It is a known mandibular reconstruction option in children, and though poorly understood and unpredictable, the concerns of developmental changes to donor and recipient tissues shared by other treatment options are nonexistent. The definitive role of periosteum during bone regeneration remains largely unknown. Objective The objective is to review the literature on the clinical and molecular mechanism evidence of this event. Methods Our search methodology was modeled after the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines. Search strategies were categorized into search 1 for clinical evidence of mandibular regeneration and search 2 for gene expression review for craniofacial regeneration. The quality assessment of each publication was undertaken, and inclusion criteria comprise mandibular continuity defect for search 1 and use of gene expression assay propriety kit for search 2. Results 33 studies were selected for search 1 while four studies with non-human subjects were selected for search 2. Monitoring of PMBR onset was advised at 2 weeks post-operative, and the gene expression results showed an upregulation of genes responsible for angiogenesis, cytokine activities, and immune–inflammatory response in week 1 and skeletal development and signaling pathways in week 2. Conclusions The results suggest that young periosteum has a higher probability of PMBR than adult periosteum, and skeletal morphogenesis regulated by skeletal developmental genes and pathways may characterize the gene expression patterns of PMBR.","PeriodicalId":46447,"journal":{"name":"Craniomaxillofacial Trauma & Reconstruction","volume":" 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135192014","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}

Objective: The surgical treatment of mandibular fractures has undergone several changes over the past 100 years, since the use of wires and intermaxillary fixation, until today where most of the fractures are treated with internal fixation using plates and screws. For the correct use of this hardware, the surgeon must have adequate knowledge of jaw anatomy to prevent complications during the insertion of screws like in fractures of the mandibular body and angle, when the screws of the plate installed in the compression zone can damage the inferior alveolar nerve within the mandibular canal. Methods: To minimize this complication, 66 hemimandibles of adult patients were analyzed in CT scans and manipulated with Dental Slice® software, (BioParts®, Brazil) and measured the shortest distance from the inferior cortex of the mandibular canal to the inferior cortex of the mandibular body during the path of the inferior alveolar nerve, since the mandibular foramen until the mental foramen. Results: The result obtained showed a wide variation of the shortest distance measured (3.52 mm–11.5 mm) with an average of 7.99 mm. Conclusion: The conclusion demonstrated a minimum distance of 3.52 mm below the cortical mandibular canal to the lower border of the mandible and should be considered as a safety margin during the application of fixing the material in the region of the mandibular body.","PeriodicalId":46447,"journal":{"name":"Craniomaxillofacial Trauma & Reconstruction","volume":"3 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135873758","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}

Objective The aim of this work is to offer a representative sample of facial laceration and identify the recreational activities associated with the highest risk of such injuries. Methods We conducted aretrospectivestudy of patients reported to the National Electronic Injury Surveillance System (NEISS) which collects information on injuries related to consumer products. Patients were included in our dataset from the time period of 2012 to 2021 if they sustained a facial laceration that was caused by a recreational activity. Results Our findings reveal 2,383,761 facial lacerations between the study period examined. Young male white adults were more likely to sustain a facial laceration related to recreational activities. Injuries related to exercise equipment were also more likely seen in male patients. The most common cause of facial lacerations was associated with bicycles and basketball. Conclusions This study found that young white adults are notably prone to facial lacerations, with recreational activities such as bicycling and basketball accounting for the majority of cases. Understanding these statistics is pivotal for implementing targeted strategies to prevent these injuries and their associated consequences.","PeriodicalId":46447,"journal":{"name":"Craniomaxillofacial Trauma & Reconstruction","volume":"18 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135973714","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}

Objective This study described the long-term outcomes of patients who received either conservative or surgical treatment for zygomaticomaxillary complex (ZMC) fractures. It accounted for the perspectives of both patients and surgeons, and explored factors associated with patient satisfaction. Methods Patients with unilateral ZMC fractures 2007–2018 were invited to follow-up clinical examinations and photographic documentation. Patient experiences were recorded using a questionnaire. A review panel assessed computed tomography (CT) scans and photographs. Patient and surgeon perspectives of detecting functional sequelae were assessed, and a correlation matrix was used to evaluate different perspectives of perceiving malar asymmetry. Results The study sample consisted of 180 patients, of which conservative treatment was given to 43 patients and surgical treatment to 137 patients. Median follow-up time was 72.5 months after trauma. Overall satisfaction was 92.8%, with no significant difference between treatment groups. Patients and surgeons showed marked differences in detecting functional sequelae. Predicted malar asymmetry on CT scans did not correlate to findings on photographs or reports by patients. Conclusions A predicted sunken cheek on CT imaging does not necessarily lead to long-term visible asymmetry of the malar region. Surgeons should acknowledge different perspectives when predicting and assessing long-term sequelae of ZMC fractures, and seek consensus on when to perform surgical reconstructions.","PeriodicalId":46447,"journal":{"name":"Craniomaxillofacial Trauma & Reconstruction","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136312068","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}

Objective To describe the advantages, challenges, and potential indications of the submental artery island flap as a local pedicled flap for head and neck reconstruction. Methods We conducted a comprehensive review of the literature to describe the submental artery island flap's surgical technique, indications, and outcomes. Data sources included peer-reviewed articles, case reports, and clinical studies on using the submental flap in head and neck surgery reconstruction. Results The submental artery island flap, while offering advantages such as minimal donor site morbidity, and good cosmetic outcomes, presents challenges related to the pedicle dissection and patient selection. This flap is particularly suitable for defects in the oral cavity, oropharynx, parotid bed, and midface or neck skin. Simultaneous neck dissection is feasible but should be approached with caution in patients with a history of prior neck surgery. Conclusions The submental artery island flap is a valuable option for selected cases. When performed in the right patient with a correct technique, this flap can reconstruct defects in the oral cavity, oropharynx, parotid bed, and skin of the midface or neck with a minimally visible scar of the donor site.","PeriodicalId":46447,"journal":{"name":"Craniomaxillofacial Trauma & Reconstruction","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135858178","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}
