Patients who have cancers of the oral cavity, pharynx, or larynx may be treated with surgery, radiotherapy, chemotherapy, or a combination of these modalities. Each treatment type may have a negative impact on posttreatment swallowing function; these effects are presented in this article. A number of rehabilitative procedures are available to the clinician to reduce or eliminate swallowing disorders in patients treated for cancer of the head and neck. The various procedures—including postures, maneuvers, modifications to bolus volume and viscosity, range-of-motion exercises, and strengthening exercises—and their efficacy in patients treated for head and neck cancer are discussed.
