Abstract:Objective To investigate the curative effect of laser resection of vocal cord cyst under suspension laryngoscope.Methods 21 cases of vocal cord cyst failed to be separated by microflap dissection, then the cyst wall of vocal cord cyst was removed by laser under laryngoscope, and the morphology of vocal cord, closure of glottis and improvement of hoarseness were observed by dynamic laryngoscope at 2 weeks, 2 months and 6 months after the operation.Results The operation was successful in 21 patients whose hoarseness was improved immediately after operation, without bleeding or asphyxia. Two weeks later, 16 were recovered well while 5 were still with hoarse voices, slightly edematous vocal cords and unsmoothed marginal mucosas. Eight weeks after operation, 20 cases resumed or were close to regular voice with flat and smooth edges of vocal cord under laryngoscopy; besides, one patient had poor voice suppression, persisted hoarseness and 1/3 of the anterior and middle vocal cords showed nodule like micro uplift. After half a year of follow-up,the above-mentioned patient with hoarseness, accompanied by vocal nodules, felt that his voice was acceptable; and without any case recurred. One case had cyst on the opposite side 5 months after operation, with no recurrence after complete removal by microflap dissection.Conclusion Laser supplementary excision of the residual vocal cord cyst wall under laryngoscopy can completely remove the lesion and retain the integrity of mucous membrane, which is beneficial to the recovery of vocal function, and is a good surgical method for the treatment of broken vocal cord cyst.
