Abstract:
Objective To investigate the clinical characteristic of 1 000 Hz probe tone tympanometry obtained from neonates who didn’t pass the TEOAE screening . .Methods TEOAE screening were performed to screen the hearing with GSI -70 Automated OAE(Grason-Stadler ,USA) .Then neonates were detected the 1 000 Hz probe tone tympanograms by GSI Tympstar Version Ⅱ Middle Ear Analyzer(Grason-Stadler ,USA) .The relative infor-mation ,including tympanometric peak pressure (Tpp) ,peak admittance(Yp) ,peak compensated static acoustic ad-mittance (Ypc)、tympanometric width(TW) were collatea .The of 1 000 Hz probe tone tympanometry of 47 ears that didn’t pass the first TEOAE and 1 300 ears that passed the first TEOAE were asnpared .Results We found in the single-peak type ,the ratio of the experimental group(59 .57% ) was less than that of the control group(74 .00% ) , and in the flat type the ratio of the the experimental group (23 .40% ) was more than that of the control group (8 . 54% ) ,there was a statistical significance between the two groups in each different type proportion (P<0 .05) .But there is not a statistical significance in the relative values of single -peak type admittance between the two groups , such as tympanometric peak pressure (Tpp)、peak admittance(Yp) etc .Conclusion The majority of 1000Hz tympa-nograms of the neonates who passed TEOAE is the single -peak type ,but the neonates who didn’t pass the first TEOAE mostly shored the flat type The .
