Larynx

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 Decannulation

Tracheostomy Decannulation

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...

Tracheostomy: Procedure and Tubes

Tracheostomy: Procedure and Tubes

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...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...

Trachea

Trachea

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...

Summary

A rare penetrating neck injury caused complete cricoid cartilage transection, complicating airway management. Surgical reconstruction successfully restored both breathing and voice in this case of acute laryngeal injury.

Area of Science:

Otolaryngology
Trauma Surgery
Emergency Medicine

Background:

Acute laryngeal injury is a rare but life-threatening condition.
Airway management is often challenging in patients with laryngeal trauma.
Penetrating neck injuries are less common causes of laryngeal injury compared to blunt trauma.

Observation:

A case of a penetrating neck injury involving a deep slash wound from a knife.
Complete transection of the cricoid cartilage and laryngotracheal separation were observed.
Initial management included securing the airway and performing a tracheostomy.

Findings:

Surgical exploration revealed the cricoid cartilage was horizontally divided into two parts.
Anastomosis of the cartilaginous framework was performed.
Post-operatively, fibreoptic laryngoscopy showed bilateral vocal cord paralysis, which resolved over two months.

Implications:

Meticulous surgical reconstruction is crucial for optimal outcomes in severe laryngeal trauma.
Successful surgical repair can restore both respiratory and phonatory functions.
This case highlights the possibility of recovery from complete cricoid cartilage transection with prompt surgical intervention.
