In simple words: This surgery involves cutting and reshaping the upper jaw bone to fix problems with the jaw's alignment or shape. The surgeon makes a cut in the mouth to reach the jawbone and carefully moves pieces of the bone into a better position, fixing them with small plates and screws.

This procedure involves surgically cutting and repositioning segments of the upper jaw (maxilla) to correct abnormalities and improve function or appearance.The surgeon makes an incision, typically inside the mouth, to access the maxilla. Precision instruments are used to carefully cut the maxilla into segments, following either the Wassmund or Schuchard technique.The segments are then repositioned to correct the deformity and secured using plates, screws, or other fixation devices. The incision is closed, and the surgical site is cleaned.

Example 1: A patient presents with a significant Class III malocclusion (underbite) that cannot be corrected with orthodontics alone.A segmental maxillary osteotomy (Schuchard) is performed to advance the maxilla, improving bite alignment and facial aesthetics., A patient with a congenital midface deficiency exhibits facial asymmetry and compromised breathing. A segmental maxillary osteotomy (Wassmund) is performed to augment the midface, correcting the asymmetry and improving respiratory function., A patient sustains a LeFort fracture in a motor vehicle accident, resulting in maxillary displacement and malocclusion.A segmental maxillary osteotomy is performed as part of the reconstructive surgery to reposition the maxillary segments, restore occlusion, and improve facial aesthetics.

Preoperative: Detailed clinical history including chief complaint, pertinent medical history, and physical examination findings.Radiographic imaging (e.g., panoramic radiographs, cephalometric radiographs, CT scans) to assess the skeletal structures and plan the surgery.Intraoperative:Detailed surgical record, including the type of osteotomy performed (Wassmund or Schuchard), measurements of bone segments, type of fixation used, and estimated blood loss.Postoperative:Postoperative clinical notes documenting pain management, healing, and functional outcomes.Follow-up radiographic imaging to assess bone healing.

** The choice between Wassmund and Schuchard techniques depends on the specific type and location of the maxillary deformity.Pre-authorization may be required by some payers to ensure medical necessity.
