Ultrasound in maxillofacial imaging: A review

The story of the application of ultrasound (US) in imaging goes back a long way in history. It has been deemed useful in various situations and has evolved over time to a more sophisticated and precise modality. Some of the advances are in the form of newer and more useful equipment increasing its pertinence in dentistry and medicine. Currently, it is being used in various head and neck pathologies owing to its non-invasive nature and has gained wider acceptance in maxillofacial imaging. In this paper we will take a relook of US in areas such as its history, basic principles, advances in the equipment and wide array of applications in head and neck pathologies and also weigh its merits and demerits in specific areas.
