Since the eye cannot blink or close properly, protecting the eye is the most important goal in the management of facial paralysis. Without proper eye protection, corneal abrasions can occur, leading to infection and eventual blindness. At night it is best to cover the eye with an eyepatch or a moisture chamber. During the day, the eye can be left uncovered, but artificial tears and lubrication ointment should be used often to prevent injury and infection.  Approximately 10% of patients who experience facial paralysis from Bell’s palsy will develop synkinesis, or abnormal, unwanted facial movement. This most often occurs in patients who experience delayed recovery of facial movement over several months, rather than those who recover in a few weeks.
