About Bells Palsy
palsy is a common condition in which the facial nerve becomes
weak. The facial nerve allows us to move the muscles of
our face such as when we smile, frown, cry, or laugh. Thus,
patients with bells palsy have facial paralysis and appear
to have droopy eyebrows, sagging cheeks and mouth and appear
to have had a stroke.
The facial nerve travels a complicated course from the brain, through the inner
ear, and into the face. Thus, a number of different medical conditions can
affect the facial nerve. One of these conditions is bells palsy. While the
exact cause of bells palsy is not known, it is likely a result of swelling
and inflammation of the nerve caused by a viral infection. However, other conditions
can also cause facial paralysis, from relatively minor problems such as an
ear infection to more serious problems such as a stroke and a tumor.
