OBJECTIVE To analysis the correlation between the otitis media with effusion and allergic rhinitis in children with adenoidal hypertrophy groups. METHOD Retrospective analysis of cases of adenoidal hypertrophy in children associated with the incidence of otitis media with effusion, with or without allergic rhinitis history, with or without nasal steroid hormone use history information. RESULT In the 287 cases of adenoidal hypertrophy in children cases, does not consider the role of nasal steroid hormones, the incidence of merger cases of allergic rhinitis and otitis media with effusion is 25.56%, compared to the incidence of control group is 32.47%, there is no significant difference (X=1.643, P>0.05). Not use a nasal steroid hormone therapy cases are grouped analysis, the combined incidence of allergic rhinitis group of otitis media with effusion 51.11%, higher than that in the control group to 32. 26% (2=5.019, P<0.05). Merger cases of allergic rhinitis, nasal steroid hormone group OME incidence of 12.50%, significantly below the 51.11% of the OME incidence of nasal steroid therapy group (2=23.32, P<0.01). CONCLUSION In children with adenoidal hypertrophy groups associated with a higher prevalence of otitis media with effusion, allergic rhinitis is an important factor in secretory otitis media. The use of nasal steroid hormones can reduce the incidence of secretory otitis media and may have some effect on the treatment of otitis media. Specific efficacy assessment and treatment mechanism needs further study.
