Note mouth-gag provided with ether vapor tubes. 92 SURGICAL TREA TMENT grown downward into the sphenoid so far as to be inaccessible from such circumstances the surgeon may proceed to make an incisionalong the inner margin of the orbit, remove the inner wall of the orbit, gainaccess to the posterior nares, and complete the operation by the intranasalroute. The bucconasal route is practically the same as the low nasal gives more room than the unilateral operations, and does not require therhinologists skill. Intratracheal etherization is most effective in these opera-tions. A transverse incision is made in the mucous membrane at the anglewhere the posterior lining of the upper lip is reflected upon the alveolar process.

The mucous membrane is separated upward, and theseptum of the nose exposed without opening through the mucous membrane ofthe nasal cavities (Fig. 752). The mucous membrane is separated fromthe septum and retracted laterally. The cartilaginous septum is cutthrough obliquely at the level of the anterior limit of the upper jaw.
