Abstract：
BACKGROUND: Autologous fat grafting is a common treatment for tear trough deformities. This procedure involves a potential complication of fat nodule formation, leading to abnormal bulging of the lower eyelid. However, limited information exists about this complication, and an effective treatment is lacking. The present study aimed to present a novel surgical approach for the removal of fat nodules caused by autologous fat grafting in the tear trough.
METHODS: This retrospective study included 33 patients who underwent surgery for the removal of fat nodules formed after autologous fat grafting. The procedure was performed using a conjunctival approach, allowing exposure and removal of all fat nodules in the anterior septal space, with the method adapted according to the severity of the deformity.
RESULTS: A total of 66 eyelids were treated surgically, including 30 (45.45%) with mild nodular deformity, 23 (34.85%) with moderate nodular deformity, and 13 (10.70%) with severe nodular deformity. A second surgical procedure was required on 3 eyelids (4.56%). The main complications of the surgery were conjunctival congestion (21.21%), and localized depression (18.18%), bruising (12.12%). Among the patients, 29 (87.88%) were satisfied and 4 (12.12%) were dissatisfied with the treatment results.
CONCLUSIONS: Conjunctival approach surgery is an effective method of removing fat nodules formed after autologous fat grafting in the tear trough, with good results and high levels of patient satisfaction. This approach enables the effective management of a common complication of autologous fat grafting and may enable the wider application of autologous fat grafting in the periorbital region.

摘要：
背景：自体脂肪移植是泪槽畸形的常用治疗方法。该手术涉及脂肪结节形成的潜在并发症，导致下眼睑异常隆起。然而,关于这种并发症的信息有限，缺乏有效的治疗方法。本研究旨在提出一种新的手术方法，用于去除泪槽中自体脂肪移植引起的脂肪结节。
方法：这项回顾性研究包括33例患者，这些患者接受手术切除自体脂肪移植后形成的脂肪结节。该程序是使用结膜方法进行的，允许暴露和去除前间隔间隙中的所有脂肪结节，根据畸形的严重程度调整方法。
结果：总共66个眼睑接受了手术治疗，其中轻度结节畸形30例(45.45%),23例（34.85%）伴中度结节畸形，严重结节畸形13例(10.70%)。需要对3个眼睑进行第二次外科手术（4.56％）。手术的主要并发症为结膜充血(21.21%),和局部抑郁症（18.18%），瘀伤（12.12%）。在患者中,对治疗结果满意29例(87.88%),不满意4例(12.12%)。
结论：结膜入路手术是去除泪槽自体脂肪移植后形成的脂肪结节的有效方法，结果良好，患者满意度高。这种方法可以有效地管理自体脂肪移植的常见并发症，并且可以使自体脂肪移植在眶周区域的更广泛的应用。
