When is item code 52366 (Complex Bilateral Osteotomy (3+ and 2 Procedures)) typically used?

The need for complex bilateral osteotomies or osteectomies involving three or more procedures on one jaw and two on the other, including genioplasty, arises when a patient requires extensive correction of both mandible and maxilla—often for severe deformity or pathology—under anesthesia with assistance, including nerve and vessel transposition and same-site grafts to adjust complex asymmetry or rebuild structure. This is indicated for intricate bilateral issues, critical where jaw balance and chin position affect maxillofacial function.

Reasons include:

  • Severe deformity: Complex jaw misalignment needs multiple cuts.
  • Tumours: Extensive growths require osteectomies.
  • Genioplasty: Chin adjustment enhances symmetry.
  • Function: Restores chewing or speech.

For example, a patient with a severely crooked jaw and chin might need this for balance, with grafts for strength. In aged care, an elderly patient could benefit for function, given frailty. By adjusting both jaws and chin, this service restores symmetry, enhances function, and supports health, making it a key maxillofacial correction.

Benefits to the patient

Surgeons performing complex bilateral osteotomies or osteectomies on the patient’s mandible and maxilla, with multiple procedures and genioplasty, under anesthesia with assistance offer extensive benefits. A key advantage is correcting complex asymmetry. This procedure addresses the patient’s multifaceted jaw issues, improving balance—essential for 'complex jaw asymmetry benefits.' It also restores function by realigning both jaws comprehensively, enhancing the patient’s capabilities. Furthermore, it improves aesthetics by refining contours, including the chin, boosting the patient’s appearance. For surgeons researching 'complex bilateral osteotomy advantages,' this assisted service ensures patients experience asymmetry correction, functional restoration, and aesthetic enhancement, providing a thorough solution for intricate jaw conditions.

Recovery considerations

Recovery of 8-12 weeks with swelling and jaw care; bone healing takes time.
