Otherinstruments needed are a narrow scalpel, four small retractors, mouse-toothforceps, hemostats, needles, thread, and the special instruments to meet thespecial conditions present. Either general or local anesthesia may be used; and in desperate, cyanoticcases, no anesthetic is required. The patient should be in the lowered-headposition with the head extended by dropping the head-rest part of the table(Fig. 508) or with a sand pillow behind the shoulders, to bring into strongrelief the structures in the front of the neck. If there is great engorgement ofthe veins of the neck the sand pillow without the lowered-head position.

If the cricoidcartilage is divided in the operation of tracheotomy, it is a the operation is done above the isthmus of the thyroid gland it is calledhigh tracheotomy. This is the easiest and mostcommonly performed operation. The promi-nent thyroid cartilage of the larynx is the land-mark. Below it the cricoid cartilage can befelt. An incision in the median line is madethrough the skin from above the level of thecricoid downward for 4 or 5 cm. (1^ or 2inches). The veins lying in the superficialfasc
