Diagnostic possibilities of ultrasound scanning and color doppler of larynx in children with dysphonia

[Pediatrics]
Maria Vladimirovna Subbotina; Tatiana Dmitrievna Prikhodko;

The aim of the work was to determine the diagnostic possibilities of B-mode ultrasound scanning (USS) and color Doppler imaging (CDI) of the larynx in 60 patients with dysphonia and 20 healthy children aged from 1 to 14 years by Sonoscape, Logiq 7 and Aloka 1100 scanners with 7–15 MHz transducers. The diagnosis was verified by laryngoscopy.

According to USS, the scar membrane in the anterior commissure and laryngeal papillomas were visualized as echogenic formations, and unilateral paralysis was determined by the absence of displacement of one half of the larynx. Nodules of the vocal folds in the form of symmetric echogenic formations were detected with USS only in 14% of children with pathology; with functional dysphonia, the ultrasound picture corresponded to the norm. In the CDI mode, better visualization of papillomas, membranes, lack of closure of folds during phonation was noted, and the paralyzed fold was stained somewhat weaker.
