Short answer · Medically reviewed summary · Last updated: 2026-05-08
Idiopathic Subglottic Stenosis (ISS) is a rare, localized narrowing of the airway just below the vocal cords with no known underlying cause, often referred to in older literature as idiopathic laryngotracheal stenosis. While clinical terms vary, medical professionals currently prefer the term Idiopathic Subglottic Stenosis to distinguish it from stenosis caused by intubation, trauma, or systemic inflammatory diseases. What are the common synonyms and historical names for Idiopathic Subglottic Stenosis? Because Idiopathic Subglottic Stenosis is a diagnosis of exclusion, its nomenclature has evolved as our understanding of airway pathology has refined.

Idiopathic Subglottic Stenosis (ISS) is a rare, localized narrowing of the airway just below the vocal cords with no known underlying cause, often referred to in older literature as idiopathic laryngotracheal stenosis. While clinical terms vary, medical professionals currently prefer the term Idiopathic Subglottic Stenosis to distinguish it from stenosis caused by intubation, trauma, or systemic inflammatory diseases.
What are the common synonyms and historical names for Idiopathic Subglottic Stenosis?
Because Idiopathic Subglottic Stenosis is a diagnosis of exclusion, its nomenclature has evolved as our understanding of airway pathology has refined. Historical terms often focused on the anatomical location rather than the etiology. You may encounter the following terms in older medical records or international literature:
- Idiopathic laryngotracheal stenosis
- Idiopathic tracheal stenosis
- Primary subglottic stenosis
- Subglottic cicatricial stenosis
How is Idiopathic Subglottic Stenosis classified in medical systems?
Standardized medical coding helps researchers and clinicians track the prevalence of Idiopathic Subglottic Stenosis. Official classifications include:
- Orphanet: ORPHA:166060 (Idiopathic subglottic stenosis)
- ICD-10: J38.6 (Stenosis of larynx)
- ICD-11: CA02.1 (Subglottic stenosis)
Why does this condition have multiple names?
The naming of Idiopathic Subglottic Stenosis has shifted due to advancements in diagnostic imaging and the need to differentiate it from secondary causes. Historically, many cases were grouped under general "laryngeal stenosis." As clinicians recognized that Idiopathic Subglottic Stenosis predominantly affects healthy, middle-aged women—with a strong female-to-male ratio often cited as 9:1—the term "idiopathic" became vital to separate it from post-intubation injury. Using the precise current terminology helps ensure your medical records accurately reflect that the condition arose without a clear external trigger.
Next steps
- Consult an otolaryngologist or a laryngologist who specializes in airway reconstruction.
- Request that your medical records specify Idiopathic Subglottic Stenosis to avoid confusion with traumatic airway injury.
- Connect with the 3 members of the DiseaseMaps.org community who are navigating this diagnosis to share experiences.
- Monitor for symptoms such as dyspnea (shortness of breath) or stridor, and report them to your specialist immediately.
