Summary
Three-dimensional CT imaging aids in diagnosing and managing supraglottic stenosis, a rare airway obstruction. This technique provides detailed airway information for effective surgical intervention and improved patient outcomes.
Area of Science:
- Otolaryngology
- Medical Imaging
Background:
- Supraglottic stenosis is a rare airway obstruction, often misdiagnosed, requiring detailed anatomical information for effective management.
- Causes include radiation, trauma, autoimmune diseases, and caustic exposure, necessitating precise diagnostic methods.
Observation:
- A 78-year-old woman presented with severe dyspnea and hypercarbia due to supraglottic stenosis.
- Three-dimensional computed tomography (CT) imaging was used to visualize the tubular supraglottic stenosis.
Findings:
- The patient underwent tracheotomy and micro-laryngeal surgery with CO2 laser excision and mitomycin application.
- Post-operative recovery was uneventful, with significant improvement in symptoms of supraglottic stenosis.
Implications:
- Three-dimensional reconstructed CT images are valuable for airway management in supraglottic stenosis, complementing endoscopy and other radiological findings.
- This advanced imaging facilitates precise surgical planning and improves outcomes for patients with complex airway obstructions.

01:23Oxygen Delivering System III: Tracheostomy and T-piece
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

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...

01:21Tracheostomy 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...

01:30Cardiopulmonary 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...
