Course.—The tendency of the palsy to improve in peripheral facialparalysis is marked, excepting in destructive lesions of the that improve get practically well in from three vreeks to eighteenmonths, depending upon the amount of injury done the nerve and theduration of pressure Avithin the facial canal.

DISEASES OF THE FACIAL NERVE. 127 treatment in those cases that depend upon so-called rheumatic condi-tions, though improvement may without doubt be accelerated by propermanagement. The early loss of faradic stimulability of the musclesgradually passes away, but voluntary motion returns before the faradiccurrent regains its control. Very frequently the paralyzed muscles willtwitch or even act in vigorous spasm as regeneration in the nerve re-stores its irritability. Those cases which last a month or two, or more,usually leave traces for the rest of life. They may be so slight as torequire careful scrutiny, or marked weakness may persist. Very excep-tionally the palsy is permanent.
