Surgical removal of one half of the mandible, typically for treatment of malignant tumors.
Full Definition
Hemimandibulectomy is the surgical removal of one half of the mandible, usually performed as treatment for malignant tumors, extensive benign tumors, or severe trauma. The procedure involves sectioning the mandible at the midline and removing the affected side including the body, angle, ramus, and condyle. This extensive surgery requires immediate or staged reconstruction to restore facial contour, mastication, and speech function. Reconstruction options include vascularized bone flaps (fibula, iliac crest), titanium reconstruction plates, or a combination approach. The procedure has significant functional and aesthetic implications requiring multidisciplinary care.
Usage
Usage note: Extensive procedure requiring detailed documentation of reconstruction approach.
