what is the function of retroauricular
From a functional point of view, the retroauricular skin is an anastomotic bridge connecting the PAA (inferior pedicle) and the Superficial Temporal Artery (STA) through the Superior Auricular Artery (SAA, superior pedicle), which is a constant branch of the STA (Figure 1). Figure 1.ackground. The retroauricular skin has always been given much attention by the reconstructive surgeon for ear and face reconstruction because it is richly vascularised, as many anatomical investigations show, it is hidden behind the ear, its skin is very similar to that of ear and face.
