  • Abstract
  • Look Inside

Upper airway obstruction is an important, often unrecognized cause of dyspnea, even in patients with normal spirogram. Conventional lung function tests may not fully disclose the extent of the tracheal stenosis.

In the present work, 3 cases of tracheal stenosis were studied by tracheotomograms, conventional spirometry and flow-volume curves before and after operation.

Case 1. A 28-year-old male complained of dyspnea, wheezing and hemoptysis. The tomograms of trachea demonstrated a density in the cervico-mediastinal trachea.
