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.

Objective. To study the prevalence of associated airway anomalies in infants presenting with moderate to severe laryngomalacia. Methods. Eighty three symptomatic infants with recurrent respiratory symptoms including wheeze and cough diagnosed as moderate to severe laryngomalacia based on their clinical and direct laryngoscopic findings were subjected to fiberoptic bronchoscopy (FOB) during the period March 2007 to February 2009 in the Department of Pulmonology, Institute of Child Health and Hospital for Children, Chennai, India. Analysis of the clinical features, radiological findings and associated lower airway anomalies by FOB was done. Results. Lower airway anomalies were demonstrated in 40 (48%) infants of the study population. Tracheomalacia was the most common lower airway anomaly 24(29%) followed by bronchomalacia 8(10%) and tracheobronchomalacia 6 (7%). (4:1:1). Conclusion. Infants with moderate and severe laryngomalacia should be evaluated with flexible fibreoptic bronchoscopy to rule out associated lower airway lesions.

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.
