声门下溃疡

声门下溃疡

喉声带下方可见大溃疡。这样的声门下溃疡是可由长期的气管内插管造成的,往往见于插管过紧。可以通过机械压迫引起。事实上,我们所说的压疮或褥疮形成于骨较突出的皮肤部位,常见于长期卧床病人。

Below the vocal cords in this larynx are large ulcerations. Such subglottic ulcers are produced with prolonged endotracheal intubation in which the cuff of the endotracheal tube fits too tight. Thus, ulcerations can be produce by mechanical forces. In fact, so-called "pressure ulcers" or "decubitus ulcers" can form on skin over bony prominences in persons who are bedridden for an extended time.
