Examination of parotid gland in diabetics with ultrasound elastography and microvascular imaging.

BACKGROUND

Diabetes mellitus is a prevalent metabolic disorder that can result in the non-enflamatuar enlargement of the parotid gland. It is recognised as a condition that can impair microvascular perfusion.

MATERIAL AND METHODS

The parotid glands of 38 individuals with diabetes and 38 healthy controls were examined bilaterally using ultrasound to assess parameters of volume, stiffness and microvascularity.

RESULTS

A statistically significant increase in parotid gland volume and a statistically significant decrease in microvascularity were observed in diabetic patients. Furthermore, a statistically significant increase in parotid gland volume was noted in diabetic individuals who were using antidiabetic drugs in comparison to non-users. A significant negative correlation was identified between the duration of exposure to diabetes and microvascularity.

CONCLUSIONS

Ultrasonographic imaging can be used to assess the dimensions and microvascularity of the parotid gland.
