The aim of this systematic review and meta-analysis was to evaluate fracture patterns, treatment strategies, and clinical outcomes of these mandible fractures, focusing on fracture location, degree of mandibular atrophy, treatment modality, and associated complications. A PRISMA-compliant systematic review was conducted. PubMed/MEDLINE, Cochrane Library, Scopus, Ovid MEDLINE, and Embase were searched (1990-2025). A single-arm meta-analysis was performed for fracture sites and complications using the Freeman-Tukey arcsine transformation. Heterogeneity and publication bias were assessed, and the robustness of the pooled estimates was evaluated by leave-one-out sensitivity analysis. Twenty-four studies encompassing 888 patients and 1279 fractures were included. The most frequent etiology was falls (≈52-55%). The mandibular body was the most affected site (pooled estimate 67%, 95% confidence interval 57-75%). Bifocal and comminuted fractures were more frequent in moderate-to-severe atrophy. The pooled overall complication rate was 19% (95% confidence interval 11-29%). Infection (3%), neurosensory disturbances (1%), and non-union (1%) were the most reported complications. Open reduction and internal fixation (ORIF) with load-bearing reconstruction plates was the predominant treatment, especially for Luhr II-III fractures; miniplates and conservative approaches were reserved for selected cases. Bone grafting was uncommon (≈1%), primarily for severe atrophy. Atrophic edentulous mandible fractures are frequently treated with load-bearing ORIF, with acceptable complication rates. A workflow-based approach integrating fracture displacement, degree of atrophy, and fracture complexity, and including the selective use of CAD/CAM planning, may support standardized, evidence-informed management.</p>","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148726637","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 purpose of this systematic review was to determine whether the systemic immune-inflammation index (SII) and systemic inflammation response index (SIRI) are reliable markers for detecting systemic inflammation in patients diagnosed with OSA, and whether they can predict its severity. Searches were conducted in the PubMed, Embase, Web of Science, Scopus, and LILACS (BVS) databases. Additional searches in the grey literature and manual searches were also performed.

During flap harvesting, the deep branch of the SCIA was discarded, and the superficial branch was dissected as the vascular pedicle; this technique is referred to as the 'simplified SCIA flap. This simplified SCIA flap was used to repair head and neck defects in 16 patients, all of whom were followed up for at least 3 months postoperatively. The superficial branch of the SCIA was successfully identified in all 16 patients. The mean pedicle length of the superficial branch of the artery was 7.2 cm (range 6.2-8.2 cm). The mean diameter of the superficial branch of the artery was 0.7 mm (range 0.6-0.9 mm), while the mean diameter of the accompanying vein was 1.2 mm (range 1.0-1.3 mm). The reconstruction was successful in 15 of the 16 patients. The remaining patient ultimately underwent reconstruction with a left radial forearm free flap. In this case, the skin paddle of the simplified SCIA flap was used as a full thickness skin graft to repair the defect in the forearm donor site. All patients completed speech and swallowing assessments during postoperative follow-up.

Methods to assess nutritional status using common blood-testing parameters include the prognostic nutritional index (PNI), hemoglobin-albumin-lymphocyte-platelet (HALP) score, and controlling nutritional status (CONUT) score. This study aimed to clarify the utility of these scores in patients with locally advanced oral cancer. A total of 106 patients with stage 3 or 4 oral squamous cell carcinoma, who underwent surgery between June 2007 and January 2020, were included. Preoperative PNI, HALP, and CONUT scores were calculated, and cut-off values were set using time-dependent receiver operating characteristic curves. The patients were divided into two arms. Cox proportional hazards analysis was used to identify the factors associated with disease-specific 5-year survival rates. Among the three preoperative scores (PNI, HALP, and CONUT), only PNI showed a significant difference between the preoperative score and disease-specific 5-year survival. The PNI score of 46.5 was set as the cut-off value, and the disease-specific 5-year survival rate was 62.0% in the PNI-low group and 76.0% in the PNI-high group (P = 0.027). In the Cox proportional hazards analysis with PNI-high/low and cancer cell differentiation as variables, the hazard ratio for PNI-high/low was 0.41 (95% confidence interval: 0.19-0.94, P = 0.034).

The aims of this study were to quantify the three-dimensional condylar remodelling postoperative by analysing immediate postoperative and 6-month computed tomography scans and to assess whether the magnitude of remodelling is associated with surgical or patient-related variables. This retrospective cohort study included 42 adults treated for isolated unilateral condylar fractures. Mandibular models were segmented and superimposed using standardized ramus-based registration. Remodelling was quantified using unsigned surface distance mapping and regional Euclidean distances across five anatomical subregions. Postoperative remodelling was observed consistently across the cohort and was statistically significant (median mean surface distance 0.60 mm; P < 0.001). However, remodelling remained modest in magnitude (mean 0.75 ± 0.53 mm; root mean square 0.94 ± 0.66 mm) with occasional focal deviations. Regional analysis demonstrated heterogeneous patterns, with greater displacement in the superior, medial, and lateral regions and smaller changes posteriorly. No statistically significant associations were identified for surgical approach, fixation plate, age, or sex, suggesting that postoperative adaptation may reflect intrinsic biological and functional processes rather than modifiable technical variables. Clinical outcomes were favourable; complications (predominantly mild and self-limiting) occurred in 28.6% of patients. Events were observed in both endoscope-assisted and open approaches. In conclusion, postoperative condylar remodelling after ORIF is significant, region-dependent, and modest in magnitude, and appears independent of surgical or demographic factors.
