ABSTRACT
Congenital laryngomalacia is the most common disease causing laryngeal stridor in infants. The pathogenesis has not yet been clearly concluded. It may be related to abnormal development of laryngeal cartilage anatomical structure, neuromuscular dysfunction, gastroesophageal and laryngeal reflux disease, etc. The typical manifestations of the disease are inspiratory laryngeal stridor and feeding difficulties, which can be divided into mild, moderate and severe according to the severity of symptoms. The diagnosis is mainly based on clinical symptoms, signs and endoscopy, among which endoscopy is an important diagnostic basis. The treatment of laryngomalacia depends on the severity of symptoms. Mild and some moderate congenital laryngomalacia children can be relieved by conservative treatment, and severe and some moderate congenital laryngomalacia children should be treated by surgery. Supraglottic plasty is the main surgical method, which can effectively improve the symptoms of laryngeal stridor, dyspnea, feeding difficulties and growth retardation in most children, and the surgical effect is good.

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.
