Decompression for Bell's palsy: why I don't do it

All decompression surgery is based on the lack of understanding that Bell's palsy is a viral demyelinating disease that is longitudinal--not perpendicular--to the facial canal and that surgery cannot possibly help a viral disease. These findings exclude the etiologic possibility of an "ischemic paralysis" and are in accord with our logically derived belief that treatment directed to relieve neural entrapment is a wasted effort.
