Vocal cord paralysis causing hoarseness in the throat has a complex etiology, and any damage to the laryngeal motor nerve conduction pathway may lead to its occurrence. The etiology is mainly categorized into central damage and peripheral damage. The general principle and purpose of treatment is to improve or restore voice function, relieve dyspnea and prevent complications by treating the cause of the disease on the basis of clarifying the etiology. 1. Etiological treatment: On the premise of defining the cause of laryngeal 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 therapy: Speech therapy is applicable to patients with central lesions. Through certain speech therapy methods, the voice quality of patients can be improved to a certain extent. For some peripheral unilateral laryngeal paralysis, there is also a certain effect, even for the final need to accept surgical intervention, speech therapy is also an effective means of waiting for the stage, conducive to the recovery of patients. 3. Surgical treatment: for unilateral vocal cord paralysis, anastomosis of the main branch of the cervical collaterals or the anterior root of the cervical collaterals is the first choice, and anastomosis of the cervical collaterals and direct anastomosis of the laryngeal reentrant nerve can be used, as well as anastomosis of the laryngeal reentrant nerve end to end. For bilateral vocal cord paralysis, laryngeal recurrent nerve adduction and abduction combined nerve repair can be used to restore the physiological inspiratory abduction and phonatory adduction of the vocal cord. If vocal cord paralysis causes hoarseness, it is recommended to go to a regular hospital as soon as possible for a systematic examination, and follow the doctor’s instructions to standardize the use of medication and treatment.
