Classification of Chinese glabellar wrinkles and methods of botulinum toxin type A injection

目的对美容就医者的眉问纹形态及相对应的肌肉收缩模式进行分类，用于指导A型肉毒毒素的注射治疗。方法随机采集60例20～65岁美容就医者的眉间纹，对其进行分类，并分析各类型的肌肉收缩模式，使用A型肉毒毒素对参与收缩的肌肉进行针对性注射治疗。结果‖形眉问纹占比为58．3％（35／60），U形眉间纹占比为26．7％（16／60），∩形眉间纹占比为11．7％（7／60），口形眉间纹占比为3．3％（2／60）。在注射后2～3d，开始出现肌肉收缩力减弱，2周左右效果达到顶峰，一般能够维持3～6个月。所有研究对象治疗均达到优秀效果。结论眉间纹可分为4种类型，采用分类型注射A型肉毒毒素治疗，效果的满意度较高。

Objective To guide the botulinum toxin injections, the types of glabellar wrinkles and the corresponding muscle contraction patterns of aesthetic seeking patients were classified. Methods Sixty aesthetic seeking patients between 20 to 65 ages were selected randomly, whose glabellar wrinkles and muscle contraction patterns were classified and analyzed. Targeted injections of botulinum toxin were taken only within the muscles related to the wrinkles. Results Type ＂ ‖ ＂ accounts for 58.3% （35/60）, type ＂ ∪ ＂ accounts for 26.7% （16/60）, type ＂ ∩ ＂ accounts for 11.7%（7/60）, and type ＂ 口 ＂ accounts for 3.3% （2/60）. Muscle contraction receded 2 or 3 days after injec- tion, reached optimum about 2 weeks, and then maintained 3 to 6 months. Higher satisfaction was obtained using classified injection methods. All objects achieved excellent results. Targeted injections of botulinum toxin on these muscles were able to achieve better clinical effects. Conclusions Using classified injection methods according to 4 types of aesthetic seeking patients＇ glabellar wrinkles can achieve higher satisfaction.
