PURPOSE: to compare the otorhinolaryngologic diagnosis of vocal folds edge lesions and their Maximum Phonation Times in adults and children of both genders; to check the frequency of the Maximum Phonation Times types (reduced, normal or increased) in the pathologies of vocal folds edge and the frequency of these pathologies in individuals with mature vocal fold edge (adults) and immature vocal fold edge (children) in both genders. METHODS: to recover the database of the patients that have complained about voice. They have been attended in a phonological university service office, with a medical diagnosis of the edge pathology of vocal fold. Among the 152 records displayed by the database, 54 have been passed for the inclusion criteria, being 8 cases from cysts of vocal fold and 46 from vocal fold nodules. RESULTS: the vocal fold nodules have showed the lesions with more frequency in adults and children, with higher portion in adult women and male gender children. The cysts of vocal folds have occurred in a higher portion in female gender both in children as well as in adults. There was a decrease in Maximum Phonation Times of children of both gender and of adults women. CONCLUSION: as the vocal fold edge lesions difficult the appropriate glottal closing, they tend to cause a decrease in the Maximum Phonation Times values.
