Vocal cord polyps are a relatively common type of ENT (Ear, Nose, and Throat) disorder. For larger polyps where conservative treatment with medication is ineffective, surgical treatment should be considered. Currently, the main surgical procedure is the excision of vocal cord polyps under a supported laryngoscope, which requires general anesthesia. This is because the procedure is difficult for patients to endure without general anesthesia, as the supported laryngoscope is a type of metal tube that needs to be inserted through the mouth into the pharynx. Local anesthesia would be insufficient as patients might struggle to cooperate and tolerate the pain or nausea, hence general anesthesia is necessary for the surgery.
