Abstract：Objective To investigate the clinical effect and safety of zoned low negative pressure liposuction combined with low energy bipolar radiofrequency and granular fat filling in mid-lower facial rejuvenation.Methods From October 2019 to April 2023,32 patients(64 sides)with nasolabial depression with mid-lower facial fat accumulation and skin relaxation were retrospectively analyzed.The patients were followed up for 6 months after receiving bucaal low negative pressure liposuction combined with low energy bipolar radio frequency,nasolabial groove and lateral buccal depression granule fat filling treatment.The postoperative effect was evaluated by doctors and patients respectively,and the postoperative complications were counted.Results Among the 32 patients,the mean body mass index was(22.2±1.6)kg/m2,the mean fat extracted per zone was(3.6±2.4)ml,and the mean radiofrequency energy per zone was(1.6±0.5)kJ.After 6 months of follow-up,the patient's facial contour was smooth,skin elasticity was enhanced,and wrinkles were reduced.The average score on the 6-point grading scale(GGS)was decreased from(3.5±0.7)to(1.4±0.8)(P<0.05),the average facial laxity rating scale(FLR)score decreased from(5.3±0.6)points to(2.4±0.5)points(P<0.05),the self-rated satisfaction rate of patients was 90.6%.Postopera-tive Ⅰ degree skin scald occurred in 1 case,and oral Angle was slightly skewed in 2 cases in the early stage after surgery.The symp-toms disappeared completely after 3 to 12 weeks of conservative treatment,and no complications occurred in the remaining patients.Conclusion The low negative pressure liposuction combined with low energy bipolar radiofrequency and particle fat filling can effectively improve the fat accumulation in the cheek,the aging of the"law line"in the nasolabial groove and the loose sag in the mid-lower face,which is a safe and reliable treatment method worthy of promotion.
