The primary predictor variable was dentofacial skeleton (NSCLP vs. skeletal class I).

Three-dimensional analysis revealed significant morphological differences: compared to the class I group, NSCLP patients exhibited a larger nasopharyngeal volume (<em>p</em> &lt; 0.01) and a larger minimum cross-sectional area in the nasopharynx (<em>p</em> &lt; 0.05) and palatopharynx (<em>p</em> &lt; 0.01), but a reduced height of the upper airway (<em>p</em> &lt; 0.05) and palatopharyngeal airway (<em>p</em> &lt; 0.01). Furthermore, in unilateral NSCLP patients, the transverse diameters of the nasopharynx and palatopharynx were significantly smaller on the affected side compared to the normal side (<em>p</em> &lt; 0.05). While bilateral NSCLP and class I groups demonstrated symmetry at the nasopharyngeal and palatopharyngeal levels, both exhibited significant asymmetry at the glossopharyngeal segment (<em>p</em> &lt; 0.05).</div></div><div><h3>Conclusion</h3><div>Our findings conclusively define the specific three-dimensional differences in the NSCLP upper airway, which include an enlarged yet foreshortened nasopharynx and consistent lateral asymmetries.

Inclusion criteria encompassed clinical studies, retrospective analyses, and case reports or series that described surgical techniques and reported outcomes. Studies describing TC approach modifications for orbital, infraorbital rim, or zygomatic fractures were included. Studies without specific details on modifications or outcomes were excluded. Of the initially identified articles, 22 studies met the inclusion criteria after independent screening by two reviewers.</div></div><div><h3>Results</h3><div>Twenty-two studies describing TC approach modifications were included, describing eight major categories of TC modifications. Reported variations included lateral paracanthal extensions, sutureless TC incisions, cutaneous Y-modifications, extended TC approaches, stair-step incisions, modified lateral canthotomy and aesthetic variations, lateral skin extensions and canthal-sparing techniques. These techniques were designed to improve surgical access and minimise complications such as ectropion, entropion, and scleral show. Some modifications prioritized enhanced exposure, while others focused on reducing morbidity and optimizing aesthetic results. Due to the heterogeneity of study designs and outcome measures, quantitative synthesis was not performed.</div></div><div><h3>Conclusions and Relevance</h3><div>The TC approach continues to evolve through multiple technical refinements that balance exposure and aesthetics. Awareness of these variants enables surgeons to individualise incision choices based on fracture patterns and risk profiles. The current evidence is largely descriptive and lacks standardised outcome measures, which limits direct comparisons. Prospective, well-designed studies are needed to establish the optimal modification for specific clinical contexts.</div></div>","PeriodicalId":55993,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":"127 3","pages":"Article 102670"},"PeriodicalIF":2.0,"publicationDate":"2025-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145643149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These issues are particularly pronounced in rural and remote populations, where access to specialized care and early diagnostic services is limited. Socioeconomic disparities, healthcare provider shortages, and geographic isolation contribute to delayed diagnoses and poorer outcomes in these settings. This systematic review evaluated 40 studies focused on early detection strategies for OPMDs and oral squamous cell carcinoma (OSCC) in underserved populations, particularly in rural and low-resource environments. Across 136,257 participants, the review identified diverse screening tools including oral visual examinations, toluidine blue staining, autofluorescence, chemiluminescence, mobile health (mHealth) applications, and artificial intelligence (AI)-based image analysis. The use of low-cost, portable, and technology-driven tools, especially those enabling remote diagnosis and task-sharing with frontline health workers, showed promise in increasing diagnostic accuracy and screening reach. However, variability in performance, training needs, and follow-up adherence remain key limitations. The review also highlighted widespread use of community-based strategies and the value of interdisciplinary collaboration, particularly where dental specialists are not readily available. Innovative, context-sensitive screening tools supported by interdisciplinary networks hold strong potential to enhance early detection of OPMDs and OSCC in rural and underserved communities. Mobile technologies and AI applications are emerging as practical adjuncts to traditional screening methods. To optimize impact, future efforts should prioritize validation of these tools against histopathological standards and the integration of trained non-specialist health workers in community-based screening programs.</div></div>","PeriodicalId":55993,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":"127 3","pages":"Article 102667"},"PeriodicalIF":2.0,"publicationDate":"2025-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145598548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
