Patient's question:
What is a facial paralysis?Doctor's answer:
Facial paralysis is primarily characterized by symptoms such as crooked mouth corners, drooling, and abnormal facial muscle movement. Facial paralysis is generally classified into two types: central facial paralysis and peripheral facial paralysis. Central facial paralysis is usually caused by intracranial inflammation, such as tumors or cerebral vascular diseases. Peripheral facial paralysis is mainly due to factors like cold exposure or viral infections that lead to facial nerve dysfunction and subsequent facial paralysis. For different types of facial paralysis, the treatment plans vary. In some cases, further imaging tests such as head CT scans and MRI may be necessary for a thorough examination. Surgical intervention may also be required when needed.
