泪沟畸形的分类及治疗方法多样，求美者与整形医师常难以选择。明确泪沟的分类对于准确、便捷地选择治疗方案十分重要。目前泪沟畸形的分类多基于外观，基于成因的分类较少。本文提供了一种新的分类角度，根据成因将泪沟分为衰老所致的后天性泪沟，和眶下颧骨复合体发育不全所致的先天性泪沟，后者又分为青春期出现的非年龄相关型、30岁后出现的年龄相关型。同时也根据分类提出了治疗策略，后天性泪沟和严重的先天性泪沟患者首选基于手术的治疗方法，其余患者尤其是年轻患者应首选以透明质酸和自体脂肪填充为主的微创治疗。随着年轻求美者的增加，微创治疗策略应被重视，其并发症有待于进一步研究解决。“,”The classifications and treatments of tear trough deformity are various, which is difficult for patients and plastic surgeons to choose. Clear classifications of tear trough is very important for accurate and convenient selection of treatment. At present, the classification of deformity is mostly based on appearance, and rarely based on etiology. We believe that the tear trough can be divided into acquired ones, caused by aging, and congenital tear trough, caused by hypoplasia of infraorbital zygomatic complex. The latter can be further divided into non age-related type in adolescence and age-related type occurring after 30 years old. And we proposed the corresponding treatment strategies according to the classification at the same time. The patients with acquired and severe congenital tear trough should firstly choose surgery. For the rest patients, especially young patients, minimally invasive treatment such as hyaluronic acid and autologous fat filling should be the primary choice. With the increase of young people seeking beauty, minimally invasive treatment strategy should be paid attention to, and its complications need to be further studied and solved.
