Summary
Acquired external auditory canal stenosis, though uncommon, involves inflammatory changes leading to medial canal fibrosis. Surgery is the primary treatment for complete obstruction, but understanding inflammation may yield new medical therapies.
Area of Science:
- Otolaryngology
- Pathophysiology
Background:
- Acquired external auditory canal stenosis is an uncommon but recognized clinical entity.
- Multiple etiologies contribute to the development of this condition.
Purpose of the Study:
- To review the causes, pathogenesis, assessment, and management of acquired external auditory canal stenosis.
Main Methods:
- Review of existing literature on external auditory canal stenosis.
- Analysis of histological and imaging studies.
Main Results:
- Histology and imaging reveal a common inflammatory cascade leading to medial canal fibrosis as the primary pathogenesis.
- Complete external auditory canal obstruction necessitates surgical intervention.
Conclusions:
- The pathophysiology of acquired external auditory canal stenosis is increasingly understood.
- Improved medical and surgical treatments may arise from a better grasp of the underlying inflammatory processes.

01:16Tracheostomy Care I: Pre-procedural Steps
A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.

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...

01:26Mitral Stenosis III: Medical Management
Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...
01:27Mitral Stenosis IV: Nursing Management
A comprehensive nursing assessment is essential for patients with valvular heart disease, which involves any dysfunction of the heart valves that could impact blood flow and overall heart function.Subjective Data Collection:Chief Complaint and Present Illness: Start with the patient's primary concerns, focusing on the onset, duration, and progression of cardiac symptoms such as dyspnea, fatigue, chest pain, and palpitations.Past Medical History: Collect detailed information on any previous...
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...

01:25Tracheostomy 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.
