Influence of Osteotomy Design on Bilateral Mandibular Ramus Sagittal Split Osteotomy
Journal of Oral and Maxillofacial Surgery, 2015The mandibular ramus sagittal split osteotomy is the most popular procedure for repositioning themandible for orthognathic surgery. Compared with other techniques, such as a vertical ramus osteotomy or inverted L-osteotomy, the sagittal split osteotomy provides a better bony interface to supplement healing and allows easier adaption of rigid fixation ...

Anatomic Study for the Horizontal Cut of the Sagittal Split Ramus Osteotomy
Journal of Oral and Maxillofacial Surgery, 2013The purpose of this study was to determine the posterior extension of trabecular bone and the height at which both the lateral and medial cortical bone layers of the mandibular ramus merge, using a reference point on the anterior margin of the mandibular ramus.A total of 80 adult human mandibles were studied.

Condylar Positioning in Sagittal Split Ramus Osteotomy by the Triangle Method
Annals of Plastic Surgery, 2005Several methods for maintaining the preoperative condyle position after mandibular ramus surgery have been suggested. But when applied, those have been proven to be uncomfortable and less practical; hence, maintaining preoperative condyle position has mainly relied on the operator's personal experience.We developed a new technique on the basis of the ...

Vulnerable Structures During Intraoral Sagittal Split Ramus Osteotomy
Journal of Craniofacial Surgery, 2009The aim of this study was to elucidate the anatomical structures that are vulnerable to injury during sagittal split ramus osteotomy (SSRO). Twenty-nine hemifaces of 19 Korean adult cadavers (11 men and 8 women; age range, 50-91 years) were dissected, and the locations of the facial nerve, retromandibular vein (RMV), and external carotid artery (ECA ...

Technical Modification Designed to Facilitate Sagittal Split Ramus Osteotomy
Journal of Oral and Maxillofacial Surgery, 2008Various techniques and instruments for split-ting the ramus have been proposed to minimize therisk 3,4,8,9of damaging the IAN. To avoid complica-tions, we have used a specially designed bone cleaverto perform SSRO in more than 100 patients withmandibular prognathism.

A New Condyle Repositionable Plate for Sagittal Split Ramus Osteotomy
Journal of Craniofacial Surgery, 2010In sagittal split ramus osteotomy (SSRO) surgery, variable methods are used to maintain the proximal segment in the anatomic position during fixation to minimize early built-in relapse. However, there is still a chance of condyle malposition.In this study, a new titanium plate, which has a sliding oval hole in its distal part, was used to enable ...

Evaluation of the surgical procedure of sagittal split osteotomy of the mandibular ramus
Oral Surgery, Oral Medicine, Oral Pathology, 1974Abstract The present article introduces a statistical analysis of a surgical procedure, bilateral sagittal split osteotomy of the mandibular rami, which was performed at the University of Minnesota Hospital. A general survey of our experience with this surgical procedure in forty-one cases is also presented.

Prediction of neurosensory alterations after sagittal split ramus osteotomy
International Journal of Oral and Maxillofacial Surgery, 2013Prediction of neurosensory deficit in the lower lip and chin after sagittal split ramus osteotomy (SSRO) is challenging. This study aimed to elucidate factors related to the development and improvement of neurosensory disturbance (NSD) after SSRO with respect to surgical procedure and the anatomical and structural characteristics of the ...

Facial nerve injury as a complication of sagittal split ramus osteotomy
Journal of Oral and Maxillofacial Surgery, 1982Abstract A little-considered potential complication to the sagittal ramus split has been called to the attention of surgeons. The abnormal EMG recordings, coupled with the pattern of recovery, suggests Wallerian degeneration as the pathologic process in this patient.

Journal of Craniofacial Surgery, 2011
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.
