Facial nerve palsy caused by parotid gland abscess

Abstract

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