Researchers are studying whether MRI scans accurately measure gluteal tissue and skin-flap thickness before surgery to remove permanent synthetic fillers. Adults scheduled for elective excision of gluteal filler complications receive preoperative MRI, then surgeons measure the sa…

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…

Researchers are studying tissue removed during surgery from adults who developed complications after permanent gluteal filler injections. Two pathologists, working without knowing the clinical details, grade eight features including filler burden, inflammation, fibrosis, fat deat…

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…
