Triamcinolone acetonide injection for laryngeal stenosis
The Journal of Laryngology and Otology
|October 1, 1975
Summary
Percutaneous intralesional injection of triamcinolone acetonide effectively treated acquired laryngeal stenosis. This minimally invasive approach provided satisfactory laryngeal airway and phonation for years in three patients.
Area of Science:
- Otolaryngology
- Laryngology
- Minimally Invasive Procedures
Background:
- Acquired laryngeal stenosis presents a significant challenge in otolaryngology.
- Traditional treatments can be invasive and associated with complications.
- Exploring novel, less invasive therapeutic options is crucial for improving patient outcomes.
Observation:
- Three patients with acquired laryngeal stenosis were treated.
- The intervention involved percutaneous intralesional injection of triamcinolone acetonide.
- Mirror laryngoscopy was utilized for precise delivery of the injection.
Findings:
- Successful treatment of acquired laryngeal stenosis was achieved in all three cases.
- The percutaneous intralesional injection method demonstrated efficacy.
- Patients experienced satisfactory laryngeal airway and phonation post-treatment.
Implications:
- This technique offers a promising minimally invasive alternative for managing acquired laryngeal stenosis.
- Long-term follow-up (2-6 years) suggests durable positive effects on airway and voice.
- Further research into this injection method could refine treatment protocols in laryngology.

01:11Direct-Acting Cholinergic Agonists: Therapeutic Uses
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren syndrome.
01:31Skeletal Muscle Relaxants: Therapeutic Uses
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...
01:22Trachea
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...

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...
