“…Although some normative WBT data are available, variations by age, sex, ear side, medical device used, and ethnicity are considerable [7,9,21]. Thus, we designed our study by reference to earlier work done in our clinic and derived normative WBT data for the Turkish population [10]. The present study was conducted in the same ethnic group, using the same device.…”

“…Our results were not affected by ear side or sex. In terms of age group, only the RF of subjects aged 0–1 months differed from those of subjects aged 2 months to 20 years; the MARs and MAFs did not differ [10]. Subjects aged below 20 years differed from older subjects in these parameters, but all subjects aged over 20 years were similar.…”

“…WBT data are thus quite different from those obtained via tympanometry, affording extensive insight into the middle and inner ears, and facilitating identification of various pathologies. However, WBT is relatively new; few normative data are available [9,10]. WBT data from patients with various ear diseases/pathologies are scarce.…”

Objectives We explored whether wideband tympanometry (WBT) could be used as a screening test for superior semicircular canal dehiscence (SSCD), and obtained new WBT data (given that the test is not yet in common clinical use) on patients with SSCD. Methods We compared the WBT data of patients clinically and radiologically diagnosed with SSCD in our hospital between 2013 and 2018 to those of healthy volunteers. We compared the resonance frequency (RF), maximum absorbance frequency (MAF), and maximum absorbance ratio (MAR). The t -test was used for statistical analysis with the significance level set to P <0.05. In addition, we used receiver operating characteristic analysis to derive cutoff values for SSCD diagnosis in terms of sensitivity and specificity. Results Seventeen patients (four with bilateral and 13 with unilateral disease; 17 ears) diagnosed with SSCD and 27 healthy volunteers (47 ears) were included. The mean RFs of the SSCD patients and healthy subjects were 548.7 Hz (range, 243 to 853 Hz) and 935.1 Hz (range, 239 to 1,875 Hz), respectively ( P <0.001). The mean MARs of the SSCD patients and healthy subjects were 89.4% (range, 62% to 100%) and 82.4% (range, 63% to 99%), respectively ( P =0.005). The mean MAFs of the SSCD patients and healthy subjects were 1,706.3 Hz (range, 613 to 3,816 Hz) and 2,668 Hz (range, 876 to 4,387 Hz), respectively ( P <0.001). In terms of SSCD diagnosis, a MAR above 86% afforded 81% sensitivity and 77% specificity; an RF below 728 Hz, 86% sensitivity and 81% specificity; and an MAF below 1,835 Hz, 79% sensitivity and 67% specificity. Conclusion WBT may be a useful clinical screening test for SSCD. The RF and MAF were lower, and the MAR higher, in SSCD patients than in normal controls.

“…Only a few case-study and small-scale reports of preliminary normative WBT data exist for children (Keefe & Simmons 2003; Keefe et al 2012; Özgür et al 2016; V. Aithal et al 2019, 2020). These studies generally report a lack of ear effects (Özgür et al 2016; V. Aithal et al 2019) and only some of the evidence suggests small, statistically significant yet clinically irrelevant gender and ethnicity effects (Kenny 2011; V. Aithal et al 2019). None of these studies investigated the effects of age.…”

Wideband Tympanometry Findings in School-aged Children: Effects of Age, Gender, Ear Laterality, and Ethnicity

Objectives: Wideband tympanometry (WBT) measures middle-ear function across a range of frequencies (250 to 8000 Hz) while the earcanal pressure is varied from +200 to -300 daPa. WBT is a suitable test to evaluate middle-ear function in children, but there is a lack of age-, ear-, gender-, or ethnicity-specific data throughout the literature. The purpose of this study was to investigate the effects of age, ear laterality, gender, and ethnicity on the WBT data retrieved from children aged 4 to 13 years determined to have normal middle-ear function.Design: Data were collected cross-sectionally from 924 children aged 4 to 13 years who passed a test battery consisting of 226-Hz tympanometry, ipsilateral acoustic stapedial reflexes, and pure-tone screening, and without significant history of middle-ear dysfunction. Participants were grouped according to their age: 4 to 6 years, 7 to 9 years, 10 to 13 years. Wideband absorbance values were extracted at 0 daPa (WBA 0 ) and tympanometric peak pressure (WBA TPP ). Results:The effects of age, frequency, and pressure (WBA 0 versus WBA TPP ) were statistically significant. There were significant differences between WBA 0 and WBA TPP for all age groups such that WBA 0 had lower absorbance at low frequencies (250 to 1600 Hz) and greater absorbance at mid to high frequencies (2500 to 8000 Hz). Statistically significant effects of age were present for WBA 0 and WBA TPP such that absorbance generally increased with age from 250 to 1250 Hz and decreased with age from 2000 to 5000 Hz. There were no significant main effects of gender, ear, or ethnicity. Conclusions:Gender-, ear-, and ethnicity-specific clinical WBA 0 and WBA TPP norms are not required for diagnostic purposes; however, agespecific norms may be necessary. Age-related changes in middle-ear function were observed across WBA 0 and WBA TPP . The data presented in this study are a suitable clinical reference for evaluating the outer-and middle-ear function of school-aged children.

“…In recent years, the application of WBA in healthy neonates has been extensively studied, and consequently, normative data for this population have been established [ 8 - 12 ]. Taken together, a general pattern of WBA has consistently been observed in most studies, with absorbance being lowest at frequencies below 1,000 Hz and above 4,000 Hz and highest in the frequency region between 1,000 Hz and 4,000 Hz.…”

Background and ObjectivesAlthough ethnicity effect on wideband absorbance (WBA) findings was evident for adults, its effect on neonates has not been established yet. This study aimed to investigate the influence of ethnicity on WBA measured at 0 daPa from neonates with healthy middle ear functions.Subjects and MethodsParticipants were 99 normal, healthy, full-term newborn babies with chronological age between 11 and 128 hours of age (mean=46.73, standard deviation=26.36). A cross-sectional study design was used to measure WBA at 16 one-third octave frequency points from 99 neonates comprising of three ethnic groups: Malays (n=58), Chinese (n=13) and Indians (n=28). A total of 165 ears (83.3%) that passed a battery of tests involving distortion product otoacoustic emissions, 1 kHz tympanometry and acoustic stapedial reflex were further tested using WBA. Moreover, body size measurements were recorded from each participant.ResultsThe Malays and Indians neonates showed almost identical WBA response across the frequency range while the Chinese babies showed lower absorbance values between 1.25 kHz and 5 kHz. However, the differences observed in WBA between the three ethnic groups were not statistically significant (p=0.23). Additionally, there were no statistically significant difference in birth weight, height and head circumference among the three ethnic groups.ConclusionsThis study showed that Malays, Chinese and Indians neonates were not significantly different in their WBA responses. In conclusion, to apply for the ethnic-specific norms is not warranted when testing neonates from population constitute of these three ethnicities.
