Summary:Unilateral recurrent laryngeal nerve paralysis causes the vocal cord to atrophy, leading to glottic incompetence. The voice is characterized by hoarseness, breathlessness, rapid air escape, ineffective cough and aspiration. Traditional treatments of unilateral vocal cord paralysis include intracordal injection, laryngeal framework surgery, and laryngeal reinnervation for medialization of the vocal cord. In this paper we report on a new technique of transcutaneous intracordal silicon injection in which the injection is made through the thyroid lamina under local anesthesia monitoring fiberscopy. We performed this procedure on 30 patients with unilateral vocal cord paralysis and later evaluated their post-operative voice. The silicon injection resulted in improvement of vocal quality, favorable clearance of sputum, and aspiration control. We found that, since it can be performed under local anesthesia without hospitalization, transcutaneous intracordal silicon injection should be performed as a therapy for treating unilateral vocal cord paralysis.
