A surgical procedure to remove the thyroid gland from the body.
After the diagnosis, the doctor recommended a thyroidectomy to treat the patient's condition.
Thyroidectomy → It is formed from "thyroid" (from Greek "thyreoeides", meaning shield-shaped, referring to the thyroid gland's shape) and "-ectomy" (from Greek "ektome", meaning excision or removal). The word describes the surgical removal of the thyroid gland.
Think of the 'shield-shaped' ('thyreoeides') gland being 'removed' ('-ectomy') during surgery — that's what thyroidectomy means.
