[Results of an endolaryngeal method of vertico-lateral transposition of the vocal cord for bilateral abductor paralysis (author's transl)].

12 years' experience with a modification of Thornell's technique, modified by Langnickel-Koburg. We operated 146 patients with bilateral vocal cord paralysis during the past 12 years (1969-1981). Objective confirmation of the improved glottic function was obtained by spirometry, body plethysmography, sonography and laryngography. All the patients were decannulated. A substantial improvement in breathing with a virtually unchanged voice was achieved in 145 cases. The good functional results are attributed to the fact that the vocal cord substance is retained and that a functionally active vocal cord is achieved. A narrow larynx requires the larger area of resection of false cord. The resected area depends upon the width of the larynx.
