Endoscopic and ultrasonographic evaluation of external laryngeal injuries in children
Journal Title: New Medicine - Year 2012, Vol 16, Issue 4
Abstract
<b>Aim.</b> The aim of the research is to evaluate the possibilities of diagnosing laryngeal injuries with the use of laryngoscopy and ultrasonographic examination.<br><b>Material and methods.</b> There were diagnosed and treated 15 children aged 5-14 (6 girls and 9 boys) with external injuries of the larynx. In all cases laryngoscopy under general anesthesia and radiological examinations including ultrasound of the larynx, X-ray of the cervical spine and in selected cases CT of the chest and neck were performed.<br><b>Results.</b> In the studied group of 15 children we observed: hit of neck into a blunt object in 10 children, strangulation with a rope or a scarf in 2 children, transport trauma in 2 children and kick in the neck in 1 child. In ultrasonographic examination the following disorders were revealed: unilateral paralysis of vocal folds (7 children), bilateral paralysis of vocal folds (1 child) and asymmetry of vocal fold movement (1 child). In laryngoscopy immobilization of one vocal fold in 7 children, adhesions in the area of the posterior commissure in 3 children and partial adhesion of vocal folds in one child were confirmed. Incorrect, asymmetrical unilateral adjustment of aryepiglottic folds was observed in ultrasound examination and laryngoscopy in 7 children.<br><b>Conclusions.</b> Direct laryngoscopy is a standard in diagnostics of injuries of the larynx. Ultrasonography of the larynx is recommended in every case of laryngeal injury as an additional, non-invasive, complementary diagnostic examination. Ultrasonography in comparison with laryngoscopy under general anesthesia more precisely evaluates mobility of vocal folds and diagnoses fractures of cartilages without dislocation.
