Whether a thyroidectomy is considered major surgery needs to be determined on a case-by-case basis. Removal of a thyroid lesion or lobectomy is generally not considered a major surgery; total removal of the thyroid gland and removal of nearby lymph nodes are considered larger surgeries. According to the grading of the surgery, thyroid lesion removal or simple thyroid lobectomy is generally classified as a level 2 or 3 surgery, which removes more limited tissues and is not considered a major surgery; while radical thyroid cancer surgery or total thyroidectomy is classified as a level 4 surgery, which is a major surgery and requires higher requirements for the surgeon. Patients who have been diagnosed with thyroid disease and need thyroidectomy should actively cooperate with the surgeon’s operation process and make good preoperative preparations, which will help to avoid intraoperative and postoperative complications.
