Cheevermade an incision from near the inner canthus on each side of the nose,downward along the natural furrow, arouiul the ahv to the median line of thelip, which he divided. These flaps were reflected upward and outward hs faras the malar prominences, and the body of each superior maxilla was sawedfrom behind forward to the middle meatus of the nose; the septum and vomerw^ere cut with scissors; the jaws were then depressed and the tumor removed,after which the bones were replaced and wired in position. The loss ofblood was not great, but the patient died on the fifth day from exhaustion. The General Comments.—The excision of the entire upper jaw may bepracticed for the removal of neoplasms, or only the portion below the line. Fi(i. 759.—Kochers iiutliod. 58S OPERATIVE SURGERY. of the orbital floor may be removed. The superior maxilla can be raisedajid turned outward on a hinge formed b} the zygomatic process of themalar bone and the contiguous soft parts by dividing the bone in the line ofFerguson-Webbers incision (Fig. 333, b, b), the upper portion of which, forthis purpose, should be extended to the malar bone. The maxillae are sep-arated by sawing through the hard palate and alveolar process, and the nasalbone is disconnected from the superior maxilla by severing its connectionswith bone forceps. The osteocutaneous flap can then be raised and swungoutward. If necessary, the soft palate may be divided. After the removalof the growth, the parts, including the soft palate, are adjusted and joinedby sutures. With the view of avoiding as far as possible the division of the terminalfilaments of the superior dental nerve, and obviating the loss of functionincident thereto, Langenbeck reco
