A 25-year-old boy, Ah Shui (pseudonym), a villager from Guangdong, found a swollen neck more than 3 years ago, and initially did not take it seriously. This left lobe swelling had pushed the trachea severely to the right and was compressing the trachea, leaving only 0.3 cm at the narrowest part of the trachea. The mass, which was larger than an adult male fist, was completely removed and weighed 550 grams. Under the careful care of the medical staff, Ah Shui soon regained consciousness after receiving general anesthesia and began to eat and get out of bed that evening, with no surgical complications and a good recovery. Today, the healed Ah Shui has already returned to work and the family is living happily. The incidence of benign thyroid tumors remains high in recent years despite the rapid economic development and improvement of living standard in China, especially among female patients, which is closely related to environment, climate, diet, emotional stress and genetics. The majority of patients have small thyroid swellings, and there are still a few huge thyroid swellings after all. Surgery has been an effective treatment for thyroid tumors for more than 100 years, and has the advantage of precise efficacy in treating thyroid tumors.
