The applicability of ultrasound in the diagnosis of inflammatory and obstructive diseases of the major salivary glands: a scoping review.

Objectives: The purpose of the present scoping review was to determine the contribution of ultrasound images in the diagnosis of inflammatory and obstructive diseases of the major salivary glands (MSGs).

Methods: A search of studies of ultrasonographic assessments of human samples was performed in several electronic databases and grey literature up to July 2021. The extracted data were the examined MSG; the diagnostic value of ultrasound (sensibility, specificity, positive- and negative predictive value, accuracy); features of lesions, including number, echogenicity, echotexture, form, margins, size, posterior acoustic aspect, and location; and related clinical information, such as swelling, palpation, sensible to pain, salivation, lymph nodes, recurrence, duration, and causes.
