What is a Tracheotomy?
An operation which allows air to reach the lungs without first passing through the upper airways, that is the nose, mouth, pharynx or larynx. A vertical cut is made in the front of the neck below the Adam's apple, through which a small tube, or air pipe, is passed. The operation is performed, sometimes in an emergency, if the patient's upper airways are obstructed by severe facial injuries, by a foreign body in the pharynx, by paralysis of the vocal chords, by cancer or the larynx or by a swelling of the throat. A tracheotomy may also be performed if the patient has difficulty in breathing after a head injury, a chest injury, a drug overdose or a stroke. Once he has recovered the tube is removed, the wound is closed and the patient reverts to normal breathing.
