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.
