Radiation‐induced volume changes in parotid and submandibular glands in patients with head and neck cancer receiving postoperative radiotherapy: A longitudinal study

Abstract

The parotid and submandibular glands shrunk during RT, but the parotid glands shrunk more than the submandibular glands. These gland volume reductions correlated significantly with the mean dose to the irradiated glands; the spared glands showed few changes.
