目的通过对髁状突骨折治疗后引起的临床症状的观察,探讨可能引起这类临床症状的相关解剖因素,并追踪引起此类临床症状的骨折类型与治疗方法,以期得到该类骨折的最佳治疗方法。方法髁状突骨折治疗改建后颞下颌关节(TMJ)用MSCT扫描,在工作站上进行MPR和TMJ形态的测量,比较其相关性,分析治疗方法选择的正确与否。结果病例开口受限组骨折侧髁状突在关节窝的位置,髁状突内外径、关节窝前后斜面宽度及倾角等参数上有显著差异,且变异系数较大。结论对髁状突骨折的患者,应手术达到解剖复位,坚强内固定,同时应将移位的关节盘复位,否则会发生关节强直或张口受限等并发症。
Objective To observe the clinical symptoms caused by the treatment of condylar fractures and to explore the relevant anatomical factors that may cause such clinical symptoms and to follow the types of fractures and treatment methods that cause these clinical symptoms in order to obtain the best of these fractures treatment method. Methods Condylar fractures were treated with MSCT scan of temporomandibular joint (TMJ) after reconstruction. The MPR and TMJ were measured on the workstation. The correlation was analyzed and the correctness of the treatment was analyzed. Results There were significant differences in the parameters of the mandibular condyle in the limited open group, including the position of the joint socket, the internal and external diameters of the condyles, the width and inclination of the incline before and after the joint socket, and the coefficient of variation was large. Conclusions Patients with condyle fractures should be anatomically removed and strongly internalized during surgery. At the same time, the displaced disc should be repositioned or complications such as ankylosis or mouth opening may occur.
