Abstrakt: Background: Looking for an adequate solution for those patients who desire abdominal definition, but are not candidates for liposuction alone, Danilla developed a technique, using selective fat grafting into the rectus abdominis (RAFT) to increase the muscle volume in addition to selective liposuction and abdominoplasty to provide an optimal body contouring.
Objective: To determine whether intramuscular fat grafting in the rectus abdominis muscles leads to an increase in muscle thickness after one year.
Methods: This is a prospective cohort study, from a single center, carried out over 24 months (October 2021-September 2023). Sixty-two patients who underwent lipoabdominoplasty and RAFT, had their rectus abdominis cross section measured by ultrasound pre- and 12 months postoperatively. To compare the muscle thickness, a paired t-test statistic was used. A p-value of 0.05 was considered statistically significant (IBM SPSS Statistics V26).
Results: After 1 year, all 62 patients showed an increase in the size of the rectus muscle cross section, although only 58 (94%) had fat identifiable in the US. Preoperatively, the mean muscle cross-sectional size was 1, 4 cm. After RAFT, overall mean muscle cross section was 2, 3 cm (0, 9 cm/66.9% increase). When stratified into groups with and without identifiable fat, the group in which the graft remained showed greater increase than the group with no visible fat (69, 9% vs 19,6%).
Conclusion: The RAFT provided a significant increase in the muscle cross section in most cases after 1 year. The presence of fat is related to a statistically significant increase in the muscle compartment (pack).
