laryng-, laryngo- +
(Greek > Modern Latin: throat, upper part of the windpipe; the vocal-chord area of the throat; the musculocartilaginous structure below the tongue root and hyoid bone and above the trachea)
Stedman's Medical Dictionary, 28th Edition, cautions users to be aware of the proper pronunciations of laryngo- (luh RING goh) and laryng- (luh RINJ): "Avoid mispronouncing this combining form lar-in' jo" or (lar IN joh).
Here is a special article about the Neck and Throat.
The operation is indicated for certain malignant tumors of the cervical esophagus and hypopharynx.
In either operation, the surgeon performs a tracheostomy, creating an opening called a stoma in the front of the neck which may be temporary or permanent.
Air enters and leaves the trachea and lungs through this opening. A tracheostomy tube, also called a trache tube, keeps the new airway open.
A partial laryngectomy preserves the voice. The surgeon removes only part of the voice box, just one vocal cord, part of a cord, or just the epiglottis, and the stoma is temporary.
After a brief recovery period, the trache tube is removed, and the stoma closes up. The patient can then breathe and talk in the usual way. In some cases, however, the voice may be hoarse or weak.
In a total laryngectomy, the whole voice box is removed, and the stoma is permanent. The patient, called a laryngectomee, breathes through the stoma. A laryngectomee must learn to talk in a new way.
