Facial Paralysis from Facial Nerve Tumors

A facial paralysis that begins insidiously and progresses in severity is characteristic of a tumor arising from the facial nerve or, more commonly, a tumor that arises from adjacent structures and secondarily invades the facial nerve.

Complications for Facial Paralysis from Facial Nerve Tumors

Left untreated, malignant facial nerve tumors can follow along adjacent nerves and enter the brain.  They can also spread via metastases to the lungs.  Benign facial nerve tumors will not spread to other areas of the body, but they can cause facial paralysis that will persist until the tumor is removed.
