摘　　要：【目的】探讨微型夹板联合环颌结扎固定治疗儿童下颌骨骨折的疗效。【方法】选取2011年2月至2014年12月本院口腔中心诊治的下颌骨骨折患儿69例，均由本院同一位口腔科医师采用微型夹板联合环颌结扎固定治疗，观察围手术期指标和术后疗效。【结果】69例患儿的手术时间36．8-47．3（41．0±6．8）min，术后均未出现明显的再出血现象；术后咬合关系恢复理想59例，3例患儿出现前牙区小开牙合，采用颅颌弹性绷带进行配合治疗，2例伴有髁突骨折患儿，留置小环术后配合颌问结扎治疗。术后随访的过程中，患儿均未出现牙龈溃烂、出血，术后平均骨折愈合时间（3．14-0．3）个月。术后即刻，张口度正常的有47例、一度受限20例、二度受限2例，术后3个月复查所有患儿的张口度均恢复正常，术后3个月的张口度显著优于术后即刻（P〈0．05）；术后即刻与术后3个月患儿的牙龈指数（GI）、菌斑指数（PLI）、龈沟出血指数（SBI）比较差异均无统计学意义（P〉0．05）。【结论】微型夹板联合环颌结扎固定治疗儿童下颌骨骨折手术效果可靠，对患儿张口度恢复及牙周口腔健康状况无不良影响。[ Objective] To surmnarize the effects of the miniplate combined with ring jaw ligation fixation in chil- dren of mandibular fracture. [ Methods ] Clinical data of sixty-nine cases of children with mandibular fracture in our hospital from February 2011 to December 2014 were selected and analyzed retrospectively. They were treated with the miniplate combined with ring jaw ligation fixation by the same dentist. The perioperative indexes and postoperative curative effect were observed and analyzed. [ Results] The operative time of 69 cases was 36.8 ±47.3 min （average 41.0 ± 6.8） min. The phenomenon of repeated bleeding did not ocure. The occlusal relationship was improved significantly in 59 cases. A small opening in the anterior region （occlusion） occurred in 3 cases. They were treated with the craniomaxillary elastic bandage. Two cases with condylar fracture were treated with indwelling ring operation combined with intermaxillary ligation. No gingival ulceration and bleeding occurred during the postoperative follow-up stage. The average healing time was （3.1 ±0.3） months. After operation, 47 cases was normal over the mouth opening degree , and 20 cases were limited with first degree and 2 cases with second degree. 3 months after the operation, the mouth opening degrees in all of the cases were returned to normal. The mouth opening degrees in 3 months after operation were signifi- cantly improved compared with the time immediately after surgery. However, no statistical difference between the time immediately after surgery and 3 months postoperation was observed in GI, PLI and SBI（ P 〉0.05）. [ Conclusion] The miniplate combined with ring jaw ligation is reliable effect in the treatment children mandibular fracture. The therapy has no adverse effect in the recovery of mouth opening degree and the periodontal oral health.
