mandibulectomy
Pronunciation: man-DIB-yoo-LEK-toh-mee
Surgical removal of part or all of the mandible (lower jaw bone), typically performed for tumor resection or severe trauma.
Full Definition
A major oral and maxillofacial surgical procedure involving the partial or complete removal of the mandible. This procedure is most commonly performed for malignant tumors, severe osteomyelitis, or extensive trauma that cannot be reconstructed. The extent of resection varies from marginal mandibulectomy (preserving the inferior border) to segmental or hemimandibulectomy. Reconstruction often requires bone grafts, plates, or microvascular free flaps to restore function and aesthetics.
Usage
Usage note: Distinguish from less extensive procedures like mandibular osteotomy or bone contouring.
