【摘要】：目的探讨A型鼓室导抗图儿童单频率单成份鼓室图正常值范围及影响因素。方法 2014年12月至2015年3月对符合Jerger分类法中A型鼓室导抗图的120例(240耳)2~15岁儿童进行单频率单成分鼓室图测试(Y_(-226)),获取外耳道等效容积(acoustic equivalent volume,V_(ea))、峰补偿静态声导纳(peak-compensated static admittance,Y_(tm))、峰值处鼓室压(tympanometric peak pressure,TPP)和鼓室图梯度(tympanometric gradient,TG)等,比较不同年龄、性别间的差异。结果本组对象中,男性和女性TPP值分别为-32.35±22.40和-35.38±18.70daPa,差异有统计学意义(P0.05);2~6岁组和7~15岁组V_(ea)值分别为0.79±0.13和0.90±0.19ml,TPP值分别为-40.78±23.83和-30.21±18.80daPa,组间差异均有显著性意义(均为P0.05),其余指标差异均无统计学意义。结论本组2~15岁A型鼓室图儿童单频率单成分鼓室图在2~6岁、7~15岁组间及不同性别组间峰值处鼓室压有差异;7~15岁组外耳道容积大于2~6岁组;可能与外耳道骨部及软骨部随着年龄增长而自然发育有关。
[Abstract]:Objective to investigate the normal range of single frequency single component tympanogram in children with type A tympanogram and its influencing factors. Methods from December 2014 to March 2015, a single frequency single component tympanogram test (Y _ (- 226),) was performed in 120 children (240 ears) 2 years old with type A tympanogram according to the Jerger classification. The equivalent volume of external auditory meatus was obtained by Y _ (- 226) Tympanogram. V_ (ea), peak compensated static admittance (tympanometric peak pressure,TPP) and tympanogram gradient (tympanometric gradient,TG) at the peak of peak-compensated static admittance,Y_ (tm), compared the difference between different age and sex. Results the TPP values of male and female were-32.35 卤22.40 and-35.38 卤18.70 da Pa, respectively, the difference was statistically significant (P0.05). 2in the 6-year-old group and the 7-year-old group, the V _ (ea) values were 0.79 卤0.13 and 0.90 卤0.19 ml respectively, and the TPP values were-40.78 卤23.83 and-30.21 卤18.80 da Pa, respectively. There was significant difference between the two groups (P 0.05). There was no significant difference in other indexes. Conclusion the single frequency and single component tympanogram of children with type A tympanogram of 2 ~ 15 years old have difference in the peak tympanic pressure between 2 ~ 6 years old, 7 ~ 15 years old and different sex groups, the volume of external auditory canal in 7 ~ 15 _ year-old group is greater than 2 ~ 6 years old group, and the volume of external auditory canal is more than 2 ~ 6 years old group. It may be related to the natural development of the osseous part and cartilage part of the external auditory meatus with age.
