Quick Summary

A thyroidectomy is the surgical removal of all or part of the thyroid gland. This procedure is often performed to treat conditions such as hyperthyroidism, which is the overproduction of thyroid hormone. Other reasons for a thyroidectomy can include large goiters or thyroid tumors.12

The surgery can be performed using various techniques, and the extent of removal depends on the specific medical condition. After a thyroidectomy, patients may require lifelong hormone replacement therapy to manage hypothyroidism, which is the underproduction of thyroid hormone.2
