Unilateral poor closure of the vocal folds may be caused by chronic laryngitis, neoplastic organisms of the vocal folds, neck tumors, etc., which need to be given medication and surgical treatment according to their etiology. 1. Chronic laryngitis: chronic laryngitis leads to congestion, edema and poor closure of the vocal folds, which requires strict vocal abstinence. If the bacterial infection is acute and inflamed, antibiotics such as cefprozil tablets, cefixime dispersible tablets and roxithromycin capsules can be given to fight infection. 2. Vocal cord neoplasm: If the unilateral vocal cord is not closed properly due to vocal cord nodule or vocal cord polyp, endoscopic surgery can be considered. 3. Neck tumor: If the laryngeal recurrent nerve is paralyzed due to compression by neck tumor, causing unilateral vocal fold inappropriateness, surgical removal of the tumor can be considered. It is recommended to consult a doctor to clarify the cause of the disease and treat the cause of the disease.
