[The role of ultrasonic diagnosis in pediatric laryngology].

In order to have a visual picture of the larynx, laryngeal preparations and larynxes of 50 healthy children were exposed to ultrasonic scanning. Also, 48 children, aged 9 months to 15 years, were examined 77 times: their complaints were dysphonia and/or impaired breathing. On the basis of the findings sonographic signs of laryngeal papillomatosis were described (18 children). Ultrasonic observations were in the norm in catarrhal laryngitis (10 children) and limited forms of hyperplastic laryngitis (18 children). Ultrasonic examination helped diagnose impaired mobility of vocal cords. It is recommended to use ultrasonic visualization for rapid diagnosis of ENT diseases in children as well as for surveillance of children with laryngeal papillomatosis.
