Novel Forehead Augmentation Strategy: Forehead Depression Categorization and Calcium-Hydroxyapatite Filler Delivery after Tumescent Injection

摘要

Background:The minimally invasive delivery of soft-tissue calcium hydroxyapatite fillers can ameliorate the appearance of forehead depressions and wrinkles. Forehead augmentations using fillers lead to fewer adverse events and to a faster recovery time than those using surgical procedures. However, many physicians avoid using them due to the risk of pain, intravascular injections, and embolisms that can cause skin necrosis and blindness. Strategy to address these issues includes pain reduction through tumescent solution before filler injection considering the vascular pathway. In addition, the strategy is also safer from embolism.
