Introduction

       Injectable fillers have been increasing in popularity for facial rejuvenation in recent years. One of the most challenging areas for filler injection is the lower eyelid. The area undergoes  many anatomic changes as the face ages.Many kinds of fillers and injection techniques  have been proposed, but the results are variable.4 We propose an alternative, simple, and  effective filler injection method in this area for Asian patients.

       近年來，填充注射技術(shù)在面部年輕化方面越來越受歡迎。填充注射最具挑戰(zhàn)性的領(lǐng)域之一是下眼瞼。隨著面部年齡的增長，下眼瞼區(qū)域發(fā)生了許多解剖學(xué)變化。以往研究提出了多種填充材料和注入技術(shù)，但結(jié)果各不相同。我們旨在探索為亞洲患者提出了一種簡單有效的填充物注射方法。

METHODS

       Any patient who has tear trough deformities, infra-orbital hollows, nasojugal grooves, dark eye circles, as well as mild eyebags is a potential candidate for this method. Our filler choice is injectable poly-D,L-lactic acid (PDLLA; AestheFill; REGEN, Seoul, South Korea). PDLLA must be reconstituted with sterile water for injection (SWFI) before administration. When the patient's troughs, grooves, or volume deficit are class II to III, 3-4 mL of SWFI and 1 mL of  are used. When the deficits are class I, 5-7 mL of SWFI and 1 mL of  are used. With fanning injection technique, a wide region that covers all the deficits is evenly injected. The depth is under the dermis layer. Total amount of filler injection is not more than 2 mL on each side.

       本研究面向包含有淚溝畸形、眶下凹陷、鼻頰溝、黑眼圈以及輕度眼袋的患者。我們選擇的填充物是可注射的聚D,L-乳酸（PDLLA; 韓國）。PDLLA在給藥前必須用無菌注射用水（SWFI）進行復(fù)配。當病人的凹陷、溝槽或容積不足為II至III級時，使用3-4毫升SWFI和1毫升。當凹陷等級為I級時，使用5-7毫升的SWFI和1毫升的。采用扇形注射技術(shù)，均勻地注射覆蓋所有容積缺失的廣泛區(qū)域。其深度在真皮層之下。每側(cè)填充物的總注射量不超過2毫升。

RESULTS

       Since 2019, we have injected more than 100 patients by following these steps in Taiwan. The level of patient satisfaction is high. Only some mild and transient post-injection complications such as edema, erythema, and ecchymosis were found.

       自2019年以來，本研究團隊已經(jīng)按照這些步驟注射了100多名患者?；颊叩臐M意程度很高。僅發(fā)現(xiàn)一些輕度和一過性的注射后并發(fā)癥，如水腫、紅斑和瘀斑。

CONCLUSION

       We propose an alternative, simple and effective method for non-surgical lower eyelid rejuvenation for Asian patients. However, anyone who wants to perform this procedure should be well-trained and knowledgeable about the anatomy, product and procedure to prevent the adverse events

       本研究為亞洲患者提出了一種替代性的、簡單而有效的非手術(shù)下瞼年輕化方法。然而，任何想進行這種手術(shù)的人都應(yīng)該接受良好的培訓(xùn)，并對解剖學(xué)、產(chǎn)品和注射方法有所了解，以防止出現(xiàn)不良事件。
