The present manuscript is a clinical case report in which antimicrobial photodynamic therapy (aPDT) - using a low-power laser (660 nm) associated with methylene blue photosensitizer (0.01%) - was considered for treating a case of complication after implantation of spiculated polydioxanone (PDO) threads, an aesthetic procedure worldwide performed in facial cosmetic non-surgical procedures. A 72-year-old female patient presented an infection in the face region where the PDO thread was implanted (mandible angle). After divulsion and local drainage, it was decided to associate aPDT using a low-level laser associated with a 0.01% methylene blue photosensitizer. Two sessions of aPDT were performed - on sequential days - and within 48 hours the region was dry and without signs of secretion. The use of aPDT seems to be a promising and effective option in cases of infections after implantation of PDO threads, consisting of a safe technique, of low execution complexity and without adverse effects.
本手稿是一份临床病例报告，其中考虑使用抗菌光动力疗法（aPDT）——采用与亚甲蓝光敏剂（0.01%）联合使用的低功率激光（660nm）——来治疗一例植入带刺聚二氧六环酮（PDO）线后的并发症，这是一种在全球面部美容非手术程序中进行的美容手术。一名72岁女性患者在植入PDO线的面部区域（下颌角）出现感染。在进行撕脱和局部引流后，决定采用与0.01%亚甲蓝光敏剂联合使用的低水平激光进行aPDT。连续两天进行了两次aPDT治疗，48小时内该区域干燥且无分泌迹象。在PDO线植入后发生感染的病例中，使用aPDT似乎是一种有前景且有效的选择，它是一种安全的技术，执行复杂性低且无不良反应。
