Treatment of hypertrophic ventricular dysphonia with CO2 laser / 中国耳鼻咽喉头颈外科

ABSTRACT

[ABSTRACT]OBJECTIVETo study the clinical effect of CO2 laser in the treatment of hypertrophic ventricular dysphonia.METHODSFrom December 2011 to December 2013, 40 patients with hypertrophic ventricular dysphonia were treated in our department. Conservative treatment had no valid for all of them. All the patients were examined with strobolaryngoscope and voice analysis (including fundamental frequency, jitter, shimmer and harmonic to noise). After general anesthesia, the hypertrophic ventricular cords were excised with CO2 laser under suspension laryngoscope.RESULTS The Hoarseness were better in all the patients after operation. The ventricular cord and mucosal waves of the vocal cord were normal. The jitter and shimmer were lower than that before operation, but the fundamental frequency and harmonic to noise were higher than that before operation. There were no complications. CONCLUSIONThe treatment of hypertrophic ventricular dysphonia with CO2 laser under suspension laryngoscope is safe, reliable and practical.
