The development and progression of OSCC are closely linked to various aetiological factors. Early signs of OSCC may manifest as oral lesions, genetic abnormalities, and chronic inflammation. Lesions with dysplastic features have a high risk of malignant transformation into OSCC. Moreover, dysplastic lesions are characteristic of many oral potentially malignant disorders (OPMDs). Currently, there is no unified standard of treatment for OPMD patients, due to the variability in risk factors and mechanisms of transformation. Therefore, it is essential to detect and manage OPMDs at an early stage in order to prevent their malignant transformation into OSCC. This necessitates analysing OPMD mechanisms to identify objective markers for predicting the risk of malignant transformation. The aim of this review was to describe the process of OPMD transformation into OSCC under the influence of environmental, immune, microbiome, and molecular factors.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901383","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}

Compared to the preoperative state, the largest long-term changes of the TMJ were observed in the condyles: mean volume decrease of 9.94% for the right condyle and 8.35% for the left. Condylar volume changes contributed most to the changes in condylar height (effect size right/left, η2 = 0.71/0.72) and horizontal postoperative skeletal relapse (η2 = 0.22/0.20). In contrast, glenoid fossa and joint space changes were modest and unassociated with skeletal relapse. Five female patients (10%) showed signs of PCR, with a mean reduction in condylar volume of 32%, a significant loss of condylar height and skeletal relapse. In conclusion, at 5 years following MMA, mainly condylar volume changes were observed, which had the largest effect on long-term postoperative skeletal relapse when compared to glenoid fossa and joint space changes.

To flatten the labiomental fold, a solid graft can be inserted into the concavity between alveolar process and chin prominence. An original technique is proposed that uses a composite graft made of a bone block fixed directly to the mandibular basal bone and covered with a layer of cartilage, to overcome the flaws associated with previously described techniques. This technique was used over a 7-year period to treat 38 patients, either to prevent or to correct an excessively deep labiomental fold after advancement genioplasty, or simply to fill an existing deep fold even though a genioplasty was not performed. Only two cases of failure occurred: one due to suture dehiscence, the other due to infection of the graft. The graft also provides support to the lower lip and corrects the sagittal discrepancy between the basal bone (i.e. chin) and alveolar bone (i.e. teeth and lower lip) that often coexists in these patients. The procedure takes only a few minutes and presents a minimal risk of complications; therefore, it can be considered a simple and effective technique.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142822993","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}

A surgical protocol was defined as the unique combination of a sequence of standard surgeries, their timing, and the surgical techniques employed. Overall, 33 unique surgical protocols for CP, 54 for UCLP, and 51 for BCLP were identified. Notable findings included the trend towards early hard palate closure, uniform timing of lip closure, and the popularity of primary cleft rhinoplasty. Nevertheless, practice variations were most pronounced in the timing of alveolar closure, the number of standard surgeries, and the application of additional standard procedures. This study highlights the diversity of treatment protocols across Europe, despite considerable convergence of treatment practices over time.

Both a case-control design and a cohort design were used in this study to evaluate the association between CMF trauma and TMJD, and to investigate how CMF trauma impacts the number of days on work disability among pwTMJD. The main study finding was that many types of previous CMF trauma were strongly associated with TMJD, with mandibular fractures having the strongest association (adjusted odds ratio 11.4). Furthermore, the strongest association for an increased number of annual days on work disability was found for pwTMJD with a history of CMF trauma.
