Patient records from University Hospitals Leuven were screened for CBCT related to implant surgery cases with nerve injuries. CBCT scans were imported into Virtual Patient Creator for canal segmentation and 3D model generation. Two oral radiologists compared the AI-segmented canals with respective CBCT images. Five observers then performed canal identification and injury detection (present/absent) and reported their confidence level on a five-point Likert scale. Ten patient cases were assessed (eight female, two male; age 49-81 years). The AI-based tool enabled clear visualization of bilateral MIC in both pre- and postoperative images, revealing implant-canal relationships consistent with recorded post-implant pain or neural disturbance. For preoperative assessment, the AI-based tool significantly improved incisive canal detection (by 25%; P = 0.025) and observer confidence (by 8%; P = 0.038). The AI-based tool proved to be clinically useful to enable bilateral MIC visualization on CBCT images. Through canal segmentation with integrated 3D modelling, preoperative canal detection and the experts' confidence level were significantly improved.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660113","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}

Three ML models were used for the discrimination of skeletal discrepancy: random forest, AdaBoost, and multi-layer perceptron. Each model was evaluated by receiver operating characteristic curve and calculating the area under the curve (AUC). Principal component analysis was conducted to evaluate shape variability. The AUCs for Class II and III patients ranged from 0.91 to 0.95. Random forest achieved the highest accuracy for sagittal classification (88.5% for Class II, 95.5% for Class III). Multi-layer perceptron exhibited the best performance for vertical classification (accuracy of 78.8% for hypodivergent, 86.2% for hyperdivergent). Six principal components explained 94.0% of facial morphology variation. ML methods show promise for assisting in the discrimination of sagittal and vertical skeletal discrepancies based on 3D facial scans. 3D facial soft tissue features appear to be suitable for the discrimination of skeletal discrepancies in most cases.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660199","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}

This study was performed to evaluate the surgical burden and direct healthcare costs of four UCLP surgical protocols at Erasmus University Medical Centre, Rotterdam, to guide optimal protocol selection. This retrospective cohort study included UCLP patients treated during 1990-2024. The patients were categorized into groups based on the hard palate closure timing: Oslo protocol (OP), one-stage palatoplasty protocol (OSPP), early delayed hard palate closure protocol (E-DHPCP), and late delayed hard palate closure protocol (L-DHPCP). Primary surgeries were analysed for operative duration (OD) and length of hospital stay (LOS), and their associated costs were estimated. Overall, 331 patients were included. Mean cumulative OD was significantly shorter for L-DHPCP and OSPP when compared to E-DHPCP and OP, while mean cumulative LOS was significantly longer for E-DHPCP compared to the other protocols. Mean cumulative OD was 408, 465, 425, and 507 min, and mean cumulative LOS was 3.95, 4.84, 4.07, and 4.11 nights for L-DHPCP, E-DHPCP, OSPP, and OP, respectively. Mean total costs were estimated at €17,858, €20,791, €18,545, and €21,158, respectively. L-DHPCP and OSPP demonstrated the lowest surgical burden and direct healthcare costs, although differences were minor. Therefore, the choice between these four surgical protocols should continue to be based on clinical outcomes, rather than differences in burden and costs.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639870","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 study included 127 female patients (mean age 52.3 years). None of them had undergone prior occlusal splint therapy. The pain reduction (visual analogue scale) at 12 months post-treatment was the primary outcome variable, while maximum inter-incisal opening (MIO) at all follow-ups and pain at 1 and 6 months of follow-up were secondary outcome variables. All treatment groups showed significant improvements in pain and MIO at all postoperative follow-ups compared to baseline (P < 0.001). iPRF and HA resulted in significantly better pain relief than AO at all follow-ups (P < 0.01). There was no significant difference in pain alleviation between iPRF and HA. No differences were observed among the three groups in jaw mobility (MIO) at any follow-up. Since iPRF did not provide additional benefits over HA, the two treatments may be considered as alternatives, depending on cost considerations.

Two sets of cone beam computed tomography scans were included: one with segmentations of complete mandibles and the other with pre- and postoperative segmentations of the mandibular rami. Two convolutional neural networks predicted a segmentation of the mandible and its ramus segments. Each preoperative ramus segment was registered to the postoperative mandible, and the pre- and postoperative condylar volumes were determined. For validation, the agreement between the fully automatic assessment and a validated semi-automated method was calculated using mean absolute differences (MAD) and intraclass correlation coefficients (ICC). Forty condyles in 20 patients (16 female, four male; mean age 27.6 years) with maxillomandibular retrognathia, who underwent bimaxillary surgery, were assessed. A small difference in condylar volume change measurements was observed between the two methods (MAD 2.7%); the ICC, at 0.993, was excellent. The fully automatic method was considerably faster than the semi-automated method (3 min vs 30 min) and demonstrated high precision and excellent reliability for quantifying condylar volume changes. A fast and reliable assessment of condylar changes can identify volume changes sooner, leading to improved personalized patient care.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143588687","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 majority of the gnathic intraosseous lipomas (32/39, 82%) occurred in the mandible. The posterior region was more frequently affected than the anterior region (24/39, 62%), in both maxilla and mandible cases (86% and 56%, respectively). Most lesions presented as a well-defined radiolucency; however, the lesions may appear multilocular and may range from radiolucent to mixed radiolucent-radiopaque to 'ground glass'. Surgical excision or enucleation was the most common treatment. Intraosseous spindle cell lipomas are exceedingly rare. Based on the available evidence, surgical excision is the recommended treatment with a favorable prognosis and low recurrence rate.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532271","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}
