Applications of ultrasonography in oral and maxillofacial surgery: a review of the literature

Abstract

Ultrasonography is a diagnostic medical procedure that employs high frequency sound waves to produce dynamic visual images of organs, tissues, or blood flow inside the body. Until recently it found little application in oral and maxillofacial surgery despite the fact that it is readily available, non-invasive, relatively inexpensive, painless and can be repeated as often as possible without risk to the patient. This article reviews the available literature on the ultrasonographic examination of the head and neck with particular reference to oral and maxillofacial surgery and evaluates the applications of this imaging modality in modern clinical practice. It further highlights the need for clinicians to explore and fully appreciate the diagnostic value of this highly under-utilised imaging modality
