Abstract
OBJECTIVE To compare the differences in wideband absorbance and the resonance frequency (RF) between patients with inner ear malformations and normal control, and to explore the auditory diagnostic value of wideband acoustic immittance (WAI). METHODS A total of 38 patients (59 ears) with enlarged vestibular aqueduct (EVA), 13 patients (14 ears) with incomplete partition type I (IP-I) and 13 patients (26 ears) with incomplete partition type II (IP-II) were included. 50 normal control (100 ears). All subjects underwent WAI tests to compare the absorbance configuration and resonance frequency. RESULTS All the group showed lower absorbance at ambient pressure than at peak pressure in certain frequencies under 2000Hz. Under 1000Hz, the absorbance of EVA was higher than that of other groups. The average absorbance and highest absorbance of IP-I were the lowest(P<0.05). However, IP-II and normal group had similarity on some characteristics. The three IEM groups mainly different at low and high frequencies, but not at medium frequencies. The highest absorbance of all the groups were appeared around 3000Hz. The RF of all the groups from low to high were EVA<IP-II<normal control<IP-I, and the lowest was EVA(P<0.05). CONCLUSION Inner ear malformations can affect energy absorbance and RF. WAI is sensitive and non-invasive to provide useful information about inner ear status and facilitate detection of ear pathology.

Abstract
PURPOSE U.S. national wideband absorbance (WBA) data for 17,446 ears included in the National Health and Nutrition Examination Surveys for 2015-2016 and 2017-2020 were analyzed to develop and apply normative reference intervals (RIs). METHOD Analyses used distribution-free medians and cumulative distribution functions (CDFs). Notable differences between medians were defined as those with non-overlapping 95% confidence intervals, and differences between CDFs were evaluated using Cohen's h effect size. Strict inclusion criteria identified "healthy ears" with 1,240 ears meeting all the inclusion criteria for the reference group. RIs, WBA values corresponding to the 2.5th and 97.5th percentiles for the reference group, were established. The established RIs were then applied to the full unscreened data set to determine the prevalence of WBA values outside the RIs. RESULTS WBA RIs were established for all 6- to 19-year-olds and for 20- to 69-year-olds separated into three groups: females, males, and non-Hispanic Asians. The differences among the CDFs underlying these RIs corresponded to small effect sizes. When a single RI, 0.40 < average WBA < 0.75, was applied to the full data set, about 6%-13% of ears fell outside the derived RIs. Logistic regression analyses found abnormal tympanometric results to be responsible for the extreme WBA values among the general population. Abnormal tympanometric results increased the odds of having WBA values outside the RI by ≥ 300%. CONCLUSIONS U.S. population data for healthy ears were used to establish RIs for WBA of about 0.40-0.75. About 6%-13% of Americans, 6-80+ years of age, had WBA values outside these RI limits.

Abstract
Objective:To investigate the characteristics of wideband acoustic immittance(WAI) measurements in patients with unilateral Ménière's disease(MD) and evaluate the clinical value of WAI in diagnosis of MD. Methods:WAI was performed in 30 patients with unilateral MD(30 ears for symptomatic and 30 ears for asymptomatic) and in 26 healthy individuals(52 ears)(control group). The WAI measurements, including the frequency first appearing two peaks in energy absorbance(EA) tympanogram, resonance frequency(RF), the peak value of absorbance(PVA), the integral area of absorbance(IAA), EA curve at peak pressure, were analyzed. Results:①The occurrence of two peaks in EA tympanogram in both the MD symptomatic and asymptomatic ear was observed in 27 ears(84.4%), and 38 ears(70.4%) in the control group, with no significant difference in the frequency of first appearing in two peaks onset between the groups(all P>0.05). ②The RF of the MD symptomatic ears was significantly lower than that of the asymptomatic ears(t=-3.544, P=0.001) and that of the control subjects(t=2.084, P=0.041); there was no difference of RF between the MD asymptomatic ears and the control group(P>0.05). ③The PVA were significantly lower in both MD symptomatic(t=4.240, P<0.01) and asymptomatic ears(t=4.202, P=0.001) than in controls. ④The IAA in MD symptomatic(t=3.295, P=0.001) and asymptomatic ears(t=3.193, P=0.003) was significantly lower than in the control group. ⑤Comparison of the EA curve at peak pressure of the three groups: the EAs of MD symptomatic ears were lower than those of the control group at the range of 1 059-2 911 Hz(all P<0.05); the EAs of MD symptomatic ears were lower than those of MD asymptomatic ears within 1 000 Hz and 1 834-2 119 Hz(all P<0.05); the EAs of MD asymptomatic ears were lower than those of the control group at the range of 515-2 748 Hz(all P<0.05). Conclusion:Symptomatic ears in unilateral MD patients show alterations in some WAI measurements compared to asymptomatic ears and/or controls, suggesting that middle ear mechanical fuction of the affected side may be modified due to the endolymphatic hydrops. The clinical significance of WAI needs to be further explored in the context of evaluating MD.

Abstract
Abstract
Introduction Otosclerosis is characterized by the fixation of the stapes to the oval window, thereby impairing acoustic signal absorbance. A commonly used surgical technique for improving hearing in cases of otosclerosis is stapedotomy. However, it is unclear whether this surgery restores all the physical characteristics of the tympano-ossicular system.
Objective To evaluate the tympano-ossicular system in individuals with fenestral otosclerosis pre and poststapedotomy using wideband tympanometry.
Method A total of 47 individuals and 71 ears were assessed. The subjects were divided into three groups: presurgery otosclerosis; postsurgery; and a control group of normal-hearing adults. A handheld tympanometer with a wideband module (226–8,000 Hz) was used to take measurements at ambient pressure and under pressurized conditions. The level of statistical significance adopted was p ≤ 0.05.
Results Acoustic absorbance at 226 Hz was low for all groups. At frequencies in the range 630 to 5,040 Hz, each group had a characteristic absorbance curve, allowing them to be distinguished from one another. In the presurgery group, absorbance values were below normal levels, with energy absorbance below 10%. Low energy absorbance was most evident at 1,000 Hz in the presurgery group, but this was not observed in the postsurgery group. Although there was an improvement in hearing, the surgery failed to restore the tympano-ossicular system to normal.
Conclusion Wideband acoustic absorbance proved able to differentiate normal ears and otosclerotic ears pre and postsurgery, under both ambient pressure and pressurized conditions.

Abstract
Objective:Through analysis of the sound energy absorbance of wideband acoustic immittance to provide a basis for differential diagnosis of adult acquired secondary cholesteatoma of the middle ear and patients with chronic suppurative otitis media(CSOM). Methods:38 cases of cholesteatoma and 40 cases of CSOM admitted to the Department of Otolaryngology, Affiliated Hospital of Xuzhou Medical University from September 2020 to December 2021 were selected as the research group, and 30 cases (60 ears) of normal adults were selected as the control group. A total of 16 frequency points were selected, and the energy absorbance of wideband acoustic immittance was taken as the research parameter. The characteristics of energy absorbance under ambient pressure among the three are compared. Then the ROC in the cholesteatoma group was drawn, and by calculating the AUC, the Cut-off values and the corresponding sensitivity and specificity were found. Results:The energy absorbance in CSOM group at 1100-5700 Hz and the cholesteatoma group at 560-5700 Hz was lower than that in the control group, and the difference in some frequency bands was statistically significant. The energy absorbance in the cholesteatoma group at 226-7100 Hz was lower than that in the CSOM group, and the difference between the two groups in many frequency points was statistically significant. The ROC in the research group was drawn and it was found that the AUC in the 560, 710, 890, and 4500 bands was > 0.5, and in the other bands was > 0.7(P<0.05). The AUC in the 2800 Hz was the largest (0.78), the Cut-off value was 0.31, the corresponding sensitivity was 78.38%, specificity was 73.33%. Conclusion:Wideband acoustic immittance can be used as an auxiliary method for the differential diagnosis of adult-acquired secondary cholesteatoma of the middle ear and chronic suppurative otitis media in adults.
