摘要：Purpose: to describe the audiological characteristics of patients with mucopolysaccharidosis. Methods: after formulating the research question, three databases were considered for the search (Science Direct, Virtual Health Library and Web of Science); the following descriptors were used: mucopolysaccharidoses, hearing loss, and audiology. Articles were included that were original and complete, presenting audiological evaluation data in patients with mucopolysaccharidosis. Each study was classified according to the degree of recommendation and the level of scientific evidence, based on the criteria established by the Oxford Center for Evidence-based Medicine, and the results obtained from the evaluations were analyzed. Results: of the 499 articles found, eight met the inclusion criteria. Pure tone audiometry and tympanometry were performed in all studies. The incidence of hearing loss in patients with MPS ranged from 54% to 100% of the cases, with conductive hearing loss corresponding to 30% and 58.33%, mixed hearing loss corresponding to 28.5% and 66.66% and sensorineural hearing loss corresponding to less than 14%. None of the studies described the responses of otoacoustic emissions and auditory evoked potentials. Conclusion: the prevalence of hearing loss among individuals with MPS is higher than 54% of the cases, of which conductive and mixed are predominant.
