Abstract:
Objective To compare the clinical effect between CO2-1aser assisted and cold instrument assisted suspension laryngoscopic surgery for vocal fold cyst.Methods From January, 2011 to December, 2014, 72 patients with vocal fold cyst, which diagnosed by strobolaryngoscopy, were randomly divided into CO2-1aser assisted group and cold instrument group.Strobolaryngoscopy, acoustic analysis and perceptual voice analyses were performed on each patient before surgery, 1 month, and 3 months after surgery, respectively.Results All operations were successfully completed.The complete vocal fold cyst resection rate of CO2-1aser assisted group was significantly higher than cold instrument group (29/36, 80.5％ vs 21/36, 58.3％, P ＜ 0.05), especially the left vocal fold cyst (13/16, 81.3％ vs 9/19, 47.4％, P ＜ 0.05).The complete right vocal fold epidermoid cyst resection rate was significantly higher than retention cyst (17/19, 89.4％ vs 11/18, 61.1％, P ＜ 0.05).Two recurrent cases were found in cold instrument group but no recurrent cases in CO2-laser assisted group (0/36, 0％ vs 2/36, 5.6％, P ＞ 0.05).Correlation analysis showed that vocal fold cyst recurrence was related to complete resection rate and has no relation with surgical methods, histopathological types and position.Subjective and objective assessment of voice quality in preoperative, 1-month postoperative and 3-month postoperative were similer between CO2-1aser assisted group and cold instrument group (P ＞ 0.05).Conclusion The CO2-laser assisted suspension laryngoscopic surgery for vocal fold cyst, can increase the surgical precision, reduce the left hand impact, improve the complete resection rate and reduce the recurrence rate.
