The international encyclopaedia of surgery; a systematic treatise on the theory and practice of surgery . ed. It then curves over thebody of the lower jaw, close to the anterior inferior angle of the massetermuscle, ascends to the angle of the mouth, and thence to the inner canthus ofthe eye, where it is named the angular artery. Over the buccinator muscleits course is tortuous to accommodate itself to the movements of the jaw. Below the jaw, it passes under the digastric and stylo-hyoid muscles; onthe body of the jaw it is covered by the skin, superficial fascia, and platysmamyoides, and lies on the periosteum in a groove which is found at the junc-tion of the posterior third with the anterior two-thirds of the body of thebone. The facial vein runs on its outer side. The groove just mentioned isthe point usually selected for the deligation of the artery. Operation.—Having recognized the pulsations of the artery, make an in-cision one inch in length, along its course over the body of the lower jaw, asjust described (Fig. 476), through the skin, superficial fascia, and platysma Fig. Ligation of the facial and temporal arteries.

LiaATiON OF THE TEMPORAL Artery.—This artery is the more superficialof the two terminal branches of the external carotid. It commences inthe substance of the parotid gland, opposite the meatus auditorius externus,ascends almost longitudinally over the root of the zygoma, and, at one inchand a half or two inches above the zygomatic arch, divides mto the anteriorand posterior temporal branches. Operation.—Having determined the position of the artery by its pulsations,make an incision through the skin, one inch in length, at a point above thezygoma and in front of the ear, then divide the dense connective tissue on
