BACKGROUND: This retrospective study evaluated the anatomical distribution of the superficial temporal artery (STA) in supply of the temporoparietal fascial (TPF) flap for use in patients with unilateral microtia undergoing reconstruction. We aimed to determine whether embryologic arrest of pharyngeal arch development would lead to aberrant STA, which impedes reliable harvest of the TPF flap in patients requiring microtia repair.
METHODS: CT angiograms (CTAs) and 3D reconstruction of the face and neck of 41 patients with microtia, aged 6-21 years, were examined. The number of STA branches, branching pattern, vessel diameter, and the presence or absence of the external auditory canal atresia were documented.
RESULTS: The STA crosses the zygoma on average 4 mm more anterior to the porion (anterior-inferior lip of the tympanic part of the temporal bone) on the side with microtia compared to the nonmicrotia side. There were no statistically significant differences between vessel caliber or STA branches between the two sides.
CONCLUSION: The STA is anatomically reliable for inclusion in TPF flaps, which is used for auricular reconstruction in patients with microtia. A TPF flap can be safely harvested by the routine technique; however, surgeons should be cognizant of the STA coursing more anteriorly on the microtia ear.
