Complications associated with the injection of soft tissue fillers arise in most cases from injector inexperience or use of unapproved products. However, injection injuries to relevant anatomic structures, such as nerves and vessels, can occur even in the hands of experienced injectors while using US Food and Drug Administration (FDA)-approved products.
The incidence of vascular occlusion following soft tissue injection may be as high as 3 in 1000 . In May 2015, the US FDA warned that the unintentional injection of soft tissue fillers into the blood vessels of the face can result in rare but serious adverse effects and advised providers without appropriate training or experience to refrain from injecting soft tissue fillers .
This topic will review the relevant vascular anatomy of the face and the danger zones at risk of vascular compromise from injection of soft tissue filers. The types and clinical use of injectable soft tissue fillers are discussed separately. The anatomic danger zones for cutaneous surgery of the head and neck are also reviewed separately.
