Several techniques have been combined with orthognathic surgery to enhance the volume and definition of this region, such as zygomatic osteotomy. Two female patients, aged 22 (Case A) and 29 (Case B), with class II (Case A) and III (Case B) malocclusion, respectively, complained about facial aesthetics due to a long face and lack of malar projection. Le Fort I osteotomy to advance the maxilla, bilateral mandibular ramus osteotomy to set back the mandible, mentoplasty for advancement and width reduction, and zygomatic osteotomy were erformed. The patients underwent computed tomography scans, and superimposed images indicated that a volumetric increase in the malar region was achieved through the anterolateral movement of the zygomatic body. Improvements were noted in the paranasal region (Case A), better alignment of the upper and lower lips, the chin region, and an improved chin-neckline ratio (in both cases). The patients were satisfied with the results and are under follow-up. In summary, zygomatic osteotomy combined with orthognathic surgery proved to be a predictable and safe strategy for increasing malar prominence, with satisfactory aesthetic and functional outcomes.","PeriodicalId":51711,"journal":{"name":"Journal of the Korean Association of Oral and Maxillofacial Surgeons","volume":"51 2","pages":"108-116"},"PeriodicalIF":0.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12041431/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144045825","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}

Changes in bone volume at 12 months were evaluated by three-dimensional (3D) analyses of cone-beam computed tomography images. Factors including age, sex, smoking status, span, number of ACSs, and perforation were assessed for associations with changes in sinus bone volume using uni- and multivariable analyses based on the generalized estimating equation.Results: : Medical records of 108 patients were collected and retrospectively evaluated, with 135 regions of interest defined (CA, 45; LA, 90). The changes in bone volume at the sinus floor were 159.38±134.52 mm3 and 486.83±253.14 mm3 in the CA and LA groups, respectively. Bone volume changes in the CA group were significantly affected by the number of ACSs (P<0.001) and perforation of the sinus membrane (P<0.001), whereas bone volume changes in the LA group were significantly affected by the number of ACSs (P=0.001).Conclusion: : Use of ACS for maxillary sinus elevation resulted in detection of new bone formation in 3D analysis.

This study evaluates the efficacy of ultrasonography as a diagnostic and follow-up tool for the management of chronic recurrent sialadenitis. Three patients underwent sialendoscopy, which involved ductal dilation, removal of mucous plugs, and steroid administration. Ultrasonography was used postoperatively to monitor changes in ductal structure, including megaduct size, and to assess clinical outcomes. All three cases showed marked improvement in clinical symptoms after treatment. Ultrasonography demonstrated a reduction in megaduct size and provided real-time visualization of ductal and glandular changes. Compared to traditional imaging methods such as magnetic resonance imaging or sialography, ultrasonography offered a practical and safe option for follow-up assessment. This study highlights the utility of ultrasonography as an accessible, non-invasive, and effective tool for evaluating treatment outcomes in chronic recurrent sialadenitis. By offering detailed visualization of ductal changes and facilitating longitudinal follow-up, ultrasonography can optimize the management of this condition.","PeriodicalId":51711,"journal":{"name":"Journal of the Korean Association of Oral and Maxillofacial Surgeons","volume":"51 2","pages":"117-122"},"PeriodicalIF":0.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12041434/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144039183","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}

The aim of the study was to document the experience with GMT cases in a single private dental college and hospital in an effort to uncover the etiology, prevalence, fracture sites, and various types of treatment in GMT.Materials and methods: : This was a retrospective study conducted at Saveetha Dental College and Hospital in Chennai. Data from patients diagnosed with maxillofacial trauma between January 2019 and December 2023 were retrieved from hospital records, and those aged ≥60 years were included in the study. Patients' basic demographic details and the prevalence, etiology, fracture sites, and various treatments of GMT were recorded and analyzed. The collected data were entered into a structured database and analyzed using IBM SPSS Statistics ver. 23.0 (IBM).Results: : A total of 867 cases were screened, and 37 (4.04%) GMT patients were finally included in the study. The mean age of the study population was 65±5 years, and there were six females and 31 males. A ground-level fall was the common etiology (n=17), and the most common site of fracture was the mandible (n=15). Open reduction and internal fixation (ORIF) was the most common treatment modality (n=24) among included cases.Conclusion: : Although the prevalence of GMT was low, ground-level falls were a common reason for trauma; hence, geriatric patients require comprehensive care in home and outdoor settings. Enhanced anesthetic and surgical techniques have made ORIF a suitable treatment approach in the present era.","PeriodicalId":51711,"journal":{"name":"Journal of the Korean Association of Oral and Maxillofacial Surgeons","volume":"51 2","pages":"102-107"},"PeriodicalIF":0.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12041430/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144057657","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}

Inclusion criteria included adults older than 18 years with condylar fractures not indicated for open reduction and internal fixation. The guide was fabricated using computed tomography or cone-beam computed tomography scans and 3D printing to control the degree and depth of the needle through the guide to aspirate hemarthrosis.Results: : Six joints from five patients (average age 52.4 years) were treated using the guide. Post-procedural magnetic resonance imaging confirmed complete resolution of hemarthrosis in all cases. A representative case demonstrated successful outcomes with normal healing and no complications at 8 months post-procedure.Conclusion: : The customized TMJ injection guide, using ear-based reference points, significantly enhances the accuracy and safety of TMJ arthrocentesis.
