[Surgical treatment of stenosing diseases of the larynx].

The author reports on the methods and results of the last 10 years in the treatment of pseudo-paralysis caused by the adhesions and scars in the interary region and in the commissura posterior-bilateral vocal cord paralysis and severe scarred laryngeal stenoses. During the stated period 68 patients were operated on. 4 patients were treated by an endolaryngeal approach for scarred adhesions developing in the interary region or in the commissura posterior. The operation was successful in all 4 patients. In 4 cases of laryngeal stenoses resulting from bilateral vocal cord paralysis, the Réthi-type operation was performed successfully in each case. In 33 cases, of which 32 could be analysed, the laryngo-microsurgical latero-fixation method was applied, with or without arytaenoidectomy, based on the endo-extralaryngeal suture technique developed by the author in previous animal experiments. In 29 patients the cannula was successfully removed after the endoscopic operations. 27 patients were operated on severe laryngeal stenoses. Of the 27 patients 24 had the cannula removed after the operations. In 3 patients the operations proved unsuccessful, and in these cases further operations are necessary.
