RESUMEN
Objective:To investigate the effect of liposuction combined with low-energy bipolar radiofrequency Bodytite in the treatment of facial and neck fat accumulation with unclear mandibular margin.Methods:From November 2020 to August 2021, 60 female patients with facial and neck fat accumulation and unclear mandibular margin, aged 19-45 (26.5±8.6) years, were included in the cosmetic surgery of Baiyu Medical Cosmetic Hospital of Chengdu High Tech Milan. The patients had the body mass index (21.3±3.2) kg/m 2. Liposuction was performed in the operation area of the opposite neck, and then radiofrequency skin tightening treatment was performed through the liposuction incision. The patients were followed up for 6 months to evaluate the postoperative effect. Results:The maximum liposuction volume of face and neck was 130 ml, the minimum liposuction volume was 26 ml, and the liposuction volume of face and neck was (43±9.8) ml. There was no scald reaction immediately after operation. The skin was flat, without unevenness, infection and other serious complications after 3 months of operation. Six months after operation, 57 patients were satisfied with the mandibular margin (95%) and 56 third-party plastic surgeons were satisfied (93%).Conclusions:Liposuction combined with low-energy bipolar RF Bodytite can solve the problem of skin relaxation while shaping the face and neck. It has obvious advantages in the plasticity of mandibular margin, and it is worthy of clinical application.
