ABSTRACT
Toda obstrucción de la vía aérea se expresa por un estridor que será diferente según la localización de la obstrucción. El estridor es un ruido ocasionado por el pasaje de aire en forma turbulenta a través de una vía aérea con calibre disminuido. Cuando la obstrucción se ubica por encima de las cuerdas vocales el estridor será inspiratorio. Describimos diferentes patologías de la laringe supraglótica, congénitas y adquiridas, que presentan estridor en algún momento de su evolución.
An obstructed airway causes stridor. Stridor willbe different depending on the location of the obstruction. Stridor is a noise caused by the passage ofturbulent air through a diminished airway caliber. If the obstruction occurs above the vocal cords, itwill be inspiratory. We describe different pathologies of the supraglotticlarynx, both congenital and acquired, producingstridor at some moment of their evolution.

Stridor in the pediatric age group needs detailed evaluation. Laryngomalacia, the commonest cause of stridor is mostly benign, but in about 10% patients can be an important cause of morbidity and mortality. Laser surgical correction in patients with severe laryngomalacia gives good results. We evaluated 32 patients of stridor. All were screened with fibreoptic laryngoscopy and whenever indicated, direct endoscopy was carried out. 13 (40%) of the patients had laryngomalacia. Of these, 8 had severe laryngomalacia and underwent treatment with diode laser. All of them showed definite post procedure improvement.
