RESUMEN
ABSTRACT: The use of hyaluronic acid (HA) fillers in lip augmentation represents today 1 of the most widely used nonsurgical aesthetic procedures in the world. Regarding the severe complications are rare, insufficient professional experience for recognizing signs of vascular impairment and inadequate technique could lead to severe lip skin necrosis complications. Several of existing treatment protocols in the literature to treat vascular complication are mainly based on the use of hyaluronidase. Nevertheless, there is no consensus on dosage, interval between doses and complementary protocol among the aforementioned studies. This case aims to present a conservative approach for the clinical management of serious vasculature complications with HA injection. A high dose of hyaluronidase(11500 IU) with additional multimodal treatment was performed to the upper lip, nasolabial fold, and nose that successfully reversed a vascular complication process. The present findings suggest that the use of high doses of hyaluronidase with the complementary protocol used herein might be a promising approach in the treatment of severe vascular complication in the lips caused by HA filling.
