A lobectomy of the thyroid gland A total thyroidectomy. Hemithyroidectomy — Entire isthmus is removed along with 1 lobe. Done in benign diseases of only 1 lobe. Subtotal thyroidectomy — Removal of majority of both lobes leaving behind 4-5 grams (equivalent to the size of a normal thyroid gland) of thyroid tissue on one or both sides—this used to be the most common operation for ...
Operations involve removal of the thyroid gland (thyroidectomy) either as a part of the gland (lobectomy or hemithyroidectomy), or the whole gland (total thyroidectomy). Incomplete resections (sub-total or near total thyroidectomy) are also infrequently performed, but are disfavored by most surgeons [citation needed].
The Revised 2009 American Thyroid Association guidelines for papillary thyroid cancer state that the initial procedure should be near-total or total thyroidectomy. Thyroid lobectomy alone may be sufficient treatment for small (<1 cm), low-risk, unifocal, intrathyroidal papillary carcinomas in the absence of prior head and neck irradiation or ...
Thyroid disease is a medical condition that affects the structure and/or function of the thyroid gland. The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ. These hormones normally act in the body to ...
Most people with thyroid cancer do not have symptoms at the time of diagnosis and thyroid nodules and thyroid cancer is usually found incidentally on imaging of the neck. [ 10 ] [ 14 ] Up to 65% of adults have small nodules in their thyroids, but typically under 10% of these nodules are found to be cancerous. [ 15 ]
If the nodule is malignant or has indeterminate cytologic features, it may require surgery. [2] A thyroidectomy is a medium-risk surgery that can result in complications if not performed correctly. Problems with the voice, nerve or muscular damage, or bleeding from a lacerated blood vessel are rare but serious complications that may occur.
In thyroid cancer or Graves' disease, ablation therapy with radioactive iodine (131 I) can be used to remove trace thyroid tissue that may remain after thyroidectomy (surgical excision of the gland). For 131 I therapy to be effective, the trace thyroid tissue must be avid to iodine, which is achieved by elevating the person's TSH levels. [6]
A lobectomy of the lung is performed in early-stage non-small cell lung cancer patients. [2] [3] It is not performed on patients that have lung cancer that has spread to other parts of the body. Tumor size, type, and location are major factors as to whether a lobectomy is performed. This can be due to cancer or smoking.
