Tympanometry in Two-Year-Old Children

Abstract: Tympanometry was repeated 3, months after the first evaluation of 254 healthy 2-year-old children. Although the total distribution of tympanogram types was the same at the second as at the primary evaluation, 14% of the ears showing type B indicating middle ear effusion, and 38.6% having a negative middle ear pressure of – 100 mmH2O or less, the types altered in 51.8% of all ears. Type B had improved in 5 3% of the ears in which it was originally found, indicating a considerable tendency to spontane… Show more

“…She found no difference between family day-care and home care, although her study was carried out during the winter when the difference between these two groups of the present material was most marked (table IV). Tos et al (1978a) demonstrated that 2-year-old children in public nursery showed significantly poorer results in tympanometric screening during the months November and December and that children in family day-care had a higher prevalence of abnormal tympanograms than children cared for in their own homes. Thus, our Finding of the highest prevalence of secretory otitis and tubal dysfunction in 3-year old day-care centre children was not unexpected.…”

“…Recent research has disclosed an extremely high frequency of middle ear effusions among otherwise healthy 2-and 3-year-olds (Fiellau-Nikolajsen et al, 1977;Tos et al, 1978a) throughout the year (Fiellau-Nikolajsen, 1978). How ever, the practical implications of these findings have not yet been elucidated, and prior to systematic tracing or prophylactic efforts, the epidemiological aspects have to be clarified in detail.…”

“…The economic factor did not appear to be important in studies carried out in Denmark [9] and in Israel, where the incidence of otitis was compared for ethnic groups of widely differing socio-economic levels [10], al though in the Caribbean countries a correla tion between income per capita and otitis has been observed [11].…”

“…Esses resultados concordam com os de vários outros trabalhos [17][18][19][20][21][22][23][24][25][26][27][28][29][30] . As pesquisas de Fiellau-Nikolajsen mostraram que a remissão espontânea da OMCS é menos provável quando não ocorrer dentro dos primeiros três meses de instalação da doença; passado este período, poderia ser necessária alguma intervenção.…”
