This prospective study evaluated the predictive accuracy of CASST and its concordance with clinical decision-making in patients undergoing major oral cancer surgery. A secondary objective was to describe short-term postoperative airway complications stratified by CASST category. All patients undergoing major oral cancer resections at a tertiary care centre between September 2021 and January 2024 were enrolled and followed prospectively. CASST scores were computed preoperatively but did not guide airway management decisions. Among 258 patients, 126 (48.8%) underwent elective tracheostomy. Only 31.7% of these procedures aligned with CASST score recommendations (score ≥7). The CASST score demonstrated a sensitivity of 31.7%, specificity of 91.7%, positive predictive value of 78.4%, and negative predictive value of 58.5%. The area under the receiver operating characteristic curve was 0.617, demonstrating poor overall discrimination. Short-term postoperative complications did not differ significantly between CASST risk groups. While CASST demonstrates high specificity, its low sensitivity and frequent misalignment with clinical practice limit its standalone utility. Further refinement and integration with intraoperative findings may improve its applicability in airway management planning.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147793069","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 retrospective study evaluated the relationship between persistent NSDs and QoL in patients who had undergone bilateral sagittal split osteotomy with/without genioplasty. Forty patients were included: 20 with persistent NSDs (>12 months postoperatively) and 20 controls. Somatosensory function was assessed using qualitative sensory tests, including two-point, light-touch, directional movement, pinprick, and sharp-blunt discrimination. Patient-reported outcomes were evaluated pre- and postoperatively using the Orthognathic Quality of Life Questionnaire (OQLQ) and Oral Health Impact Profile-14 (OHIP-14). Both groups exhibited significant improvements across all QoL domains. Although the NSD group patients demonstrated persistent sensory deficits in all qualitative sensory test parameters (all P < 0.05 compared to controls), their improvements in OQLQ and OHIP-14 were comparable to those of the control group, indicating that NSDs have a limited long-term effect on perceived QoL. Genioplasty was associated with significantly greater sensory impairment in multiple tests, while type of mandibular movement and sex showed no significant effects. Strong correlations were identified between OQLQ changes and both two-point discrimination and light-touch sensation (ρ range 0.47-0.73, all P < 0.05). These findings demonstrate significant and sustained improvements in patient overall QoL after orthognathic surgery despite persistent sensory dysfunction. In conclusion, although postoperative NSDs may develop, their long-term impact on patient QoL appears minimal. Nonetheless, the higher likelihood of somatosensory alterations associated with concomitant genioplasty should be considered during surgical planning.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147793107","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}

Reliable prognostic markers for OMM are scarce, complicating disease management and patient counselling. Tumour-infiltrating lymphocytes (TILs) have shown prognostic value in other cancers, but their potential as a biomarker in OMM is not yet well defined. Hence, a systematic literature review, following the PRISMA guidelines, was conducted. The PubMed and Embase databases were searched for studies reporting on TILs in five or more OMM patients. Two studies reporting 102 OMM patients met the inclusion criteria and were included. Despite differences in TIL assessment methods and cut-offs, approximately 25% of OMM patients had demonstrable TILs. High TIL levels were associated with improved overall survival, although this reached statistical significance in only one study, describing 20 patients. In one study, low TIL levels were significantly associated with an increased risk of distant metastasis. Overall, despite the limited number of included studies, the findings suggest that TILs may serve as a prognostic marker in OMM, with higher TIL levels indicating more favourable outcomes. Larger, standardized studies are needed to validate these preliminary observations, refine TIL assessment methodologies and cut-off values, and to explore interactions with other prognostic markers. Ultimately, integrating the evaluation of TILs into OMM prognostic models could enhance patient stratification, guide treatment planning, and improve patient counselling.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147793065","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}

Each hemimandible was mounted on a wooden base, and a metallic device similar to a Smith sagittal separator was used to stress the sagittal cut until failure. Fractures were classified as favorable (lingual split scale (LSS)1, LSS2, LSS3) or as unfavorable (LSS4). The Epker group had significantly more unfavorable fractures than the Wolford group (P = 0.027), with a 4.51-fold higher relative risk of unfavorable fractures. Hemimandible thickness did not significantly affect fracture patterns (P > 0.05). No significant differences were found between the techniques regarding tensile load, displacement, or fracture time (P > 0.05).

Zygomatic implant surgeries performed between 1998 and 2021 at Ziekenhuis Oost Limburg, Belgium were analysed. Patients with ≥2 years of follow-up were included. Data on implant survival, prosthesis survival, and surgical techniques were assessed using Kaplan-Meier survival curves and multivariable Cox proportional hazards models adjusted for age, sex, and smoking; statistical significance was set at P ≤ 0.05. Overall, 203 patients with 675 zygomatic and 223 standard implants were evaluated. The quad zygoma scheme demonstrated a significantly higher implant survival rate than the classic Brånemark scheme (P = 0.009), particularly in the anterior maxilla, although no significant difference in prosthesis survival was observed between the two. The sinus slot technique showed superior implant and prosthesis survival compared to the intrasinus approach (P = 0.002, P = 0.015). These findings suggest that the quad scheme offers advantages in implant survival, especially in the anterior maxilla, while prosthetic outcomes remain comparable between the two schemes. Additionally, the sinus slot technique may help reduce sinus-related complications. Five-year implant survival was 91.5% for the classic scheme and 94.9% for the quad scheme; 10-year survival was 83.7% and 92.6%, respectively. Personalized surgical strategies are crucial for optimizing outcomes in zygomatic implant treatments, and further long-term research is necessary to confirm these results.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147793100","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}
