Platelet-rich fibrin (PRF) is an autologous biomaterial that promotes healing through the gradual release of cytokines and growth factors. This prospective, randomized, controlled, and patient-blinded study investigated whether PRF applied to the extraction socket reduces postoperative symptoms and complications. Ninety patients scheduled for mandibular third molar removal were randomized to receive PRF or no adjunct treatment prior to wound closure. Seventy-five patients completed follow-up and were included in the analysis. Postoperative outcomes including AO, infection, pain, trismus, analgesic use, and sick leave were recorded over 10 days. The incidence of AO was lower in the PRF group (3.0%) compared to the control group (11.9%), although the difference was not statistically significant. PRF treatment significantly reduced postoperative pain during the first six days. These findings suggest that while PRF may not significantly reduce AO incidence, it can contribute to improved patient comfort and recovery by decreasing early postoperative pain.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144295545","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}

Patients were randomized to receive either the drug combination or a placebo.Preoperative anxiety was assessed using the State-Trait Anxiety Inventory (STAI), Dental Anxiety Scale (DAS), and anxiety visual analogue scale (Anxiety-VAS). Post-surgery, discomfort was measured with the Self-Perception Questionnaire of Dentoalveolar Oral Surgery (QCirDental), while pain and anxiety were assessed using VAS scales. Patients also maintained a postoperative pain diary. On day 7, the Impact of Event Scale-Revised (IES-R) evaluated surgery-related PTSD symptoms.Sixty patients completed the study (30 per group), with similar demographics and surgical characteristics. Results indicated no significant difference in anxiety (STAI, DAS, Anxiety-VAS) between groups. The pre-emptive medication was similarly effective to placebo for managing anxiety, intraoperative discomfort, and postoperative pain.A stressful surgical event was observed in 13.3% of patients, leading to clinical concern or probable oral surgery-related PTSD. However, the paracetamol-codeine group did not show improved overall IES-R scores. Ultimately, a single pre-emptive dose of 500 mg paracetamol plus 7.5 mg codeine phosphate offered no additional benefits in mandibular third molar surgery.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144295544","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 inclusion of patient-specific masticatory muscle parameters such as cross-sectional area, vectors, and volume could improve implant success, but manual segmentation of these parameters is time-consuming, limiting large-scale analyses. In this study, a deep learning model was trained for automatic segmentation of eight masticatory muscles on MRI images. Forty T1-weighted MRI scans were segmented manually or via pseudo-labelling for training. Training employed 5-fold cross-validation over 1000 epochs per fold and testing was done on 10 manually segmented scans. The model achieved a mean Dice similarity coefficient (DSC) of 0.88, intersection over union (IoU) of 0.79, precision of 0.87, and recall of 0.89, demonstrating high segmentation accuracy. These results indicate the feasibility of large-scale, reproducible analyses of muscle volumes, directions, and estimated forces. By integrating these parameters into implant design and surgical planning, this method offers a step forward in developing personalized surgical strategies that could improve postoperative outcomes in mandibular reconstruction. This brings the field closer to truly individualized patient care.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144251583","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}

A method for designing a surgical template for the ideal graft volume and shape has been published previously. The aim of this study was to compare different software for the segmentation of the graft and design of the surgical template. Ten patients with unilateral cleft lip and palate were included. iPlan ENT was used for the first workflow and 3D Slicer and Blender for the second workflow. Every plan was done by two investigators. The planning time was compared between the two workflows and the two investigators. The results of the segmentation were compared by volumetric analysis. Planning with iPlan was significantly faster than 3D Slicer/Blender (P = 0.037 and P = 0.005, first and second planning by investigator 1; P = 0.017 for investigator 2). The median planning time for the experienced investigator was 297 s with iPlan and 390 s with 3D Slicer/Blender. The mean difference in graft volume was not significant (0.042 cm3). The mean ± standard deviation Hausdorff distance was 1.52 ± 0.57 mm and Dice similarity coefficient was 0.91 ± 0.02. These results show that both workflows are viable.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228067","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 aim of this study was to develop and validate a simplified scoring system for predicting excessive intraoperative blood loss (IBL) during orthognathic surgery. This retrospective cohort study included 361 patients who underwent orthognathic surgery. Factors related to excessive IBL were analysed. The candidate predictors for excessive IBL were determined by logistic regression analysis. The performance of the model was assessed through its discrimination ability and a calibration plot. Internal validation was done by bootstrap resampling technique. The regression coefficients were transformed into a scoring system. Excessive IBL occurred in 32.7% of patients (118/361). The predictive scoring system included three predictors: body mass index (score 0, 1.5, 2: overweight, normal weight, underweight), systolic blood pressure (score 0, 1: <130, ≥130 mmHg), and operative time (score 0, 2.5: ≤4, >4 h). The area under the receiver operating characteristic curve (AUROC) for discrimination ability was 0.828 (internal validation: C-statistic 0.812). Risk was then classified as low (0-2.5 points) or high (3-5.5 points). The prognostic ability of this simplified scoring system was found to be clinically acceptable for predicting excessive IBL during orthognathic surgery.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228068","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}
