Abstract：Objective Analises of tympanometry and otoacoustic emissions results in preschool children with adenoid hypertrophy. Methods Acoustic immittance and otoacoustic emissions results and parameters were collected in 75 preschool children (aged 3-7 years) with varying degrees of adenoidal hypertrophy. Results The rates of type A immitance curve and positive acoustic reflex and average peak ear canal pressure in children with degree III adenoid hypertrophy were all lower between those with degree I or II adenoid hypertrophy (p<0.05). The rate of positive DPOAEs in children with degree III adenoid hypertrophy were also lower than those with degree I (1–8 kHz) or II (1.5-8 kHz) hypertrophy (p<0.05). In chil-dren with type A tympanograms, the rate of positive DPOAEs (0.5 – 2 kHz) in those with no acoustic reflex was lower than those with positive acoustic reflex (p <0.05). Conclusion Preschool children with adenoidal hypertrophy should re-ceive routine acoustic impedance and/or otoacoustic emission tests for early diagnosis of secretory otitis media in this popu-lation. The level of hypertrophy adenoidal can affect middle ear functions in these children, with higher levels of adenoid hy-pertrophy more likely to cause secretory otitis media of greater severities.
