Introduction: In this study we aimed to review immediate effects of pulse steroid therapy versus common steroid therapy in patients with idiopathic Sudden Sensory- Neural Hearing Loss. Materials and Methods: In this clinical trial study 50 patients with SSNHL in less than 24 hours before referral were involved. The causes of hearing loss should be rejected and if the cause was identified, the patient would be excluded. Pulse therapy group received Methyl Prednisolone 10 mg /kg for three days and then continued by prednisolone 1 mg /kg for ten days and common therapy group received prednisolone 1 mg /kg for ten days. Average hearing threshold of the patients in frequencies of 500, 1000, and 2000 Htz, average SDS of patients and patient recovery was compared between two groups based on hearing tests and guidelines. Results: Fifty patients with average of 46 ±15.69 years were studied. There was no significant difference in average of hearing threshold in different frequencies and SDS between two groups. Mean hearing recovery was 10.69 db in common steroid group and it was 13.51 db in pulse steroid group. Although the mean of hearing recovery was higher in the pulse steroid group compare the common steroid group, there was no significant difference in hearing recovery after the treatment between two groups. Conclusion: According to the results pulse steroid is not preferable rather than common steroid therapy in terms of immediate therapeutic effects on SSNHL.

Potential Risk Factors

BackgroundMilitary aviators are potentially at risk for developing noise-induced hearing loss. Whether ambient aircraft noise exposure causes hearing deficit beyond the changes attributed to natural ageing is debated. The aim of this research was to assess changes in hearing thresholds of Israeli Air Force (IAF) pilots over 20 years of military service and identify potential risk factors for hearing loss.MethodsA retrospective cohort analysis was conducted of pure-tone air conduction audiograms of pilots, from their recruitment at 18 years of age until the last documented medical check-up. Mean hearing thresholds were analysed in relation to age, total flight hours and aircraft platform. Comparisons were made to the hearing thresholds of air traffic controllers (ATCs) who were not exposed to the noise generated by aircraft while on duty.ResultsOne hundred and sixty-three pilots were included, with flying platforms ranging from fighter jets (n=54), combat helicopters (n=27), transport helicopters (n=52) and transport aircraft (n=30). These were compared with the results from 17 ATCs. A marked notch in the frequency range of 4–6 kHz was demonstrated in the mean audiograms of all platforms pilots, progressing with ageing. Hearing threshold shifts in relation to measurements at recruitment were first noted at the age of 30 years, particularly at 4 kHz (mean shift of 2.97 dB, p=0.001). There was no statistical association between flying variables and hearing thresholds adjusted for age by logistic regression analysis.ConclusionsThe audiometric profile of IAF pilots has a pattern compatible with noise exposure, as reflected by characteristic noise notch. However, no flight variable was associated with deterioration of hearing thresholds, and no significant difference from non-flying controls (ATCs) was seen.

Background. Our study aimed to investigate an association between ocular pseudoexfoliation (PXF) and sensorineural hearing loss (SNHL) and to compare them with age and sex matched controls without pseudoexfoliation.Method. This was a case-control study of 123 patients which included 68 cases with PXF (at least one eye) and 55 controls without pseudoexfoliation. Pure-tone audiometry (PTA) was done for these patients at sound frequencies taken as important for speech comprehension, that is, 250 Hertz (Hz), 500 Hz, 1000 Hz, and 2000 Hz.Results. There were 41 patients with pseudoexfoliation syndrome (PXE) and 27 with pseudoexfoliative glaucoma (PXEG). The majority of patients with hearing loss (60%;n=51) were PXF patients and the remaining 40%(n=34)were controls. Below average hearing thresholds were significantly higher in the pseudoexfoliation group compared to the control group (P=0.01; odds ratio (OR), 3.00; 95% confidence interval (CI), 1.25–7.19). However, there was no significant difference in the mean hearing threshold levels between the three groups (PXE, PXEG, and controls) in either ear (ANOVA, right ear:P=0.46and left earP=0.36).Conclusion. Our study found an association between PXF and SNHL, confirming that PXF can involve organs in the body other than the eye.

Noise exposure in the working environment is a major cause of hearing impairment for workers; an audiogram hearing threshold level above 20 dB is considered irregular. In this study, audiometric data were analyzed with the objective of assessing hearing loss among power plant workers based on their age, noise exposure level, years of working, and work characteristics. A cross-sectional study was conducted to assess hearing level data for 672 workers reserved by the Health Care Unit of the power plant. The most recent audiometric data presented during 2013-2015 were used in the statistical analysis at 5 % level of significance. It was found that the most dominant frequency with reference to age and work experience is the test frequency at 4,000 Hz. The most prominent suffering significant hearing loss for both ears is the age group of 50-60 years, consistent with more than 35 years of working. The most significant exposure level is noise level at 81-84 dBA for the left ear only. The work characteristics were found to be the most significant factor affecting hearing loss in both ears. The t-test reveals no significant difference in hearing loss in both ears at all test frequencies. Hearing loss is found to occur at 4,000 and 6,000 Hz; therefore, there is a necessity to implement noise control measures specifically for each work group. Although there is an educational and training program in the power plant, all workers should still be educated continuously on how to use hearing protection equipment correctly to enhance awareness of the hazards of noise to hearing. Periodic audiometry should be performed to early detect noise-induced hearing loss specifically the notch occurring at 4,000 and 6,000 Hz, together with engineering control in order to reduce unwanted sound.

Background/Aim. Sudden sensorineural hearing loss is manifested by the loss of hearing for more than 30 dB at three consecutive frequencies in the timeframe of 72 h. It is of unclear etiology and pathogenesis, which leads to the use of different therapeutic methods. Treatment protocols are not compliant, making it difficult to objectively quantify their impact. The aim of this study was to show the effect of hyperbaric oxygen therapy as the only method for the treatment of sudden sensorineural hearing loss. Methods. This retrospective study included 20 patients treated for sudden sensorineural hearing loss with hyperbaric oxygenation (HBO) in the period from 2004 to 2014. The study was conducted in the specialized medical clinic for hyperbaric and underwater medicine, HBO Medical Center in Belgrade. The patients were treated according to the following protocol: a session of 60 min at the pressure of 2 bars (2ATA) two times a day, a total of 30 sessions. Assessment of the therapy effects was performed by observing the change in the hearing threshold at the frequencies of 500, 1,000, 2,000 and 4,000 Hz at the end of the treatment. Results. After the completion of treatment according to the protocol, a full hearing recovery (total improvement of hearing damage or achieving final hearing threshold above 25 dB) was found in 11 (55%) of the patients. A partial recovery (hearing improvement of up to 15 dB, and a final hearing threshold below 45 dB) occurred in 4 (20%) of the patients. In 5 (25%) of the patients, improvement was not verified (there was no recovery or it was less than 5 dB). The average absolute hearing recovery was 24.94 dB. The mean relative hearing recovery was 65.45%. Conclusion. Because of the unclear multifactorial etiopathogenesis of this disease, there are many therapeutic protocols. Based on the results of our study HBO therapy could be recommended primarily as the treatment for sudden sensorineural hearing loss.

A recently published prospective study on acute sensorineural deafness in Lassa fever among a West African population showed the audiometric pattern of a known virally induced hearing loss. Using the audiometric data from the patients with Lassa fever in that study, we analyzed and classified the initial hearing loss and final recovery into three groups by pure-tone average values and then did the same for 222 patients with idiopathic sudden hearing loss (SHL) in our study. Statistical analyses of the severity of initial hearing loss and the hearing recovery pattern indicate that the clinical course of our 222 patients with idiopathic SHL showed no statistically significant differences from the clinical course of the patients with Lassa fever. We found a marked difference in age, however, and a clinically significant difference in the incidence of bilateral hearing loss. In reviewing the literature on sudden sensorineural hearing loss, we found no apparent relation between severity of viral illness and initial hearing loss or subsequent recovery. Cummins et al. suggest that virally induced hearing loss in Lassa fever is linked to the host's immune response and not to the viremia. We thus propose a virally induced immune response mechanism for idiopathic sensorineural SHL. Further prospective studies are needed for verification.

Abstract Objective The aim of this study was to compare the effectiveness of intratympanic (IT) steroid therapy and combined intravenous-cum-intratympanic (IVIT) steroid therapy in the management of sudden sensorineural hearing loss (SSNHL). Study Design This was a nonrandomized clinical trial. Setting Tertiary referral center. Patients Forty-four patients, who presented to the outpatient department or the emergency room and those who fulfilled the inclusion criteria, were enrolled in this study. The patients were put into two groups: Group IT—that received intratympanic steroid therapy alone and Group IVIT—that received intratympanic as well as intravenous steroid therapies. Intervention Therapeutic—in the form of IVIT steroid therapy. Main Outcome Measure Impact of the steroid therapy in patients with SSNHL was measured objectively with the help of pure tone audiometry (PTA). The improvement in hearing was assessed in terms of decibels gained after the intervention in both the groups. Results The mean improvement in PTA after 3 months in Group IT was 19.78 (±18.918) dB, whereas the mean improvement after 3 months in Group IVIT was 22.29 (±16.147) dB, statistically showing no significant difference between the groups. Conclusion The authors recommend the use of IT steroid therapy alone in the management of SSNHL.

Objective: We investigated the incidence of sensorineural hearing loss (SNHL) after chronic otitis media (COM) surgery and determined the associated factors. Methods: Data were collected via retrospective medical chart review. Results: Of the 192 patients, 82 underwent tympanoplasty, 26 underwent canal wall up mastoidectomy with tympanoplasty, and 84 underwent canal wall down mastoidectomy with tympanoplasty. After surgery, the average air conduction (AC) hearing threshold improved significantly, from 125 to 1000 Hz, but the average high-frequency AC and bone conduction (BC) hearing thresholds deteriorated significantly. In 21 (11%) cases, the BC hearing threshold worsened by more than 15 dB at 4000 Hz. When we compared these 21 cases to patients in whom hearing was preserved, the former group was found to be significantly younger and had a higher frequency of cholesteatomatous otitis media. However, when comparing the severity of inflammation in patients with temporal bone computed tomography, there was no significant difference between the 2 groups. Conclusions: High-frequency SNHL may develop after surgery to treat COM, especially in young patients with cholesteatoma.

Objectives: To evaluate the potential origins via magnetic resonance imaging and the relevant hearing recovery course of pediatric sudden sensorineural hearing loss. Methods: We retrospectively analyzed data of 25 pediatric patients from our center with sudden sensorineural hearing loss from January 2011 to December 2016. All individuals were closely followed up at baseline and 1 and 6 months. Results: Magnetic resonance imaging identified presumed causes in 9 cases, 5 of which showed intralabyrinthine hyperintensity, suggesting presumptive intralabyrinthine hemorrhage. The remaining 20 patients showed no hyperintensity. Restoration of hearing and speech discrimination abilities were noted in these 25 children at 6 months versus the initial levels (74.2 ± 22.6 vs 93.5 ± 20.5 dB, p = .000, and 45.8 ± 36.0 vs. 18.3 ± 22.1%, p = .004, respectively). The prognosis of the individuals with intralabyrinthine hemorrhage were superior in terms of frequency and hearing threshold at 6 months compared with that of the no-hemorrhage participants. Word recognition scores improved in either studied group. Conclusion: The potential recovery of hearing in children raises concerns about very early surgical intervention within the first 6 months. Rational imaging and sequential audiometric evaluation to monitor the progression of recovery may be beneficial.
