Filler rhinoplasty and use of Metacrill® in the nasal tip: Case report and review of the literature

Abstract

Filler rhinoplasty is a procedure in which dermal fillers are used to alter the nasal profile without invasive surgery. There have been more than 150 fillers in the global market, though none of them are considered ideal. Polymethylmetacrylate (PMMA) has been used in medical practice for more than 50 years as a dermal filler and has been approved by the FDA for the correction of nasolabial folds. Once inyected, the PMMA micro spheres cause a foreign body inflammatory reaction, yet they cannot be removed by phagocytosis because of their large size, remaining unaltered in time. Granulation tissue and collagen fibers grow sorrounding and encapsulating the micro spheres. It is considered a permanent filler due to the remainance of the PMMA micro spheres in the skin. The nasal tip is an area easy to treat with fillers, though it must be managed with small volumes to avoid adverse reactions, mainly vascular compromise of the skin. We present the case of a patient who underwent a filler rhinoplasty with PMMA (Metacrill^®) in the nasal tip and a subsequent secondary revision rhinoplasty.
