Application progress of swallowing function training in dysphagia of patients with head and neck cancers undergoing radiotherapy

Dysphagia is one of the common adverse reactions after radiotherapy for head and neck cancers (HNC). As time goes on, the disease will worsen, leading to malnutrition, aspiration pneumonia and even death. Although swallowing function training has certain therapeutic effects on HNC patients, the training methods have not yet been unified. The author reviews the mechanism, influencing factors and evaluation methods of dysphagia in HNC patients after radiotherapy, in order to provide ideas for the prevention and treatment of dysphagia in HNC patients after radiotherapy.
