Idiopathic facial paralysis refers to idiopathic facial nerve palsy, and 70% of patients with idiopathic facial nerve palsy can recover spontaneously after six months of onset. Patients with idiopathic facial nerve palsy may have a bulging of the cheeks, closed eyes, frowning, weakness of the closed lips, showing of the teeth, tilting of the corners of the mouth to the contralateral side, and may be accompanied by pain behind the ear on the same side or pain in the mastoid process. Most patients with idiopathic facial nerve palsy have a favorable prognosis and begin to recover 2 to 4 weeks after the onset of the disease, with full recovery after 3 to 4 months. Even if patients with facial nerve palsy do not receive treatment, 70% of them still recover completely six months after onset. Only some patients may have residual facial muscle association band movement, facial muscle weakness, facial muscle spasm, and crocodile tears after recovery. Currently, glucocorticosteroids such as prednisone, antiviral drugs such as acyclovir, and B vitamins are commonly used in clinical practice to provide medication, and massage and physical therapy are also effective. It is recommended that patients with related symptoms go to regular hospitals for timely consultation, follow the doctor’s instructions for symptomatic treatment, and do not rely too much on self-healing.
