Prognosis of facial neuritis: The factors that affect the prognosis of facial neuritis depend mainly on the severity of the disease and whether the treatment is timely and appropriate. The prognosis of facial palsy can be determined using electromyography with electrical excitability tests. This can be done two weeks after the onset of the disease. The prognosis is generally good, with recovery usually starting 1 to 2 weeks after the onset of the disease and healing (without nerve degeneration) within 2 to 3 months, with no sequelae. In cases of partial nerve degeneration, recovery takes 3-6 months, and in more severe cases, recovery is slow or non-recovery. Those who have not recovered for more than 6 months have a poor prognosis, and some may have facial muscle spasm or facial muscle twitching. The former shows deepening of the nasolabial fold on the diseased side, the corners of the mouth are pulled toward the diseased side, the eye fissure becomes smaller, and the healthy side is easily mistaken for the diseased side (inversion phenomenon); the latter shows involuntary twitching of the facial muscles on the diseased side, and the symptoms are more obvious when nervous, which can affect normal work in severe cases. A small number of patients can also appear “crocodile tears”, that is, when eating, the diseased side of the eye tears. The patient should take active health care measures to cooperate with the treatment, such as keeping the face warm, wearing a scarf or mask when going out, avoiding wind blowing directly on the face, and eating less or no frozen drinks or food. The important point is to drink enough water every day.
