Delayed onset filler complication: Two case reports and literature review

Abstract

Soft tissue augmentation by fillers has become a popular cosmetic tool to offer rejuvenation and aesthetic improvement. Its results are comparable to those previously achieved only by plastic surgery. However, marked increase of filler procedures is associated with a great number of complications. Complications associated with filler injection might have early onset (within days) or late onset (after weeks to years). Delayed complications include infections, foreign body granulomatous reaction, migration of filler material, persistent discoloration, and scarring. Here we report two cases of delayed complications: one case of foreign body granuloma with migration and one case of acute inflammation involving a quiescent granuloma.
