Facial palsy results in droopy lower lid and eye exposure. In severe cases this could result in blindness due to eye infection in relation to long standing exposure.
Conservative measures are with heavy lubrication with artificial tears and lubricating ointment, until the facial palsy is healed.
Fillers could be an alternative to surgery to help with blinking and avoiding dry eyes. Otherwise surgery is needed to cover the eyeball, and this is accomplished by tightening the lower eyelid, to keep the lower lid in higher position and to support the eyeball.
The surgery could be done under general or local anaesthesia, depending on the patient preference.
