Abstract

Objective: To observe the curative effect of botulinum toxin A on masseter hypertrophy using three-dimensional stereophotogrammetry.

Methods: 46 cases with masseter hypertrophy (92 masseters) who received botulinum toxin A injection were enrolled from May 2013 to August 2014.Data were collected before and 3,6 and 9 months after injection.

Results: The efficacy of botulinum toxin A in reducing the volume of the lower face has been proven by MAS 3D.3 and 6 months after injection, the volume reduction were measured as 7.23 ％,2.15％ respectively (P ＜ 0.05).The coefficients between middle and lower thirds of the face showed an increase compatible with thinning of the lower face with statistical significance at 3 months follow up. The increase percentage was measured by MAS 3D as 40.21％ between pre-and post-injection (P ＜ 0.05),and the increase percentage was 21.03％ at 6 months follow up (P ＜ 0.05).While 9 months after injection,the value was insignificant comparing to pretreatment at 9 months.

Conclusions: Three-dimensional stereophotogrammetry provides a safe effective and direct way to observe masseter hypertrophy.

[基于三维立体摄影测量法的定量分析A型肉毒毒素治疗咬肌肥大的疗效观察]。

目的:应用三维立体摄影测量法观察A型肉毒毒素治疗咬肌肥大的疗效。方法:选取2013年5月~ 2014年8月接受A型肉毒毒素注射的咬肌肥大患者46例(92例)。分别于注射前、注射后3、6、9个月采集数据。结果:MAS 3D证实了A型肉毒毒素对下脸体积缩小的疗效。注射后3、6个月体积缩小率分别为7.23%、2.15% (P < 0.05)。随访3个月时，面部中、下三分之一的系数增加，与下面部变薄相适应，差异有统计学意义。MAS 3D测量注射前后的升高率为40.21% (P < 0.05)，随访6个月时升高率为21.03% (P < 0.05)。而注射后9个月，与前9个月相比，价值不显著。结论:三维立体摄影测量法为观察咬肌肥大提供了一种安全、有效、直接的方法。
