- 1氣管切開術（台灣醫院口語常說「氣切」）
A tracheotomy is an operation in which a doctor cuts a small opening in the front of the neck, into the , so that a person can breathe through that hole instead of through the nose and mouth. It is done when the normal way in is blocked or damaged, or when a patient needs a machine to help them breathe for a long time. A tube is usually put into the opening to hold it open, and the person may then speak in a different voice, or need help to speak at all. Later the hole can often be closed again. This is a medical word, and you will meet it in hospitals, medical dramas, and news reports about someone badly . You will also see the very similar word 'tracheostomy'. Doctors sometimes separate them — the cut itself versus the lasting opening — but in ordinary use, including in the news, the two words are used for the same thing, so do not worry if you see both.
組成tracheo-（氣管，來自 trachea）+ -tomy（切開，來自希臘文 τέμνω「切」）。合起來就是「把氣管切開」。-tomy 這個結尾在醫學字裡很常見，看到它就知道跟「開刀切開」有關。
