Deep lobe parotid abscess with facial nerve palsy: a case report.

Abstract

Acute suppurative sialadenitis mostly occurs in the parotid gland, while parotid abscesses principally arise in the superficial lobe. However, facial nerve palsy, secondary to parotid abscess, is rare. Predisposing factors for the ductally ascending infection are dehydration, xerogenic drugs and salivary gland diseases associated with ductal obstruction or reduced saliva secretion. Obstruction of Stensen's duct and diminished production of saliva are regarded as the promoting factors. Painful swelling of the preauricular region and cheek is the most familiar symptom of acute suppurative parotitis. The most common pathogens associated with acute bacterial infection are Staphylococcus aureus and anaerobes. We report a rare case of deep lobe parotid abscess with facial nerve palsy. Aside from adequate fluid hydration, good oral hygiene and treatment with empiric parenteral antibiotics, surgical treatment with drainage can provide a remedy for this disease.
