Epidemiology of middle ear effusion and tubal dysfunction. A one-year prospective study comprising monthly tympanometry in 387 non-selected 7-year-old children

Otitis Media in Greenland: studies on historical, epidemiological, microbiological, and immunological aspects

“…The study confirmed the high prevalence rate s of especially SOM and COM including CSOM compared with prevalence studies from Denmark and Sweden (Lous and Fiellau-Nikolajsen 1981, lngvarsson et al 1982, Fiellau-Nikolajsen 1983, Tos 1983, Birch et al 1984). The present survey did not use otomicroscopy, and took place in two relatively short and different time periods at two different localities.…”

Otitis Media and Speech-in-Noise Recognition in School-Aged Children

“…Firstly, in the first 2 years the children were seen every 3 months. It is possible that incidents of OM could have occurred between the 3-monthly visits and remained undetected, as the duration of an OM incident is generally less than 1 month [Lous and Fiellau-Nikolajsen, 1981;Casselbrant et al, 1985]. In the same way, it cannot be assumed that children with some OM-positive results in a row had no OM-free periods in between.…”

Prevalence of Hearing Loss among First Grade School Children in Tirana,Albania – A Repeated Cross-Sectional Survey

“…A study found that 1 in 4 school children aged 7 years had some degree of Otitis Media with Effusion [23]. However, routine screening for OME is not recommended because the evidence of more benefits from early detection is lacking [24]. The low prevalence of Otitis Media with Effusion in our study and other studies is due to the different aims of each study: we aimed to detect the hearing impairment and selected only children who showed such signs on tonal audiometry whereas other studies physically examined all children for signs of Otitis Media with Effusion and thus reported much higher prevalence [23].…”
