Crooked mouth due to facial neuritis usually heals in about 1 to 2 months. If the facial neuritis is more serious and is not treated or controlled in time, it may take a longer recovery time, depending on the individual. Facial neuritis is an inflammatory lesion of the facial nerve, which belongs to the category of facial paralysis, and can lead to symptoms such as crooked mouth and eyes, leakage of wind in speech, and inability to close the eyes. Under normal circumstances, as long as you go to the Neurology Department of regular hospitals for standardized treatment in a timely manner, under the guidance of a professional doctor to take nerve-nourishing drugs such as methylcobalamin, vitamin B1, as well as antiviral drugs, most patients can be cured in about 1 to 2 months. If facial neuritis is not treated in time at the early stage of the disease or if the treatment is not standardized, resulting in the condition becoming more serious, it often requires a longer recovery time, which may be about 2~3 months, or half a year, or even longer. Once the symptoms of facial neuritis with a crooked mouth appear, it is recommended to go to a regular hospital as soon as possible for consultation and treatment, which will help alleviate the condition and improve the symptoms.
