[Treatment of chronic cicatricial laryngeal stenosis (author's transl)].

Eighty severe cases of chronic laryngeal stenosis in patients aged 1--78 years, where all other treatment had failed, were operated upon with laryngofissure of the front and back wall of the larynx followed by excision of the stenosis scar tissue. An endolaryngeal prosthesis was inserted and left in position for four months. The clinical result was good in 69 patients but, for various reasons, unsuccessful in eleven. The results of the treatment was also investigated by spirometry and body plethysmography. Contraindications for this operation are presented. The mean follow-up time was 6.9 years.
