Overview
The emergence of a subdermal cannula-based injection technique prompted the development of a superficial = subdermal needle-based injection technique to treat the tear trough deformity. Despite of high technical risk, this injection technique is becoming more and more popular. In this video, the superficial = subdermal needle injection technique from an inferior injection approach is simulated.
