Posterior cordotomy in bilateral vocal cord paralysis using monopolar microelectrodes and radiofrequency in 18 patients

Abstract

Posterior cordotomy is an option in the surgical treatment of bilateral vocal cord paralysis in adduction.

We present results obtained in 18 patients with bilateral vocal cord paralysis in adduction treated using microelectrodes terminal with tips in several angles, and a radiofrequency generator from 2008 to 2013.

The functional outcome was evaluated using postoperative spirometry, the decannulation time, and swallowing.

All patients except one were successfully decannulated and showed an increase in mid-inspiratory flow rates.

The angled shape of the ME tips permits a very good resection for cordotomy; ME and radiofrequency are an excellent alternative to CO2 laser.
