Abstract:
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.
