The ectopic accessory parotid system: A new patient, studied through magnetic resonance imaging.

The ectopic accessory parotid system (EAPS) connotes an extra parotid tissue with its ductal outlet that is morphologically distinct from the main parotid gland and its drainage system. Clinically presenting as a saliva-draining cheek fistula near the oral commissure, this rare congenital anomaly is almost always associated with ipsilateral preauricular appendages and occasional mandibular hypoplasia, and is considered a variant of the oculo-auriculo-vertebral spectrum. This report discusses the embryology, clinical details, and management aspects in a new patient, highlighting the role of magnetic resonance imaging in, for the first time, tracking the ectopic salivary system, and establishing its independent existence.
