The right side of the neck is larger than the left side of the neck clinically, which is most often seen in thyroid disorders and usually requires further thyroid ultrasound as well as hematological thyroxine levels, including T3, T4, free T3, free T4, and TSH levels. If the ultrasound examination suggests that the thyroid mass is graded more than grade 4, it has become apparent to the naked eye that the right side of the neck is larger than the left side, and the thyroid mass has exceeded 3 cm, whether it is a benign thyroid nodule, thyroid adenoma or malignant thyroid cancer, local compression symptoms usually occur and prompt surgical treatment is required and intraoperative freezing is sent to rule out the possibility of malignant thyroid tumor. If malignant thyroid tumor is confirmed, further surgical treatment with radical thyroidectomy and combined with postoperative chemotherapy or even radiotherapy is usually required.
