目的 :评价肋骨移植治疗生长期患者单侧颞下颌关节强直合并颌骨畸形的效果。方法 :对2010年1月—2014年12月采用肋骨移植同期治疗单侧颞下颌关节强直合并颌骨畸形的生长期患者进行CT影像学分析,采用Pro Plan CMF 1.4软件对术前、术后1周和随访1年以上的下颌支高度、肋骨长度和颏点偏斜程度进行测量和比较。采用SPSS 17.0软件包对数据进行配对t检验。结果 :6例患者纳入研究,年龄3~7岁,平均5岁。肋骨术后平均延长下颌支高度6.2 mm,颏点偏斜平均矫正5.3 mm;术后平均随访2.7 a,肋骨平均生长6.9 mm,健侧下颌支平均生长4.4 mm,患侧4.3 mm(P>0.05)。结论:肋骨移植可以同期治疗颞下颌关节强直及合并的颌骨畸形,具有生长潜能,但是长期效果有待于进一步观察。
OBJECTIVE: To evaluate the effect of rib transplantation on patients with unilateral temporomandibular joint ankylosis complicated with jaw deformity. Methods: The CT images of the growing patients with unilateral temporomandibular joint ankylosis and jaw deformity treated by rib transplantation from January 2010 to December 2014 were analyzed. Pro Plan CMF 1.4 software was used to evaluate the preoperative and postoperative 1 The length of the mandibular branch, the length of the rib and the deviation of the chin point were measured and compared over a one-week and one-year follow-up period. Data was paired t-test using SPSS 17.0 software package. Results: Six patients were enrolled in the study, aged 3 to 7 years, with an average of 5 years. The average length of the mandibular branch was 6.2 mm and the deviation of the chin point was corrected to 5.3 mm. The mean follow-up of 2.7 a was 6.9 mm. The average length of the rib was 6.9 mm. The average length of the mandibular branch was 4.4 mm. The affected side was 4.3 mm (P> 0.05) ). CONCLUSION: Rib-grafting can treat the temporomandibular joint ankylosis and combined jaw deformity with growth potential, but the long-term effect needs to be further observed.
