Abstract
Background: Stridor is a harsh, vibratory sound with variable pitch
which is caused by partial obstruction of airway that results in
turbulent airflow. It is mainly due to anatomic deformities in the
infantile age group. However, various acquired conditions affecting
upper airway may also cause stridor. Here, we evaluated 87 cases of
stridor using Flexible bronchoscope in order to determine the cause of
stridor. Objective: To determine the clinical characteristics, Flexible
bronchoscopy findings and clinical correlation in children admitted in
our hospital with complains of stridor. Design: Retrospective
observational study. Setting: Single center study conducted in Amrut
medical foundation. 87 children aged less than 5 years with a clinical
complains of stridor were included in the study and Flexible
bronchoscopy was performed. The findings were analyzed and results were
reported. Results: A total of 87 children with stridor were enrolled in
the study and Flexible Bronchoscopy was performed in them. Of these, 68
children had an abnormal bronchoscopy finding. Laryngomalacia was the
commonest cause of stridor observed followed by subglottic stenosis and
tracheomalacia. Cough was the commonest presenting symptom associated
with stridor and tachypnea was the commonest clinical sign observed in
these children. Conclusion: Flexible bronchoscopy plays an important
role in diagnosing the exact cause of stridor in pediatric age group.
