    in the root of the neck. Dorsal to the trachea, in its whole length, lies the esophagus, which in this part of its course inclines to the left. On either side are the great vessels and nerves of the neck, and the lobes of the thyroid gland. The inferior laryngeal nerve lies in the angle between the esophagus and trachea. Within the thorax the trachea lies in the mediastinum, enveloped in loose areolar tissue and fixed through strong fibrous connections with the central tendon of the diaphragm. The innominate artery and the left common carotid are at first ventral and then lateral as they ascend, while the left innominate vein and the remains of the thymus are further ventralward.

(Rauber-Kopsch.) The arotic arch is in contact with the ventral surface of the trachea near the bifurcation. On the right side are the vagus nerve, the arch of the vena azygos, the superior vena cava, and the mediastinal pleura; on the left, the arch of the aorta, the left subclavian artery, and the inferior laryngeal nerve. A large group of bronchial lymph-glands [lymphoglandulse bron- hiales] lies caudal to the angle of bifurcation. The esophagus is dorsal and to the left. Clinical aspects.—In doing a tracheotomy the operator must have in mind the important relations of the larynx and the cervical portion of the trachea, especially the large vessels and nerves lateral to the midsagittal plane of the trachea and the esophagus dorsally. A high tracheotomy above the isthmus of the thyroid gland should be abandoned. In its place a tracheotomy should be made as low as possible and the incision should never be made through the first ring of the trachea; the 3rd, 4th, and 5th tracheal rings should be incised. It is a rule now that the cricoid should never be cut because stenosis is apt to follow the wearing of a cannula
