This study aimed to evaluate the effect of this strategy on the clinical performance of audiology students. Methods: In this quasi-experimental study, 30 fourth-year undergraduate students in audiology participated. They were assigned into two groups of traditional learning and gallery walk. The educational content of both groups was similar and was related to the adult care clinical practicum. The assessments included Eustachian tube function test, site-of-lesion tests, and clinical masking. The clinical knowledge, and satisfaction level of students were compared before and after intervention. Results: Before the intervention, the difference in clinical knowledge was not statistically significant between the two study groups (p>0.05). After the intervention, we observed a considerable improvement in knowledge scores in both groups, mostly in the gallery walk group. The mean scores of site-of-lesion tests, and total score of knowledge were also significantly higher in the gallery walk group (p<0.05). The satisfaction level of students was above the average level (mean score=3.9±0.74). Conclusion: The gallery walk strategy has more positive effects on clinical practice of audiology students compared to traditional learning strategy. https://avr.tums.ac.ir/index.php/avr/article/view/1020 https://avr.tums.ac.ir/index.php/avr/article/download/1020/468

Therefore, this study aimed to compare the vestibular function between Iranian BD patients and normal subjects using cervical vestibular- evoked myogenic potentials (cVEMPs) and video head impulse test (vHIT). Methods: In this cross-sectional study, 44 patients with definitive BD in the inactive stage of disease and 30 age and sex matched normal subjects were evaluated via cVEMP and vHIT tests and dizziness handicap inventory (DHI). Then the parameters of the tests were compared between the two groups by statistical methods. Moreover, the effects of DHI scores and other contextual variables on the test results were examined. Results: In terms of the cVEMP test, the response rate and mean latency of p13 in the left ear were significantly lower, the amplitude of the cVEMP wave in the left ear and the amplitude asymmetry ratio were significantly higher in BD patients compared to normal subjects (p<0.05). Fifteen BD patients had abnormal amplitude and nine patients had abnormal latency of cVEMP responses. In terms of the vHIT test, the mean vestibule-ocular reflex gain of the left posterior semicircular canal and the mean gain asymmetry ratio of lateral canals were significantly higher in BD patients than in the controls (p<0.05). Conclusion: the vestibular system of some patients with BD is disturbed and the results of this study indicate the presence of unilateral vestibular weakness in BD. So vestibular assessment can be helpful for these patients. https://avr.tums.ac.ir/index.php/avr/article/view/1029 https://avr.tums.ac.ir/index.php/avr/article/download/1029/464

Such a material helps in conducting the speech tests for native Arab children with Syrian accent. This work is a part of a complete project on preparing and validating the necessary materials for speech and central auditory processing tests for the Arabic Syrian community. Methods: In this cross-sectional comparative study, two sets of phonetically balanced monosyllabic word lists were constructed. The two selected 25-monosyllabic word lists were presented to 50 normal hearing participants with the age range of 5 to 10 years. Tests of validity and reliability were conducted to assure the suitability of this material for the word recognition test. The test was repeated for the same children after three weeks. Results: The two word lists have shown high face and content validity, Cronbach`s alpha coefficient was 0.79, 0.85 for the two lists respectively. Factor validity has shown that the test materials are one-dimensional, the first factor achieved 57.25 and 53.13 of the variance. Test-retest reliability (p<0.001) and Intraclass Correlation Coefficients reliability (p<0.001) were also significant. Conclusion: The data analysis shows that the Syrian version of the word recognition test has high degree of validity and reliability. Therefore, developing the Syrian version of the scale has good psychometric properties, which makes it appropriate for the local use. https://avr.tums.ac.ir/index.php/avr/article/view/1023 https://avr.tums.ac.ir/index.php/avr/article/download/1023/457

Comorbidities such as Diabetes Mellitus is known as the most common cause of CKD and a significant risk factor for sensorineural hearing loss (SNHL). The aim of this study was to compare SNHL among diabetic with non-diabetic hemodialysis patients. Methods: In this study, 33 diabetic patients on hemodialysis were selected from Hami center, Arak, Iran. Non-diabetic subjects were 31 hemodialysis patients without diabetes were matched for age, duration of CKD and hemodialysis. Data were obtained via questionnaire, patients’ files, physical examination, otoscopy and tympanometry. Hearing was analyzed using pure-tone audiometry for both groups. Results: In the study, 66.2% of diabetic patients and 52.1% of non-diabetic subjects had SNHL. Results showed that diabetic patient has 1.3 times more likely to have hearing impairment. This difference was not statistically significant. Bilateral mild SNHL was the most prevalent in both groups. No significant difference was reported in SNHL prevalence, mean thresholds of hearing and ear laterality between the groups. Gender and age had a significant effect on hearing loss after adjusting covariables. No significant association was found between diabetes and hearing loss. Conclusion: SNHL was more common in hemodialysis patients with diabetes. Patients with diabetes had poorer hearing thresholds compared to non-diabetic group, with no significant difference between groups. The periodical assessment of hearing and extending audiological care in this high-risk population is recommended due to long-term irreversible symptoms of the disease. https://avr.tums.ac.ir/index.php/avr/article/view/1030 https://avr.tums.ac.ir/index.php/avr/article/download/1030/463

Video head impulse test (vHIT) is a reliable test for assessing the function of semicircular canals (SCCs). This study aimed to determine the early effect of CI on SCCs function, by comparing pre- and post-operative vHIT results. Methods: In this cross-sectional study, participants were 22 adults with SNHL scheduled for unilateral CI in the right ear and 22 age-matched healthy subjects as a control group. The vHIT was conducted before and two weeks after CI. Results: The mean vHIT gains in the SNHL group were significantly lower than in controls, with a large effect size. Furthermore, the mean vHIT gains in the right lateral SCCs (p<0.001) and right anterior SCCs (p=0.003) were significantly reduced after CI, compared to the gain values before CI, with a large pooled effect size. However, these differences were not statistically significant for the right posterior SCCs. The comparison of vHIT gains in the nonimplanted ear showed no statistically significant difference between pre- and post-operative phases. Conclusion: The vHIT is a useful clinical method to detect the early effects of CI on the function of SCCs. These effects are more obvious in the lateral and superior SCCs in the implanted ear. https://avr.tums.ac.ir/index.php/avr/article/view/1035 https://avr.tums.ac.ir/index.php/avr/article/download/1035/475

Methods: Thirty patients were included in this prospective study, who underwent revision myringoplasty for chronic otitis media without cholesteatoma in the period between 2017-2019 in the Department of Ear, Nose, and Throat-Head and Neck Surgery in Almowasat University Hospital. Data of all patients: perforation size and site, middle ear status, surgical approach, graft material, pre and postoperative morphological and functional results were assessed. The temporal fascia was used for the reconstruction of TM. The interrelation between multiple preoperative parameters and postoperative morphological (closure of the perforation) and functional (hearing level) outcomes were assessed. Results: Successful closure rate of the TM perforation was 86.66% and failure rate was 13.34% in revision myringoplasty. The improvement of the air bone gap between 10-20 dB was 76.66% while the air bone gap between 20-30 dB was unchanged 23.33%. Conclusion: Revision myringoplasty can offer reasonably good chances for postoperative graft healing and hearing improvement with a high success rate. This gives the patient a good benefit in protecting the ear from developing complications that may have poor structural changes in the middle ear (ossicular necrosis and tympanosclerosis) which in turn leads to hearing loss. https://avr.tums.ac.ir/index.php/avr/article/view/1034 https://avr.tums.ac.ir/index.php/avr/article/download/1034/462

This study aimed to translate the Dizziness Handicap Inventory for Patient Caregivers (DHI-PC) into Persian (DHI-PC-P) and assess its psychometric properties for children aged 5–12 years. Methods: This is a descriptive-analytical psychometrics study. After obtaining permission from the developers of the DHI-PC, translation into Persian and cross-cultural adaptation were done according to the international guidelines for self-assessment tools recommended by the American Association of Orthopedic Surgeons. Participants were 21 parents (mean age: 38.05 years, SD=6.1 years, 18 female) and their children with dizziness (mean age 8.69 years, SD=2.41 years, 9 female) between the ages of 5–12 years old. Face validity, content validity, and test-retest reliability at an interval of 14–21 days were evaluated for the DHI-PC-P. Results: The face validity was confirmed qualitatively by the experts’ opinions and quantitatively by calculating the item impact score. Content validity was confirmed by calculating the content validity index and the content validity ratio (0.97 and 0.86, respectively). The internal consistency was good (Cronbach’s alpha=0.90). For the testretest reliability, the intraclass correlation coefficient was obtained 0.94, indicating an excellent reliability. Conclusion: The DHI-PC-P can be used clinically as a valid and reliable tool for children with dizziness aged 5–12 years. https://avr.tums.ac.ir/index.php/avr/article/view/1178

The present study focused on the survey of parental satisfaction on listening therapy of their Hearing-Impaired (HI) children in tele and face-to-face mode during COVID-19 pandemic. Methods: Parents of children with Hearing Impairment (HI) who attended tele and face-toface therapy sessions participated in the study. Group I participants were 25 parents of 0–3 years’ children with HI (mean age 1.8±0.25 y), while Group II had 25 parents of children with HI aged 3.1–5 years (mean age 4.1±0.33 y). The adapted and validated questionnaire was administered. Results: Frequency count and percentage were detailed for all questions across groups. The chi-square test of association revealed a significant difference between the tele and face-to-face therapy across the ratings in both groups, with parents rating better satisfaction and therapy efficacy in face-to-face therapy compared to tele-therapy. Principal Component Analysis (PCA) revealed that few questions can best categorize the variance in satisfactory ratings between the two therapy conditions. Conclusion: The findings of the study showed that tele-listening therapy appears to be a promising rehabilitative option in the COVID-19 pandemic when factors affecting its successful implementation are considered, although in the present conditions parental satisfaction ratings are higher for face-to-face therapy. https://avr.tums.ac.ir/index.php/avr/article/view/1177

Yet diagnostic hearing tests are not readily accessible to seniors in the community. Since 2018, the Ministry of Health in Singapore started a pilot program to screen them for their visual, oral, and hearing health in the community and improve accessibility to hearing healthcare. We describe the clinical characteristics of seniors presenting to Community Hearing Clinic (CHC) and compared hearing aid uptake rates with patients seen at a tertiary hospital. Methods: Retrospective cross-sectional descriptive study on Singaporeans with hearing difficulties presenting to the community clinics. Results: Attendance rates were generally positive at more than 80% and is comparable to the specialist outpatient clinic at the tertiary hospital. Hearing aid uptake rates were comparable between CHC and tertiary hospital at 61.9% and 66.9% respectively. Despite having better accessibility with direct access to the audiologists, and more financial subsidies, the eventual uptake rates of hearing aids are not clinically different at the CHC. Conclusion: CHC may be a viable model of improving accessibility to hearing healthcare with audiologists providing the 1st level of triaging safely. However, the cost-effectiveness of this model remains to be seen. Further health service research studies are warranted to determine the cost-effectiveness of sandbox CHC. Right-siting and expanding the sandbox to include access to hearing aid subsidies in private clinics may further help with this move beyond hospital to the community in line with our public health vision. https://avr.tums.ac.ir/index.php/a
