Symptoms of Laryngotracheal Stenosis
The most common symptom of laryngotracheal stenosis is gradually-worsening breathlessness (dyspnea) particularly when undertaking physical activities (exertional dyspnea). The patient may also experience added respiratory sounds which in the more severe cases can be identified as stridor but in many cases can be readily mistaken for wheeze. This creates a diagnostic pitfall in which many patients with laryngotracheal stenosis are incorrectly diagnosed as having asthma and are treated for presumed lower airway disease. This increases the likelihood of the patient eventually requiring major open surgery in benign disease and can lead to tracheal cancer presenting too late for curative surgery to be performed.
