Parotitis in a three-year-old.

Facial swelling cannot routinely be attributed to dento-alveolar infections until a thorough head, neck and oral examination has been completed. Facial swelling from parotitis is not commonly encountered in the pediatric patient. The purpose of this report was to document a case of unilateral parotid gland infection presumably secondary to traumatic obstruction of Stenson's duct. The parotitis resolved following a course of oral penicillin VK and lemon juice to stimulate salivary flow. Several parotid gland disorders which involve facial swelling were discussed.
