Head and neck ultrasound: why now?

This article provides an overview of ultrasound and the techniques for its use by otolaryngologists in diagnosing and treating neck masses and lesions. Head and neck ultrasound is extremely useful in diagnosing neck masses and lesions and in facilitating many procedures that are commonly performed on the head and neck. Although in the past these studies were generally performed by radiologists, clinicians are now able to perform high-quality ultrasound studies and ultrasound-guided procedures in the head and neck. Given the advanced knowledge of head and neck anatomy and disease processes that otolaryngologists possess, head and neck ultrasound offers a logical and valuable extension of the physical examination. Recent improvements in ultrasound resolution, portability, and affordability have provided an excellent impetus for otolaryngologists to incorporate ultrasound into their office and operative practices.
