【摘要】：目的:介绍一种微创中下面部除皱术——可吸收整形提升带(微拉美)联合PPDO(可吸收锯齿线)改善鼻唇沟过深、皮肤及面部深层软组织松弛下垂的提拉固定术,为新型可吸收生物除皱材料在微创除皱术中的临床应用提供理论基础和实践依据。方法:根据诊断标准、纳入标准及排除标准选取要求行中下面部除皱术的患者共116例,其中A组(58例)行传统切口高位SMAS(表浅肌肉筋膜系统)除皱术,B组(58例)行微拉美联合PPDO的微创除皱术。将两组受试者术后3个月、6个月的皱纹严重程度评分和中下面部整体美容效果改善分级数据进行收集整理后,行统计学分析比较,得出结论。结果:随访3个月、6个月两组轻中度衰老患者中下面部年轻化效果改善差别无统计学意义(P0.05),A组重度衰老患者中下面部年轻化效果改善要好于B组,差别有统计学意义(P0.05)。结论:对于轻中度皱纹的患者,微拉美联合PPDO的微创除皱手术效果与传统除皱手术效果无差异,且具有手术时间短、切口小、并发症少等优点,可吸收整形提升带使面部深层软组织解剖复位的同时还能增加局部软组织容量,PPDO在吸收过程中,刺激皮肤胶原蛋白的生成,使皮肤真皮层增厚收紧,达到光亮紧致的效果。作为一种新型微创除皱术,有一定的临床推广价值。但对于重度皱纹的患者传统手术中下面部年轻化改善效果优于微拉美联合PPDO微创除皱术。
[Abstract]:Objective: to introduce a minimally invasive lower facial rhytidectomy-absorbable plastic lifting band (micro-Latin America) combined with PPDO (absorbable serrated line) to improve the depth of nasolabial sulcus, skin and deep soft tissue flabby and saggy fixation. It provides a theoretical and practical basis for the clinical application of new absorbable biodegradable materials in minimally invasive rhytidectomy. Methods: according to the diagnostic criteria, inclusion criteria and exclusion criteria, 116 patients with middle and lower facial rhytidectomy were selected. Group A (58 cases) were treated with traditional incision high position SMASA (superficial muscle fascia system) and group B (58 cases) with micro-Latin America combined with PPDO. The score of wrinkle severity and the classification data of overall cosmetic effect of middle and lower face were collected and sorted after 3 months and 6 months after operation in the two groups, and then statistical analysis and comparison were carried out, and the conclusion was reached. Results: following up for 3 months, there was no significant difference between the two groups in the improvement of the lower part rejuvenation effect in the patients with mild and moderate aging. There was no significant difference between the two groups. The improvement of the lower part in the patients with severe aging was better than that in the B group, and the difference was statistically significant (P 0.05). Conclusion: for patients with mild and moderate wrinkle, the effect of micro-Latin America combined with PPDO is not different from that of traditional wrinkle removal, and it has the advantages of short operation time, small incision, less complications and so on. Absorbable plastic lifting band can also increase the local soft tissue capacity and stimulate the formation of collagen in the process of absorption, which can make the skin dermis thickened and tighten, and achieve the effect of bright and tight. As a new type of minimally invasive rhytidectomy, it has certain clinical value. But for the patients with severe wrinkles, the effect of lower part rejuvenation was better than that of microLatin America combined with PPDO minimally invasive rhytidectomy.
