Abstract
Laryngomalacia is the most frequent congenital abnormality of the larynx, accounting for approximately 60-75% of congenital stridor cases. Despite its benign and self-limited aspects, 10% of cases require intervention. Currently, supraglottoplasty is considered the standard treatment of severe laryngomalacia. ObjectiveTo describe the experience of the authors in the surgical treatment of patients with severe laryngomalacia. Methodology: A retrospective study. MethodThe medical records of 11 consecutive cases of severe laryngomalacia who underwent surgical treatment between 2003 and 2012 were analyzed for age, gender, symptoms, associated diseases, surgical technique employed, extubation time, surgical complications, length of hospital stay and clinical outcome. ResultsOf the 11 cases of severe laryngomalacia, six patients (54.5%) were operated with the use of CO2 laser and five patients (45.5%) were submitted to the cold technique. Only 1 patient (9.1%) required surgical reintervention. There were no cases of surgical complications. All patients had clinical improvement. ConclusionSupraglottoplasty proved to be effective and safe in the treatment of severe laryngomalacia.

Summary
Laryngomalacia is the most common congenital abnormality of the larynx, accounting for about 60% to 75% of congenital stridor cases[1,2,3]. Its pathogenesis is not fully understood, there is a collapse of supraglottic tissues during inspiration[4,5], generating a high-frequency inspiratory stridor, exacerbated in the supine position during feeding, agitation and crying[6,7,8]. This stridor usually appears in the first two weeks of life, with an incidence peak around 6 months and spontaneous resolution in 90% of the cases by the second year of life[9,10]. Some authors advocate hyomandibulopexy as a treatment for severe laryngomalacia, most operations currently involve endoscopic procedures in the supraglottic region, the so-called supraglottoplasties[11,12,13]
