Stridor is a harsh, wheezy, or rough respiratory sound most often heard on inspiration to indicate laryngeal, subglottic, or tracheal partial obstruction or stenosis. Compare with involuntary inspiratory phonation.
Tracheal Stenosis, before and after Tracheal Resection and Primary Reanastomosis
Local Rather than Topical Anesthesia can Permit Fairly Major Tracheal Surgery
Using Your EARS to Understand Airway Narrowing
A narrowing anywhere in the breathing “pipe” that leads to the lungs causes shortness of breath, typically with harsh inspiratory noise on exertion. Such a narrowing can follow injury, intubation, cancer treatment, auto-immune disorders, etc.
It is possible to gain an immediate understanding of the magnitude of the airway narrowing within minutes by using a simple test “graded” with one’s ears. The severity of the problem can be understood before any examination or X-ray evaluation.
