Efficacy of CO_2 laser treatment of vocal cord leukoplakia under phonomicrosurgery

Objective To investigate the efficacy and operation strategy of CO2 laser treatment of patients with vocal cord leukoplakia under phonomicrosurgery.Methods Forty-five patients were treated with CO2 laser phonomicrosurgery of mucosal epitheliumablation,mucosal stripping and partial resection of vocal cord,respectively.Results There were 24 vocal cord leukoplakia cases without dysplasia,13 cases with mild dysplasia(LIN1)and 8 cases with moderate to severe dysplasia(LIN2).Three cases recurred postoperatively and accepted twice or more operations successively.One case occurred canceration.Conclusion The CO2 laser phonomicrosurgery is a valuable treatment for patients with vocal cord leukoplakia.It has advantages of less trauma,quicker recovery and difficult to recurrence.However,the cases with dysplasia should be followed up closely.
