The sagittal split ramus osteotomy as the preferred treatment for mandibular prognathism.
نویسنده
چکیده
The SSRO with rigid fixation (RF) can be best applied for correction of mandibular prognathism after the age of 12 years (after eruption of the mandibular second molars) in symmetric and mild to moderate asymmetric cases. Contraindications for the SSRO include 1) presence of unerupted mandibular second molars: 2) a severely narrow anteroposterior or mediolateral dimension of the ramus with no medullary bone between the buccal and lingual cortices; and 3) severe mandibular asymmetry.

Complications of Bilateral Sagittal Split Osteotomy in Patients with Mandibular Prognathism
Introduction: Bilateral sagittal split osteotomy (BSSO) of mandible is vastly used in treatment of mandibular deficiencies and discrepancies. Since this method could affect esthetic as well as function, evaluating these effects from various aspects is crucial. This study assessed the effects of this technique on the function of masseter muscle, jaw movements, and sensory changes along with fail...

Statement of Problem:The choung osteotomy (Intraoral Vertico- Sagittal Ramus Osteotomy) has developed since 1992 in the treatment of mandibular prognathism. In IVSRO, osteotomy plane is theoretically parallel to the original sagittal plane and thereby attempting to decrease the incidence of condylar dispacement. This osteotomy designed additionally to decrease neurosensory disturbances.Purpose...
متن کاملRigid fixation of intraoral vertico-sagittal ramus osteotomy for mandibular prognathism.
The standard surgical treatment for mandibular prognathism is sagittal split ramus osteotomy (SSRO) if the proximal and distal segments of the ramus require fixing with screws or metal plates. In this procedure, however, it is frequently difficult to avoid neurosensory disturbance (NSD) of the inferior alveolar nerve (IAN) when the posterior margin of the ramus curves inward or when the ramus i...
متن کاملStability of unilateral sagittal split ramus osteotomy for correction of facial asymmetry: long-term case series and literature review
Bilateral sagittal split ramus osteotomy is considered a standard technique in mandibular orthognathic surgeries to reduce unexpected bilateral stress in the temporomandibular joints. Unilateral sagittal split ramus osteotomy (USSO) was recently introduced to correct facial asymmetry caused by asymmetric mandibular prognathism and has shown favorable outcomes. If unilateral surgery could guaran...

Background and Aim: Proximal segment movements following different methods of ramus osteotomy is one of the undesired consequences of orthognathic surgery. Theoretically, it seems that intraoral verticosagittal ramus osteotomy can minimize the movement of proximal segment. In this study, changes in intergonial distance and ramus flaring angles were evaluated and compared in transverse plane aft...
