Thyroid disease is a common clinical condition with a higher incidence in women than in men, and is most common in women aged 20-40. Traditional thyroid surgery leaves a 6-10 cm long “suicide” surgical scar on the front of the neck, while the neck and face are the exposed parts of the body. With the rapid development of the economy, people’s living standards and aesthetic requirements are improving. In recent years, the rapid development of lumpectomy instruments and technology has provided a technical guarantee to meet this requirement of patients. In response to this situation, the Thyroid Treatment Center of the Fifth Hospital has taken the lead in successfully performing lumpectomy thyroid surgery in the city. The advantages of lumpectomy thyroid surgery: the three small incisions are chosen on the upper edge of the areola and the sulcus on both sides, which are relatively hidden and leave a small transverse scar of about 1 cm in the sulcus and no scar on the exposed neck; the problem of bleeding is solved by the excellent hemostasis effect of the ultrasonic knife, which is applied to cut the thyroid blood vessels and Moreover, unlike the electric knife, the ultrasonic knife does not produce electric current and rarely causes thermal damage to the nerves and parathyroid glands, which can greatly shorten the operation time and improve the safety of the operation; coupled with the magnification of the lumpectomy, the local anatomical structure is very clear, and the superior laryngeal nerve, the recurrent laryngeal nerve and the parathyroid glands can be clearly revealed, and as long as they are operated properly, few The local anatomy is very clear, and the superior laryngeal nerve, recurrent laryngeal nerve and parathyroid gland can be clearly revealed. The postoperative recovery is fast and the patient can be discharged in 3-5 days. Indications for surgery: 1. thyroid adenoma; 2. thyroid cyst; 3. nodular goiter (single or multiple, preferably diameter)
