Abstract

The second most common cause of congenital stridor is vocal fold mobility disorders, which account for 10–20% of congenital laryngeal anomalies. In the article a newborn, in whom congenital vocal fold immobility was diagnosed, is described. The diagnosis was suspected on the basis of the clinical picture, which was typical of vocal cord paralysis. The diagnosis was confirmed by bronchoscopy, using flexible fiberoptic instrumentation. The diagnostic work-up for a clinical picture of congenital stridor and the differential diagnosis are discussed. The purpose of the case description was to present the relatively common, but frequently unidentified cause of congenital stridor, where flexible fiberoptic bronchoscopy is essential for establishing the final diagnosis.

Key words: congenital stridor, unilateral vocal cord paralysis, idiopathic recurrent laryngeal nerve palsy, infants.
