Se describen 4 pacientes con obstrucción reversible de la vía aérea superior sin causa orgánica identificable cuya forma de presentación, habitualmente con crisis de disnea y ruidos respiratorios, planteó inicialmente dudas diagnósticas con el asma bronquial. Durante los episodios, la curva flujo-volumen mostró una morfología sugestiva de obstrucción de la vía aérea superior con mala reproducibilidad y valores de resistencia repetidamente normales. La fibrobroncoscopia permitió confirmar el carácter funcional de estos casos.

Palabras clave:
Obstrucción funcional laríngea

We describe 4 patients with reversible obstruction of the upper airways, a condition that usually presents with crises of dyspnea and respiratory sounds. No organic cause could be identified and the symptoms were initially confused with those of bronchial asthma. During episodes, the flow-volume curve suggested obstruction of the upper airways with poor reproducibility and repeatedly normal resistance values. Fiberoptic bronchoscopy allowed us to confirm the functional nature of the obstruction in these cases.
