Background. Evidence-based information on genetic sensorineural hearing loss in Latin America is limited, hindering the advancement of related clinical practice and the development of relevant healthcare policies in the field. This study describes sociodemographic and clinical characteristics of a group of Chilean participants with congenital, childhood, progressive or late-onset sensorineural hearing loss of unknown etiology; all non-genetic causes of hearing loss were excluded. Methods. A quantitative study, with a non-experimental, observational, cross-sectional design and a descriptive scope. From 978 patients diagnosed with SNHL, 286 subjects fulfilled the inclusion criteria, and 138 patients accepted to participate. Results. The most frequent audiological-profile was symmetrical-bilateral-profound-SNHL with a sloping pattern. The median age at audiological diagnosis was 24.5 months (IQR:12-53) and at first-time Hearing-Assistive-Device-use (HAD-use) was 30 months (IQR:13-69). 71% of HAD were financed by public resources. Conclusion. The age at audiological diagnosis in SNHL of suspected genetic causes is still far from international standards. These results are valuable for public health research and policy development, not only for the Chilean population, but also for other Hispanic communities and other middle-high income countries.
