“…In addition, this study proved a strong correlation between the body size and ECV. [6] In another study determining normative values of WBT, RF did not show a significant difference according to sex. [7] In addition, a study investigating the effect of septum deviation on middle ear RF reported that RF was not affected by sex and age.…”

Objectives:The aim of this study was to investigate the possible effects of body mass index (BMI) on traditional 226 Hz tympanometry and wideband tympanometry (WBT) to gain a better understanding of resonance frequency.Patients and Methods: A total of 158 ears of 79 volunteers (19 males, 60 females; mean age: 20.5 years; range, 18 to 27 years) who had normal hearing and normal otoscopic examination findings were included in the study between October 2019 and June 2020. By measuring the weight and height of the participants, their BMI values were classified into three groups: ≤18.5 kg/m 2 (underweight), 18.5 to 24.9 kg/m 2 (normal weight), and ≥25.0 kg/m 2 (overweight). Tympanometric evaluations were conducted using the Interacoustics-Titan WBT. Results:The difference of ear canal volume (ECV) was significant between the two sexes (p<0.05), while there was no significant difference in the tympanometric peak pressure, compliance, gradient, and resonance frequency between the sexes (p>0.05). A significant difference was found in the ECV and resonance frequency among the three BMI groups (p<0.05). Accordingly, as the BMI increased, the ECV increased and the resonance frequency decreased (p<0.05). Conclusion:The BMI may affect ECV and resonance frequency values which should be considered during the examination.

“…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].…”

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.

“…In addition, Keefe et al (2012) reported that WAI can also be used to predict CHL. Consequently, researchers from various countries have begun to develop normative values for WAI to improve its diagnostic utility (Aithal et al 2017;Chang et al 2019;Jaffer 2016;Margolis, Saly & Keefe 1999;Polat et al 2015;Sebothoma & Khoza-Shangase submitted;Shahnaz, Feeney & Schairer 2013). Over and above their sensitivity, these measures of middle ear pathologies have also been shown to be easy to perform Hunter & Sanford 2015) and, therefore, can easily be incorporated into the tasks transferred during task-shifting to paraprofessionals.…”

Peer review declarationThe publisher (AOSIS) endorses the South African 'National Scholarly Book Publishers Forum Best Practice for Peer Review of Scholarly Books'. The manuscript underwent an evaluation to compare the level of originality with other published works and was subjected to rigorous two-step peer review before publication, with the identities of the reviewers not revealed to the editor(s) or author(s). The reviewers were independent of the publisher, editor(s), and author(s). The publisher shared feedback on the similarity report and the reviewers' inputs with the manuscript's editor(s) or author(s) to improve the manuscript. Where the reviewers recommended revision and improvements, the editor(s) or author(s) responded adequately to such recommendations. The reviewers commented positively on the scholarly merits of the manuscript and recommended that the manuscript be published. v Research justificationPreventive health care, where preventive audiology is positioned, contains strategies adopted and implemented for disease and disorder prevention. Hearing function can be negatively impacted by numerous factors, including lifestyle choices, environmental factors, genetic predisposition, the burden of disease and other causes. Frequently, hearing impairment can be prevented and its consequences significantly minimised by preventive measures. Such prevention commands conscientiously deliberate anticipatory actions that can fall under primordial, primary, secondary or tertiary levels of prevention. South Africa, as a resource-constrained low-and middle-income country (LMIC), still has a challenge of high numbers of individuals with preventable hearing impairment from the cradle to the grave. Numerous strategies exist for the prevention of hearing impairment across all ages and in various contexts. Preventive Audiology: An African Perspective is an original scholarly book that introduces the concept of preventive audiology, with a specific focus on the African context, which is in line with the South African re-engineered primary health care strategy and the World Health Organization's approach. The book reflects on contextually relevant and responsive evidence-based perspectives, grounded in an African context on preventive audiology, in four major ear-and-hearing burdens of disease within the South African context, namely, (1) early hearing detection and intervention (EHDI), (2) middle ear pathologies, (3) ototoxicity and (4) noise-induced hearing loss (NIHL). The book represents innovative research, seen from both South African and global perspectives. It offers new discourse and argues for a paradigm shift in how audiology is theorised and performed, particularly in LMIC contexts. The goal of this book is to motivate for a paradigm shift in how ear-and-hearing health care is approached within this LMIC context, while also arguing for Afrocentric best practice evidence that leads to next practice. For Afrocentric epistemology, which is a different narrative that is deliberately removed from Western epi...
