两种颌后入路治疗下颌骨髁突骨折方法的研究

目的:探讨两种颌后入路治疗下颌骨髁突颈骨折的治疗方法及效果。方法:64例成人下颌骨中低位髁突颈骨折患者,随机分为A、B两组,经颌后入路,分别采用腮腺前缘入路及横断腮腺入路,解剖复位髁突骨折行坚强内固定术。结果:64例患者均取得良好解剖复位,咬合关系恢复良好,无关节强直出现。A组2例出现面神经麻痹。B组2例出现涎瘘,4例出现面神经麻痹症状。结论:颌后入路可有效治疗髁突骨折,且腮腺前缘入路较横断腮腺入路减少了手术并发症的发生。

Comparative Study of Two Retromandibular Approaches for Reduction of Condylar Neck Fracture

Objective: To compare two retromandibular approaches for reduction of mandibular condyle neck fracture. Methods: 64 adult patients were included in this study and were randomly divided into group A and group B. Group A included 32 patients who were treated with retromandibular transparotid approach. Group B included 32 patients who were treated with retromandibular antero-parotid approach. Results: All 64 cases achieved satisfactory anatomic reduction and occlusal relationship. No ankylosis of temporomandibular joint was found in all patients. In group A, two patients had facial nerve injury after surgery, while in group B four parients got facial nerve injury and two got salivary fistula. Conclusion: Retromandibular approach was effective in condyle neck fracture reduction. Compared with transparotid approach, antero-parotid approach reduced the surgical complications.
