Laryngectomy

n. surgical removal of the larynx (Medicine)

Laryngectomy is the surgical removal of the larynx and separation of the airway from the mouth, nose, and esophagus. The laryngectomee breathes through an opening in the neck, a stoma. It is done in cases of laryngeal cancer. However, many laryngeal cancer cases are now treated only with radiation and chemotherapy or other laser procedures, and laryngectomy is performed when those treatments fail to conserve the larynx.
