Condylar displacement and temporomandibular joint dysfunction following bilateral sagittal split osteotomy and rigid fixation.
In this study changes in intercondylar width (ICW) and intercondylar angle (ICA) that occurred with rigid fixation after bilateral sagittal split osteotomy and mandibular advancement are documented and correlated with temporomandibular (TM) symptoms, magnitude of advancement, and mandibular shape. Even though individual changes occurred, there was no significant difference between the mean preo...

متن کاملEndoscopic-assisted medial osteotomy during sagittal split ramus osteotomy.
In this article, we describe endoscopic-assisted medial ramus osteotomy during sagittal split ramus osteotomy (SSRO). Surgical repositioning of the mandible by bilateral SSRO has become a safer and more reliable procedure through ingenuity of surgical methods, development of special instruments and improvement of surgical skills. The horizontal medial osteotomy should be located at or just abov...
متن کاملHorizontal changes in the condylar head after sagittal split ramus osteotomy with bent plate fixation.
OBJECTIVE The purpose of this study was to evaluate the horizontal changes in the condylar head with bent plate fixation after sagittal split ramus osteotomy (SSRO) with and without a Le Fort I osteotomy. STUDY DESIGN Of 47 Japanese patients with mandibular prognathism, 24 underwent SSRO and 23 underwent SSRO in combination with a Le Fort I osteotomy. A 3-5-mm gap was made between the proxima...
