Vocal Rehabilitation of Paralytic Dysphonia: IX. Technique of Intracordal Injection

The Problem Previous papers 1-3 have reported on the feasibility of restoring the voice in patients suffering from paralytic dysphonia through injecting innocuous substances into the paralyzed vocal cord by means of the technique originally developed by Brunings. 12 Interpretation, diagnosis, and functional evaluation of laryngeal paralysis have been discussed in order to define which conditions are suitable for this procedure. 4-11 In the meantime, other authors have confirmed our experiences and suggested that further studies should be undertaken. 14-16,18 The principle of restoring the voice through narrowing a deficient glottis has been corroborated also by J. G. Waltner, 20 who implanted a cartilaginous graft lateral to the cicatricial cord with good functional results. It seems to be the consensus of these opinions that intracordal injection is a suitable method for vocal rehabilitation in various conditions when the vocal disability is due to insufficient closure of the vocal cords during
