Larynx01:21

Larynx

5.2K
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,...

Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

4.0K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

The Thyroid Gland01:23

The Thyroid Gland

8.0K
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...

Tracheostomy Care II: Procedure01:25

Tracheostomy Care II: Procedure

1.8K
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...

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

8.3K
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...

Tracheostomy Decannulation01:21

Tracheostomy Decannulation

1.8K
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Summary

Total thyroidectomy using energy-based devices like Harmonic scalpel (HS) or LigaSure (LS) does not significantly impact long-term voice outcomes. Voice function returns to baseline levels within months, regardless of the device used.

Area of Science:

  • Otolaryngology
  • Endocrinology
  • Surgical Innovation

Background:

  • Voice dysfunction is a common concern after thyroidectomy, even without vocal fold paralysis.
  • Energy-based devices, including Harmonic scalpel (HS) and LigaSure (LS), are frequently employed in thyroid surgery.

Purpose of the Study:

  • To evaluate the long-term effects of total thyroidectomy using energy-based devices on voice quality.
  • To compare voice outcomes between Harmonic scalpel and LigaSure use.

Main Methods:

  • Prospective study of 92 patients undergoing total thyroidectomy for papillary thyroid carcinoma using HS or LS.
  • Comprehensive voice assessments including videolaryngostroboscopy, acoustic analysis, voice range profile, perceptual evaluation, and Voice Handicap Index-30 at multiple postoperative time points (1 week to 1 year).

Main Results:

  • No significant differences in voice parameters were observed between the HS and LS groups at long-term follow-up.
  • While early postoperative voice changes (worse scores in VRP, VPE, VHI-30) were noted within one month, these gradually returned to preoperative levels by one year.
  • No videolaryngostroboscopic abnormalities were detected postoperatively.

Conclusions:

  • Total thyroidectomy using either Harmonic scalpel or LigaSure results in comparable long-term voice outcomes.
  • Voice function generally recovers to baseline within one year, irrespective of the energy-based device utilized.
