Objective

The present study was aimed to study the effectiveness of botulinum toxin A masseter injection and hyaluronic acid chin injection in pretext of the lower third facial contour remodeling.

Methods

60 Chinese cases that underwent a lower third of facial contour remodeling for the first time were selected. Before surgery, a conventional electromyography was performed. The Root Mean Square (RMS) values were calculated through electromyography and were recorded. Surgery was performed on all the subjects in order to compare satisfaction, muscle strength value of masseter and occurrence rate of complications post-surgery. Scores of surgery satisfaction were administered based on the attitude of medical staff, service quality and facial shape improvement through questionnaires distributed to patients.

Results

After one-year of follow-up, there were 38 cases that were very satisfied (63.34%), 20 cases were basically satisfied (33.33%) and 2 were unsatisfied (3.33%). The Root Mean Square (RMS) values were significantly declined after one month of surgery, and it began to increase after 3 months and was back to normal after 12 months. The occurrence rate of complications was high within 3 months after surgery, among which there were 5 muscle atrophy cases (8.33%), 3 facial paralysis cases (5.00%), 4 infection cases (6.67%), 3 anaphylactic reaction cases (5.00%) and 2 toxic reaction cases (3.33%). All cases were back to normal after symptomatic treatment.

Conclusion

Botulinum toxin A masseter injection and hyaluronic acid chin injection on lower third of facial contour remodeling are associated with little trauma and high plasticity.

目的

探讨A型肉毒毒素咀嚼肌注射和透明质酸下颌注射假借面部下部轮廓重塑的效果。

方法

选择60例首次面型重塑后1/3的中国人。手术前进行常规肌电图检查。肌电图计算均方根(RMS)值并记录。所有受试者均行手术治疗，比较术后满意度、咬肌肌力值及并发症发生率。通过发放给患者的问卷，根据医护人员的态度、服务质量和面型改善情况进行手术满意度评分。

结果

随访1年，非常满意38例(63.34%)，基本满意20例(33.33%)，不满意2例(3.33%)。术后1个月均方根(RMS)值明显下降，3个月后开始升高，12个月后恢复正常。术后3个月内并发症发生率高，其中肌肉萎缩5例(8.33%)，面瘫3例(5.00%)，感染4例(6.67%)，过敏反应3例(5.00%)，毒性反应2例(3.33%)。所有病例经对症治疗后均恢复正常。

结论

A型肉毒毒素咀嚼肌注射和透明质酸下颌注射治疗面部下部轮廓重塑创伤小，可塑性高。
