目的：内窥镜辅助下经口切开复位内固定术（EAORIF）治疗下颌骨髁状突骨折最近变得流行，因为它具有微创性，无需大切口即可提供良好的可视性，并减少手术瘢痕和面神经损伤的风险。本报告描述了一项回顾性临床研究，比较了某些临床参数，包括术后功能，下颌后（RM）的方法和EAORIF.Methods：15例患者治疗的RM方法，而15个进行EAORIF 2006年7月至2011年9月在日本九州牙科学院。临床指标包括骨折线、骨折类型、接骨板使用数量、手术时间、出血量和功能项目，包括最大切迹开口、下颌偏斜、咬合不正、面部感觉异常和颞下颌关节疼痛和咔哒声。RM入路用于下颌骨髁状突骨折伴小骨段脱位。两组在所有情况下均使用了2块接骨板。两组的手术时间、最大切口间开口、下颌偏斜、咬合和术后6个月的颞下颌关节功能相似。EAORIF组的平均出血量大于RM组。RM组的一名患者面部感觉异常，持续6个月后surgery.Conclusions：它的结论是，手术治疗是适合于骨折的下颈部和髁下。两种手术在本研究的功能项目中均显示出良好的结果。
Objective: Endoscope-assisted transoral open reduction and internal fixation (EAORIF) for mandibular condyle fractures has recently become popular because it is minimally invasive, provides excellent visibility without a large incision, and reduces surgical scarring and the risk of facial nerve injury. This report describes a retrospective clinical study that compared certain clinical parameters, including postoperative function, between the retromandibular (RM) approach and EAORIF.Methods: Fifteen patients were treated by the RM approach, whereas 15 underwent EAORIF between July 2006 and September 2011 at Kyushu Dental College, Japan. Clinical indices comprised fracture line, fracture type, number of plates used, surgical duration, bleeding amount, and functional items, including maximum inter-incisal opening, mandibular deviation on the opening pathway, malocclusion, facial paresthesia, and temporomandibular joint pain and clicking.Results: The areas subjected to either approach included lower neck and subcondyle. The RM approach was used for mandibular condyle fractures with dislocation of a small bone segment. Both groups used 2 plates in all cases. Surgical duration, maximum inter-incisal opening, mandibular deviation, occlusion, and temporomandibular joint function at 6 months after surgery were comparable between groups. The average bleeding amount in the EAORIF group was greater than in the RM group. One patient from the RM group developed facial paresthesia that persisted for 6 months after surgery.Conclusions: It was concluded that surgical treatment was suitable for fractures of the lower neck and subcondylar. Both procedures showed good results in the functional items of this study.
