目的:研究A型肉毒毒素微滴注射方法改善下颌脂肪堆积外观，修饰下颌轮廓，实现下面部及颈部年轻化的临床效果。方法:回顾性分析2020年5月至2021年1月，中国医学科学院整形外科医院面颈整形美容中心收治的下颌脂肪堆积、下颌缘及颈部皮肤轻度松垂患者的临床资料。采用微滴注射方法，将稀释浓度为20 U/ml的A型肉毒毒素以1 cm为间隔，广泛、微量地注射于下面部和颈部的真皮层或真皮与肌肉浅层之间，单点注射0.6 U。注射范围以耳垂口角连线为上界，以两侧降口角肌为前界，两侧胸锁乳突肌前缘为后界，颈静脉切迹为下界。术后对患者进行随访，调查患者满意度，同时由第三方医师采用观察者总体美容改善评分法，对治疗前和随访时的患者照片进行评分。结果:共纳入25例患者，其中男10例，女15例，年龄(39.4±3.7)岁。随访1～2个月，平均1.3个月，患者主观满意度为96%(24/25)。第三方医师评估结果为：观察者总体美容改善分值为(3.08±0.64)分，96%(24/25)的患者达到改善标准。其中，1例患者出现注射后局部淤血，1周后恢复；4例主诉注射后疼痛、肿胀，24 h后可明显缓解。无口角偏斜、咀嚼无力、发声困难、面瘫、过敏或其他并发症。结论:应用A型肉毒毒素微滴注射可提升下颌脂肪堆积者下颌轮廓，改善臃肿松垂外观，修饰颈颏角，同时提升皮肤质地和改善颈部皱纹，治疗效果确切。“,”Objective:To study the clinical effect of Microbotox in improving mandibular fat accumulation, lifting mandibular contour and achieving lower face and neck rejuvenation.Methods:From May 2020 to January 2021, patients with mandibular fat accumulation and skin relaxation of mandible and neck were treated in Plastic Surgery Hospital, Chinese Academy of Medical Sciences. Multiple microdroplets of botulinum toxin type A was injected into the dermis or the interface between the dermis and the superficial muscle layer in lower face and neck. Botulinum toxin was diluted to 20 U/ml and injected with 0.6 U per point. The scope of Microbotox was demarcated by the line between earlobe-mouth corner as the upper border, the depressor anguli oris as the anterior border, the front edge of sternocleidomastoid muscle front edge as the posterior border, and the jugular notch as the inferior border. Treatment effect was evaluated postoperatively by the subjective satisfaction of patients and the accessment of a third-party physicians.Results:A total of 25 patients were included, including 10 males and 15 females, with the age of 39.4±3.7 years. The patient subjective satisfaction was 96%(24/25), and 96%(24/25) of patients received improved result , evaluated by a third-party physician. There were no serious complications except one case of local congestion and four cases of local pain and swelling, which could be relieved in a short time.Conclusions:Characterized by improving mandibular fat accumulation, lifting mandibular contour, reducing cervicomental angle, improving skin texture and neck wrinkles, Microbotox is effective and practical.
