Objective:To observe the therapeutic effect of collagen complant filling in the correction of lacrimal groove deformity.Methods:Twenty-five patients with lacrimal groove deformity in our hospital from July 2018 to October 2019 were injected with collagen complant under local nerve block anesthesia or local topical anesthesia to improve local aging. The effects and adverse reactions after injection were evaluated.Results:The lacrimal groove depression was significantly improved in twenty-five patients in this study after injection of collagen implant. The lower eyelid to zygomatic-cheek region presented a natural and smooth, youthful profile curve. The shadow of lacrimal sulcus and palpebral sulcus depression and the pigmentation of lower eyelid were obviously improved. All the patients had mild swelling and skin reddening after the injection immediately. Two patients had local bruise. One patient had a small local strip bulge after injection. The effective rate was 88%. The overall satisfactory rate was 92%. During the follow-up for 3 months, the effect remained satisfactory within 1 month.Conclusions:Collagen complant filling can improve lacrimal groove deformity and achieve the goal of facial rejuvenation.
