Wegener Granulomatosis Underlying Fixed Upper Airway Obstruction

Abstract

In an adult female who has been using asthma treatment for years but has not benefited from the treatment, flattening was noted in the inspiratory and expiratory curves of spirometric evaluation. Subsequent examination revealed the presence of subglottic stenosis as the underlying pathology of fixed upper airway obstruction.
