3. Brain diseases: for example, intracranial hemorrhage or intracranial tumors and other intracranial occupying lesions compressing the facial nerve can also appear this phenomenon.
Parents are advised to take their children to regular hospitals in time to clarify the specific causes and then deal with them under the guidance of doctors.
