Abstract
The main purpose of intracordal injection is to improve glottal closure during phonation. Endolaryngeal microsurgical technique under general anesthesia and/or peroral approach with indirect laryngoscopy have been reported in the majority of the studies dealing with this procedure.
In this paper, a new percutaneous intracordal injection technique is introduced for improvement of the glottal closure during phonation in the unilateral recurrent laryngeal nerve paralysis.
Phycon 6500 injection with Katsunuma's needle (bone marrow needle) was performed in six patients who complained of hoarseness. The voice improved satisfactorily on a postoperative phonatory function test in most of the cases.
