DE ARAZOZA BORGES, Diana; NORIEGA RODRIGUEZ, Daniel y GONZALEZ GARCIA, Sergio. Survival of fat graft in gluteal lipotransfer. Rev Cubana Cir [online]. 2023, vol.62, n.3 Epub 01-Sep-2023. ISSN 1561-2945.
Introduction:
Buttock augmentation aims to achieve a more youthful appearance and contour; as well as creating the ideal proportion between waist and hips. This can be achieved by lipoinjection, although in this case there are controversies regarding the viability of the injected tissue and the survival of the fat.
Objective:
To determine the percentage of autologous fat graft survival and its relationship with the injected volume in patients undergoing gluteal fat transfer.
Methods:
An observational, descriptive, longitudinal and prospective study was carried out, with a sample of 44 patients undergoing gluteal lipotransfer, in the plastic surgery service of the Dr. Miguel Enriquez Clinical Surgical Teaching Hospital, in the intermediate period between March 2018 to June 2021.
Results:
The study shows that through ultrasound and formulas, the average volume and height of fat in the buttocks doubles in the immediate postoperative period, decreasing in the late postoperative period, without reaching preoperative values. Furthermore, it’s established that about the mean volume of autologous fat grafted to the buttocks survives definitively in the late postoperative period. In addition, it was established that the relationship between the infiltrated volume and the survival of the autologous fat graft is inversely proportional, the greater the volume, the less its survival.
Conclusions:
Only half of the volume of autologous fat injected into the buttocks survives definitively, and the survival of the fat is inversely proportional to the volume injected.
