Low Negative Pressure Combined With Supertumescence Microliposuction As a New Method For Repairing Facial Fat Overfilling: A Case Series of 32 Patients.

BACKGROUND Face fat overfilling sometimes occurs and is very difficult to repair unfortunately. OBJECTIVES The authors report their first experience of micro-liposuction with low negative pressure combined with super-tumescence (LNPST) in a case series of 32 patients. METHODS The LNPST micro liposuction was performed in 32 patients aged 22 to 41 (mean, 29.6±4.9) years with facial overfilling. Two independent plastic surgeons intraoperatively monitored and recorded discomfort and bleeding using a grading system. All patients were followed up for haematoma within 1 week postoperatively and for skin numbness and muscle paralysis at 1 week and 3 months postoperatively. In addition, 6 months postoperatively, patient satisfaction with the postoperative aesthetic effects was analysed by Face-Q. RESULTS All patients successfully completed the operation under local anaesthesia. The intraoperative discomfort and blood-loss scores were 1.69±0.62 and 1.22±0.41, respectively. The haematoma score was 1.13±0.34 within 1 W [other scores: postoperative skin numbness (1 W: 1.96±0.62; 3 M: 1.13±0.33) and postoperative muscle paralysis (1 W: 1.22±0.51; 3 M: 1.0±0)]. Overall, neither skin necrosis nor serious complications requiring revision surgery occurred. Seventy-two percent of the patients (n = 23) answered the Face-Q questionnaire (21.8±1.7), covering satisfaction with the outcome score into a standard score (81.7±15.1, from 0 to 100), which verified the high satisfaction rate. CONCLUSIONS LNPST technology is a safe and effective method for facial-fat-overfilling repair, with less bleeding, less neuro injury, fewer complications and high patient satisfaction.
