Summary: This study aimed to investigate the correlation between anatomical parameters of the mandible and the occurrence of a bad split in patients who underwent bilateral split sagittal ramus osteotomy (BSSRO). The results showed that certain anatomical parameters were significantly different between bad and non-bad split sides, suggesting their association with intraoperative bad split.

Summary: The study reviewed the postoperative skeletal stability in the treatment of mandibular prognathism after SSRO or IVRO, finding that SSRO showed anterior displacement and IVRO showed posterior displacement at 1-year follow-up, and both procedures presented similar relapse distances at 2-year follow-up.

Summary: This retrospective study analyzed the changes in condylar position following mandibular setback surgery with manual guidance. The results showed significant anterior-lateral-inferior movement of the condyle within 1 week after surgery, but the condyle returned to its original position over time.

Summary: This study compared the effects of two orthognathic procedures (sagittal split ramus osteotomy and intraoral vertical ramus osteotomy) on oral health, mental health, and physical health-related quality of life. The results showed that both procedures improved oral health-related quality of life, but the sagittal split ramus osteotomy group showed earlier improvement.

Summary: This study aimed to clarify the effects of three different orthognathic surgical procedures on the temporomandibular joint after mandibular setback. The results suggest that the incidence rate of postoperative TMD was higher in the conv-SSRO group in asymmetric cases, while the condylar head remained stable in the nonfix-SSRO group.

Summary: This study investigated the changes in mandibular angle, intergonial width, and ramus angulation after mandibular bilateral sagittal split ramus osteotomy (BSSRO) in patients with mandibular prognathism. The results showed that the angle and width changes may be influenced by the surgical technique and time.

Summary: This study found that the bicortical positional screws-based fixation technique can effectively maintain the space between mandibular ramus segments after surgery, without the need for revisionary surgery, in correcting facial asymmetry associated with malocclusion. Additionally, there was no significant correlation between the intersegmental gap volume and screws-and bone-related changes.

Summary: This study assessed the complications and morbidity rate after mandibular setback with bilateral intraoral vertical ramus osteotomy (IVRO). The results showed that IVRO is a safe surgical technique with low complication rate, serving as an alternative technique for mandibular setback.

Summary: This study evaluated the changes in the masseter and lateral pterygoid muscles in the prognathic mandible group after a mandibular setback by comparing the volume-to-length ratios. The results showed no significant differences in the volume-to-length ratios of the muscles after a mandibular setback, indicating that these ratios remained stable up to 1 year after the surgery.

Summary: IVRO generally presents fewer short-term and long-term surgical morbidities compared to SSRO. The SSRO group had a higher incidence of inferior alveolar nerve deficit at all follow-up time points. There were more temporomandibular joint pain at 6 weeks and 3 months postoperative in the SSRO group, along with more minor complications related to titanium plate exposure and infection.

Summary: The study aimed to investigate the relationship between the magnitude of mandibular setback and airway dimensional changes. The results showed no correlation between the two variables, suggesting that it may not be possible to predict the development of obstructive sleep apnea based on CBCT measurements of mandibular setback.

Summary: This systematic review investigated whether the presence of third molars (3Ms) during sagittal split osteotomy of the mandible increases the risk of complications. The meta-analysis results indicated that removing 3Ms before the surgery does not reduce the incidence of complications, but the presence of 3Ms may decrease the risk of nerve disorders.

Summary: The aim of this study was to assess the effectiveness of combining condylar resection with condylar neck preservation and unilateral mandibular sagittal split ramus osteotomy (SSRO) in achieving facial symmetry for patients with a unilateral condylar osteochondroma combined with dentofacial deformity and facial asymmetry. Three patients were enrolled and followed up for an average of 9.6 months. The study found that the combination of these techniques resulted in significant improvement in mandible deviation and rotation, occlusal plane canting, and facial symmetry. However, limitations of the study should be considered when interpreting the results. Overall, this study suggests that the combination of condylectomy with condylar neck preservation and unilateral mandibular SSRO can be an effective approach for achieving facial symmetry.

Summary: This study aimed to analyze the correlation between the occurrence of bad splits and the surgical tools used in bilateral sagittal split ramus osteotomy (BSSRO). The study retrospectively reviewed BSSROs performed by the same experienced surgeon and divided the patients into three groups based on the surgical instrument used: Lindemann burr, reciprocating saw, or piezosurgery. Among the 1120 BSSROs performed, 5 cases of bad fractures were observed, with 3 in the Lindemann burr group (0.8%) and 2 in the reciprocating saw group (0.5%). The study found no significant correlation between the occurrence of bad splits and patient age, gender, malocclusion type, or the type of instrument used for the osteotomy. Within the limitations of the study, the choice of osteotomy tool for BSSRO does not appear to impact the rate of bad fractures, suggesting that surgeons can use their discretion when selecting the osteotomy tool.
