Background: In recent years, fillers procedures with hyaluronic acid (HA) have grown significantly. Despite HA relative safety, the number of cases of complications after injections has grown, and in many of which, we are not aware of or have little control over.
Aims: In this article, the authors describe a new adverse reaction after filling with HA injection, the sterile abscess.
Patients/methods: We present eight patients with similar clinical, laboratory, and ultrasound characteristics for sterile abscess and report a new therapeutic modality for it.
Results: All cases were treated with "Munhoz-Cavallieri Lavage Protocol" procedure with complete resolution.
Conclusions: "Munhoz-Cavallieri Lavage Protocol" serves as a guideline in diagnosis and management of sterile abscess.
Keywords: complications; fillers; hyaluronic acid; sterile abscess.
