How long can a face paralysis eye close?

Patient's question:

Recently, I found that the symptoms of facial paralysis have reappeared. Hello, how long can the eyes with facial paralysis close?

Doctor's answer:

The treatment of acute facial paralysis primarily focuses on preventing the recurrence of exposure keratitis. For example, applying ointment to the affected eye during nighttime sleep or covering it with clean gauze to prevent bacterial or viral keratitis. Most patients can achieve significant recovery within about 2 weeks of standardized and systematic treatment. However, some patients may have a longer recovery period, potentially requiring 3 months or even longer. In some cases, permanent facial asymmetry or incomplete eyelid closure may still remain.
