If the nodules in the neck are superficial lipomas, epidermoid cysts, hemangiomas and other benign lesions, the surgery will take 20-30 minutes if the nodules are removed under local anesthesia, and about 1 hour if the nodules are multiple. If the patient’s thyroid lumps protrude from the body surface and form neck nodules, the nature of the thyroid nodules is benign and the operation is relatively simple, without lymph node dissection, and the operation takes about 1.5 hours. If the nature of the nodule is malignant, lymph node dissection is required and the operation takes about 2 hours.
