ABSTRACT
Objective To explore the clinical effect of microgranular fat obtained by mechanical injection of autologous fat tissues in the treatment of lacrimal trough deformity.Methods Ten patients in this group were women,and the average age was 28 years.With tumescent technique,the thigh fat granules were aspirated;after the separation and purification using cell sorting screen,fat particles were obtained with uniform size and without fibrous tissue.Through mechanical pushing of the fat particles,the fat granules became chylomicron-like.The fat particles without fibrous tissue were injected into the superficial layer and deep layer of the orbicularis oculi muscle with depressed deformity.3-12 months after operation,the clinical efficacy was evaluated by doctors,patients and the third party.Results In 10 cases of lacrimal groove deformity,9 cases were transplanted once,and 1 case did twice.After 3 to 12 months follow-up the appearance of tear trough deformity was significantly improved,the texture of the ditch of eyelid and cheek skin was soft,and appeared young plump appearance.There were no complications,such as infection,hematoma,fat liquefaction,pigmentation and induration,and satisfactory results were obtained.Conclusions Ultrafine particles of fat are obtained using improved purification method in the treatment of lacrimal groove deformity,and the efficacy is satisfactory.
ABSTRACT
Objective To analyze factors of volume maintenance percentage after autologous fat grafting breast augmentation.Methods From March 2011 to December 2014,39 patients were included.Age,BMI,donor site,breast preoperative volume,whether or not application of Brava and water-jet-assisted liposuction were collected as variables.We performed multivariate regression and univariate regression analyses in a general linear regression model and multilevel linear regression model to identify significant factors.Results The mean percentage of volume maintenance was (34± 12) ％.In univariate regression analysis,rate of volume maintenace was decreased 3.3％ as increase of age per 5 years;Brava application increased volume maintenace,compared with donor sites of the back and abdomen 8.4％ (40.7％ vs 32.3％,P＜0.05),application of leg fat increased by 9.6％ of volume maintenace (39.1％ vs 29.5％,P＜0.05).In the multivariate regression analysis,Brava use increased volume maintenance of 6.2％ (P＜0.05);use of leg fat increased by 6.0 ％ of volume maintenace as compared with donor sites of the back and abdomen (P＜0.05).Conclusions The age,Brava,and donor site are significant impact factors to percentage volume maintenance in autologous fat graft breast augmentation.
