Which surgical approach is commonly used for a Le Fort I osteotomy?

The intraoral approach is commonly used for a Le Fort I osteotomy because it allows access to the maxilla through the oral cavity without the need for external incisions. This minimally invasive route enhances patient recovery and reduces scarring since the incision is made inside the mouth. The intraoral approach facilitates precise osteotomies of the maxilla while preserving the facial aesthetics and minimizes postoperative complications related to external wound healing.

In performing a Le Fort I osteotomy, the surgeon can mobilize the maxilla effectively, allowing for desired vertical and horizontal repositioning. The access provided by this approach is sufficient for adequately visualizing the surgical field while maintaining a comfortable experience for the patient due to the absence of visible incisions on the face.

In contrast, other options like the transoral and submental approaches are not preferred for this specific procedure due to limitations in access and visibility. The external approach, while applicable in other maxillofacial procedures, is not used for Le Fort I as it introduces additional scarring and potential complications associated with external incisions. Thus, the intraoral approach is the optimal method for performing a Le Fort I osteotomy.
