Abstract
The result of transcutaneous intrafold injection and its influencing factors were studied for fifty five procedures in fifty two patients with unilateral recurrent nerve paralysis. Maximum phonation time, mean air flow rate and amplitude perturbation quotient of the voice were normalized or improved after the procedures more than 85%. In general assessment with functional and acoustic examinations, 76% of the procedures showed significant improvement. The paralysis after the thoracic surgery, right vocal fold paralysis and the paralysis complicated with sulcus vocalic tended to have insufficient improvement after injection. The most significant correlation to the result was shown in the degree of vocal fold augmentation immediately after injection. It was depend on the surgeon's technique and the patient's problems such as an anatomical abnormality of the larynx and an insufficient inhibition of the gag reflex.
