  • Abstract
  • Look Inside

 The purpose of this investigation is to measure the airway ventilation in patients with laryngeal stenosis by using a new apparatus for ventilatory function measurements, and to note whether or not any characteristic changes could be found in various other pathologies causing laryngeal stenosis.

 The study was made on four separate groups; group of normal subjects for control; laryngealstenosis group; laryngeal polyposis group and laryngeal paralysis.

 The measurements consisted of respiratory resistance, spirometric values. flow-volume curve and closing volume.

 The laryngeal stenosis group showed through the time dependent parameters significantly different picture from that of the control subjects.

 No significant change was noted in cases with laryngeal polys.

 In cases with recurrent paralysis obstruction impairements of the small airways were noted.
