ABSTRACT

Introduction: dysphonia is present in 6 % to 23 % of children between 4-12 years of age and its study suppose a diagnostic and therapeutic challenge because the procedures currently used require a complete collaboration from the patient. In Colombia, a study on the characterization of the main pathologies that cause dysphonia in children has not been carried out so far. The findings are like those reported in the world literature, however, vocal nodules are not the main cause of dysphonia in children in our population as reported so far. The objective of this study is to report our stroboscopic findings in children with chronic dysphonia (more than 4 weeks) that attend to the laryngology service of the San Ignacio University Hospital, in Bogotá, Colombia, and compare them with the international literature. Materials and methods: A retrospective descriptive study was conducted. Medical records and stroboscopies of patients younger than 18 years with chronical voice symptoms (greater than 4 weeks), that assisted to a laryngology consultation at the San Ignacio University Hospital, in Bogotá, Colombia within the last 10 years were analyzed. A descriptive statistical analysis was performed. Results: 141 patients were selected, 73 % had bilateral vocal fold lesions, 9.9 % unilateral lesions and 16.3 % had primary muscle tension dysphonia. Most of the lesions were acquired, with a slight predominance of lesion on the left vocal fold and in males. The most common finding was vocal sulcus (13.37 %), followed by muscle tension dysphonia and vocal nodules (13.2 %). A 41.06 % of patients referred vocal abuse, and within this group, vocal nodules where most prevalent. Discussion: there was a predominance of vocal sulcus, this differs from the literature in which vocal nodules are the most frequent finding. In this study, vocal nodules where related to chronic voice abuse, which was referred by half of the patients. A relation between muscle tension dysphonia and singing was also observed, an important number of patients referred gastroesophageal reflux symptoms as well. Conclusions: this is the first study in Colombia and the second one in Latin America of its kind. The results are generally consistent with the literature, but the first cause of dysphonia in our study is vocal sulcus, as opposed to vocal nodules which are typically the most common cause. There was a relation between chronic voice abuse, vocal nodules and cysts, this supports the theory that cysts are acquired lesions and not congenital.
