A cohort of 60 patients was selected and divided into three groups, each consisting of 20 individuals.

Models of different fixation types of MFC flap were reconstructed from CT images. A standard internal fixation model for extracapsular condylar fracture was also included as a control. Displacement of bone graft, deformation of plates and screws, and stress distribution of plates, screws, and cortical and cancellous of the bone graft were analyzed by ﬁnite element analysis to investigate their biomechanical features. The displacement of the bone graft and deformation of plates and screws in three different fixation types showed no significant difference. The overlap type and flush type of fixation displayed the lowest and highest stress respectively. All three fixation types could satisfy the mechanical requirement and face no risk of breakage and the major displacement of the MFC bone graft. These results provide insights into the optimal fixation approach for MFC bone grafts, offering valuable guidance and reference for clinical application.","PeriodicalId":54851,"journal":{"name":"Journal of Cranio-Maxillofacial Surgery","volume":"80 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was a multi-institutional retrospective chart review of patients with RS who underwent MDO at one of three different pediatric tertiary medical centers. The primary aim of the study was to compare rates of G-tube placement following MDO among the three institutions. The primary outcome was analyzed using Fischer's exact test. The secondary aim of the study was to assess for other contributing factors to G-tube placement such as demographic differences, length of hospital stay, and age at MDO. Analysis of secondary outcomes was assessed using multiple logistic regression models. A total of 125 patients met the inclusion criteria, which required RS diagnosis, completion of MDO between 2004 and 2019, and adequate medical record availability. Sixty percent (n = 75) of subjects were categorized as isolated RS (iRS) and forty percent (n = 50) as syndromic RS (sRS). After MDO, 20% (n = 25) of all patients had G-tubes placed. Of the iRS group, 14.7% (n = 11) required a G-tube, while 28% (n = 14) of the sRS group required a G-tube. The post-operative G-tube rate was similar between institutions when considering all patients. When considering only those patients with iRS, the post-MDO G-tube rate at one center was significantly higher than the other two. Overall, most patients with RS did not require a G-tube after MDO, regardless of diagnosis. However, the significant differences in rates of G-tube placement among patients with iRS may indicate differing practice philosophies, surgical protocols, thresholds for G-tube placement, or regional influences between institutions.","PeriodicalId":54851,"journal":{"name":"Journal of Cranio-Maxillofacial Surgery","volume":"36 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
