Aetiology of airway stenosis according to age distribution and clinical features.

Sites	Age group	Number of cases	Clinical features leading to diagnosis

Blunt trauma	P	1	Failed decannulation
Glottis
Congenital	P	1	Stridor since birth
Acute laryngitis	P	1	Progressive shortness of breath with change in voice
Interstitial lung disease with IgA deficiency	P	1	Repeated failures of extubation
Following excision of RRP	P	1	Progressive shortness of breath with change in voice
Subglottis
Prolonged intubation	P; A	3; 5	Failed extubation/failed decannulation of the tracheostomy tube
Congenital	P	1	Stridor since birth
Idiopathic	A	1	Progressive respiratory distress with no obvious cause
Trachea
Prolonged intubation	A	16	Failed extubation/failed decannulation of the tracheostomy tube
