[Epidemiological survey of dysphonia in school children. Preliminary findings].

In this article the Authors have performed a study on 318 students in Naples to estimate the incidence of the dysphonetic diseases in 6-12-18 years-old subjects. The investigation showed that 34.9% of examined patients revealed speech troubles; these troubles were more common in 6-years-old subjects. The dyslalies were the most common phonetic trouble (97.9%) with prevalence of sygmatism (87.9%). The Authors mean to extend the study on more large sample, although the results of the present study were significant.
