We prefer to use a laryngeal mask airway (LMA) which does not go through the vocal cords and does not irritate the vocal cords or trachea. Occasionally patients have minor irritation of the back of the throat. Obese patients with large hernias may require endotrachael intubation.
These devices are called airways. Their purpose is to allow an anesthesiologist to control you breathing. This is one of the things which makes modern anesthesia very safe.
