Abstract:
The anterior tympanic artery, a branch of the maxillary artery, ascends through the retroarticular region dividing into anterior branches that spread through the posterior part of the temporomandibular joint, and posterior branches that contribute to the vascularization of the external acoustic meatus and the tympanic cavity. The arrangement of the anterior tympanic artery was studied bilaterally in 18 adult cadavers. In some cases, the anterior tympanic artery branches off from the superficial temporal artery. The relationships of the anterior tympanic artery with the posterior part of the temporomandibular joint were analyzed.
