Abstract

Background
Breast augmentation is the most common surgical intervention among women. However, concerns persist regarding the use of autologous fat grafting for breast augmentation in underweight females.
Objective
This retrospective study aimed to evaluate the efficacy and safety of autologous fat grafting in breast augmentation for underweight females (body mass index [BMI] <18.5 kg/m 2 ).
Methods
This study included 53 underweight patients who underwent autologous fat grafting for breast augmentation. Standardized protocols were followed, and comprehensive data regarding post-treatment complications were recorded. Volumetric and subjective evaluations were conducted to assess outcomes.
Results
The average age of the patients was 31.6 years, with an average BMI of 17.7 kg/m 2 and body fat percentage of 21.4%. The average volume of aspirates obtained was 1,410 ml, and each breast received an average injection volume of 295 ml fat. Routine postoperative assessments revealed fat necrosis of 3.7%. The mean volume retention of the grafted fat was 69.9% at the one-year mark, and the overall patient satisfaction rate was 94.3%.
Conclusion
Autologous fat grafting can be challenging in underweight women because of limited fat reserves and tight breast skin. Strategies such as ultrasound-assisted liposuction and precise injection techniques can overcome these challenges. The study suggests that a BMI <18.5 kg/m 2 is not a contraindication for autologous fat grafting in breast augmentation. Autologous fat grafting can be effective and safe for breast augmentation in underweight women, with satisfactory results and minimal complications.
