A thyroidectomy is an operation that involves the surgical removal of all or part of the thyroid gland. Surgeons often perform a thyroidectomy when a patient has thyroid cancer or some other condition of the thyroid gland (such as hyperthyroidism).Other indications for surgery include cosmetic (very enlarged thyroid),or symptomatic obstruction (causing difficulties in swallowing or breathing). One of the complications of "thyroidectomy" is voice change and patients are strongly advised to only be operated on by surgeons who protect the voice by using electronic nerve monitoring. Most thyroidectomies are now performed by minimally invasive surgery using a cut in the neck of no more than 2.5 cms(1 inch). The thyroid produces several hormones, such as thyroxine (T4), triiodothyronine (T3) and calcitonin. After the removal of a thyroid patients usually take prescribed oral synthetic thyroid hormones to prevent the most serious manifestations ofthe resultant hypothyroidism.
Less extreme variants of thyroidectomy include:
"hemithyroidectomy" (or "unilateral lobectomy") -- removing only half of the thyroid
"isthmectomy" -- removing the band of tissue (or isthmus) connecting the two lobes of the thyroid
A "thyroidectomy" should not be confused with a "thyroidotomy" ("thyrotomy"), which is a cutting into (-otomy) the thyroid, not a removal (-ectomy) of it. A thyroidotomy can be performed to get access for a median laryngotomy, or to perform a biopsy. (Although technically a biopsy involves removing some tissue, it is more frequently categorized as an -otomy than an-ectomy because the volume of tissue removed is minuscule Indications
Malignancy (see Thyroid neoplasm)
Goiter which is untreatable by medical methods
Severe hyperthyroidism refractory to conservative treatment
