Swallowing Structure Related to Acute Dysphagia in Head and Neck Cancer

Abstract

Progress in head and neck cancer (HNC) therapies has improved tumor response, loco-regional control, and survival. However, treatment intensification also increases early and late toxicities. Dysphagia is an underestimated symptom in HNC patients. Impairment of swallowing process could cause malnutrition, dehydration, aspiration, and pneumonia. Unidentified dysphagia caused significant morbidity, increased mortality, and decreased the quality of life.
