Summary
Sixty patients with subglottic stenosis of acquired and nonneoplastic origin were surgically managed by multiple open procedures. Follow-up ranged from 1 to 10 years. Fifty-seven patients had stable and excellent or good results, 2 of them after further surgery, 1 patient had to live with a retained tracheostomy indefinitively and the remaining 2 patients died.
While the whole spectrum of surgical modalities employed in this series may not be recommended with total conviction, the authors express their satisfaction with single resection and end-to-end anastomosis which yields invariably good and rapidly obtainable results (22 cases with complete success). Nevertheless, larnygeal enlargement seems to be essential in the case of upper glottic lesions (19 operations provided 19 successes) while primary resection with moulding plasties may be applicable to complex and extended stenoses (19 operations: 16 successful results and 3 failures).
With regard to the choice of operation, the authors emphasize the importance of careful preoperative assessment of the lesions which should assure adequate selection of therapeutic methods according to the degree of associated involvement of the trachea, glottis or supraglottic area.
Conservative measures including dilatation, electro-coagulation and laser-beam surgery are considered as palliative only, however, they may be useful either in the course of the patient's preparation or in order to achieve more successful postoperative results.
