Revision and Repeat Procedures After Primary Aesthetic Gluteal Fat Grafting: A Systematic Review Poster

This systematic review evaluated whether current evidence permits estimation of the five-year cumulative incidence of corrective revision following primary aesthetic gluteal fat grafting. Seven studies comprising 1,555 patients were included in the qualitative synthesis. No included study provided a valid five-year revision estimate, and study-specific revision or repeat-procedure proportions ranged from 0.0% to 40.9%. Considerable variation in outcome definitions, follow-up duration, and ascertainment prevented a defensible pooled estimate. Among 48 classifiable procedure-level indications, additional volume or undercorrection was the most frequently reported reason for subsequent treatment (72.9%), followed by asymmetry or contour correction (20.8%). Current evidence therefore does not support a reliable five-year cumulative revision incidence after primary aesthetic gluteal fat grafting. Future studies require standardized definitions, complete longitudinal follow-up, and time-to-event reporting to provide meaningful long-term risk estimates for patient counseling.
