Vocal cord paralysis on one side can be treated to improve function and symptoms, and the symptoms of vocal cord paralysis can be improved by compensating for the muscle contraction on the opposite side to compensate for the symptoms caused by vocal cord dysfunction on one side, so vocal cord paralysis on one side can be cured through active treatment, nerve nutrition and rehabilitation. If bilateral vocal cord paralysis occurs, it is more problematic, because bilateral vocal cord paralysis will be accompanied by swallowing difficulties, choking and coughing. In this case, it is necessary to actively treat the primary disease to avoid severe bilateral vocal cord paralysis, which can have serious consequences. One side of the vocal cord paralysis can be cured by treatment, which may not be as good as the original, but can basically replace the original dysfunction.
