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.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
