Is subglottic stenosis a respiratory disease?
Subglottic stenosis comes in two forms: acquired and congenital. Endoscopic view of congenital subglottic stenosis. Acquired subglottic stenosis often occurs after long periods of intubation and ventilation for respiratory problems.
What causes glottic stenosis?
Glottic stenosis is narrowing of the larynx at the level of the glottis (ie, vocal cords). It is caused by webbing, fibrosis, or scarring and most often involves the posterior glottis. The most common cause of stenosis is prolonged endotracheal intubation.
Is subglottic stenosis life-threatening?
The condition affects both soft tissue and cartilage support in the region. Subglottic stenosis is either a congenital disorder or a medical condition that develops later in life. Although subglottic stenosis is relatively rare, it can be life-threatening and requires immediate medical attention.
What are the symptoms of subglottic stenosis?
People with subglottic stenosis may experience a few different symptoms, including:
- Shortness of breath (dyspnea).
- Stridor (a high-pitched wheezing sound when breathing in).
- Hoarseness.
- Voice changes.
- Increased mucous production.
- A cough that doesn’t go away.
Can subglottic stenosis be cured?
To date single-staged laryngotracheal resection with primary end-to-end anastomosis has proved to offer the best option of cure for benign subglottic stenosis allowing definitive and stable high success rate.
Does subglottic stenosis go away?
Yes, sometimes. Mild cases of subglottic stenosis can potentially go away without treatment. That’s why close monitoring is often recommended in these instances.
What does subglottic stenosis feel like?
Subglottic stenosis is characterized by the narrowing of your subglottis (a portion of your windpipe). The condition affects females almost exclusively and causes hoarseness, wheezing and shortness of breath.
How do you fix subglottic stenosis?
Several different surgical procedures have been used to treat idiopathic subglottic stenosis, but are generally categorized into: 1) endoscopic dilation of the tracheal stenosis (accomplished with rigid instruments or inflatable balloons); 2) endoscopic resection of the stenosis (with prolonged medical therapy after …
What is the role of eosinophilia in the diagnosis of asthma?
Eosinophilia and elevated serum IgE levels may help guide therapy in some cases. Arterial blood gases and pulse oximetry are valuable for assessing severity of exacerbations and following response to treatment. Blood eosinophilia greater than 4% or 300-400/μL supports the diagnosis of asthma, but an absence of this finding is not exclusionary.
How is asthma treated with theophylline?
Treatment with proton pump inhibitors, antacids, or H2 blockers may improve asthma symptoms or unexplained chronic cough. The treatment of asthma with agents such as theophylline may lower esophageal sphincter tone and induce GERD symptoms. Some people with asthma have significant gastroesophageal reflux without esophageal symptoms.
Which imaging studies are performed in the workup of asthma?
The chest radiograph remains the initial imaging evaluation in most individuals with symptoms of asthma, but in most patients with asthma, chest radiography findings are normal or may indicate hyperinflation. Exercise spirometry is the standard method for assessing patients with exercise-induced bronchoconstriction. See Workup for more detail.
