These patient-specific implants (PSI), which are now being widely used for mandibular reconstruction surgery for oral cancer, have improved the efficiency of surgery and have allowed more precise execution of the preoperative plan. The present study compared the efficacy of PSI with conventional reconstruction plates (CR) requiring bending for mandibular reconstruction following segmental and hemimandibular resection in patients with an oral malignancy who underwent free-flap reconstruction including a reconstruction or bridging plate without bone. Thirty-nine patients from the previous 8 years were analyzed, including 21 with PSI-based reconstructions and 18 with CR. The median follow-up period was 1322 days (range 91-3225). Soft-tissue reconstruction was performed using an anterolateral thigh flap in all cases. The PSI group demonstrated a significantly shorter operative time (P = 0.0002), reduced intraoperative blood loss (P = 0.0039), and no instances of plate-related infection compared to three cases in the CR group. These findings highlighted the advantages of PSI for improving surgical efficiency and minimizing the burden on the patient, particularly in patients with free-flap mandibular reconstructions without microvascular bone flaps, such as a fibular or iliac crest flap.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149043015","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 treated with 20% 5-ALA and 635 nm laser light at 100 J/cm2 every 1-3 weeks, followed by at least 1 year of follow-up. Among the 94 patients, 36.2% achieved a complete response, with an overall response rate of 92.6%. Factors predicting better short-term efficacy included good oral hygiene (P = 0.042), no baseline pain (P = 0.025), single lesions (P = 0.025), lesion size <2 cm2 (P = 0.002), and the use of topical incubation (P = 0.004), particularly for ≥2.5 h (P = 0.002). With a median follow-up of 38 months, the cumulative recurrence rates were 33.0% at 1 year, 42.6% at 2 years, and the cumulative malignant transformation (MT) rates were 1.1% at 1 year, 10.6% at 2 years, and 25.5% at 5 years. Cox regression analysis identified female gender as an independent risk factor for recurrence. Hyperglycemia and lack of initial clinical response were independent predictors for MT. After 1:1 propensity score matching based on gender, age, and oral epithelial dysplasia grade, 84 pairs of patients were included in the PDT group and the control group. Kaplan-Meier survival analysis revealed that the matched control group showed faster MT (P = 0.041), especially among patients with lesions in high-risk areas (P = 0.001). The study indicates that 5-ALA-PDT is an effective treatment for OPMDs and may protect against malignant progression.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149043042","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 ambispective cohort study evaluated the relationship between three-dimensional PNS displacement and postoperative changes in upper airway dimensions and sleep quality in 33 adults with skeletal class III malocclusion who underwent Le Fort I osteotomy and bilateral sagittal split ramus osteotomy. Cone-beam computed tomography with voxel-based superimposition and level III portable polysomnography (screening tool) were performed preoperatively and postoperatively. Upper airway volumes were segmented into nasopharyngeal, oropharyngeal, and hypopharyngeal regions. Mean PNS displacement was 3.71 ± 1.38 mm anteriorly and 2.12 ± 1.83 mm superiorly. Nasopharyngeal volume decreased significantly from T0 to T1 by a mean of 555 mm3 (∼7% from baseline). Multivariable linear regression further revealed that superior PNS displacement was significantly associated with this reduction (β = -453 mm3/mm, P = 0.001). This reduction did not result in clinically significant deterioration of objective sleep parameters. Pittsburgh Sleep Quality Index scores improved significantly postoperatively (P = 0.040). Oropharyngeal, hypopharyngeal, and total airway volumes showed no significant changes. Superior PNS displacement causes a statistically significant but functionally compensated nasopharyngeal volume reduction, suggesting that controlled posterior maxillary impaction may not adversely affect sleep quality in patients with no significant preoperative obstructive sleep apnea.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149066934","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}

Pooled 5-year overall survival following surgical salvage is approximately 40%, yet patient selection remains inconsistently structured and the reconstructive strategy for the previously treated field is inadequately addressed in existing reviews. This narrative review was performed to synthesize the current evidence on salvage surgery for recurrent OCSCC with emphasis on three insufficiently addressed domains: (1) prognostic stratification for surgical candidacy integrating disease-free interval, prior treatment intensity, recurrence stage, and performance status; (2) reconstructive feasibility assessment in the previously operated and irradiated field, including recipient vessel strategy and flap selection; and (3) integration of re-irradiation and emerging systemic therapies into salvage treatment planning. An expert-informed decision framework is proposed comprising four sequential assessment gates - oncological resectability, prognostic stratification, reconstructive feasibility, and adjuvant therapy sequencing - that links patient-level factors to surgical candidacy, reconstructive planning, and multimodality treatment. This framework groups patients into favorable, intermediate, and unfavorable salvage-risk categories to structure multidisciplinary discussion and management planning in a setting where validated decision tools remain limited. This review provides the surgical oncologist with a structured, evidence-informed approach to one of the most consequential treatment decisions in head and neck oncology.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149032305","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}

Although arthroscopic approaches are widely used for minimally invasive management of TMJ disorders, reproducible techniques for arthroscopic disc removal remain limited. This technical note describes the feasibility of a two-portal arthroscopic subtotal meniscectomy for non-repairable TMJ disc perforation. The procedure is performed using a standard posterolateral viewing portal and a single anterolateral working portal. Disc release is achieved sequentially using radiofrequency instrumentation, followed by removal of released disc fragments with arthroscopic grasping forceps through the same working cannula. This repetitive process allows controlled removal of non-functional disc tissue under continuous visualization while minimizing capsular trauma. Due to anatomical constraints inherent to a two-portal approach, a thin residual disc remnant may persist in the medial or posteromedial region and is considered functionally irrelevant. This technique is intended for selected cases with clearly non-repairable disc perforation and aims to simplify portal placement while expanding the arthroscopic surgical options for advanced TMJ internal derangement.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149042677","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}

For each model, nine digitally manipulated profile images were generated from -8° to +8° relative to baseline and assessed by orthodontists, oral and maxillofacial surgeons (OMFS), and laypersons (n = 72). Two multimodal artificial intelligence systems, ChatGPT-4.0 and Gemini 1.5 Pro, independently generated attractiveness scores to provide an exploratory benchmark for human-AI agreement. The selected models showed distinct sagittal response patterns. For the female model, attractiveness ratings peaked within a mild retrusive range (-2° to -4°), whereas ratings for the male model increased with greater sagittal projection. Significant intergroup differences were observed at selected sagittal positions, with orthodontists generally showing narrower esthetic tolerance. Profile-based surgical recommendations differed significantly for the male model (P < 0.001), with OMFS specialists recommending intervention most frequently, while no significant overall group difference was found for the female model. Human-AI agreement was model-dependent: Gemini showed closer alignment with human ratings for the female model, whereas ChatGPT-4.0 aligned more closely with human ratings for the male model. Both AI systems declined to provide surgical recommendations because of built-in ethical restrictions. Within the limitations of a two-model, profile-based design, sagittal esthetic perception appeared to vary according to model sex, evaluator background, and AI system. These findings should be interpreted as model-specific and exploratory rather than as generalizable sex-based esthetic norms.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149003189","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}

Fourteen were excluded (seven initial implementation phase; seven class III deformity), leaving 36 patients for final analysis. Patients were chronologically allocated into a control group (pre-implementation) and a study group (post-implementation). Intraoperative cone-beam computed tomography (CBCT) with cranial-base superimposition was used to assess surgical accuracy. The primary outcome was skeletal movement accuracy, defined as the discrepancy between planned 3D-VSP and intraoperative outcomes, assessed by superimposition of VSP and CBCT datasets. Secondary outcomes included translational and rotational deviations, landmark-specific discrepancies (mm) at the mandibular B-point, gonion, and ramus, and corticotomy angle deviation (degrees) to evaluate osteotomy accuracy. The guide-assisted group demonstrated significantly improved B-point accuracy (P = 0.001) and corticotomy angle precision (P = 0.012). Threshold-based accuracy outcomes also favored the guide-assisted group, while operative time did not differ significantly between groups.
