Question
How long after blowing cold wind does facial paralysis occur?
Answer
For a long time, it has been believed that facial paralysis is associated with neurotropic virus infections. Most cases occur after a cold or upper respiratory infection, and some patients may be caused by herpes zoster virus infection. As shown in the image, patients with facial paralysis may have drooping corners of the mouth, especially when speaking, whistling, or laughing, when the symptoms are more pronounced. The symptoms vary depending on the location of the facial nerve injury. For example, if the injury involves the facial nerve, there may be a sensory impairment of about two-thirds of the tongue’s anterior part. If the injury involves the facial nerve, tinnitus may occur. In addition to facial paralysis, tinnitus, and sensory impairment, there may be herpes in the ear canal in cases of neuritis. It is indeed possible to develop facial paralysis from frequently blowing cold wind.
