Children with facial paralysis do not necessarily have sequelae. If the rehabilitation is early and the extent of the facial paralysis is small, there may be no sequelae, while on the contrary, there is a high probability of having sequelae. If a child’s facial paralysis is detected in time, the extent of the facial paralysis is small, and rehabilitation is started in time, there is a high probability that there will be no after-effects. If the lesion is small in size but is detected late, there is a high probability of sequelae. If the lesion is extensive, even if rehabilitation is started in time, there is a high probability that there will be after-effects, such as affecting chewing function or even speech function. When children with facial paralysis are detected, it is important to consult a hospital in a timely manner, and under the guidance of a professional rehabilitation technician, treatment can be carried out, for example, through electrical stimulation, acupuncture, massage and other methods to promote recovery, and also through the practice of blowing air and other exercises.
