maxillectomy
Pronunciation: mak-SIL-ek-toh-mee
Surgical removal of all or part of the maxilla (upper jaw bone), usually performed for tumor resection.
Full Definition
A complex oral and maxillofacial surgical procedure involving partial or total removal of the maxilla. Classifications include limited maxillectomy (preserving the orbital floor), subtotal maxillectomy (removing the hard palate), and total maxillectomy (including orbital contents). The procedure is primarily indicated for malignant tumors, extensive benign lesions, or severe trauma. Reconstruction may require obturators, bone grafts, or microvascular free flaps to restore oral function and facial aesthetics.
Usage
Usage note: Specify the extent of resection (limited, subtotal, or total) in surgical documentation.
