Which osteotomy is used to move the maxilla?

  1. LeFort I

  2. BSSO

  3. Genioplasty

  4. Sagittal split

The correct answer is: LeFort I

The correct answer is A. LeFort I osteotomy is used to move the maxilla. This procedure involves cutting the bone above the teeth and repositioning it to correct problems with the position or alignment of the maxilla. B. BSSO (Bilateral Sagittal Split Osteotomy) is a surgical procedure primarily used for mandibular (lower jaw) correction. C. Genioplasty is a surgical procedure to reshape the chin and does not involve the movement of the maxilla. D. Sagittal split osteotomy is used for mandibular advancement or setback, not for moving the maxilla.
