Where should bone grafts be placed for a LeFort III procedure?

In a LeFort III procedure, bone grafts can be strategically placed in various locations to achieve optimal stability and integration of the maxillofacial structure. Each proposed site has its relevance depending on the goals of the surgery, such as enhancing support and facilitating healing.

Placement in the maxillary tuberosity is beneficial because it supports the posterior aspect of the maxilla and helps to stabilize the structure after osteotomies. This area can provide a good interface for graft incorporation with the surrounding bone.

The zygomatic/temporal region is another critical site because it can help reinforce the midface and zygomatic arch, which are essential for maintaining facial aesthetics and function. When performing a LeFort III osteotomy, ensuring that this area is well-supported helps prevent complications such as facial asymmetry.

The orbital region is also important for graft placement since the stability and integrity of the orbit are vital for proper ocular function and aesthetics. Grafting in this location can help ensure that the bony framework around the eyes is robust after the procedure.

By considering all these locations, the decision to place grafts in any or all of these sites ensures a comprehensive approach to achieving structural and functional stability following a LeFort III procedure. This flexibility highlights the importance of
