“…It may be associated with nasopharyngeal stenosis, weak self‐resistance and easy infection of respiratory diseases in young children (Kaya et al., 2017; Masna et al., 2021; Yazici et al., 2014).

In addition, studies (Eftekharian et al., 2012; Elicora et al., 2015; Kwon et al., 2013) have reported that the incidence of OME is the highest at the age of 3–4, with an incidence of 65%, and the lowest at the age of 13–14, with an incidence of 16.67%.…”
