The aim of this study was to document the orbital morphometry of patients with trigonocephaly compared to controls, and to classify the different morphological appearances of the orbits in trigonocephaly. Preoperative two-dimensional computed tomography scans of 15 patients with non-syndromic isolated trigonocephaly (13 male, two female; median age 11 months) and eight controls (four male, four female; median age 22 months) were digitized and analysed. Orbital height, width, and surface area (left and right) and inter-orbital distance were measured. For the trigonocephaly patients, orbital morphology was classified into various shapes (rhomboid, kidney bean, teardrop, oval, pear, pentagon, hexagon, and triangular) and assessed across three age groups. There was no significant difference in any of the morphometric measurements between the trigonocephaly and control groups. In the control group, inter-orbital distance was significantly and strongly correlated with orbital width (left, r = 0.799; right, r = 0.712), height (right, r = 0.736), and surface area (left, r = 0.903; right, r = 0.853) (all P < 0.05), while no significant correlation was observed between inter-orbital distance and the orbital measurements in the trigonocephaly group. The most commonly observed orbital shapes by age group were kidney bean in the <12 months age group and pear and oval in the 12 to <36 months age group. The study findings could assist craniofacial and reconstructive surgeons in selecting the surgical technique needed to obtain as near to normal orbital morphology and function as possible.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148803348","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 total of 117 patients were classified into a model surgery (MS) group (n = 32) and a VSP group (n = 85). Sliding genioplasty frequency was compared between groups, and subgroup analysis was performed according to preoperative menton deviation. In patients with severe menton deviation (≥4 mm), postoperative transverse skeletal and soft-tissue symmetry was additionally assessed using cone-beam computed tomography. Overall, there was slight evidence that adjunctive sliding genioplasty was performed less frequently in the VSP group than in the MS group (18% vs 34%, P = 0.079). In patients with severe menton deviation, the frequency was significantly lower in the VSP group (27% vs 82%, P = 0.003). In this subgroup, both VSP and MS groups showed significant postoperative improvement in transverse facial symmetry, with no significant intergroup differences in postoperative menton deviation (P = 0.17), soft-tissue pogonion deviation (P = 0.099), transverse surgical change at the bony menton (P = 0.52) or soft-tissue pogonion (P = 0.86), or the soft-to-hard tissue movement ratio (P = 0.20). VSP was associated with less frequent adjunctive sliding genioplasty in patients with severe preoperative menton deviation, while postoperative cone-beam computed tomography-based transverse skeletal and soft-tissue symmetry remained comparable between groups.

Patients undergoing bilateral sagittal split and/or Le Fort I osteotomies, or treatment for mandible, maxilla, or zygoma fractures at four hospitals were included. Eligible participants (n = 230) were randomly assigned to receive titanium (KLS Martin) or biodegradable (Inion CPS) plates and screws (1:1).

All non-duplicate studies were screened against the inclusion criteria to determine eligibility. Study characteristics and outcomes data were extracted from the included studies. The pooled incidence of SMG involvement per OSCC case and per SMG was estimated by random-effects meta-analysis; subgroup analyses according to study design were also performed. Publication bias was assessed by funnel plot. A descriptive analysis of the prognostic impact of SMG involvement on OSCC was performed. Overall, 32 studies were included, involving 6495 OSCC patients who underwent 6790 SMG removals. The pooled incidence of SMG involvement per OSCC patient was 0.021 (95% confidence interval 0.015-0.028) and per SMG was 0.020 (95% confidence interval 0.014-0.027). Although involvement of the SMG impacts the overall prognosis, the number of studies providing survival data is limited. This review identified a low incidence of SMG involvement in OSCC, and when present, this was primarily due to direct tumour invasion or extracapsular spread. While data on the prognostic significance of SMG involvement remain limited, existing evidence suggests that selective preservation of the SMG may be oncologically safe in OSCC.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148803762","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}

However, the extent of ENE (minor vs major), is not a part of the decision-making process for the treatment of head and neck cancers. The aim of this study was to investigate its effect on prognosis in oral cavity squamous cell carcinoma (OCSCC). A retrospective analysis was conducted of adult patients treated surgically for OCSCC at a a university-affiliated tertiary care centre between the years 2002 and 2022, who had ENE on final pathology. Major ENE beyond the lymph node capsule was considered >2 mm. Overall survival (OS), disease-free survival (DFS), and ENE extent association with other factors were analysed. Out of a total of 349 patients treated surgically for OCSCC during the study period, 101 (28.9%) were node-positive: 47 (13.5%) had ENE, of whom 16 (4.6%) had minor ENE, and 31 (8.9%) had major ENE (>2 mm). DFS was significantly longer in the minor ENE group when compared to the major ENE group, (P = 0.016), while OS was not (P = 0.34). On multivariate analysis, the only variable that was significantly associated with DFS was major ENE when compared to minor ENE, with a hazard ratio of 5.47 (95% confidence interval CI 1.19-25.08%, P = 0.02). The extent of ENE seems to be an important prognostic factor in OCSCC.

This study evaluated how different visualization methods impact the efficiency and interpretability of real-time feedback during orbital reconstruction. A standardized in-vitro setup was used to simulate orbital reconstructions by six surgeons of varying experience levels. Each surgeon performed implant positioning tasks using six different visualization modes, starting from three predefined misaligned positions. Interpretation accuracy and time to correct implant positioning were recorded. Visualization methods varied in the presence of computed tomography (CT) images, visualization of three-dimensional (3D) models, and use of implant-to-target distance visualization (distance mapping). Across a total of 108 reconstructions, no statistically significant differences in positioning time or interpretation accuracy were found between visualization methods. However, surgeon feedback revealed strong preferences: anatomical CT data and additional coronal view at the ledge improved spatial understanding, while views relying solely on 3D models or instrument orientation were seen as less intuitive. Notably, surgeons reported a consistent two-step strategy: initially 3D views were used for initial spatial alignment, followed by two-dimensional slices for precise adjustments. These findings suggest that while performance metrics may not differ across visualization modes, surgeon usability and interpretability are critical for clinical implementation. Future development of a clinically viable navigation workflow should include real-time feedback with both anatomical context and tailored visual support to promote more intuitive navigation in orbital surgery.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148766060","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}

Preoperative PCS, Graded Chronic Pain Scale (GCPS), and Jaw Functional Limitation Scale-8 (JFLS-8) were recorded and compared with postoperative GCPS and JFLS-8 scores at 3-6 months (short-term) and 12-18 months (medium-term). The median preoperative PCS score was 17.5. Higher PCS scores were significantly associated with higher postoperative GCPS scores at short- and long-term follow-up (P = 0.031 and 0.048) and with higher (worse) short-term JFLS-8 scores (P = 0.039), though not at medium-term follow-up. GCPS correlated significantly with all PCS subscores in the short term, but only helplessness remained significant in medium term. JFLS-8 showed significant correlation with rumination and helplessness short term only. These findings suggest that PCS, particularly the helplessness component, is associated with pain and function outcomes after TMJ surgery and may help predict recovery.
