下颌骨粉碎性骨折临床治疗的研究.docx

碎性骨折的主要表现。直接复位和固定、截骨复位以及植骨均是不同类型骨折的有效治疗方法。下颌骨粉碎性骨折的常用治疗方法是ORIF，固定材料有重建钛板、微型钛板、钛网等，IMF逐渐成为手术治疗的辅助手段。结论下颌骨粉碎性骨折治疗复杂。IMF作为传统治疗方法，仅适用于骨折无明显移位的患者，ORIF是目前提倡的广泛应用的治疗方法。下颌骨粉碎性骨折固定要求完全负载固定，以重建钛板作坚固固定是目前最常用治疗方法。以往术者多采用Mini-plate+IMF，克服了IMF时间过长的缺点，操作简便，固定可靠，易被一般的术者掌握。两种方法均存在其优点及不足，手术方式也取决于术者的操作经验等因素。相同的患者是否可以采取不同的治疗方法，有待于病例随机对照试验来证实。关键词下颌骨粉碎性骨折重建钛板小型钛板坚固内固定颌间固定6ACLINICALSTUDYONTREATMENTOFCOMMINUTED MANDIBULAR FRACTURESABSTRACTHistorically,the accepted theory was that we should not open theseinjuries because wewould strip the blood supply to the osseousfragments,and most comminuted mandibular fractures were treated by closedreduction .More recently, open reduction and stable internal fixation hasbeen advocated for comminuted fractures. Arguments continue as to whetheran open approach is indicated for comminuted mandibular fractures .many casesstill develop complications post operations . Domestic documents are justsimply case reportsObjectiveTo evaluate the epidemiology and the treatment of comminutedmandibularfractures ,and we sought to assess the methods of treatment used and outcomes .MethodA retrospective study of 60 mandibular comminutedfractures was presentedwith respect to age，sex，cause of fractures，time between injuryandoperations, associated systemic injuries，pattern of fractures，treatmentsand complications. In the clinical study The records of all patients who wereidentified as having comminuted fractures of the mandible over 1-year periodwith sufficient follow-up were collected and analyzed for demographic7information, treatment rendered, and outcomes. Standard descriptivestatistics were used to analyze the data.ResultTraffic accident is the main cause of comminuted mandibularfractures，which occurs mainly in young adult males.early diagnosis and management ishighlighted. Fratures in symphysiswas morecommon thanin othersites.The fractures are oftenaccompaniedwith systemicinjuries .Reduction of mouth opening, malocclusion and facial deformities were thethree main signs
