Tonsil Stones Diagnosis

Diagnosis is usually made upon inspection. Differential diagnosis of tonsilloliths includes foreign body, calcified granuloma, malignancy, an enlarged styloid process or rarely, isolated bone which is usually derived from embryonic rests originating from the branchial arches.

Tonsilloliths are difficult to diagnose in the absence of clear manifestations, and often constitute casual findings of routine radiological studies.

Imaging diagnostic techniques can identify a radiopaque mass that may be mistaken for foreign bodies, displaced teeth or calcified blood vessels. Computed tomography (CT) may reveal nonspecific calcified images in the tonsillar zone. The differential diagnosis must be established with acute and chronic tonsillitis, tonsillar hypertrophy, peritonsillar abscesses, foreign bodies, phlebolites, ectopic bone or cartilage, lymph nodes, granulomatous lesions or calcification of the stylohyoid ligament in the context of Eagle syndrome (elongated styloid process).
