The following imaging studies may be considered:

  • Lateral soft tissue neck radiography (to help rule out other causes)

  • Intraoral ultrasonography

  • Computed tomography (CT) of the head and neck with intravenous (IV) contrast (if incision and drainage fails, if the patient cannot open his or her mouth, or if the patient is young and uncooperative)

See Workup for more detail.
