Clinical application of autologous chyle fat transplantation in the correction of sunken upper eyelid

Aim: We investigated the clinical application of autologous chyle fat in the correction of sunken upper eyelid.Methods: From November 2020 to October 2021, 89 cases of correction with autologous chyle fat to sunken upper eyelid were performed (with or without other cosmetic procedures related to the eyes). An appropriate amount of fat was extracted from the superficial layer of the patient’s thigh and processed to chyle fat. About 0.5-2.8 mL of fat was injected under the orbicularis oculi muscle (roof-retro orbicularis oculi fat) or in the area where the orbital septal fat exists from the outer orbital margin of the upper eyelid.Results: In total, 59 patients were followed up for 1-11 months after surgery. No infection, necrosis, vascular embolism, upper eyelid lumpiness, fat calcification, or liquefaction occurred in all patients, while seven cases showed inadequate correction. The depression basically disappeared, the shape was relatively full, the youthfulness was greatly improved, and the satisfaction of patients was high during the follow-up period.Conclusion: The correction with autologous chyle fat to sunken upper eyelid showed little trauma, short recovery periods, and satisfactory results, and it is worthy of being popularized and applied more widely
