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...

Surgery-first approach using a three-dimensional virtual setup and surgical simulation for skeletal Class III correction

A 19-year-old woman presented to our dental clinic with anterior crossbite and mandibular prognathism. She had a concave profile, long face, and Angle Class III molar relationship. She showed disharmony in the crowding of the maxillomandibular dentition and midline deviation. The diagnosis and treatment plan were established by a three-dimensional (3D) virtual setup and 3D surgical simulation, ...

Stability 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...

Vertical skeletal and facial profile changes after surgical correction of mandibular prognathism.

BACKGROUND Mandibular prognathism is often corrected by surgical orthodontics. Correction of the sagittal facial profile has received wide attention. However, vertical changes remained undefined and thus, were investigated. METHODS Subjects included 18 patients with mandibular prognathism who had surgical correction (S group, mean age: 20.1 +/- 3.2 years) and 18 patients with Class I malocclu...

Changes in the Gonial Angle Following Bilateral Sagittal Split Osteotomy and Vertical Ramus Osteotomy for Mandibular Excess

AIM The gonial angle plays an important role in ensuring a harmonious facial profile. Changes in this angle after surgery may be an esthetic concern for both the patient and the surgeon. The aim of the present study was to evaluate gonial angle changes after mandibular setback by the bilateral sagittal split osteotomy (BSSO) and vertical ramus osteotomy (VRO) techniques. METHODS Fifty-eight m...
