This trial tests whether a structured MRI reading method helps surgeons see the full extent of permanent filler complications in the buttocks better than the standard approach. Adults who had gluteal filler injections and are scheduled for surgery will get both types of MRI repor…

This study examines 20 adult cadaveric lower limbs to map where motor branches of the tibial and peroneal nerves enter their target muscles. Researchers measure each entry point relative to leg length and calculate probability intervals. The goal is to provide quantitative anatom…

This study compares two electrocautery tips—blunt and Utah—to see which causes less thermal damage to fat, fibrotic, and muscle tissue. Tissue samples are taken from patients undergoing surgical removal of gluteal biopolymers (injected fillers). The tissue is cut in the lab using…

This randomized clinical trial will compare indocyanine green fluorescence angiography-guided assessment with standard clinical assessment of gluteal flap perfusion during removal of permanent synthetic fillers. Participants will be assigned 1:1 to fluorescence-guided or standard…

This prospective biospecimen cohort will collect and analyze tissue from adults undergoing clinically indicated surgery for gluteal permanent synthetic filler disease. Two blinded pathologists will score foreign material burden, inflammation, fibrosis, necrosis, vascular and lymp…

This prospective agreement study will compare preoperative MRI measurements with direct surgical measurements in adults undergoing removal of gluteal tissue affected by permanent synthetic fillers. MRI will estimate affected-tissue dimensions and residual skin-flap thickness at p…
