A Large Calculus in the Parotid Duct

We report a case of a large calculus in the parotid duct. A 61-year-old man was referred to us with a painless buccal mucosal swelling. Oral examination showed a hemispheric buccal mucosa swelling around the orifice of the parotid duct in the right cheek. The patient denied intermittent swelling and pain of the right parotid gland at mealtime. Salivary secretion was smooth from the orifice and there was no salivary fistula. An oblique radiograph of the right cheek revealed a single, well-defined, homogenous radiopaque mass. Computed tomography scanning showed a high-density mass, round with a 1-cm diameter. The calculus was removed by an oral approach under local anesthesia. The calculus was an irregular globule in shape, 1×1×1 cm in size, and yellowish white in color. Follow-up examination one year later was uneventful.
