Condylar reconstruction by oblique sliding vertical–ramus osteotomy

Condylar Hyperplasia and Facial Asymmetry: Report of Five Cases

“…This method is considered useful particularly to treat vertical discrepancies associated with the hyperplastic or hypoplastic condyle. Condylar reconstruction by oblique sliding vertical-ramus osteotomy in cases of condylar hyperplasia after condylectomy has been described [32]. Wolford [26,27] studied and showed that patients with active condylar hyperplasia, treated with high condylectomy, articular disc repositioning, and orthognathic surgery of single or both jaws have stable, predictable outcomes compared with those treated with orthognathic surgery alone.…”

Ramus Condyle Unit Reconstruction Using Vertical Ramus Osteotomy in Temporomandibular Joint Ankylosis

“…Vertical ramus osteotomy has been previously used in animal and human studies as a good alternative to reconstruct a neocondyle as a pedicle graft with satisfactory TMJ function [10][11][12][13][14]. Vertical ramus osteotomy is indicated for the correction of mandibular prognathism, mandibular asymmetry, distraction osteogenesis of the mandible and post-traumatic reconstruction.…”

“…costochondral, clavicular) the use of the posterior border of the mandible as a pedicled graft can be performed safely and easily [13]. The posterior ramus border is attached to the medial pterygoid muscle, which can supply enough blood to prevent bone resorption/ necrosis.…”

“…When postoperative CT scan was done at 12 months follow-up, there was well-maintained intra-articular space and the graft had taken the shape of the condyle. Martinez-Lage [13] pointed out in their study that mild to moderate displacement of the bone fragments permit enough bone in contact to stimulate the formation of a fracture callus and to restore continuity by forming a new ramus that is able to resist mastication forces. In the present study, complete bony union occurred between the grafts and the ramus in all the patients.…”

“…Vertical ramus osteotomy (VRO) for reconstruction of the RCU in TMJ Ankylosis corrects the function, morphology of the orofacial structure, is safe, effective and less invasive [13,14]. Thus exploration of two surgical sites, donor site morbidity and graft resorption are readily avoided [12] Taking these advantages into consideration a study was carried out in the Oral and Maxillofacial Surgery Department of our institution on ten patients with TMJ Ankylosis with the aim to evaluate the feasibility of VRO on the posterior border of the mandibular ramus for reconstruction of the RCU.…”
