1 Nasointestinal tube; Glottis exposing difficulty; Intubation, intratracheal.

2 Glottis epiglottis plays the role of the protective cover.

3 Acoustic Source at the Glottis.

4 Direct laryngoscopy revealed narrowing of the glottis with diffuse ulcerative necrotic tissue.

5 Methods: Refering to the method of electronic glottis graph and mathematics analysis, using 16 characteristic dots, an analysis method and quantitative analysis formula are established.

6 Conclusion: Changeable head position can improve the glottis visualization under direct laryngoscopy in a great degree.

7 The anterior two third of glottis (phonatory portion), mucosa over the posterior commissure and the arytenoids muscle all remain intact.

8 And open the throat, glottis gas block is an indispensable condition.

9 Because of inertia, though, the air column continues to move up, leaving a partial vacuum in and above the glottis that acts to slam the folds more strongly together.

10 Objective To determine the clinical characteristic, treatment and prognosis for poorly differentiated carcinomas of the glottis.

11 An oxygen -supply pipe and suction tube are settled on the bottom and side of tongue-spatula to provide oxygen and absorb phlegm simultaneously on exposure of glottis.

12 Air that is expelled from the lungs passes through the glottis.

13 Conclusion:For selected cases, using omohyoid myofascial flap to repair the partial laryngeal defect and reconstruct glottis is available and practicable.

14 HintJust put your hand on your throat, you can feel the vibration of the glottis.

15 For selected cases, using omohyoid myofascial flap to repair the partial laryngeal defect and reconstruct glottis is available and practicable.
