【摘要】：目的总结天然珊瑚充填治疗小颏畸形的远期疗效,探讨天然珊瑚与新生骨间的体积关系及新生骨的稳定性。方法回顾分析1998年10月-2004年9月,采用颏部水平截骨结合天然珊瑚块充填治疗的12例小颏畸形患者临床资料。男7例,女5例;年龄15~28岁,平均18.5岁。术前、术后即刻及末次随访时对患者面容及头颅X线片进行测量,分析下唇点至颏下点垂直距离、颏前点至鼻根点和下牙槽点连线的距离、下牙槽点至颏下点的垂直距离、颏部截骨间隙垂直距离,并计算各指标复发率。结果患者口内切口均Ⅰ期愈合,无手术并发症发生。患者均获随访,随访时间8~12年,平均9.2年。头颅X线片复查示,8年后珊瑚块蜂窝状结构均完全消失,被骨组织替代。8年后取出钛板时见颏部新生骨具有良好的强度和颏肌骨膜附着。末次随访时下唇点至颏下点垂直距离、下牙槽点至颏下点的垂直距离、颏部截骨间隙垂直距离均较术后即刻缩短,平均复发率分别为6.1%、22.9%、31.7%;而颏前点至鼻根点和下牙槽点连线的距离无明显变化。9例患者对手术疗效满意;3例再次调整颏部形态边缘。结论天然珊瑚充填治疗小颏畸形后,尽管存在部分体积丢失,但能获得稳定的新骨和满意的远期疗效。
[Abstract]:Objective to summarize the long-term effect of natural coral filling in the treatment of mental malformation and to explore the volume relationship between natural coral and new bone and the stability of new bone. Methods from October 1998 to September 2004, the clinical data of 12 patients with mental malformation were retrospectively analyzed. There were 7 males and 5 females, aged 15 to 28 years (mean 18.5 years). Before operation, immediately after operation and at the last follow-up, the facial features and head X-ray films were measured to analyze the vertical distance between the lower lip point and the submental point, the distance between the mental anterior point and the nasal root point and the inferior alveolar point, and the vertical distance between the inferior alveolar point and the submental point. The vertical distance of mental osteotomy space was calculated and the recurrence rate of each index was calculated. Results all the incisions were healed in the first stage, and no complications occurred. All patients were followed up for 8 ~ 12 years (mean 9.2 years). After 8 years, the honeycomb structure of corals disappeared completely and was replaced by bone tissue. After 8 years removal of titanium plate, it was found that the new mental bone had a good strength and the geniofilm periosteum attached. At the last follow-up, the vertical distance between the lower lip point and the submental point, the vertical distance between the inferior alveolar point and the submental point, and the vertical distance between the mental osteotomy space and the inferior alveolar point were shorter than those immediately after operation. The average recurrence rate was 6.1and 22.9g, respectively, while the distance from the anterior mental point to the nasal root point and the inferior alveolar point did not change significantly in 9 patients. Conclusion Natural coral filling can obtain stable new bone and satisfactory long-term effect despite partial volume loss in the treatment of mental malformation.
