When is item code 52363 (Bilateral Mandible and Maxilla Osteotomy with Fixation (2 Procedures Each)) typically used?

The need for osteotomies or osteectomies with two procedures on each jaw, including fixation, arises when a patient requires bilateral correction of both mandible and maxilla—often for severe deformity or pathology—under anesthesia with assistance, including nerve and vessel transposition, same-site grafts, and stabilization with wires, screws, plates, or pins to ensure symmetry and healing. This is indicated for complex bilateral issues needing robust repair, critical where jaw stability supports maxillofacial function.

Specific scenarios include:

  • Deformity: Bilateral misalignment needs dual cuts and plating.
  • Tumours: Bilateral osteectomies with screws rebuild bone.
  • Trauma: Double fractures per jaw require fixing.
  • Stability: Ensures chewing or speech function.

For instance, a patient with a severe bite issue might need two osteotomies per jaw with plates for alignment. In aged care, an elderly patient could benefit for function, given frailty. By cutting, grafting, and fixing both jaws, this service restores structure, enhances stability, and supports recovery, making it essential for extensive maxillofacial repairs.

Benefits to the patient

Surgeons performing dual osteotomies or osteectomies on both the patient’s mandible and maxilla with fixation under anesthesia with assistance deliver comprehensive benefits. A key advantage is restoring bilateral structure. This procedure realigns and stabilizes both jaws with grafts and hardware—vital for 'fixed dual jaw surgery benefits.' It also ensures stability by securing both sides, supporting the patient’s long-term function. Additionally, it improves function by enhancing bite and speech, aiding the patient’s quality of life. For surgeons exploring 'stabilized dual osteotomy advantages,' this assisted service ensures patients benefit from structural restoration, lasting stability, and functional enhancement, providing a robust fix for dual-jaw issues.

Recovery considerations

Recovery of 6-10 weeks with swelling and fixation care; extended healing.
