External laryngeal injuries in children--comparison of diagnostic methods.
OBJECTIVE
The injuries of the larynx constitute around 1% of all injuries. The great majority of the injuries of the larynx happens during playing. The effects of these injuries may appear insignificant however, not always the direct clinical symptoms correlate with the degree of respiratory tract failure. The symptoms of laryngeal injuries depend on the extension and strength of the trauma and always relate to impair patency of respiratory tract. The aim of the study is to compare two diagnostic methods: laryngoscopy and ultrasonography in evaluation of laryngeal injuries in children.


METHODS
In the Department of Pediatric Otolaryngology, Medical University of Warsaw, in the period between 2004 and 2010 there were hospitalised 15 children with external injury of the larynx.


RESULTS
From among 15 hospitalized children, 7 were qualified as not serious trauma and were treated preservatively and the other 8 as sever trauma. The mechanism of traumas was diverse. Dyspnea was a predominating symptom, the others included hoarsness, change in voice quality, even aphonia, pain while speaking and swallowing, cough and hemoptysis.


CONCLUSIONS
Direct laryngoscopy is a standard in diagnostics of the injuries of the larynx. Ultrasonography of the larynx is recommended in every case of laryngeal injury as an additional non-invasive complementary diagnostic examination.
