Overview
A sad facial appearance can be treated with neuromodulator injections into the Depressor anguli oris muscle. Upon relaxation of this muscle, the downwards pull of the oral commissure becomes less and the facial elevators can increase their upwards pull resulting a happier facial expression. This video explains how to use the Marinette lines as a reliable clinical landmark to achieve safer and superior clinical outcomes.
