Parental smoking and persistent otitis media with effusion in children

A total of 163 children were entered into a case-control study to determine whether any causal relationship exists between otitis media with effusion (OME) requiring grommet insertion and parental smoking. One hundred children with persistent OME formed the case group and 63 children with normal ears formed the control group. The prevalence of parental smoking in each group was then compared. Information was collected by questionnaire and further details about the subjects with regard to surgery of the upper respiratory tract were also gathered. Analysis of findings in this study and previous reports has failed to demonstrate a significantly increased prevalence of smoking in at least one parent, amongst children with persistent otitis media with effusion requiring surgical intervention.
