Facial paralysis in children is commonly caused by inflammation and trauma. It usually takes 1 month to 1 year to recover, and in severe cases, it may not recover permanently, and there are large individual differences.
1. Inflammation:
(1) Mild peripheral facial paralysis, such as middle ear mastoiditis and facial neuritis (caused by cold, infection, etc.), usually improves in about 2 weeks~4 weeks and recovers in 1~3 months after receiving active treatment; those who have not standardized the treatment may be able to recover in about 6 months.
(2) Central facial paralysis caused by serious diseases such as encephalitis usually takes about 6 months to 1 year to recover, or even longer or permanent in severe cases.
2. Trauma: Injury to the facial nerve or the central system may not be recoverable in most cases and can only be relieved. If the injury is mild and actively treated, it can usually be recovered in about 6 months; if the injury is severe, it may take a long time or even be lifelong.
Therefore, if a child develops facial paralysis, he or she should seek immediate medical attention to further refine the diagnosis and consult a medical professional.
