Abstract

--- - Introduction. Dysphonia in children is a common symptom, its prevalence varies between 6% and 23%. There is a broad differential diagnosis and the recommendation is to evaluate dysphonic children with an adequate laryngeal visualization method to achieve an accurate diagnosis and treatment. - Objective. To describe the experience in the diagnosis of dysphonia in children in the voice unit at Universidad Catolica Clinical Hospital Santiago, Chile. - Methods and materials. A retrospective chart review was conducted of all new pediatric patients treated in the voice unit at Universidad Catolica Clinical Hospital between 2012 and 2019. Demographic data, diagnosis, and in-office laryngoscopies were reviewed. All patients were evaluated by the same work team consisting of two Otolaryngologists specialized in vocal pathology and a speech voice therapist. - Results. A total of 126 new pediatric patients between the ages of 0 to 18 years were evaluated in the voice unit at Universidad Catolica Clinical Hospital Santiago, Chile. The majority were males (54%) with an average age of 9 years. 40% of the diagnosis corresponded to vocal nodules, 26% to vocal cord cysts, the remaining to a group of less frequent diagnosis. Two different groups were studied, the first group evaluated during the years 2012-2015 with flexible fibre-optic laryngoscopy and rigid videolaryngostroboscopy (VLS); the second group evaluated between the years 2015-2019 with distal chip flexible videolaryngoscopy, distal chip flexible VLS and rigid VLS. In the second group, the diagnosis of vocal nodules decreased, and the diagnosis of vocal cord cysts increased in comparison to the first group. - Conclusion. Pediatric patients with dysphonia must be evaluated by a multidisciplinary team of experts and adequate equipment. VLS should be considered the gold standard in the diagnosis of vocal cord pathology in pediatric population.
