What is the difference between subtotal thyroidectomy and total thyroidectomy?

Subtotal thyroidectomy and total thyroidectomy generally refer to subtotal thyroidectomy and total thyroidectomy. Both are methods of treating thyroid cancer, but the scope of surgery is different.

1. Subtotal thyroidectomy: This surgery is suitable for patients with small tumors that have not invaded surrounding tissues or lymph node metastasis. During the operation, the doctor will remove the tumor and the normal thyroid tissue around it, and retain as much normal thyroid tissue as possible. This surgical method can reduce the occurrence of postoperative complications and preserve a certain degree of thyroid function. However, due to the small scope of the operation, there may be a risk of recurrence.

2. Complete thyroidectomy: This surgery is suitable for patients with large tumors that have invaded surrounding tissues or lymph node metastasis. During the operation, the doctor will remove the entire thyroid tissue and may need to perform a neck lymph node dissection. This surgical method can completely remove tumor cells and reduce the risk of recurrence. However, due to the large scope of the operation, it may have a certain impact on the patient's physiological function.

When choosing a surgical method, it is necessary to decide based on the patient's specific situation. If the tumor is small and has not invaded surrounding tissues or lymph node metastasis, subtotal thyroid cancer resection can be selected. If the tumor is large or has invaded surrounding tissues or lymph node metastasis, total thyroid cancer resection is required. A comprehensive evaluation and examination is also required before surgery to ensure the safety and effectiveness of the surgery.

Subtotal thyroidectomy and total thyroidectomy are two different treatment methods for different conditions. When choosing a surgical method, it needs to be decided based on the patient's specific situation and must be performed under the guidance of a doctor.
