Unfortunately there is no treatment for Bell's palsy. It is important to keep in mind that the disorder almost always eventually goes away on its own without any sort of intervention.
Most people recover within a few weeks, though some cases persist for several months.
Only 1 in 10 patients never experience a complete disappearance of symptoms. The most important part of treatment is to keep the eyes healthy and moist. One of the purposes of blinking and closing the eyes is to keep the eyes wet. If a person can't close their eyes, because the muscles that control the eyelids are paralyzed, it is important to keep the eyes moist and prevent itching and discomfort. Eyedrops are prescribed for the day, an eye ointment for night, and patients should sleep with a humidifier or moisture chamber at night.
