Facial nerve palsy caused by parotid gland abscess

Abstract

Objectives: We present the first report of methicillin-resistant Staphylococcus aureus and Propionibacterium acnes parotid abscesses complicated by facial nerve palsy. Facial nerve palsy secondary to parotid gland abscess is rare, with only eight previously reported cases.

Method: Case reports and literature review concerning parotid abscess and facial nerve palsy presentation and management.

Case reports: Within two months, two female patients presented with parotid gland abscess complicated by unilateral facial paralysis. Both were treated with intravenous antibiotics and surgery. In the first case, methicillin-resistant Staphylococcus aureus was cultivated, in the other, Propionibacterium acnes was found. In the first case, facial nerve function did not recover.

Conclusion: Parotid gland abscess can lead to facial paralysis. Both methicillin-resistant Staphylococcus aureus and Propionibacterium acnes may be involved. Ultrasonography or computed tomography is recommended to exclude a parotid abscess in patients presenting with suppurative parotitis.
