Abstract: Background: Chronic suppurative otitis media (CSOM) is a common cause of hearing loss in developing countries. CSOM is a disease with high prevalence, and if not treated properly, it can lead to various complications that lead to decreased quality of life and death. The incidence of chronic suppurative otitis media in multiple regions in Indonesia is still relatively high. It can be estimated that there are 6.6 million people with CSOM from the 220 million population of Indonesia.
