Because thyroid surgery is usually discharged 2-3 days after surgery, the results of paraffin pathology report are often not yet available, patients can come to the hospital a week after surgery to check the results of paraffin pathology report, not only on the basis of intraoperative frozen pathology results to decide the next treatment plan, because intraoperative frozen pathology and final paraffin pathology have certain errors, and sometimes there are “benign” tumors become “malignant” tumors. The results of intraoperative frozen pathology and final paraffin wax pathology may be inaccurate, and sometimes “benign” tumors may become “malignant” tumors. Currently, thyroid surgery is usually performed with intradermal sutures, so patients should come to the hospital 5-6 days after surgery to remove the sutures and check the wound healing status. After discharge, patients should pay attention to keep the wound dry. If there is any wound bleeding and oozing or redness, swelling and pain, they should come to the hospital in time. Try not to tilt your neck after stitch removal to avoid the possibility of wound dehiscence, especially for patients with larger wounds. Patients with postoperative thyroid cancer must take oral thyroxine (such as eugenol) for replacement or suppressive therapy. While some patients with benign tumors who underwent bilateral thyroid surgery also need oral eugenol replacement therapy, patients with unilateral benign thyroid tumors mostly do not need to take the drug because the hormones produced by the remaining thyroid tissues are sufficient to meet the body’s needs. For patients with nodular goiter or benign adenoma whose thyroid gland was not completely removed during surgery, thyroid ultrasound and thyroid function should be reviewed regularly at the outpatient clinic after surgery because there is a possibility of secondary tumor or even malignant tumor in the remaining thyroid tissue. Patients with hyperthyroidism should also have their thyroid function checked regularly in the clinic to check for recurrence or hypothyroidism. Most of the postoperative patients with combined hoarseness or choking cough are due to tissue edema and nerve compression and pulling, which can generally be recovered after 3-6 months. Follow-up time: generally 2-3 weeks after surgery to outpatient checkups, after the thyroid hormone level is adjusted to a stable state can gradually transition to six months or even once a year outpatient follow-up. Follow-up content: Thyroid ultrasound and thyroid function are the main content of follow-up, and CT and nuclear examination are available if necessary. After thyroid cancer surgery, chest X-ray and whole body bone scan should be reviewed regularly. Iodized salt and seafood can be consumed in moderation if not otherwise indicated.
