Abstract

Stridor is a considerable finding, which arises from congenital or acquired causes, that might have a good prognosis or might be a life-threatening cause, and hence requires rapid assessment and intervention. Stridor is mostly considered as croup in pediatric emergency units. A multidisciplinary approach might be required for an accurate diagnosis. The patient’s age, time and severity of initial symptoms, response to treatment, and coexistent findings assist in differential diagnosis. Detecting the underlying cause may be difficult and time consuming. In this study, we intended to present cases that we assessed regarding the etiological reasons presented with chronic stridor and to present remarkable characteristics of them in diagnosis and differential diagnosis, by considering the literature. Patients diagnosed with subglottic stenosis, subglottic hemangioma, laryngomalacia and laryngeal web were presented with distinctive history and clinical findings. Patients with intermittent respiratory problems coexisting with stridor can be diagnosed typically through an adequate medical history, a well-enough physical examination, and radiological methods. Flexible endoscopy provides a safe and complete examination of the children’s airway.
