The authors evaluate the results obtained in a group of implemented medializations of the vocal cord. Thyroplasty type 1 was performed 14 times, injection of teflon paste 7 times and injection of Gelaspon once. Eleven operations were made on account of atrophy of the vocal cord, 12 operations on account of unilateral paresis of the vocal cord, in one case a post-traumatic condition of the larynx was involved. The maximal phonation time after surgery increased in patients with atrophy by 3 seconds, in patients with pareses of the vocal cord by 9 seconds. The range of the voice was improved on average by by 6 tones in operated unilateral pareses of the vocal cord and by two tones in atrophy of the vocal cord. The intensity range of the voice improved on average in operated atrophies of the vocal cords by 8 dB, in operated pareses of the vocal cords by 12 dB. According to subjective data reported by the patients the voice improved in 13 instances and became normal or almost normal in 11 instances. Preoperative vocal fatigue receded in 16 instances and improved in eight. Difficulties with food aspiration were reported in seven cases, in five they receded completely, in two they improved.
