Methods: All patients underwent an ENT physical examination, an MRI scan, videonystagmography, an o-VEMP test, and a v-HIT test. The patients who had central-type vertigo, PBBV, and vestibular migraine were excluded from the study. Overall, 30 patients were included in the study. Results: Canal paralysis was observed in 22 patients (73.3%). Pathological o-VEMP and v-HIT test results were obtained in 19 (63.3%) and 8 (26.7%) patients, respectively. Pathological o-VEMP or v-HIT was observed in 17 of 22 (77.3%) patients with canal paralysis. Sensitivity and specificity of a combination of o-VEMP and v-HIT test results for detecting canal paralysis were 77.3% and 80.1%, respectively. Conclusion: It does not seem that o-VEMP and v-HIT tests can replace the caloric test to detect vestibular hypofunction. However, these two tests can be used as first-line tests to initiate vestibular evaluation. If one of these two tests shows vestibular hypofunction, there is no need to perform a caloric test.

The aim of this study is to evaluate the benefits and satisfaction of the users from the hearing aids whose fitting are done suitably for hearing loss including ear mould. Material and method: In this study Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire which consists of 24 questions was used for hearing aid satisfaction assessment. Total 301 people having different type and degree hearing loss participated in the study. The ages of 141 men and 160 women participants were between 18-65 and the average age was 49.11 ± 13.89 year. 187 of the participants had hearing aid in only one ear and the 114 had in both ears. Degree of unilateral hearing loss was 31 slight, 64 moderate, 49 moderately severe, 35 severe and 8 profound. In the ear in which hearing aid was used, there was 134 sensorineural hearingloss, 53 mixture hearing loss. Degree of hearing loss of the people using hearing aid bilaterally was 24 slight, 79 moderate, 54 moderately severe, 48 severe and 23 profound. In 162 ears of people using hearing aid bilaterally there was sensorineural hearing loss and in 53 ears there was mixture hearing loss. Results: In right ear average score of the maximum satisfaction was between 4.23-5.75 and in left ear it was between 4.20-5.72. While the degree of hearing loss was increasing, the average of satisfaction score was decreasing. In terms of using unilateral and bilateral hearing aid, statistically considerable difference was found. In terms of hearing loss statistically considerable difference couldn't be found. Conclusion: Satisfaction of hearing aid is decreasing inversely proportional with increasing of hearing loss (slight-profound degree) While the furthest satisfaction for right and left ear was slight degree, the least satisfaction was observed for profound hearing loss. Aid using satisfaction changes depend on using the aid in the right ear or in the left ear. Using bilateral hearing aid has increased patient satisfaction much more.

The aim of this study is to evaluate Meniere's disease patients with vestibular test battery as Videonystagmography (VNG), Vestibular Evoked Myogenic Potentials (VEMPs) and Video Head Impulse Test (V-HIT) to assess peripheral and central vestibular systems. Methods: 16 bilateral, 17 unilateral patients suffering from MD (mean age, 40.90 years, range, 23 to 66 years; 20 women and 13 men) comprised the study group, and 39 healthy (mean age, 38.10 years, range from 21 to 60 years; 22 women and 17 men) volunteers formed control group. Evaluation of peripheral and central vestibular systems changes with oculomotor tests, caloric test, C-VEMPs, O-VEMPs, and the evaluation of the vestibular ocular reflex (VOR) using the V-HIT. Result: Twenty-six ears out of the forty-nine ears that were affected by Meniere's disease were diagnosed as otolith or ampullary dysfunction. As to O-VEMPs testing, N1 and P1 waves could not be obtained from thirty of the forty-nine ears affected by Meniere's disease. As for obtained N1 and P1 waves, prolonged N1 and P1 wave latencies, and reduced amplitude was observed in Meniere's group. P1 and N1 waves were not observed in 5 bilateral and 2 unilateral Meniere's patients (12 ears out of 49 affected ears) in C-VEMPs recordings (23.9%). In Meniere's patients' group, 44.9% of the velocity gain values were obtained in the pathologic borders of v-HIT. In addition to lower velocity gain, higher ratios of asymmetry were obtained from the ears affected with Meniere's disease. Conclusion: According to these results, it can be concluded that Meniere's disease significantly affects the peripheral vestibular system but the functions of the central vestibular system were not affected.

The ages of 141 men and 160 women participants were between 18-65 and the average age was 49.11 ± 13.89 year. 187 of the participants had hearing aid in only one ear and the 114 had in both ears. Degree of unilateral hearing loss was 31 slight, 64 moderate, 49 moderately severe, 35 severe and 8 profound. In the ear in which hearing aid was used, there was 134 sensorineural hearingloss, 53 mixture hearing loss. Degree of hearing loss of the people using hearing aid bilaterally was 24 slight, 79 moderate, 54 moderately severe, 48 severe and 23 profound. In 162 ears of people using hearing aid bilaterally there was sensorineural hearing loss and in 53 ears there was mixture hearing loss. Results: In right ear average score of the maximum satisfaction was between 4.23-5.75 and in left ear it was between 4.20-5.72. While the degree of hearing loss was increasing, the average of satisfaction score was decreasing. In terms of using unilateral and bilateral hearing aid, statistically considerable difference was found. In terms of hearing loss statistically considerable difference couldn't be found. Conclusion: Satisfaction of hearing aid is decreasing inversely proportional with increasing of hearing loss (slight-profound degree) While the furthest satisfaction for right and left ear was slight degree, the least satisfaction was observed for profound hearing loss. Aid using satisfaction changes depend on using the aid in the right ear or in the left ear. Using bilateral hearing aid has increased patient satisfaction much more.

Material and method: 24 children (11 boys, 13 girls) with bilateral profound sensorineural hearing loss participated in this study. Age of children ranged between 13 and 60 months (mean 30 months). All participated children were implanted with Cochlear® Nucleus brand devices. In preoperative ABR evaluation with click stimulus in 100 dBnHL intensity level, 9 children showed wave V and 15 children did not. We compared intraoperative NRT results of 1 st , 6th, 11 th , 16 th and 22 nd electrodes, those were selected from 22 electrodes, of the two groups. Results: There was no statistically significant difference between the children who showed wave V and who did not in preoperative ABR, when compared the intraoperative NRT results of 1 st , 6 th , 11 th , 16 th and 22 nd electrodes (p>0,05). Conclusion: intraoperative NRT was obtained in all the implanted children with bilateral profound sensorineural hearing loss, even if they received wave V or not in preoperative ABR. There was no difference between any of the parameters of the test results of the two groups. Normal NRT results can be achievable when there is no wave V in preoperative ABR.

The aim of this study is to evaluate Meniere's disease patients with vestibular test battery as Videonystagmography (VNG), Vestibular Evoked Myogenic Potentials (VEMPs) and Video Head Impulse Test (V-HIT) to assess peripheral and central vestibular systems. Methods: 16 bilateral, 17 unilateral patients suffering from MD (mean age, 40.90 years, range, 23 to 66 years; 20 women and 13 men) comprised the study group, and 39 healthy (mean age, 38.10 years, range from 21 to 60 years; 22 women and 17 men) volunteers formed control group. Evaluation of peripheral and central vestibular systems changes with oculomotor tests, caloric test, C-VEMPs, O-VEMPs, and the evaluation of the vestibular ocular reflex (VOR) using the V-HIT. Result: Twenty-six ears out of the forty-nine ears that were affected by Meniere's disease were diagnosed as otolith or ampullary dysfunction. As to O-VEMPs testing, N1 and P1 waves could not be obtained from thirty of the forty-nine ears affected by Meniere's disease. As for obtained N1 and P1 waves, prolonged N1 and P1 wave latencies, and reduced amplitude was observed in Meniere's group. P1 and N1 waves were not observed in 5 bilateral and 2 unilateral Meniere's patients (12 ears out of 49 affected ears) in C-VEMPs recordings (23.9%). In Meniere's patients' group, 44.9% of the velocity gain values were obtained in the pathologic borders of v-HIT. In addition to lower velocity gain, higher ratios of asymmetry were obtained from the ears affected with Meniere's disease. Conclusion: According to these results, it can be concluded that Meniere's disease significantly affects the peripheral vestibular system but the functions of the central vestibular system were not affected.

Therefore, it also interacts with emotions in listeners. Music sounds are in the range of approximately 20-8000 Hz. This frequency range is within the frequency spectrum of the human cochlea. The aim of this research is to evaluate the hearing thresholds of music teachers and to determine whether they cause tinnitus. MATERIAL AND METHODS This research was conducted in Turgut Özal University Medical Faculty Hospital Audiology and Speech Disorders clinic. A total of 35 people (17 music teachers, 18 control groups) participated in the research. In this research, 17 music teachers (11 females, 6 males) aged 24-39, and 18 volunteers (12 females, 6 males) participated in the control group. After the otoscopic examination of all participants, pure tone audiometry (in the range of 125-16,000 Hz), immitansmetric examination and Distortion Product Otoacoustic Emission (D...
