**Core Concept**
Sagittal split osteotomy is a surgical procedure used in orthognathic surgery to correct mandibular deformities, such as prognathism or retrognathism. This procedure involves cutting the mandible in a sagittal plane and repositioning it to achieve proper occlusion and facial symmetry.
**Why the Correct Answer is Right**
Sagittal split osteotomy was first advocated by Paul Tessier, a French oral and maxillofacial surgeon, in the 1960s. This procedure allows for the correction of mandibular deformities by repositioning the mandible in a controlled manner. The procedure involves making an incision in the mandible and using a saw to cut through the bone, creating a split. The mandible is then repositioned and secured in place using plates and screws.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the procedure was not first advocated by this individual. While they may have contributed to the development of sagittal split osteotomy, they are not credited with its initial advocacy.
**Option B:** This option is incorrect because the procedure was not first advocated by this individual. They may have performed the procedure or written about it, but they are not credited with its initial advocacy.
**Option C:** This option is incorrect because the procedure was not first advocated by this individual. They may have contributed to the development of sagittal split osteotomy, but they are not credited with its initial advocacy.
**Clinical Pearl / High-Yield Fact**
Sagittal split osteotomy is a complex surgical procedure that requires a thorough understanding of the anatomy of the mandible and the principles of orthognathic surgery. It is essential to carefully plan and execute the procedure to achieve optimal results and minimize complications.
