The Thyroid Gland01:23

The Thyroid Gland

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...
Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

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...
Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Tracheostomy Care II: Procedure01:25

Tracheostomy Care II: Procedure

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask and...
Hyperthyroidism I: Introduction01:25

Hyperthyroidism I: Introduction

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: Pathophysiology01:27

Hyperthyroidism II: Pathophysiology

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 receptors...

Summary
This summary is machine-generated.

Thyroidectomy often causes voice changes, even with healthy laryngeal nerves. This study found voice alterations are more common after thyroid surgery than breast surgery, with orotracheal intubation being only one contributing factor.

Area of Science:

  • Otolaryngology
  • Endocrinology
  • Speech-Language Pathology

Background:

  • Voice alterations can occur post-thyroidectomy despite preserved laryngeal nerve function.
  • The impact of orotracheal intubation on voice changes requires further investigation.

Purpose of the Study:

  • To evaluate voice changes before and after thyroid surgery.
  • To assess the specific role of orotracheal intubation in post-thyroidectomy voice alterations.

Main Methods:

  • Prospective nonrandomized study comparing thyroidectomy patients with a breast surgery control group.
  • Utilized videolaryngoscopy, subjective and objective voice analysis, and Voice Handicap Index (VHI) questionnaires pre- and post-surgery.

Main Results:

  • Thyroidectomy patients showed larynx alterations (28%) and subjective voice changes (29.7%) more frequently than controls.
  • Acoustic analysis revealed increased voice turbulence index (VTI) in both groups, notably higher in the thyroidectomy group.
  • Voice Handicap Index (VHI) scores indicated more frequent voice complaints in the thyroidectomy group.

Conclusions:

  • Voice alterations are common after thyroidectomy, even with preserved vocal fold mobility.
  • These alterations are more prevalent compared to patients undergoing breast surgery.
  • Orotracheal intubation is identified as one of several factors contributing to voice changes.
