The time to start cryopathology for thyroid surgery is not certain and needs to be determined on a case-by-case basis, possibly 1 to 3 hours after the start of surgery. When a malignant tumor lesion is present in the thyroid gland, the lesion can be removed surgically. Frozen pathology testing is usually required during surgery. The timing of cryopathology depends on the surgical procedure. If the lesion is a deep thyroid lesion, it is usually cut open about 1 to 3 hours after the start of the surgery and sections are selected for cryopathology. If the patient is an anterior thyroid lesion, the procedure is relatively simple and usually takes about one hour after anesthesia is administered to cut the lesion and select sections. After thyroid surgery, it is important for the patient to take good care of the wound area to avoid infection. If you feel unwell after thyroid surgery, you should seek medical attention promptly to avoid delaying your condition.
