Additional Causes & Treatments
Below are all examples of additional causes of Facial Paralysis.
Physical trauma, especially fractures of the temporal bone, may also cause acute facial nerve paralysis. Understandably, the likelihood of facial paralysis after trauma depends on the location of the trauma. Most commonly, facial paralysis follows temporal bone fractures, though the likelihood depends on the type of fracture.
Reactivation of herpes zoster virus, as well as being associated with Bell’s palsy, may also be a direct cause of facial nerve palsy.
Otitis media is an infection in the middle ear, which can spread to the facial nerve and inflame it, causing compression of the nerve.
Lyme disease, caused by chronic Borrelia burgdorferi infection, is a common cause of facial nerve paralysis in endemic areas.
Central facial palsy can be caused by a lacunar infarct affecting fibers in the internal capsule going to the nucleus. The facial nucleus itself can be affected by infarcts of the pontine arteries.
