All patients are very concerned about the cosmetic impact of neck scarring after thyroid surgery, indeed thyroid surgery is usually performed through a neck incision and therefore inevitably leaves scars on the neck. How to improve the cosmetic effect of thyroid surgery has been extensively studied by more scholars. Currently, the main modalities of thyroid surgery include conventional thyroid surgery, total laparoscopic thyroid surgery, and laparoscopic-assisted thyroid surgery. Because of the limitation on the patient’s body size, the size of thyroid nodules and the size of the gland, the laparoscopic surgery is particularly demanding on the operating skills of the surgeon in order to accomplish lymph node clearance and reduce postoperative complications. For conventional thyroid surgery, the suture method of cosmetic surgery has been borrowed to improve the fineness of suture, whether it is absorbable or not, the level of suture, the spacing of suture, etc., so that the incision of thyroid surgery gradually tends to be cosmeticized. The application of anti-adhesion glue in recent years has also been a significant improvement in the adhesion of skin scars. Generally speaking, as long as the patient does not belong to the scar hyperplasia skin type, the surgery can obtain better cosmetic results.
