Idiopathic subglotic stenosis (ISS) is a rare progressive condition affecting young females. The cause is unknown and in some reports relation with anti-cytoplasmic antibodies (ANCA) and gastroesophageal reflux disease (GERD) has been reported. Surgical resection of stenotic area or dilatation with laser ablation are the main treatment options. We report a case of ISS in a five-month pregnant woman with gradual deterioration who was treated with dilatation by rigid bronchoscopy and laser ablation of excessive tissue.
