Abstract

This chapter discusses dysfunction in swallowing, where swallowing requires a complex and precisely coordinated interaction of oropharyngeal and laryngeal structures. Tumors of the tongue and other structures of the oral cavity affect speech production while tumors of the larynx impact voice production. Rehabilitation and restoration of swallowing function following ablative therapy for tumors of the aerodigestive tract are essential for maintaining an acceptable quality of life after treatment. Swallowing depends on a series of biochemical events between the oropharyngeal and laryngeal anatomy, motor function and physiology. Any treatment that impedes laryngeal excursion will result in swallowing problems. Multidisciplinary management is essential for patients with head and neck cancer because the disease and its treatment affect the complex interactions between respiration, swallowing, voice and speech production. The degree of swallowing impairment often depends on the quality of the reconstruction rather than the extent of the tongue resection.
