Abstract
It is difficult to perform operation for epiglottic diseases by conventional surgical method under microlaryngosopy. Bleeding can not be controlled and sometimes visual field is obstructed by blood. However most of epiglottic diseases can be operated without bleeding by using CO2 laser. We can get enough visual field under laser surgery. In some cases, for example, malignant tumor and big epiglottic cyst, we need not only CO2 laser but also bipolar coagulator to sotp bleeding from branches of upper laryngeal artery as same as in cases of tong cancer special laryngoscope. Epiglottic or vallecular cyst can be perfectly removed by this method and epiglottectomy also casily performed under microlaryngo-surgery.
