[Bilateral paralysis of the vocal cords treated with endolaryngeal arytenoidectomy].

Bilateral paralysis of the vocal cords is a serious condition in which even slight oedema of the mucosa may endanger the patient's life. Bilateral paralysis of the vocal cords is most frequently due to thyroid operations but intubation, neuritis etc are among the other causes. Tracheostomy is nearly always necessary. In an attempt to render removal of the tracheal cannula possible with retention of vocal function, the authors have performed endolaryngeal arytenoidectomy. This intervention was carried out in 28 patients. In 23 of these the cannula could be removed while various conditions prevented removal of the cannula in the remaining five patients. The authors consider that arytenoidectomy is a good form of treatment of bilateral paralysis of the vocal cords involving only a slight risk. Thereafter, there are good chances for removal of the cannula with simultaneous retention of vocal function.
