{"title":"Open Versus Closed Management for Gunshot Wounds of the Mandible – Which More Frequently Achieves Satisfactory Bony Union? A Systematic Review and Meta-Analysis","authors":"Thomas Pepper MBBS, BDS, MSc ,&nbsp;David Powers MD, DMD","doi":"10.1016/j.joms.2025.04.003","DOIUrl":"10.1016/j.joms.2025.04.003","url":null,"abstract":"<div><h3>Purpose</h3><div>Closed management of high-energy mandibular injuries has been considered the gold standard for many years, but open management is preferable for its shorter overall treatment time. At present, there is a paucity of evidence on which to base management decisions, and as such there is a priority to review the literature to define the optimal treatment for mandibular gunshot wounds (GSWs).</div></div><div><h3>Method</h3><div>The study design was a systematic review with meta-analyses and the protocol was designed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. Electronic searches of published literature in the MEDLINE and Embase databases (1980-present) were conducted. Search terms included “gunshot”, “firearm”, “mandible”, and “jaw”. Inclusion criteria were randomized controlled trials (RCTs), cohort studies, case-control studies, and case series written in English describing studies involving patients with mandibular fractures caused by GSWs [population] containing information on treatment by either open reduction and (nonwire) internal fixation [intervention] or by closed reduction ± external fixation [comparator], and the frequency of bony union and complications [outcomes]. Meta-analysis was conducted using the Mantel-Haenszel odds ratio (OR) as the measure of effect. The quality of evidence was assessed using the Cochrane Risk of Bias 2 tool for RCTs and the Newcastle-Ottawa Scale for observational studies.</div></div><div><h3>Results</h3><div>159 studies were identified overall of which 6 studies (3.7%; 3 observational studies and 3 RCTs) met the eligibility criteria. Due to high heterogeneity the study subtypes were analyzed separately. In the observational studies (n = 137), open management resulted in bony union 43/52 (82.7%) times, whereas closed management resulted in bony union 78/85 (91.8%) times (OR 0.40, 95% CI 0.14 to 1.15, <em>P</em> = .09). In the RCTs (n = 190), open management resulted in bony union 89/95 (93.7%) times, whereas closed management resulted in bony union 70/95 (73.7%) times (OR 6.86, 95% CI 2.42 to 19.46, <em>P</em> = .0003).</div></div><div><h3>Conclusion</h3><div>The practicalities of treating mandibular GSWs are nuanced, and the recommendation of a one-size-fits-all management approach would be inappropriate. However, there is sufficient evidence in the findings of this systematic review to support open management as first-line treatment, with closed management considered if the former is clinically or logistically unfeasible.</div></div>","PeriodicalId":16612,"journal":{"name":"Journal of Oral and Maxillofacial Surgery","volume":"83 7","pages":"Pages 852-862"},"PeriodicalIF":2.3,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144017542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
