Treatment for Complications after Injection of Fillers into the Face: Two Case Reports

Abstract

　　Case 1 is a 34-year-old woman. According to her, she received hyaluronic acid injections for cheek augmentation at a clinic several years ago. She visited our department because induration, pressure and discomfort gradually developed at the injection site. Extirpation of the foreign substance was performed orally and percutaneously. At 10 months after the operation, her subjective and objective symptoms had improved.
　　Case 2 is a 39-year-old woman. Approximately 15 years ago, filler was injected into her nose root for nose augmentation at a clinic. Approximately 2 months prior to consultation, she developed noticeable protrusion of the nasal root area. Diagnosed as foreign body granuloma, we performed extirpation surgery twice percutaneously. She was satisfied with the excellent result.
　　There are many reports about complications, such as redness, swelling, induration and scarring, among patients who receive fillers. Such fillers are classified into absorbable and non- absorbable, and our cases may have involved fillers containing non-absorbable materials. Non-absorbable fillers have a high rate of complications, and once they develop, treatment is difficult, and post-operative deformity and scarring are unavoidable. Non-absorbable fillers should be injected into the face with caution and long-term follow-up is necessary.
