Abstract:

Objective    To compare the patients' feeling and postoperative effect of using the Er∶YAG laser and conventional technique，and to investigate the applications of Er∶YAG laser in labial frenectomy. Methods    Patients were collected from the Department of Oral and Maxillofacial Surgery of Yantai Stomatological Hospital，from April 2014 to March 2015. Twenty-eight patients requiring frenectomy were randomly assigned to have treatment either with conventional surgery or with Er∶YAG laser techniques. Compare the postoperative reaction of two methods of treatment in patients，including pain，swelling，language，bleeding，chewing function and lip movement status. Results    From the pain VAS score of 3 hours，3 days，1 week and 1 month pain degree， we found the laser group was significantly lower than the traditional surgery group，and the difference was statistically significant（P＜0.05）. As for other reactions 3 hours，3 days，1 week and 1 month after the suegery，the laser group was also obviously lower than the traditional surgery group，and the difference was statistically significant（P＜0.05）. Conclusion    Patients with abnormal labial frenum using the Er： YAG laser will have a better feeling after the operation. The Er∶YAG laser surgery can shorten the operation time and reduce the postoperative pain and adverse reactions.

摘要：

目的    比较唇系带激光与传统手术治疗后患者感觉与术后效果，探讨激光在唇系带修整手术中的应用方法。方法    2014年4月至2015年3月就诊于烟台市口腔医院颌面外科的28例需要唇系带修整的患者随机分配到激光治疗组或传统的外科手术组接受唇系带修整术。比较评估2种治疗方法术后患者的反应，包括疼痛、肿胀、语言、出血、咀嚼功能和唇部运动状况等。结果    利用疼痛的VAS评分评价术后3h、3 d、1周、1个月的疼痛度，激光组明显低于传统组，差异有统计学意义（P＜0.05）。术后3 h、3 d、1周、1个月的术后其他反应的各项分数，激光组也明显低于传统组，差异有统计学意义（P＜0.05）。结论    对于唇系带异常患者，使用Er∶YAG激光进行唇系带修整术，患者术后感觉更好，可缩短手术时间，降低术后的疼痛和不良反应。
