Objective : To explore the treatment of epiglottic cyst by Nd - YAGlaster. Method: Using Nd - YA-Glasterl26 patients of epiglottic cyst were treated. Result; 126 patients were followed up for 1 -5 years. Among them, 116 patients is cured including 12 cases with thicken of mucosa local and 2 cases with partial defect of epiglottic, which were cured 1 month later, and 8 cases recurrenced. Conclusion: Epiglottic cyst were eliminated by laster due to its laser thermo-therapy . It is improtant that appropriate power and irradiate time to prevent epiglottic cyst recurrenced or thickenof local mucosa, defect of epiglottic .
