The best time for postoperative recovery of vocal cord cancer is 5~10 days after the operation, but the time for postoperative recovery of vocal cord cancer varies from patient to patient because of different physical conditions and nursing conditions. If the trauma caused by removing the cancerous part is relatively small when the patient undergoes the surgery, the wound will be easier to recover. However, if the scope of trauma is larger, it may take longer time for the wound and voice to recover, and then the patient may not be able to communicate in a low voice until after ten days. It will be difficult for the voice to return to the same level as before. After vocal cord surgery, patients should pay attention to vocal rest, that is, do not talk for a long time, do not eat stimulating food and alcohol. Try to avoid swallowing foods that are too hard or too dry, such as nests and baked cookies.
