title: The arterial supply of the temporalis muscle.
abstract: Owing to the diverse applications of the temporalis muscle in reconstructive surgery, the study of its arterial supply is becoming an issue of great importance nowadays. The material of the present study consisted of 44 specimens, four obtained from two stillbirths and 40 dissected from 20 embalmed cadavers after injecting the external carotid artery with lead oxide solution. Direct branches from the second part of the maxillary artery and the middle temporal artery proved to be constantly furnishing the muscle from its superficial and deep surfaces. The muscular branch of the middle temporal artery supplied the middle and posterior thirds of the superficial surface and the posterior third of the medial surface of the muscle. The superficial temporal artery participated in supplying the muscle from its lateral surface, while the anterior and posterior deep temporal arteries lay deep to the anterior and the middle thirds of the muscle, respectively. The temporal branches of the middle meningeal artery anastomosed with the deep temporal arteries, thereby contributing to the supply of the temporalis muscle. An arterial pedicle arising from the third part of the maxillary artery constituted an additional supply in 9.1% of the specimens, providing an additional arterial pedicle for temporalis-muscle-flap elevation.
