Loss of the larynx due to disease or injury will result in numerous and significant changes that cross anatomical, physiological, psychological, social, psychosocial, and communication domains. Surgical removal of the larynx, or total laryngectomy, involves resectioning the entire framework of the larynx. Although total laryngectomy may occur in some instances due to traumatic injury, the majority of cases worldwide are the result of cancer. Approximately 75% of all laryngeal tumors arise from squamous epithelial tissue of the true vocal fold (Bailey, 1985). In some instances, and because of the location of many of these lesions, less aggressive approaches to medical intervention may be pursued. This may include radiation therapy or partial surgical resection, which seeks to conserve portions of the larynx, or the use of combined chemoradiation protocols (Hillman et al., 1998; Orlikoff et al., 1999). However, when malignant lesions are sufficiently large or when the location of the tumor threatens the lymphatic compartment of the larynx, total laryngectomy is often indicated for reasons of oncological safety (Doyle, 1994).
