Thyroid tumor is a very common tumor of the head and neck. It is divided into benign thyroid tumor and malignant thyroid tumor depending on the nature of the pathology. Generally, the surgery for malignant thyroid tumor is a little more extensive, so the surgery will take longer, for example, the radical treatment of thyroid cancer plus lymph node dissection in the neck may take more than 2-3 hours. For example, radical thyroid cancer with lymph node dissection in the neck may take more than 2-3 hours. If the thyroid gland is simply removed, it may take about 1 hour. For benign thyroid tumors, the surgery may be less difficult, but after all, it is a tumor located in the neck, which is rich in blood vessels and nerves, so care should be taken to avoid damaging important nerves and blood vessels during surgery, and to ensure timely wound healing and prevent infection after surgery. For benign thyroid tumor, there is no problem if the wound heals in 5-7 days after surgery. In case of malignant tumors, other anti-tumor treatments may be required after surgery.
