The Thyroid Gland01:23

The Thyroid Gland

7.0K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

7.1K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Hyperthyroidism I: Introduction01:25

Hyperthyroidism I: Introduction

30
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

Hyperthyroidism II: Pathophysiology

28
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH...

Graves Disease II: Pathophysiology01:24

Graves Disease II: Pathophysiology

26
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor,...

Hypothyroidism II: Pathophysiology01:23

Hypothyroidism II: Pathophysiology

26
Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Otolaryngology

Background:

  • Less-than-total thyroidectomy reduces risks like hypothyroidism and nerve injury.
  • Re-intervention (redo surgery) is sometimes mandatory due to unsuspected carcinoma or disease progression.
  • Surgical decisions for redo thyroid surgery are personalized, considering multidisciplinary input and surgical team expertise.

Purpose of the Study:

  • To review recently published data on redo thyroid surgery.
  • To discuss current techniques, complications, and emerging trends in thyroid re-intervention.

Main Methods:

  • A narrative review of English-language original articles from PubMed.
  • Search terms included "redo thyroid", "thyroidectomy", and "thyroid surgery".
  • Publication timeframe: January 1, 2020, to July 20, 2024.

Main Results:

  • Ten studies were identified, showing diverse complications and applications in redo thyroid surgery.
  • Techniques discussed include recurrent laryngeal nerve monitoring and alternative incisions.
  • Robotic-assisted re-intervention is a focus of recent research, with expected expansion.

Conclusions:

  • Redo thyroid surgery requires careful consideration of risks and benefits.
  • Further research and multifactorial models are needed for optimal decision-making and technique selection.
  • Robotic approaches show promise for future redo thyroid interventions.
