Patients were categorized based on treatment approach (through traumatic laceration, bicoronal, or endoscopic transorbital). For the comparative analysis, cases with associated maxillofacial fractures or cerebrospinal fluid (CSF) leakage were excluded.Results: Out of 133 patients, 35 underwent surgery, with 6 patients treated using the endoscopic transorbital approach. This group of patients treated with the transorbital endoscopic approach demonstrated significantly shorter operative times compared to the bicoronal approach (mean 102 vs. 168 min, p = 0.021). They also had only minor complications, including temporary hypoesthesia and one transient ptosis. One patient had a minimal residual defect. The technique has been concluded to require endoscopic expertise.Conclusions: The endoscopic transorbital approach is a safe, minimally invasive alternative to the bicoronal approach for selected anterior wall frontal sinus fractures. Proper patient selection and surgical experience are essential to achieving favorable outcomes. Studies with longer follow-up are required to assess potential late complications, such as the development of mucoceles.","PeriodicalId":46447,"journal":{"name":"Craniomaxillofacial Trauma & Reconstruction","volume":"18 3","pages":"41"},"PeriodicalIF":0.4,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12468538/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145186459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional fixation methods may present biomechanical and aesthetic limitations.Objective: This study introduces and evaluates a novel Anatomical Chin Plate (ACP), designed to enhance mechanical performance and facial aesthetics compared to the conventional chin plate (CP).Methods: A three-dimensional finite element analysis (FEA) was conducted to compare stress distribution in ACP and CP models under a standardized oblique load of 60 N, simulating muscle forces from the mentalis and digastric muscles. Plates were modeled using Blender and analyzed using ANSYS software 2025 r2. Mechanical behavior was assessed based on von Mises stress, concentration sites, and potential for plastic deformation or fatigue failure.Results: The ACP demonstrated a significantly lower maximum von Mises stress (77.19 MPa) compared to the CP (398.48 MPa). Stress distribution in the ACP was homogeneous, particularly around the lateral fixation holes, while the CP exhibited concentrated stress between central screw holes. These findings indicate that the anatomical geometry of the ACP enhances load dispersion, reduces critical stress concentrations, and minimizes fatigue risk.Conclusions: The ACP design offers superior biomechanical behavior and improved aesthetic potential for genioplasty procedures. Its optimized shape allows for better integration with facial anatomy while providing stable fixation. Further studies are recommended to validate in vitro performance and explore clinical applicability in advanced genioplasty and complex osteotomies.","PeriodicalId":46447,"journal":{"name":"Craniomaxillofacial Trauma & Reconstruction","volume":"18 3","pages":"42"},"PeriodicalIF":0.4,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12469031/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145187306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, we trained a deep neural network using CT-based segmentations of the mandible, cranium, and inferior alveolar nerve as ground truth. A dataset of 100 patients with paired CT and MRI scans was collected. MRI scans were resampled to the voxel size of CT, and corresponding CT segmentations were rigidly aligned to MRI. The model was trained on 80 cases and evaluated on 20 cases using Dice similarity coefficient, Intersection over Union (IoU), precision, and recall. The network achieved a mean Dice of 0.86 (SD ± 0.03), IoU of 0.76 (SD ± 0.05), and both precision and recall of 0.86 (SD ± 0.05). Surface deviation analysis between CT- and MRI-derived bone models showed a median deviation of 0.21 mm (IQR 0.05) for the mandible and 0.30 mm (IQR 0.05) for the cranium.

Twenty-four adult male patients with AUD and isolated facial fractures requiring surgery were enrolled. They were assigned to either an intervention group (n = 12) receiving MTAA-oral alcohol at 0.5 g/kg/day for two weeks-or a control group (n = 12) undergoing complete abstinence. Outcomes were assessed over six weeks, including stress (Zung Self-Rating Depression Scale), quality of life (Oral Health Impact Profile-14), soft tissue healing (Landry's Index), and hard tissue healing (Moed's Scale, serum osteocalcin). The MTAA group showed significantly reduced stress and improved quality of life (p < 0.001). Healing outcomes were comparable between groups, with no significant differences in soft tissue indices, osteocalcin levels, or radiographic scores. MTAA appears to be a safe and effective strategy to manage AWS-related distress and improve postoperative recovery, offering a practical alternative to strict abstinence in the surgical management of patients with AUD.","PeriodicalId":46447,"journal":{"name":"Craniomaxillofacial Trauma & Reconstruction","volume":"18 3","pages":"37"},"PeriodicalIF":0.4,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12452396/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145132234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyzed 32 cases of pedicled auricular avulsion reported in 16 articles, focusing on patient demographics, injury mechanisms, pedicle characteristics, venous congestion, and postoperative management. Venous congestion occurred in 11 patients, with a significantly higher risk in narrower pedicles (mean width 9.82 mm; 95% CI: 4.75-14.89; p = 0.025). Prophylactic heparin significantly reduced this risk (p = 0.007). Other interventions-leech therapy and hyperbaric oxygen-lacked sufficient data for firm conclusions. Most cases achieved graft survival; necrosis occurred in some, and only two patients required additional surgery. Non-microvascular techniques appear to be a viable alternative to microvascular reimplantation, with similar results and potentially fewer complications. Venous congestion remains the main challenge, requiring active management and hospitalization for monitoring. Limited case series and publication bias still hinder the development of standardized guidelines.","PeriodicalId":46447,"journal":{"name":"Craniomaxillofacial Trauma & Reconstruction","volume":"18 3","pages":"36"},"PeriodicalIF":0.4,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12452382/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145132237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the urgent need for validated educational tools that surpass traditional learning models, this multicenter study developed and validated a novel synthetic advanced simulation model for the reconstruction of these fractures. The model integrates platinum-cured silicones and 3D-printed bony structures with prefabricated fractures, accurately replicating the anatomy and tactile properties of soft and hard tissues, including simulated herniation of orbital contents. To our knowledge, it is the only available synthetic model combining both tissue types for this training. Ten participants (faculty and residents) completed simulated procedures. Technical performance was assessed using a hand motion tracking system, the global OSATS (Objective Structured Assessment of Technical Skills) scale, and a task-specific error measurement (Specific Fault Measurement, SFM) scale. Statistically significant differences (p = 0.021) were observed in operative time and error count between novices and experts, confirming the model's construct validity. Faculty completed the surgery in significantly less time (mean 18.16 min vs. 37.01 min for residents) and made fewer errors (mean 12.25 vs. 53.25). Face and content validity were strongly supported by participant surveys, with 100% stating they would use the simulator to practice before real surgery. A strong inverse correlation (r = -0.786, p = 0.021) between OSATS and SFM scores demonstrated concurrent validity.

The general consensus is that post-traumatic primary deformity repair should aim to restore the premorbid volume, shape, and cosmesis of the orbitozygomatic complex (OZC). This study aims to utilise novel three-dimensional (3D) printed patient-specific moulds to intraoperatively fabricate enophthalmos wedges and onlays using polymethylmethacrylate (PMMA) bone cement to reconstruct the OZC.Methods: A total of seven patients underwent digital surgical planning using Freeform software to virtually correct orbitozygomatic complex deformities guided by a design algorithm. Three-dimensionally printed nylon patient-specific moulds were used intraoperatively to fabricate enophthalmos wedges and/or onlays using an industry-standard PMMA bone cement. Clinical examination and application of the proposed design algorithm determined that enophthalmos wedges were indicated for four patients, with one also requiring an onlay; and periorbital onlays were required for the three remaining patients.Results: Hertel exophthalmometry at a mean follow-up of 19.1 months demonstrated good outcomes in the correction of post-traumatic enophthalmos and hypoglobus and with patients reporting good subjective cosmetic results. Patients 5 and 7 had follow-up three-dimensional computed tomography (3D-CT) to confirm correct placement.Conclusion: The use of patient-specific PMMA wedges and onlays, fabricated intraoperatively with the aid of 3D-printed moulds, offers a reliable and effective approach for correcting post-traumatic enophthalmos and hypoglobus. This method allows for the restoration of orbital volume and anatomical contours, addressing both functional and aesthetic concerns.
