Otitis media can be either acute, less than six weeks, or chronic, which lasts for more than six weeks. Recurrent otitis media refers to three episodes of the disease occurring within six months or four episodes within one year. There are many risk factors for otitis media among children; however, some of such factors may vary based on the type of otitis media. To highlight the risk factors of chronic and recurrent otitis media in pediatrics. Scientific databases were used to search for articles related to our objective. Various terms were used for the search process. The types of articles included in our review were original articles, review articles, meta-analyses, and systematic reviews written in the English language and concerned with our subject. The topic was discussed under four main titles; the first overviewed the prevalence and risk factors of otitis media, the second title discussed chronic otitis media and its risk factors, the third title discussed recurrent otitis media and its risk factors, and the last title discussed the risk factors of both chronic and recurrent otitis media. There are various risk factors for chronic and recurrent otitis media, and they include allergy, passive smoking, male gender, and snoring.
