ABSTRACT
The blood supply to the auricle derives from branches of the external carotid artery: the posterior auricular artery from the external carotid artery, the anterior auricular artery from the superficial temporal artery, and the mastoid branch from the occipital artery. The supply of the external auditory canal comes from the posterior auricular artery, the internal maxillary artery, and the superficial temporal artery. The veins accompany the corresponding arteries.
