Teflon injection for vocal cord paralysis after intracranial operation

Vocal cord paralysis may follow intracranial operation if the vagus nerve is damaged intraoperatively. If the resulting laryngeal incompetence is severe, hoarseness, dysphagia, and aspiration may develop. This is often followed by a pneumonitis requiring chronic gastric tube feeding. Teflon vocal cord injection has been shown to restore the sphincteric action of the larynx and enable patients to phonate and swallow properly again. Nine patients underwent this procedure for chronic aspiration and hoarseness. All had vagus injury attributable to antecedent intracranial operation, and all experienced relief of their symptoms with only minor complications. Teflon vocal cord injection is advocated as a safe, effective means of managing patients with aspiration and dysphagia secondary to vagus nerve injury.
