COMPLICAÇÕES DA RINOMODELAÇÃO COM ÁCIDO HIALURÔNICO: UMA REVISÃO

Nonsurgical rhinoplasty with hyaluronic acid (HA) fillers is a minimally invasive aesthetic procedure that is increasingly employed as a less invasive alternative to surgical rhinoplasty for correcting minor nasal defects. Although it enjoys a high satisfaction rate and few immediate adverse events, it is not free of complications, which can range from mild, transient reactions to rare but serious events. This article reviews the principal complications associated with nasal HA fillers, categorizing them as mild (edema, erythema, localized pain, and bruising); vascular (ischemia, tissue necrosis, and arterial embolism with risk of blindness); inflammatory–immunological (nodules, granulomas, and persistent intermittent late-onset edema – PILE); infectious (e.g., cellulitis, abscesses, and biofilm formation); and aesthetic (asymmetries, overcorrection, and filler migration). For each category, the pathophysiology, clinical presentation, and recommended management are discussed. A thorough understanding of nasal anatomy, mastery of safe injection techniques, and readiness to manage complications are essential for ensuring patient safety and satisfactory outcomes.
