An update on the use of ultrasound imaging in oral and maxillofacial surgery

Abstract 

Ultrasound is a relatively inexpensive, non-invasive, and readily available technique that is well tolerated by patients. It is particularly useful in the examination of superficial structures where the use of a high frequency linear probe (7.5–12MHz) produces high definition multi-planar images. The spatial resolution achieved is superior to other methods of cross-sectional imaging and, when combined with tissue biopsying techniques such as fine needle aspiration cytology (FNAC) or core biopsy samples, it is rendered a highly specific diagnostic tool. This article provides an overview of the use of ultrasound for common head and neck conditions, including its use in salivary gland disease, and for the assessment of cervical lymphadenopathy.
