Abstract

The oral cavity is irradiated during radiation therapy of radio - sensitive oral malignant tumors. Radiation therapy for malignant lesions of the oral cavity is usually indicated when the lesion is advanced or deeply invasive and cannot be approached surgically. The major salivary glands are at times unavoidably exposed to 20 to 30 Gy during radiotherapy for cancer in oral cavity or oropharynx. The parenchymal component of the salivary glands is radiosensitive. A marked and progressive loss of salivary secretion is usually seen in the first few weeks after initiation of radiotherapy. Aim: Aim was to evaluate changes in parotid and submandibular salivary glands after radiotherapy for head and neck malignancies using ultrasonography Methods: Ultrasonographic evaluation was performed extra orally for bilateral parotid and submandibular salivary glands before radiotherapy and after completion of radiotherapy. Discussion: On ultrasonographic examination we observed decrease in size of salivary glands following radiotherapy. There was decrease in length, width and depth. This decrease in size of salivary glands can be related to chronic inflammation which sets in the glands after exposure to radiation and which leads to subsequent fibrous changes in glands.
