When is item code 52345 (Unilateral Mandible or Maxilla Osteotomy with Fixation) typically used?

The need for unilateral osteotomy or osteectomy of the mandible or maxilla with fixation arises when a patient requires bone cutting or removal—often for 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 alignment and healing. This is indicated for complex unilateral issues, critical where stability enhances maxillofacial function.

Specific scenarios include:

  • Deformity: A mandibular shift needs osteotomy and plating.
  • Tumour: An osteectomy with screws rebuilds bone.
  • Trauma: A fracture requires cutting and fixation.
  • Stability: Ensures chewing or speech function.

For instance, a patient with a maxillary deformity might need this for alignment, with fixation for strength. In aged care, an elderly patient could benefit for function, given frailty. By cutting, grafting, and fixing, this service restores structure, enhances stability, and supports recovery, making it vital for complex maxillofacial repairs.

Benefits to the patient

Surgeons performing a unilateral osteotomy or osteectomy on the patient’s mandible or maxilla with fixation under anesthesia with assistance deliver robust benefits. A key advantage is restoring structure. This procedure realigns and stabilizes the patient’s jaw with grafts and hardware—vital for 'stabilized jaw surgery benefits.' It also ensures stability by securing the bone, supporting the patient’s long-term function. Additionally, it improves function by enhancing chewing or speaking, aiding the patient’s daily life. For surgeons exploring 'fixed osteotomy advantages,' this assisted service ensures patients benefit from structural restoration, lasting stability, and functional improvement, making it a durable fix for unilateral jaw issues.

Recovery considerations

Recovery of 6-8 weeks with swelling and fixation care; extended healing.
