Throidectomy The thyroid gland is a butterfly-shaped organ and is composed of two lobes, one on the right and the left as the wings, and the narrow connecting isthmus as the body. The thyroid is one of the larger endocrine glands, weighing 2-3 grams in neonates and 25 grams in adults, and is increased in pregnancy.

- The thyroid cartilage is the largest of the nine cartilages that make up the laryngeal skeleton, the cartilage structure in and around the trachea that contains the larynx.he thyroid cartilage is a cartilage that sits in front of the larynx and above the thyroid gland. The cartilage is composed of two halves, which meet in the middle at a peak called the laryngeal prominence, also called the Adam's apple. In the midline above the prominence is the superior thyroid notch.

Thyroid Operations Thyroid Lobectomy with Isthmusectomy. This simply means removal of a thyroid lobe and the isthmus (the part that connects the 2 lobes). This removes more thyroid tissue than a simple lobectomy, and is used when a larger margin of tissue is needed to assure that the problem has been removed.

Picture of the Thyroid © 2014 WebMD, LLC. All rights reserved. The thyroid is a butterfly-shaped gland that sits low on the front of the neck. Your thyroid lies below your Adam’s apple, along the front of the windpipe. The thyroid has two side lobes, connected by a bridge (isthmus) in the middle. When the thyroid is its normal size, you can’t feel it. Brownish-red in color, the thyroid is rich with blood vessels.

- Thyroid cysts are regions of the thyroid that are enlarged and filled with fluid. They may be small (1 cm) or sometimes very large and can develop slowly or arise suddenly. Thyroid nodules can also degenerate and become fluid-filled sacs entirely or have a combination of solid and cystic areas.ver a period of time, these cysts may shrink in size. Sometimes, they can become larger and unsightly and cause discomfort. If they do not enlarge in size and cause any problem, they can be left alone. However, complications like bleeding into the cyst can occur and the cyst can suddenly enlarge in size.

What Is Thyroid Cancer? The thyroid gland. The thyroid gland is below the thyroid cartilage (Adam’s apple) in the front part of the neck. In most people, the thyroid cannot be seen or felt. It is butterfly shaped, with 2 lobes — the right lobe and the left lobe — joined by a narrow isthmus (see picture below).

Diagnosis Hypothyroidism: Six Questions to Ask Your Doctor The TSH test is the most commonly used test for diagnosis and management of hypothyroidism in the United States. This measure is the range of test values deemed to reflect a normal population. At the lab used by my doctor, the TSH reference range is 0.5 to 4.5 as of 2015. A TSH value of less than 0.5 is considered hyperthyroid (overactive thyroid), while a TSH value of more than 4.5 is considered potentially hypothyroid (underactive thyroid).

Normal Size of Thyroid Gland What is the Normal Size of the Thyroid Gland. The normal size, or range of size, of the thyroid gland in adults is 4 to 4.8 cm x 1.0 to 1.8 cm x 0.8 to1.6 cm. As mentioned above, the thyroid gland is one of the largest endocrine glands found in humans.The weight of this gland in neonates is about 2-3 grams.In case of adults, the normal weight of the thyroid gland should be in between 18-20 grams. The size of the thyroid gland can increase due to certain conditions like pregnancy or smoking frequently.These conditions are not termed as abnormal.he weight of this gland in neonates is about 2-3 grams.

History The thyroid gland usually grows outward because of its location anterior to the trachea (see the image below). Occasionally, the thyroid wraps around and compresses the trachea and/or esophagus or extends inferiorly into the anterior mediastinum. Multinodular goiter. On visual inspection of the neck (image on left), this patient appears to have a goiter. The computed tomography scan (image on right) shows the asymmetrical goiter, measuring 9.3 x 7.4 cm, with tracheal deviation, although no tracheal obstruction is present.

Thyroid Gland: Frequently Asked Questions A thyroid nodule is a growth within the thyroid gland. Thyroid nodules are extremely common, and nodules large enough to be felt can be seen in 5 to 10% of women and 1 to 5% of men. If imaging is performed of your thyroid, smaller nodules that cannot be felt can be found in over 50% of patients.

Thyroid Nodules Thyroid nodules are growths in the thyroid. Thyroid nodules are very common and occur in up to 15 to 30% of the US population. Like most thyroid diseases, they are more common among women than men. In addition, the chance of having a thyroid nodule increases with age and by the time a woman is 60, there is a 60% chance that she will have a thyroid nodule.
