Specifications about the size and stiffness of healthy salivary glands with ultrasound (US) are not available for Asian people. Using a Toshiba Apolio 500 US platform, we determined the size (including anterior-posterior median length, median paramandibular depth dimension, and cranio-caudal height) and hardness of 100 healthy submandibular and parotid glands in volunteers without a history of disease affecting the salivary glands or post-radiation, and compared the dimensions to those of 36 parotid glands and 37 submandibular glands in post-irradiated patients. The dimensions of the parotid and submandibular glands were significantly correlated with body weight. However, the dimension of the parotid glands was not significantly correlated with that of patients with prior radiation; the shear wave velocity (SWV) significantly increased (1.99 m/s versus 2.43 m/s, p-value < 0.01). The dimension of the submandibular glands was significantly correlated with prior radiation, where the SWV also significantly increased (2.32 m/s versus 2.50 m/s, p-values < 0.01). We find that US is a useful tool for assessment of the reference dimensions and hardness of major salivary glands that may be altered by irradiation.

“…Thus, we ultrasonographically evaluated the submandibular glands of patients in terms of echogenicity, echotexture, margin, and dimensional (anteroposterior, superoinferior, mediolateral length, and volume) changes before RT and at the second and sixth months after RT onset. Examination of the submandibular gland with the help of USG is more straightforward because of its anatomical position and size (9) .…”

Ultrasonographic changes of submandibular glands in irradiated patients for head and neck cancers

Ultrasonographic changes of submandibular glands in irradiated patients for head and neck cancers INTRODUCTIONRadiotherapy (RT) is an integral tool in the management of head and neck cancers (1) . Nevertheless, despite the advancement in technology and clinical knowledge, the use of RT for head and neck malignancies can cause major salivary gland (SG) damages because SG parenchyma is very sensitive to radiation, particularly the parotid gland (2) . Changes in the SGs depend on the volume and radiation dosage of the gland in the radiation field, but the mechanisms of these changes are unclear (2,3) .SG damage after RT includes lymphocytic infiltration, degeneration, necrosis, acinar cell loss, atrophy, fibrosis, and duct dilatation (4) . Moreover, reductions in the permeability and blood flow may be present (5) . There have been reports in the literature to accurately assess the effects of head and neck RT on SGs. For this purpose, there are various techniques such as survey, histological evaluation, sialometry,
