RESUMEN
Objective To observe the clinical effects of external tissue expansion assisted lipotransfer for temple depression augmentation.Methods A total of 18 cases of temple depression wore the a vacuum-based cupping cup device for recipient-site preconditioning for 1-3 months before fat injection.Results Temple soft tissue can pinched easily after expansion,fat injection ranged from 12-16ml per site,the temple depression were augmented and the sculpted appearance were improved obviously after 1to 12 months follow-up,there were no complications such as nodules,masses,alopecia or cysts occurred.Patient satisfaction was assessed and the VAS score was (7.8.± 1.4).Conclusions The addition of temple region expansion before fat injection can improve the skin compliance,increase the recipient-site volume,enhance fat graft placement and higher graft survival rates,demonstrating a high safety and efficacy procedure.
RESUMEN
Objective@#To investigate the application and therapeutic effect of external tissue expansion-assisted autologous fat grafting for delayed breast reconstruction.@*Methods@#Patients began wearing the BRAVA negative pressure system 8 hours a day for recipient tissue expansion for one month before the fat grafting procedure. After fat grafting, BRAVA was recommended to be worn 8 hours a day from postoperative 48 hours to one month. The interval of each fat grafting procedure was 2.5 to 3.0 months. The procedures were repeated until the completion of breast reconstruction. Water-jet assisted liposuction and subcutaneous release of scars were also performed during surgery.@*Results@#From January 2013 to November 2016, 29 patients were followed up for 12 to 58 months, with average of 31.6 months. 28 patients completed the external tissue expansion-assisted autologous fat grafting breast reconstruction. Completion required 1 to 6 procedures, with average of 3.4 procedures. The total initial fat fill volume for each breast was ranged from 200 to 1 000 ml, with average of 583.7 ml. The initial fat fill volume for each breast was ranged from 92.5 to 243.7 ml per operation, with average of 173.8 ml. One patient underwent latissimus dorsi myocutaneous flap breast reconstruction after 3 fat grafting procedures. 8 patients completed the inframammary fold reconstruction, 3 patients underwent breast lift, 1 patient underwent lipofilling augmentation for the contralateral side. Postoperative satisfaction rate was 82.8% in patients and 75.9% in surgeon. Complication statistics: 5 cases of palpable nodules which recognized as fat necrosis (17.2%), one case of nontuberculous mycobacterial infection (3.4%) and one case of locoregional cancer recurrence (3.4%).@*Conclusions@#External tissue expansion-assisted autologous fat grafting is a minimally invasive procedure for breast reconstruction. Satisfactory results could be obtained for most of the patients who would like to choose fat grafting and have enough fat deposit in other parts of the body.
RESUMEN
Objective To observe the clinical effects of autologous fat injection augmentation with external tissue expander.Methods 26 cases wore the Brava device,a bra-like vacuum-based external tissue expander for 4 weeks before autologous fat injection augmentation.Patients resumed Brava wear for 14 more days after fat injection.Results 26 women had a mean augmentation volume at 3 months of 76 ml per breast after single fat injection.Follow-up ranged from 1 month to 12 months.There were no complications such as nodules,masses,or cysts occurred.Patient satisfaction was as sessed:25 cases (95.6 ％) were satisfied with the cosmetic results.Conclusions The addition of Brava expansion before autologous fat grafting leads to significantly larger breast augmentations,with more fat graft placement,higher graft survival rates,and minimal graft necrosis or complications,demonstrating high safety and efficacy for the procedure.
