Figure 1

Investigations during the period of mistaken diagnosis. Spirometry and flow-volume loops taken over a ten-year period from initial presentation through to emergency laser resection of the patient’s stenosis. The inset image is that of the patient’s larynx via an endoscope at the time of her first surgery and shows a Myer-Cotton grade 2 (51–70%) mature fibrotic subglottic stenosis.
