The recovery time after thyroid cancer surgery is closely related to the size of the tumor, the surgical method, the presence of postoperative complications and the patient’s general condition, etc. Most patients need about 1 week to fully recover. If lateral lymph node dissection is not done, unilateral or bilateral radical thyroid cancer surgery usually has a small surgical wound, and a neck drain is usually placed after surgery, which can be discharged 1-3 days after surgery and can be recovered about 1 week after removal of the tube. If lateral lymph node dissection is done, due to the relatively higher risk of postoperative lymphatic leakage and celiac leakage, the tube is usually removed and discharged about 1 week after surgery. If the patient has postoperative complications, such as celiac leakage, the recovery time after surgery will be relatively longer. Since the thyroid gland is more extensively resected, thyroxine deficiency may exist after surgery, so thyroxine is usually required for life after radical thyroid cancer surgery to maintain the body’s thyroxine level to avoid causing hypothyroidism symptoms; for differentiated thyroid cancer among them, including papillary and follicular carcinoma, taking thyroxine makes the thyroid stimulating hormone level lower, which can reduce the probability of recurrence. It takes some time to adjust the medication.
