To investigate the technique and clinical effect in the surgical reduction and screw fixation of sagittal condylar fractures.
Open treatment was performed on 21 cases (23 condyles) with sagittal condylar fractures. The condylar fracture segment was reduced and fixed by screw (long screw or lag screw). The patients began the mandible movement exercise early after the operation, and follow-up was performed in the first half year after the operation.
Favorable results were obtained in all cases. Slight malocclusion was observed in 3 cases accompanied with mandible fracture, but normal occlusion was almost reestablished after one week of intermaxillary traction. The CT examination indicated the ideal condition of reduction and fixation of these condylar fractures. During the follow-up, the mouth opening was normal, and mandible movement and function was satisfactory.
The technique of reduction and screw fixation in condyle sagittal fracture can obtain stable reduction and fixation.
探讨髁突矢状骨折手术复位及螺钉固定的技术和临床效果。
对21例（23侧髁突）髁突矢状骨折患者行切开治疗。采用螺钉（长螺钉或拉力螺钉）对髁突骨折块进行复位和固定。患者术后早期开始下颌运动锻炼，并在术后半年进行随访。
所有病例均取得良好效果。3例合并下颌骨骨折患者出现轻度咬合紊乱，但经颌间牵引1周后咬合基本恢复正常。CT检查显示髁突骨折复位及固定情况理想。随访期间，张口正常，下颌运动及功能良好。
髁突矢状骨折的复位及螺钉固定技术可获得稳定的复位和固定。
