What affects the retention of breast volume after fat grafting?
"BMI, number of total autologous fat grafting procedures, pregnancy and lactation history, and preoperative volume were significantly associated with breast volume retention at 3 months"
"BMI, pregnancy and lactation history, and preoperative volume were significantly associated with breast volume retention at 6 months"
"Preoperative volume was the only factor that significantly increased breast volume retention at 6 months" - "The larger the preoperative breast volume was, the higher the volume retention was" because the "larger the breast is, the less pressure is exerted on the skin when the same amount of fat is injected" and "the larger the volume, the more likely it is that the injected fat is surrounded by tissue with blood flow at the recipient site, making survival easier for the injected fat."
"The volume retention increased with a larger BMI due to the abundance of donor fat, which makes harvesting good-quality fat easier, and the higher percentage of subcutaneous fat as a component of the breast, which provides more space for injections."
"As for the decrease in volume retention with an increasing number of total autologous fat grafting procedures, the skin may become less stretchable, increasing the pressure as the number of total autologous fat grafting procedures increases.
"The lower volume retention with a history of pregnancy and lactation could be due to a decrease in the quality of the recipient site or transplanted fat" and "volume retention is reportedly higher in women with prior breastfeeding experience"
is. In this study, we performed three-dimensional breast volume measurements before and after autologous fat grafting, calculated the volume and volume retention, and investigated factors that may affect volume retention. Methods: A total of 204 breasts that underwent autologous fat grafting by the....
