Abstract:
Objective To study the reference values and related factors of tympanometry for children between 2 and 15 year-old .Methods From December 2014 to March 2015 ,a total of 120 children (240 ears total) among 2 to 15 year-old (6 .95-3 .12) with Type A tympanograms received the singe -frequency component tympanometry test ,including acoustic equivalent volume (Vea ) ,peak-compensated static admittance (Ytm ) ,tympanometric peak pressure (TPP) and tympanometric gradient (TG) .With the results of each test ,the relationships were conducted according to the differences of age and gender .The outcomes also were compared with the recent studies abroad .Re-sults The difference of TPP was statistically significant among the gender group ,and the differences of Vea and TPP were statistically significant between different age groups ,2-6 year pre-school children and 7~15 yr school children .Conclusion The normative values of each tests were significantly different between Chinese and western children of 2-15 years .We would speculate that the differences of TPP in the age and gender group have changed with the physiological characteristics of Eustachian tubes and eardrums and the differences among male and female .
