Abstract
The thyroplasty type I, described by ISSHIKI et al.(1975) and the arytenoid adduction technique, proposed by ISSHIKI et al.(1978) have been employed on patients with imperfect closure of the glottis due to unilateral vocal cord paralysis. The arytenoid adduction technique is specially indicated for a wide, glottal chink and when there is a difference in level of the two cords. Both techniques are rather simple and the improvement of voice is significant. The surgical procedures are described in detail.
