Dysphonia in children.

INTRODUCTION

Vocal symptoms are common among the pediatric population and are often caused by vocal abuse. Laryngoscopy is essential for their diagnosis because it helps differentiate several laryngeal lesions, leading to a decision for suitable treatments considering each case.

OBJECTIVES

This study aims to present the clinical characteristics, and the laryngoscopic diagnosis of a dysphonic child population.

METHODS

The parents of 304 children, aged from 4 to 18 years and presenting prolonged hoarseness, answered a questionnaire about their children's voice, and all children were subjected to videolaryngostroboscopy.

RESULTS

Male children aged from 7 to 12 years (64%) were predominant. Vocal abuse (n-162) and nasal obstruction symptoms (n-10) were the most frequent associated symptoms. The vocal symptoms had a chronic evolution (over 1 year) and were reported by most parents (n-200). The most commonly diagnosed lesions in the laryngoscopic exams were vocal nodules (n-175) and epidermal cysts (n-47). Furthermore, there was an association of some lesions, especially minor structural alterations.

CONCLUSION

In the present study, dysphonia occurred mainly in children aged from 7 to 12 years, predominantly males. Vocal abuse and nasal obstruction symptoms were frequently reported. Vocal nodules and cysts were the most commonly diagnosed laryngeal lesions in the laryngoscopic exams.
