This study compares the outcomes of the mandible-first approach using an intermediate splint and manually bent osteosynthesis plates with the maxilla-first approach utilizing patient-specific osteosynthesis fixation in bimaxillary orthognathic surgery. This multi-centre randomized controlled trial included 88 patients, with 77 completing the study. Patients were randomly assigned to either the 'mandible-first' group (mandible-first with an intermediate splint) or the 'maxilla-first with PSO' group (maxilla-first with patient-specific osteosynthesis). Postoperative evaluation using cone beam computed tomography images showed significantly lower deviations from the preoperative plan in the maxilla-first with PSO group compared to the mandible-first group, for anteroposterior (median 1.0 mm vs 1.8 mm, P = 0.008) and left/right translations (median 0.4 mm vs 0.8 mm, P = 0.003), and yaw rotation (median 0.5° vs 1.0°, P = 0.013). Regarding clinical accuracy (categorized as optimal, good, or suboptimal), 59.5% of the patients in the maxilla-first with PSO group had an optimal or good result compared to 17.5% in the mandible-first group. The study findings suggest the maxilla-first PSO approach offers enhanced accuracy, supporting its adoption in orthognathic surgery for better surgical outcomes.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143257650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When non-invasive treatments fail, minimally invasive procedures like TMJ arthrocentesis with saline and hyaluronic acid (HA) injections are commonly used. Orthobiologics, including platelet-rich plasma (PRP) and cell-derived products, have gained attention for their potential to enhance tissue healing. This review aimed to compare the outcomes of orthobiologic injections with HA injections following arthrocentesis in TMJ-OA treatment. A systematic search, following PRISMA guidelines, identified nine studies (403 patients). Risk of bias was assessed using the Cochrane Risk of Bias Tool. PRP and cell-derived products showed potential benefits in reducing TMJ pain and improving maximum mouth opening (MMO). However, three of four studies comparing PRP with HA found no significant difference between the two. In contrast, cell-derived orthobiologics demonstrated significantly greater improvements in TMJ pain and MMO compared to HA. Risk of bias varied, with some studies showing moderate to high levels. This review highlights the potential but inconsistent benefits of orthobiologics in treating TMJ-OA. While cell-derived orthobiologics appear promising, PRP did not demonstrate superiority over HA. Further high-quality studies are needed to validate these findings.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143076518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The osteotomy lines were divided into original sagittal split ramus (SSRO), short lingual (SLO), and short buccal (SBO) osteotomies. Skeletal stability was evaluated, and TMDs were assessed preoperatively. Overall, 135 patients (270 TMJs) (87 female, 48 male; mean age 23.7 ± 7.8 years) were included. Mean mandibular setback was 6.2 ± 2.9 mm. Skeletal stability was observed in all patients. TMD were recorded in 47 joints (17.4%) preoperatively and 15 joints (5.6%) postoperatively. When TMD were compared between joints with and without plate fixation, preoperative TMD was found to be improved in non-fixed joints (P = 0.004). On multivariate analysis, segment fixation (P = 0.040), the osteotomy line (SBO vs SLO/SSRO, P = 0.043), and preoperative TMD (P = 0.030) were associated with postoperative TMD.

Recently, ultrasound-based 3D bone modelling has attracted much attention, and its accuracy has been studied for the femur, tibia, and spine. The use of ultrasound allows data for bone surface to be acquired non-invasively and without radiation. Freehand 3D ultrasound of the bone surface can be roughly divided into two steps: segmentation of the bone surface from two-dimensional (2D) ultrasound images and 3D reconstruction of the bone surface using the segmented images. The aim of this study was to develop an automatic algorithm to segment the midface bone surface from 2D ultrasound images based on deep learning methods. Six deep learning networks were trained (nnU-Net, U-Net, ConvNeXt, Mask2Former, SegFormer, and DDRNet). The performance of the algorithms was compared with that of the ground truth and evaluated by Dice coefficient (DC), intersection over union (IoU), 95th percentile Hausdorff distance (HD95), average symmetric surface distance (ASSD), precision, recall, and time. nnU-Net yielded the highest DC of 89.3% ± 13.6% and the lowest ASSD of 0.11 ± 0.40 mm. This study showed that nnU-Net can automatically and effectively segment the midfacial bone surface from 2D ultrasound images.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143070512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The facial data of 47 patients who underwent maxillary resection due to tumors were captured using stereophotogrammetry. Facial asymmetry was measured using a landmark-independent method and assessed with a Likert scale. Facial asymmetry was classified into three grades (I-III) based on visual perception. Statistically significant differences (P < 0.001) were found in the asymmetry of the suborbital, zygomatic, buccal, and superolabial areas among the different visual perception categories, and the symmetry of these areas significantly influenced the visual perception (P < 0.001). The maxillary defect magnitude significantly influenced facial asymmetry perception (P < 0.001). Substantial statistical variations (P < 0.001) in the asymmetry of four facial areas, excluding the masseteric and nasal areas, across the different classes of maxillary defect were noted. Maxillary defects significantly affect the midface soft tissue symmetry. Reconstruction should focus on sufficient soft tissue support in the zygomatic, buccal, suborbital, and superolabial areas. Corrective measures are generally unnecessary for grade I asymmetry. For grade II asymmetry, reconstruction can be decided individually. For grade III asymmetry, reconstruction is essential.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143054680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oral examination revealed an indurated tumour of 10 mm, extending from the lower labial mucosa to the labial commissure. The lesion was resected with a surgical margin of >10 mm from the induration, under general anaesthesia. The full-thickness labial mucosa to the cheek, with overlying skin and labial commissure, was resected. Pathologically, spindle-shaped cells with pale eosinophilic cytoplasm were observed. Most of the tumour cells exhibited mild to moderate nuclear atypia and were positive for α-smooth muscle actin and CD34 on immunohistochemistry. Based on these findings, a pathological diagnosis of DFSP was made. The postoperative course was uneventful, and no recurrence was observed for over a year. Oral DFSP is extremely rare and challenging to diagnose, and DFSP of the labial mucosa, as reported here, is exceptionally rare.

Three-dimensional cephalometric characteristics of skeletal mandibular retrusion were analysed using computed tomography scans from 15 patients with OA and 15 without OA. Mandibular, dental, and condylar-related factors were evaluated. Severity was scored by counting findings of cysts, erosion, atrophy, osteophytes, and sclerosis (score of 1 for the presence of each). The OA group was further divided into mild and moderate OA according to the total severity score of both condyles. The mean condylar volume was significantly lower in OA (851.1 mm3) than in non-OA (1151.3 mm3) (P < 0.001). A decrease in volume was significantly correlated with the number of radiographic OA findings (P = 0.012). Findings seen in mild OA were mostly cysts and erosion, while all findings were identified in moderate OA. The measured factors did not differ significantly between the mild OA and non-OA groups, whereas many mandible-related factors differed significantly between the moderate OA and non-OA groups. A significantly lower volume of the condyle was observed in moderate OA compared to non-OA (P < 0.001), suggesting that the appearance of atrophy, osteophytes, and sclerosis worsened OA from mild to moderate, and correspondingly, mandibular retrusion became apparent.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143042835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
