Abstract

Microdissection electrodes (MEs) have previously been used to perform endoscopic cordectomies.

We designed a prospective study in order to compare the ME with the CO2 laser technique. Over two years, 20 patients with T1 glottic carcinoma were operated on with CO2 laser and 20 with MEs. The device was chosen alternatively for each new patient. Two patients in both treatment groups had slight glottic incompetence. Three patients in each group showed web formation. The only granuloma was observed in a CO2 laser patient. Seven of the ME patients developed slight dysphonia, 10 developed medium grade dysphonia and three developed severe dysphonia. Seven of the CO2 laser patients developed slight dysphonia, seven developed medium grade dysphonia and six developed severe dysphonia. No statistically significant differences were observed on comparing the grade of dysphonia with patient age, T stage, type of cordectomy or surgical device.

We consider the ME to be a useful and inexpensive alternative to CO2 laser.
