The Thyroid Gland01:23

The Thyroid Gland

6.5K
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

7.0K
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...

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

4.9K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

The Parathyroid Glands00:59

The Parathyroid Glands

4.2K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Chronic Pharyngitis01:23

Chronic Pharyngitis

10.5K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

The Hyoid Bone01:12

The Hyoid Bone

4.5K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Summary
This summary is machine-generated.

Forgotten goitre, a rare mediastinal thyroid remnant after thyroidectomy, requires thorough preoperative imaging to prevent recurrence. This study reports 5 cases, emphasizing sternotomy for reoperation and complete initial thyroidectomy.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Medical Imaging

Background:

  • Forgotten goitre (FG) is a rare mediastinal remnant of thyroid tissue discovered post-thyroidectomy.
  • This condition is exceptionally uncommon, necessitating case reports and literature reviews for understanding.

Purpose of the Study:

  • To present 5 surgical cases of forgotten goitre.
  • To review existing literature on mediastinal thyroid remnants after total thyroidectomy.

Main Methods:

  • Retrospective review of patients with retrosternal goitre from 2010-2020.
  • Analysis of patient demographics, surgical history, imaging (radiography, CT, MRI), surgical approach, pathology, and complications.
  • Identification of 5 patients who underwent surgery for forgotten mediastinal goitre.

Main Results:

  • Five patients (3 female, 2 male; mean age 46.2 years) underwent surgery for FG.
  • Symptoms included dyspnea and dysphonia; 2 patients were asymptomatic.
  • Average time from thyroidectomy to reoperation was 4.3 years; goitre size ranged from 7-12 cm on CT. All required sternotomy, with one instance of transient recurrent laryngeal nerve palsy.

Conclusions:

  • Forgotten goitre is an extremely rare post-thyroidectomy complication.
  • Thorough preoperative imaging is crucial for preventing FG and associated morbidities.
  • Complete initial thyroidectomy and meticulous surgical technique are vital.
