When is item code 52342 (Unilateral Mandible or Maxilla Osteotomy) typically used?

The need for unilateral osteotomy or osteectomy of the mandible or maxilla arises when a patient requires surgical cutting or removal of a bone segment—often for deformity, tumour, or trauma—under anesthesia with assistance, including nerve and vessel transposition and same-site bone grafts to correct alignment or rebuild structure. This is indicated for unilateral issues needing precise adjustment, critical where jaw symmetry and function are affected in the maxillofacial region.

Reasons include:

  • Deformity: A crooked mandible might need osteotomy for symmetry.
  • Tumour: A benign growth could require osteectomy and grafting.
  • Trauma: A misaligned fracture needs cutting and repair.
  • Function: Corrects chewing or speech issues.

For example, a patient with a mandibular asymmetry might need this for aesthetics, with nerve care for sensation. In aged care, an elderly patient could benefit from this for function, given frailty. By adjusting bone, this service restores alignment, enhances function, and supports health, making it a key maxillofacial correction.

Benefits to the patient

Surgeons performing a unilateral osteotomy or osteectomy on the patient’s mandible or maxilla, including nerve and vessel transposition and bone grafts, under anesthesia with assistance provide corrective benefits. A primary advantage is correcting alignment. This procedure repositions the patient’s jaw, improving symmetry—crucial for 'jaw osteotomy benefits.' It also restores function by realigning the bone, enhancing the patient’s chewing or speaking abilities. Furthermore, it improves aesthetics by refining facial contours, boosting the patient’s appearance. For surgeons researching 'unilateral jaw surgery advantages,' this assisted service ensures patients experience alignment correction, functional restoration, and aesthetic enhancement, offering a comprehensive solution for jaw misalignment.

Recovery considerations

Recovery of 4-6 weeks with swelling and jaw care; bone healing extends time.
