Vocal cord paralysis is mainly caused by laryngeal motor nerve paralysis, and any damage to the laryngeal motor nerve conduction pathway may lead to its occurrence. Whether or not it can be cured is closely related to the cause and severity of the disease. In mild cases, after active treatment of the primary disease, the general function of phonation and respiratory function can be improved, and the disease can be cured. If the symptoms are severe, it is more difficult to cure. The general treatment principle and purpose of this disease is to improve or restore voice function, relieve dyspnea and prevent complications by treating the cause of the disease. 1. Etiological treatment: On the premise of identifying the cause of vocal fold paralysis, give appropriate treatment measures and actively relieve the cause. Systemic or local neurotrophic drugs such as vitamin B₁₂, furothiamine, etc., drugs to improve microcirculation, and hormone therapy when necessary may have some effect on the recovery of nerve function. 2. Speech correction: It is applicable to patients with central lesions, and through certain speech correction methods, the voice quality of patients can be improved to a certain extent. For some peripheral unilateral vocal cord paralysis, there is also a certain effect, even for the final need to accept the surgical intervention of patients, speech therapy is also an effective means of waiting stage, conducive to the recovery of patients. 3. Surgical treatment: ① unilateral vocal cord paralysis: for clear laryngeal recurrent nerve injury, after causative treatment, medication and observation can not be recovered, laryngeal recurrent nerve repair surgery is feasible. Bilateral vocal cord paralysis: such as laryngeal or intralaryngeal arytenoid chondroplasty, CO₂ laser arytenoid chondroplasty. The specific efficacy of the situation needs to be systematically examined after medical treatment, and the condition is evaluated by a specialized doctor.
