Transoral sonographic diagnosis of tonsilloliths: report of 3 cases.

Tonsilloliths are calcified concretions that develop in tonsillar crypts. They are usually asymptomatic; however, they may cause problems such as halitosis, dysphagia, a globus sensation, and otalgia. Tonsilloliths may be diagnosed by a simple inspection or palpation of tonsillar crypts, which can be confirmed by panoramic radiography, computed tomography, or magnetic resonance imaging. We report 3 cases of tonsilloliths diagnosed by transoral sonography that was performed easily and comfortably in an office-based setting.
