Reversible facial nerve palsy due to parotid abscess.

Introduction: A facial nerve palsy combined with parotid enlargement usually suggests malignancy. It is highly unusual for facial nerve palsy to result from a benign situation such as inflammation or infection of the gland.

Presentation Of Case: We present a rare case of facial nerve palsy due to parotid abscess.

Discussion: A literature search retrieved thirty-two cases of facial nerve palsy due to benign parotid lesions since 1969. Only nine reported the presence of a parotid abscess. The etiology of paralysis remains unknown although certain factors such as the virulence of the offending organisms or perineuritis, have been suggested. Best diagnostic evaluation and management are discussed.

Conclusion: In clinical practice, exclusion of malignancy is mandatory, as it represents the most common cause of facial palsy in the presence of a parotid lump.
