The size of the thyroid surgery incision is an issue of great concern to patients with thyroid disease. Many patients consider and ask this question when they are hesitant to operate or not to operate, because after all, the neck is an important part of the human body’s appearance, and it affects everyone’s mentality and self-confidence in the work, life and social process to a greater or lesser extent. One of the things that people who have had surgery often do after surgery is to compare the size of the surgical incision, and sometimes you can even hear the words “my wound is big, so my surgery is also big; your incision is small, your surgery is small”. The larger the incision, the greater the exposure of the surgical field, the less difficult it is. In fact, among thyroid surgeons, there is a heated debate about the size of the thyroid incision. One argument is that the incision can be as small as possible to reduce the actual impact on the patient’s appearance and appearance after surgery, while ensuring the thoroughness and safety of the surgery. Another argument is that a large incision is preferable to a small one. A large incision exposes well, shows adequate surgical field, increases safety, may shorten the operation time, and a few centimeters larger incision has little impact on aesthetics. In fact, it is easy to make a few centimeters large, but every centimeter or even a few millimeters small is to pay a lot of people together with arduous exploration and unremitting efforts, including the renewal of consciousness, improvement of technology, renewal of instruments and so on. Today, modern medicine is developing, anesthesia technology is becoming more and more mature, surgical equipment and instruments have long been different from the past, surgery has long been not blood gauze up and down, blood fighting, blindly seeking fast “Little Lee flying knife” era, today more people in the pursuit of surgery fine, accurate, tiny trauma. Nowadays, lumpectomy-assisted thyroid surgery requires only a 2 cm incision, while an open surgery requires a minimum of 5-6 cm incision, which makes a significant difference in the visual aesthetics of a 2 cm incision. Also because of the visual magnification effect of the lumpectomy, the surgery has the potential to be more delicate and precise. The 21st century is the era of minimally invasive surgery, and thyroid surgery techniques are no exception. countless scholars, including scientists, have explored and invented new devices and techniques to eradicate disease while bringing minimal trauma to the body and heart.
