the physician does not utilize bone grafts, which distinguishes it from other reconstructive techniques that may require additional bone material for support or structure. The surgical approach includes careful manipulation of the maxilla, ensuring that the integrity of surrounding tissues is maintained while achieving the desired aesthetic and functional outcomes.
