Vocal fold polyps are a common cause of hoarseness, and are often seen as thickened tissue protrusions on the edges of the vocal folds, which can be large or small, with tips or wide bases, light red or grayish white, mostly unilateral, with the onset of inflammation, trauma, excessive vocalization or allergic reactions. Since most polyps are difficult to disappear with medication alone, they always need to be removed surgically. There are two usual surgical methods: one is to use intravenous compound anesthesia (general anesthesia) for tracheal intubation and remove polyps with surgical forceps or scissors or laser under a supported laryngoscope; the other is to use mucosal surface anesthesia (epi-anesthesia) and remove polyps with the help of electronic laryngoscope or bronchoscope in the awake state. The latter method is easy, fast, low cost, less traumatic, and the monitoring can clearly magnify and record the whole procedure, while observing the vocal fold closure and the surgical effect through pronunciation, which is the ideal treatment for small and medium polyps.
