Facial Paralysis Following Core Needle Biopsy of a Deep Lobe Parotid Tumor: A Case Report.

OBJECTIVES

: To report a case of total facial paralysis as the result of a core needle biopsy.

METHODS

: Case report and literature review.

RESULTS

: A 70-year-old man was diagnosed with a deep lobe parotid tumor on computed tomography. During a core needle biopsy, he developed complete facial paralysis. The cause was discovered to be a direct stab injury to the main trunk of the facial nerve.

CONCLUSIONS

: When biopsying parotid lesions adjacent to the main trunk of the facial nerve, the use of smaller-gauge needles and additional patient counseling should be considered.
