目的探讨长螺钉在下颌骨髁突矢状骨折治疗中的应用。方法采用耳屏前切口入路,用长14~16mm、直径2mm的钛钉。对15例(19侧)髁突矢状骨折(主要为囊内骨折A型)患者行解剖复位后长螺钉固定,术后复查颌面部三维CT,对治疗效果进行评价。结果 95%以上的患者都能恢复到受伤前咬合关系,张口度达3.5cm以上,面部外形对称,颞颌关节无弹响,无疼痛不适症状,无面神经损伤及颞颌关节强直等后遗症。结论长螺钉固定髁突囊内矢状骨折效果肯定。
Objective To investigate the application of long screw in the treatment of mandibular condyle sagittal fracture. Methods The method of trabeculectomy approach, with a length of 14 ~ 16mm, diameter 2mm titanium nail. Fifteen patients (19 sides) with condylar sagittal fracture (mainly type A intracapsular fracture) were treated with long screw fixation after anatomic reduction. The three-dimensional maxillofacial CT was performed after operation to evaluate the therapeutic effect. Results More than 95% of the patients recovered to the occlusal relationship before injury. The mouth opening degree was more than 3.5cm. The shape of the face was symmetrical. The temporomandibular joint had no ringing, no pain and discomfort, no facial nerve injury and sequelae of temporomandibular joint. Conclusion Long screw fixation of the sagittal sac in the sagittal fracture is effective.
