Summary
Arytenoid cartilage dislocation is a rare laryngeal injury. Transesophageal echocardiography (TEE) probe insertion during cardiac surgery may cause this injury, even with subtle force.
Area of Science:
- Laryngology
- Cardiology
- Anesthesiology
Background:
- Arytenoid cartilage dislocation and subluxation are uncommon laryngeal injuries, often linked to upper aerodigestive tract instrumentation.
- The exact cause of these injuries is frequently challenging to pinpoint.
Observation:
- A case of arytenoid dislocation occurred after cardiac surgery involving transesophageal echocardiography (TEE).
- This prompted a review of cricoarytenoid joint injury mechanisms.
Findings:
- Even minimal force can dislocate the arytenoid cartilage.
- Careless TEE probe insertion is a potential mechanical cause of arytenoid dislocation and subluxation.
Implications:
- Transesophageal echocardiography (TEE) is increasingly used in cardiac surgery for monitoring.
- The incidence of TEE-related arytenoid injuries may rise; understanding pathophysiological risks is crucial.
- Informed consent for TEE monitoring in cardiac surgery must include potential risks.

01:28Tracheostomy: 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...

01:30Cardiopulmonary 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...
01:21Tracheostomy 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...

01:21Larynx
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...

01:25Tracheostomy 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...

01:12The Hyoid Bone
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...
