Changes in computed tomography values of mandibular condyle and temporomandibular joint disc position after sagittal split ramus osteotomy

Evaluation of condylar resorption rates after orthognathic surgery in class II and III dentofacial deformities: A systematic review

“…Of these 56 articles, 50 were excluded because they did not describe the condylar resorption rate, the method of analysis used, or the validation of a new technique for 3D analysis. Thus, six articles (Kobayashi et al, 2012;Park et al, 2012;Scolozzi et al, 2013;An et al, 2014;Ueki et al, 2015;Xi et al, 2015) were selected for the qualitative analysis, and none presented sufficient data for a quantitative analysis (Fig. 1).…”

Comparison of the Horizontal Condyle Angle of the Dentulous and Edentulous Patients Using Cone Beam Computed Tomography

“…They found that the mean preoperative and postoperative HCA values were not significantly different (8). Yet, in a study using computed tomography (CT), the CT images of patients were obtained preoperatively and one year after the performance of a sagittal split ramus osteotomy, and a significant difference was found between the preoperative and postoperative HCA values (9). The discrepancy between the results of these two similar studies may be related to the different operation approaches as well as the different image acquisition intervals between the preoperative and postoperative conditions.…”

“…When incompatible results have been achieved in similar studies concerning the HCA, it is possible that the use of different patient populations may have been responsible for the difference. The HCA has been studied in maxillofacial surgery follow-up studies (8,9), analysis of TMJ internal derangement (1-3,10) and several malocclusion studies (6,(12)(13)(14). However, the HCA has not previously been studied with regard to a comparison between dentulous and edentulous patients.…”

Fixation Methods for Mandibular Advancement and Their Effects on Temporomandibular Joint: A Finite Element Analysis Study

“…Based on this finding, there is a consensus that the amount of advancement is directly proportional to the amount of relapse [8]. However, there are more RIF materials such as biological inert or resorbable materials or materials with different geometrical design, which might lead other stress distribution on the mandibular segments after fixation [5].…”

“…The stress distribution in the temporomandibular joint (TMJ) can lead to malocclusion, early relapse, and also risk of temporomandibular disorders (TMD). Thus, several navigation devices have been proposed and applied for intraoperative condylar positioning; however, there are no better long-term benefits in BSSO [5]. Only very few studies investigated the impact of BSSO on the TMJ [6,7].…”
