title: Periosteal reflection on the medial approach to the mandibular ramus in sagittal split ramus osteotomy.
abstract: We describe the modified medial opening to avoid blind procedures and to ensure periosteal dissection. The mucosal incision started behind the second molar and then wings laterally and forward at the lateral aspect. The medial subperiosteal dissection begins at the lingual border of the retromolar triangle. Minimal medial subperiosteal tunneling is performed only to identify the lingula. A medial osteotomy is performed above and 5 to 6 mm posterior to the lingula.
