Thyroid cysts are not a major clinical procedure and are common. The vast majority of thyroid cysts are benign diseases and the majority of thyroid cysts are not malignant tumors. For thyroid cysts with a diameter of more than 3 cm, surgery is recommended when they cause straining symptoms or compression of the thyroid envelope. If it is limited to unilateral, unilateral thyroidectomy can be performed. If it is bilateral, bilateral thyroidectomy can be considered for the purpose of cure. You can be discharged from the hospital in 3-5 days after surgery and recover well. At present, in tertiary care hospitals, complications and mortality of thyroid cyst surgery are minimal and the operation takes about 1-2 hours, so thyroid cyst is not a major surgery in clinical practice.
