Introduction: Otitis media (OM) refers to an inflammation in the middle ear cleft and is accompanied 
by effusion of fluids into the middle ear due to infection which may be associated with the presence or 
absence of tympanic membrane perforation(1)
. Aim of study: To determine the possible risk factors 
for occurrence of acute suppurative otitis media in preschool children. Patients and methods: The 
study is a descriptive hospital based study, conducted to identify the risk factors of acute suppurative 
otitis media among preschool children in E.N.T out patient clinic at Minia University Hospital during 
the period from February 2018 to July 2018. Results: This study included 502 preschool children 
diagnosed with acute suppurative otitis media (AOM) attending at the out patient clinic of ENT 
department, Minia University Hospital. Their age ranged from one to six years with a mean of 
3.05±1.3 years. Conclusion: 1- There is high incidence of AOM in preschool children so attention 
should be paid for screening and early diagnosis and management of AOM to avoid further 
complications. 2- Incidence of AOM is more in children of rural areas of low socioeconomic classes 
so more health care should be paid to improve hygienic conditions in such areas in order to decrease 
incidence of AOM.
