Summary
Arytenoid subluxation/dislocation (AS/AD) is a laryngeal disorder often caused by intubation. Prompt diagnosis and surgical relocation, successful in 80% of cases, are key to effective management.
Area of Science:
- Otolaryngology
- Laryngology
- Surgical Pathology
Background:
- Arytenoid subluxation/dislocation (AS/AD) is a recognized complication following endotracheal intubation.
- Persistent hoarseness is the most common presenting symptom.
Purpose of the Study:
- To review current diagnostic, therapeutic, and prognostic controversies in AS/AD management.
- To synthesize evidence from the recent international literature.
Main Methods:
- Systematic review of the last 20 years of international literature.
- Inclusion of 20 studies encompassing 471 cases of AS/AD.
- Analysis of retrospective case series.
Main Results:
- AS/AD is an iatrogenic condition, occurring in at least 0.01% of intubated patients.
- Diagnosis commonly involves video-laryngoscopy and CT scans; laryngeal electromyography aids in differentiating from vocal fold paralysis.
- Surgical relocation achieved an approximately 80% success rate.
Conclusions:
- AS/AD is a treatable mechanical laryngeal disorder requiring prompt diagnosis.
- Further clinical trials and multi-center studies are needed to establish definitive management guidelines.

401
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

01:21Larynx
3.7K
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,...

267
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

362
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...
