However, atypical fracture configurations that do not conform to established subtypes are occasionally encountered in clinical practice. This technical note describes an unusual V-shaped outward displacement fracture of the zygomatic arch and proposes its recognition as a novel subtype within the recently described modified classification system for zygomatic arch fractures. A patient presenting following a motor vehicle accident exhibited an isolated zygomatic arch fracture with outward (lateral) displacement of arch fragments, forming a distinctive V-shaped configuration. Unlike conventional zygomatic arch fractures, which characteristically produce trismus through coronoid process impingement, this variant preserved mouth opening and manifested primarily as an aesthetic deformity. Management considerations for this pattern differ from standard approaches applied to conventional subtypes. The described fracture pattern is clinically and biomechanically distinct from the seven subtypes currently enumerated in the modified classification. Incorporation of this variant as a new subtype would enhance the comprehensiveness and clinical utility of the classification, enabling more accurate diagnosis and tailored surgical planning for atypical isolated zygomatic arch fractures.</p>","PeriodicalId":51711,"journal":{"name":"Journal of the Korean Association of Oral and Maxillofacial Surgeons","volume":"52 3","pages":"160-163"},"PeriodicalIF":1.6,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13329066/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148354738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While anatomical, behavioral, and access-related factors are known to influence extraction outcomes, the role of racial and ethnic characteristics in shaping extraction techniques, preferences, and disparities has not been synthesized. This scoping review aimed to explore and map the existing evidence on how racial, ethnic factors influence dental tooth extraction. A search was conducted across PubMed, Scopus, Google Scholar using a combination of MeSH terms and keywords related to dental extraction, race, ethnicity, anatomy, and sociocultural behavior. The review followed PRISMA-ScR guidelines. A total of 15 studies were included, encompassing anthropological, clinical, forensic, public health perspectives. The review identified key racial anatomical traits (e.g., root morphology, dental arch form, bone density) that affect extraction difficulty, particularly among Caucasoid, Mongoloid, and Negroid populations. Ethnic and cultural factors-health beliefs, care-seeking behavior, and access disparities-played a role in extraction timing and technique. Provider bias, lack of diversity within the dental workforce emerged as contributing factors to inequitable care delivery. Integrating this understanding into dental education, clinical guidelines can support equitable, culturally competent care. Further research is warranted to bridge anatomical evidence with behavioral and structural determinants of extraction disparities.</p>","PeriodicalId":51711,"journal":{"name":"Journal of the Korean Association of Oral and Maxillofacial Surgeons","volume":"52 3","pages":"139-149"},"PeriodicalIF":1.6,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13329073/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148354736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a case involving a 31-year-old Chinese female presenting with skeletal relapse twelve years after the primary bimaxillary surgery. Preoperative imaging identified a 1.5×1.5 cm circular osseous defect in the right mandibular body, communicating with the IAN canal. To bypass the defect site, a unilateral HOSSO was performed on the right mandible, while a standard sagittal split ramus osteotomy was utilized on the left. Postoperative clinical and radiographic evaluations at six months demonstrated satisfactory facial profile improvement and stable occlusion, with absence of neurosensory deficits or unfavorable fractures.
