Abstract

TANDI, Ruth Isaura et al. Prevalence of the disease and sociodemographical and clinical characteristics of the chronic media otitis in the Clinics Hospital. An. Fac. Cienc. Méd. (Asunción) [online]. 2020, vol.53, n.2, pp.59-66. ISSN 1816-8949.  https://doi.org/10.18004/anales/2020.053.02.59.

Chronic otitis media is a chronic inflammation of the mucoendostium of the middle ear and annexes, with or without perforation of the eardrum, with or without exudate. According to data obtained by the World Health Organization after the analysis of published research papers, the prevalence for South America and Central America is around 1.5%. Paraguay does not have a study similar to this one that has been published. For this reason, we set out to determine the burden of the disease and the sociodemographic and clinical characteristics of patients with chronic otitis media operated at the Hospital of Clinics in the period 2015-2019. An observational, descriptive, cross-sectional, retrospective study was conducted. Of 41885 patients operated 9.42% were patients of the Chair and Department of Otolaryngology and of these, 274 had chronic otitis media, which represents 6.94% of the total of patients operated by the Chair and Department of Otolaryngology and 0,65% of the total of patients operated in the Hospital in the mentioned period of time. We could conclude that chronic otitis media is a pathology of high prevalence for the otolaryngology service of the Hospital of Clinics, however, it represents a low burden for total hospital administration.
