“What Is The Difference Between A SARPE And A 2-Piece Segmental LeFort?”

6.28.24 Quick Review #160 - #surgery #surgeon #doctorgallagher #oralsurgery #oralsurgeon #omfs #dentist #dentistry #dental SARPE (Surgically Assisted Rapid Palatal Expansion) and a 2-part segmental LeFort I osteotomy are both surgical procedures used in orthognathic surgery, but they have different indications and techniques: SARPE (Surgically Assisted Rapid Palatal Expansion) 1. Purpose: SARPE is used to correct transverse maxillary deficiencies (narrow upper jaw) by expanding the maxillary arch. 2. Procedure: It involves making surgical cuts in the maxillary bone to facilitate the expansion of the palate. This is usually done in conjunction with a palatal expander device, which is gradually turned post-surgery to widen the maxilla. 3. Technique: The surgical cuts are typically limited to the lateral walls of the maxilla and occasionally the pterygoid plates. The midline suture of the palate is not fully separated; instead, it is partially released to allow for expansion. 4. Age Consideration: SARPE is often used in adults where the midpalatal suture has fused, making non-surgical expansion ineffective. 2-Part Segmental LeFort I Osteotomy 1. Purpose: A 2-part segmental LeFort I osteotomy is used to correct both vertical and horizontal discrepancies of the maxilla, such as in cases of severe malocclusion, open bites, and other maxillofacial deformities. 2. Procedure: This involves making a horizontal cut above the teeth, across the maxilla, and then segmenting it into two parts. This allows for movement of the maxilla in three dimensions to achieve the desired occlusal and aesthetic outcomes. 3. Technique: The LeFort I osteotomy involves a complete separation of the maxilla from the nasal septum and pterygoid plates. The maxilla is then segmented into two parts, which can be repositioned independently. 4. Complexity: The 2-part segmental LeFort I osteotomy is more complex and invasive compared to SARPE and requires more extensive planning and surgical skill. It allows for greater control over the repositioning of the maxilla in multiple planes. In summary, SARPE is primarily used for expanding a narrow maxilla transversely, while a 2-part segmental LeFort I osteotomy addresses more complex maxillofacial deformities by allowing multi-dimensional repositioning of the maxilla.
