Vocal polyp removal alone can be completed within 10 minutes, difficult cases may need to extend for about half an hour, plus anesthesia, sterilization and other time of about 1 hour. In order to meet the surgeon’s operation, as well as to reduce the patient’s pain, vocal cord polyp surgery mostly need to operate under general anesthesia, which also requires a series of preparations for general anesthesia, such as admission to the room vital signs monitoring, informed consent for anesthesia, endotracheal intubation, and so on, and this process takes about half an hour. Before the removal of vocal polyps, the surgeon will disinfect, put the support laryngoscope, completely expose the vocal folds, and then remove the polyp under clear vision, which can usually be completed in about 10 minutes. However, when it comes to larger polyps with extensive roots and intraoperative bleeding, it may take up to 30 minutes or even longer to complete the surgery. In addition, the duration of vocal polyp surgery is determined by the surgeon’s proficiency and the patient’s awakening from anesthesia.
