RESUMO
BACKGROUND The dichotic digit test (DDT) is one of the tests for the behavioral assessment of central auditory processing. Dichotic listening tests are sensitive ways of assessing cortical structures, the corpus callossum, and binaural integration mechanisms, showing strong correlations with learning difficulties. The DDT is presently available in a number of languages, each appropriate for the subject's native language. However, there is presently no test in the Italian language. The goal of this study was to develop an Italian version of the one-pair dichotic digit test (DDT-IT) and analyze results in 39 normal-hearing Italian children 11 to 13 years old. We used 2 conditions of presentation: free recall and directed attention (left or right ear), and looked at possible effects of sex and ear side. MATERIAL AND METHODS This study involved 3 steps: creation of the stimuli, checking their quality with Italian speakers, and assessment of the DDT-IT in our subject pool. The study involved 39 children (26 girls and 13 boys), aged 11-13 years. All participants underwent basic audiological assessment, auditory brainstem response, and then DDT-IT. RESULTS Results under free recall and directed attention conditions were similar for right and left ears, and there were no sex or age effects. CONCLUSIONS The Italian version of DDT (DDT-IT) has been developed and its performance on 39 normal-hearing Italian children was assessed. We found there were no age or sex effects for either the free recall condition or the directed attention condition.

PURPOSE: To study outcome after cochlear implantation using the Cochlear Implant (CI) outcome assessment protocol based on the International Classification of Functioning, Disability and Health (ICF) model (CI-ICF). METHODS: Raw data of a prospective, longitudinal, multicenter study was analyzed. Seventy-two CI candidates were assessed preoperatively and six months postoperatively using the CI-ICF protocol. Following tools were used: (1) Work Rehabilitation Questionnaire (WORQ), (2) Abbreviated Profile of Hearing Aid Benefit (APHAB), (3) Audio Processor Satisfaction Questionnaire (APSQ), (4) Speech, Spatial, and Qualities of Hearing Scale (SSQ12), (5) Hearing Implant Sound Quality Index (HISQUI19), (6) Nijmegen CI Questionnaire (NCIQ) (7) pure tone audiometry, (8) speech audiometry, (9) sound localization. RESULTS: There was a significant improvement of speech discrimination in quiet (p = 0.015; p < 0.001) and in noise (p = 0.041; p < 0.001), sound detection (p < 0.001), tinnitus (p = 0.026), listening (p < 0.001), communicating with-receiving-spoken messages (p < 0.001), conversation (p < 0.001), family relationships (p < 0.001), community life (p = 0.019), NCIQ total score and all subdomain scores (p < 0.001). Subjective sound localization significantly improved (p < 0.001), while psychometric sound localization did not. There was no significant subjective deterioration of vestibular functioning and no substantial change in sound aversiveness. CI users reported a high level of implant satisfaction postoperatively. CONCLUSION: This study highlights the positive impact of cochlear implantation on auditory performance, communication, and subjective well-being. The CI-ICF protocol provides a holistic and comprehensive view of the evolution of CI outcomes.

BACKGROUND Learning to read and write depends on the effective functioning of various sensory systems, including the auditory system. Auditory information processing involves behavioral and electrophysiological processes. Electrophysiological procedures are used to investigate activity in the auditory pathway in response to sound stimuli, and the associated cortical activity in discrimination, integration, and attention. The study evaluated electrophysiological testing for an auditory processing disorder and reading performance in 54 school students aged between 8 and 12 years. MATERIAL AND METHODS The study involved 54 public school students aged between 8 and 12 years, who were divided into a study group and control group. All children underwent basic audiological assessment, rating of reading and writing ability, non-verbal intelligence, auditory brainstem response, long-latency auditory-evoked potentials (LLAEP), frequency following responses (FFR), and auditory training (AT). RESULTS The basic audiological evaluation showed a statistically significant difference between groups only for the frequency of 6 kHz. The LLAEP response had a statistically significant difference between groups for N1 latency, P300 latency, and amplitude. Finally, there was a statistically significant difference between pre-AT and post-AT to LLAEP for latencies of P2, N2, and P300 and amplitudes of N2 and P300, and to FFR for latency of wave C. CONCLUSIONS This study showed that electrophysiological tests are sensitive tools for identifying deficits in the auditory pathway. Moreover, latency measures can detect improvements from an auditory training program. In this way, an auditory intervention program might help children with reading and writing difficulties.

PURPOSE: To determine hearing preservation and subjective benefit after cochlear implant (CI) surgery in patients with low frequency hearing in the ear to be implanted (i.e., they have partial deafness, PD) and close to normal hearing in the other. METHODS: There were two study groups. The test group was made up of 12 adult patients (mean age 43.4 years; SD 13.6) with normal hearing or mild hearing loss in one ear, and with PD in the ear to be implanted. The reference group consisted of 12 adult patients (mean age 44.5 years; SD 14.1) who had PD in both ears and who underwent unilateral implantation in their worse ear. Hearing preservation was assessed 1 and 14 months after CI surgery using the Skarzynski Hearing Preservation Classification System. The APHAB questionnaire was used to evaluate the benefit from the CI. RESULTS: The differences in HP% between the groups were not significant: mean hearing preservation (HP%) in the test group was 82% one month after CI surgery and 75% some 14 months after implantation; corresponding results in the reference group were 71% and 69%. However, on the APHAB background noise subscale, the benefit in the test group was significantly larger than in the reference group. CONCLUSION: To a large extent it was possible to preserve low-frequency hearing in the implanted ear. This means that individuals with low frequency hearing in the implanted ear (partial deafness) and with normal hearing in the other generally received more benefits from cochlear implantation than did patients with partial deafness in both ears. We conclude that residual low frequency hearing in the ear to be implanted should not be considered a contraindication for a CI in a patient with single-sided deafness.

INTRODUCTION: The Vibrant Soundbridge (VSB) is a semi-implantable hearing aid for patients with various types of hearing loss and has been available for over 25 years. Recently, new audio processors with advanced signal processing, noise reduction, and multi-microphone technology have appeared. The aim of this study is to compare the benefits of using the newest Samba 2 processor to the previous generation processors in a group of experienced VSB users. METHODS: There were 22 experienced VSB users (mean time of using VSB was 9 years, SD = 2) who had their processor (D404 or Amadé) upgraded to the newest model (Samba 2). The mean age of the subjects was 56 years (SD = 20). Assessments were made by free-field audiometry, speech reception in quiet and noise, and Patient-Reported Outcome Measures (PROMs). RESULTS: Hearing tests in free field showed statistically significant improvements in hearing sensitivity and speech discrimination in quiet and noise with the Samba 2 audio processor compared to the earlier technology. PROMs confirmed the benefits of using the newest audio processor and there was more satisfaction in terms of usability. CONCLUSIONS: Access to modern technology for VSB patients provides measurable benefits.

INTRODUCTION: The main determinant in deciding on stapes surgery in patients with otosclerosis is the degree of hearing loss, specifically the size of the preoperative air-bone gap (ABG). The debate over the minimum ABG centers on the risk-to-benefit ratio of stapes surgery in patients with small ABG (sABG). The aim of this study was to measure the audiological outcomes and self-assessed satisfaction in a group of otosclerosis patients with an sABG who underwent stapedotomy. METHODS: There were 83 patients with preoperative sABG ≤25 dB HL (mean of 500, 1,000, 2,000, 4,000 Hz) included in this study. Audiometry was performed before surgery and 6 months and 12-36 months after surgery. Self-reported patient outcomes before and after surgery were collected using questionnaires. RESULTS: At the 6-month follow-up, the ABG was closed within 10 dB in 63 (78.8%) cases. Preoperatively, tinnitus was present in 70% of patients, of which 66% reported that tinnitus was a moderate or severe problem. Postoperatively, 71% of patients experienced a significant reduction in tinnitus severity and 34% of them reported complete disappearance. The self-report outcomes relating to quality of life and hearing reflected a good level of satisfaction in most patients. CONCLUSION: The possibility of reducing bothersome tinnitus after stapes surgery, and thus improving the patient's quality of life, should be taken into account when making a decision on stapes surgery in these patients.

Changes in central auditory processing due to aging in normal-hearing elderly patients, as well as age-related hearing loss, are often associated with difficulties in speech processing, especially in unfavorable acoustic environments. Speech processing depends on the perception of temporal and spectral features, and for this reason can be assessed by recordings of phase-locked neural activity when synchronized to transient and periodic sound stimuli frequency-following responses (FFRs). An electronic search of the PubMed and Web of Science databases was carried out in July 2019. Studies that evaluated the effects of age-related hearing loss on components of FFRs were included. Studies that were not in English, studies performed on animals, studies with cochlear implant users, literature reviews, letters to the editor, and case studies were excluded. Our search yielded 6 studies, each of which included 30 to 94 subjects aged between 18 and 80 years. Latency increases and significant amplitude reduction of the onset, offset, and sloop V/A components of FFRs were observed. Latency and amplitude impairment of the fundamental frequency, first formant, and high formants were related to peripheral sensorineural hearing loss in the elderly population. Conclusions: Temporal changes in FFR tracing were related to the aging process. Hearing loss also impacts the envelope fine structure, producing poorer speech comprehension in noisy environments. More research is needed to understand aspects related to hearing loss and cognitive aspects common to the elderly.

BACKGROUND Auditory brainstem response (ABR) potential is important for audiological diagnosis, reflecting the integrity of the structures of the auditory system up to the brainstem. The click stimulus is the best known and is most used in clinical practice. However, different devices and examiners may yield distinct results, and each institution tends to use its own parameters. We aimed to analyze the latency values of wave I, III, V, and interpeak intervals I-III, III-V, I-V values obtained in assessing ABR using a new device. MATERIAL AND METHODS We performed a cross-sectional study of 73 participants with normal hearing thresholds and no hearing problems. All underwent basic audiological (air and bone conduction, Speech Recognition Threshold, Speech Recognition Index, acoustic reflex, and tympanometry) and electrophysiological evaluation (ABR assessment). RESULTS Absolute latency and interpeak values from ABR showed earlier responses in women, faster than international standards suggest. The responses were similar to other studies carried out previously, with the exception of wave I values, which were a little earlier in females. CONCLUSIONS We assessed normative data from measurement of latency values of wave I, III, V, and interpeak intervals I-III, III-V, and I-V applying 2 standard deviations in the assessment of ABR using the new Neuro-Audio/ABR device created by Neurosoft.

PURPOSE: The purpose of the study was to validate the AQoL-8D questionnaire in the adult population of patients referred to an otolaryngology clinic. METHODS: AQoL-8D was translated into Polish. 463 patients (age18-80 years) with otolaryngological conditions were assessed with the AQoL-8D, SF-6D, and SWLS questionnaires. We investigated the item content-relevance, factor structure by means of Confirmatory Factor Analysis, corrected item-total correlations, Cronbach's alpha, Pearson correlation of the AQoL-8D scores with results from SF-6D and from the SWLS questionnaires. Finally, ANOVA was used to test the AQoL-8D ability to group the HRQoL of patients in terms of their otolaryngological management type. RESULTS: The median score of item content-relevance was 5.0 for all AQoL-8D items. Confirmatory Factor Analysis revealed the following fit indices: Comparative Fit Index = 0.81; Tucker-Lewis Index = 0.80; and Root Mean Square Error of Approximation = 0.07. Cronbach's alpha for AQoL-8D dimensions ranged from 0.48 to 0.79. Mean item-total correlations over all dimensions, super dimensions, and the instrument overall were higher than 0.3. There was a significant Pearson correlation between the results obtained with AQoL-8D and SF-6D (r = 0.68), and with AQoL-8D and SWLS (r = 0.43). A one-way ANOVA showed a significant effect of management type on HRQoL as measured by AQoL-8D [F(4,458) = 6.12, p < 0.001] CONCLUSION: AQoL-8D provides valid and reliable measures of HRQoL in patients undergoing otolaryngological treatment. Because it is a generic questionnaire, it is possible to make general comparisons of otolaryngology outcomes with those from other subspecialties.

PURPOSE: To gauge the benefits to children of upgrading speech processors during the COVID-19 pandemic. METHODS: The study involved 297 children, aged from 7.3 to 18.0 years, whose processors were upgraded to either Nucleus 7 or Kanso 2, or to Sonnet 2 or Rondo 3. To document the benefits of the upgrades, a speech-in-noise discrimination test and Patient Reported Outcome Measures (PROMs) were used. RESULTS: There was a significant benefit from the newer processors in terms of speech discrimination in noise. Patient Reported Outcome Measures (PROMs) indicated less hearing disability, a higher level of functioning in everyday life situations, and more satisfaction with the new speech processor in social situations. CONCLUSION: There is a measurable improvement in performance when the devices are upgraded to the new technology.

PURPOSE: To demonstrate the feasibility of upgrading speech processors during the COVID-19 pandemic. METHODS: Adopting concepts from "lean thinking", we optimized hospital workflows to allow speech processors to be upgraded despite the obstacles arising from national guidelines for COVID-19 prevention. The study involved 297 children, aged from 7.3 to 18.0 years, whose processors were upgraded on five consecutive Saturdays during a time of peak COVID-19 in Poland. RESULTS: The optimized workflow allowed us to conduct speech processor upgrades during a time of peak COVID-19 in Poland. The upgrades were conducted as scheduled, patient flow was smooth, appropriate social distancing was kept, and no reports of COVID-19 infection in our patients in the 2 weeks after their visit were received. CONCLUSION: Upgrading of speech processors in children is still feasible under coronavirus conditions.

BACKGROUND: The World Health Organization reports that the number of tinnitus sufferers is increasing year on year. Given the common use of mobile devices and the availability of applications designed to support patients in tinnitus therapy and reduce tinnitus severity, patients seeking help are likely to try this form of support. The aim of this study was to evaluate the effectiveness of a mobile application in tinnitus sound therapy, in this case ReSound Tinnitus Relief™. METHODS: The study involved 52 patients hospitalized for tinnitus. All participants used the free ReSound Tinnitus Relief application for 6 months. The application is based on sound therapy. Patients were advised to use the application for at least 30 min per day, the sounds should not completely mask the tinnitus, and they should be listened to via a loudspeaker. The effects of the therapy were evaluated by means of standardized questionnaires for tinnitus severity: the Tinnitus Handicap Inventory and the Tinnitus Functional Index. RESULTS: The study showed a reduction in tinnitus severity as measured by both questionnaires. The general severity decreased after the first 3 months and again in the following 3 months of using the application. In both questionnaires the biggest changes were observed in the subscales of emotions. CONCLUSIONS: Results obtained here from standardized questionnaires indicate that the tested application may contribute to tinnitus reduction. However, it is advisable to conduct further research on the applicability of such technology in medical practice.

OBJECTIVE: Self-help (without specialist support) can play an important role in tinnitus therapy. The purpose of this study was to investigate what fraction of subjects with tinnitus use self-help, what techniques are most commonly used to reduce tinnitus severity, and what distinguishes patients that use self-help from others. DESIGN: retrospective, observational study. STUDY SAMPLE: Adult patients admitted to our hospital clinic (460 participants) aged 19-83 years and reporting chronic tinnitus. The survey concerned therapy attempts prior to the clinic visit as well as self-help techniques chosen freely by the patient to reduce tinnitus severity. RESULTS: Data showed that 40.9% of the respondents chose some action themselves to reduce their tinnitus severity. Among the reported self-help techniques, acoustic stimulation was the most popular. In addition, patients chose distraction attention, relaxation, meditation, yoga, and physical activity. The likelihood of undertaking self-help increases with better education and higher tinnitus severity. CONCLUSIONS: Knowledge about patients' preferences of forms of self-help may help the health practitioner suggest a more suitable form of therapy. Due to the great interest in using sound therapy in tinnitus, it would be worthwhile looking at new forms of this therapy, for example increasingly popular mobile applications.

INTRODUCTION: Recently, Interacoustics presented a new otoacoustic emission protocol where the probe pressurizes the ear cavity, thus eliminates the risk of non-assessment (REFER outcome) due to a negative middle ear pressure. This study evaluated the characteristics and the performance of this new protocol on a newborn well-baby population. METHODS: One hundred sixty-three newborns (age 2.7 ± 1.1 days) for a total of 294 ears were assessed randomly. Transiently evoked otoacoustic responses were acquired by the Titan device (Interacoustics), using the default and a pressurized TEOAE protocol. The data were analyzed in terms of signal to noise ratios (S/Ns) at 5 frequencies, namely, 0.87, 1.94, 2.96, 3.97, and 4.97 kHz. To assess any possible gestational age (GE) effects on the TEOAE variables, the responses were subdivided in 4 different age subgroups. RESULTS: There were no significant differences between the left and right ear TEOAE responses, for age (in days), GE (in weeks), weight (in grams), and S/N at all 5 frequencies. Considering the pooled 294 ears, paired t tests between the default and the pressurized TEOAE data showed significant differences across all 5 frequencies (p < 0.01). The pressurized protocol generated TEOAE responses presenting larger S/Ns, and a positive additive effect of approximately 2.31 dB was observed at all tested frequencies. There were no significant GE effects on the pressurized TEOAE responses. In terms of performance, both protocols performed equally (same number of PASSes). CONCLUSION: The pressurized TEOAE protocol generates responses with higher S/Ns which might be useful in borderline cases where the middle ear status might cause a REFER screening outcome.

OBJECTIVE: To compare the cognitive evolution of older adults with severe or profound hearing impairment after cochlear implantation with that of a matched group of older adults with severe hearing impairment who do not receive a cochlear implant (CI). DESIGN: In this prospective, longitudinal, controlled, and multicenter study, 24 older CI users were included in the intervention group and 24 adults without a CI in the control group. The control group matched the intervention group in terms of gender, age, formal education, cognitive functioning, and residual hearing. Assessments were made at baseline and 14 months later. Primary outcome measurements included the change in the total score on the Repeatable Battery for the Assessment of Neuropsychological Status for Hearing impaired individuals score and on its subdomain score to assess cognitive evolution in both groups. Secondary outcome measurements included self-reported changes in sound quality (Hearing Implant Sound Quality Index), self-perceived hearing disability (Speech, Spatial, and Qualities of Hearing Scale), states of anxiety and depression (Hospital Anxiety and Depression Scale), and level of negative affectivity and social inhibition (Type D questionnaire). RESULTS: Improvements of the overall cognitive functioning (p = 0.05) and the subdomain "Attention" (p = 0.02) were observed after cochlear implantation in the intervention group; their scores were compared to the corresponding scores in the control group. Significant positive effects of cochlear implantation on sound quality and self-perceived hearing outcomes were found in the intervention group. Notably, 20% fewer traits of Type D personalities were measured in the intervention group after cochlear implantation. In the control group, traits of Type D personalities increased by 13%. CONCLUSION: Intervention with a CI improved cognitive functioning (domain Attention in particular) in older adults with severe hearing impairment compared to that of the matched controls with hearing impairment without a CI. However, older CI users did not, in terms of cognition, bridge the performance gap with adults with normal hearing after 1 year of CI use. The fact that experienced, older CI users still present subnormal cognitive functioning may highlight the need for additional cognitive rehabilitation in the long term after implantation.

BACKGROUND The aim of this study was to assess the effectiveness of bone conduction hearing aids in children under 2 years old who have congenital microtia and atresia. MATERIAL AND METHODS This prospective study involved 42 children under 2 years old with congenital microtia and atresia who were divided into 2 groups: 21 with unilateral defect and 21 with bilateral defect. All children were provided with bone conduction hearing aids on a softband. Air and bone auditory thresholds were assessed by auditory brainstem responses (ABRs). The LittlEARS questionnaire was used to evaluate auditory development at baseline and after 6 months of hearing aids use. Behavioral observation audiometry (BOA) was used to assess auditory thresholds and compare aided and unaided hearing. RESULTS After 6 months of hearing aid use, the total score of the LittlEARS questionnaire in children with unilateral defect was 24±5.60, while children with bilateral defect achieved a result of 26.29±6.17. Hearing thresholds in both groups with bone conduction hearing aids improved significantly and approached the normal level. CONCLUSIONS Our results confirm that bone conduction hearing aids provide an effective method of auditory rehabilitation for children with conductive and mixed hearing loss caused by microtia and atresia. Using bone conduction hearing aids in such children is crucial for proper hearing, speech, and language development.

PURPOSE: In clinical trials and everyday medical practice, health-related quality of life (HRQoL) measures are increasingly being used. That is, in addition to the usual biological health assessment, the impact of disease and treatment on the patient's functioning in the physical, mental, and social areas is an important parameter. The aim of this study was to assess HRQoL before and after using a cochlear implant (CI) in adults with profound hearing loss. METHODS: There were 104 patients who qualified for the study. All gave informed and free consent. The study involved adults with bilateral hearing loss above 81 dB HL and rated according to the World Health Organization (WHO) classification scheme as having profound hearing loss (which includes deafness). In each participant, the hearing loss was postlingual, that is, it occurred after speech and language had developed. The assessment of quality of life (AQoL-8D) questionnaire was used to assess the health-related quality of life in the study participants. RESULTS: Quality of life significantly increased (p < 0.001) after cochlear implantation in almost all domains (except the pain dimension). The mean increase in overall quality of life was 0.16, the greatest improvement was found in the dimensions senses (mean change of 0.17) and self-worth (mean change of 0.16). CONCLUSION: Cochlear implantation improves the health-related quality of life of the postlingually deaf.

PURPOSE: To evaluate the safety and performance of three novel vibroplasty couplers that allow attachment of the floating mass transducer of a transcutaneous active middle ear implant (AMEI) to the round window (RW) membrane, the long process (LP), or the incus body and the short process (SP) of the incus. METHODS: Retrospective multicenter cohort study of 25 AMEI users with sensorineural or mixed hearing loss that were among the first implanted with an AMEI vibrating ossicular prosthesis in combination with the third generation of vibroplasty couplers between 2014 and 2016. Main Outcome Measures were bone-conduction pure-tone and vibroplasty thresholds, postoperative aided sound field thresholds and postoperative aided word recognition score (WRS). RESULTS: Bone conduction threshold changes of more than 10 dB in 4PTABC were observed in two subjects. A mean improvement of 57.8% in speech recognition was observed with a mean WRS at 65 dB SPL improving from 14.8% (SD 21.9%) preoperatively to a mean aided score of 72.6% (SD 18.6%). Sound field thresholds improved from an average 4PTASF of 64.1 dB HL (SD 9.8 dB HL) to 37.0 dB HL (SD 8.9 dB HL), resulting in a mean functional gain of 27.1 dB. There was no significant difference in WRS or functional gain between the coupler types. CONCLUSION: Initial experience shows that all three third generation vibroplasty couplers represent safe and efficient attachment options for the FMT allowing the surgeon to choose the coupling type based on the present pathology.

OBJECTIVE: The purpose of the study was to determine the reliability in children of the medial olivocochlear reflex when measured as decibels of suppression of transiently evoked otoacoustic emissions (TEOAEs) by contralateral acoustic stimulation (CAS). DESIGN: TEOAEs with and without CAS (white noise) were measured. In each subject, measurements were performed twice. Of particular interest was the suppression of TEOAEs by CAS and its reliability. Reliability was evaluated by calculating the standard error of measurement (SEM) and minimum detectable change (MDC). STUDY SAMPLE: Fifty-one normally hearing girls aged 3-6 years. RESULTS: The average global TEOAE suppression was around 0.6 dB. The highest reliability was for global values, with SEM of 0.2 dB and MDC of ±0.55 dB for the standard 2.5-20 ms recording window and slightly higher values for an 8-18 ms window. The worst reliability in the studied group was for the 1 kHz half-octave frequency band. Additionally, ears without spontaneous otoacoustic emissions had higher suppression levels than those with, but they also had lower signal-to-noise ratios, which may limit their clinical utility. CONCLUSIONS: The current study shows that, under the studied paradigm, TEOAE suppression does not have satisfactory reliability since MDC was similar to the level of suppression.

BACKGROUND A prospective clinical study was conducted to assess different regimens of steroid therapy and preservation of hearing following cochlear implantation. MATERIAL AND METHODS Study participants were ≥18 years-of-age, with a cochlear duct length ≥27.1 mm measured by computed tomography (CT), with hearing sound levels in the range of 10-120 decibels (dB) and sound frequencies of 125-250 hertz (Hz); sound levels of 35-120 dB and frequencies of 500-1,000 Hz; sound levels of 75-120 dB and frequencies of 2,000-8,000 Hz. Study exclusion criteria included diseases with contraindications for steroid therapy or medications that increased the effects of steroids. Patients had cochlear implantation and were divided into three treatment groups: intravenous (IV) steroid therapy (standard steroid therapy): combined oral and IV steroid therapy (prolonged steroid therapy); and a control group (cochlear implantation without steroid therapy). Hearing preservation was established by pure tone audiometry based on the pre-operative and postoperative average hearing thresholds according to the formula developed by the HEARRING Network. RESULTS There were 36 patients included in the study. In all cases, the cochlear implant electrode was inserted via the round window approach with a straight electrode length of 28 mm. Patients with combined oral and IV steroid therapy (prolonged steroid therapy) had better results when compared with patients with intravenous (IV) steroid therapy (standard steroid therapy) and the control group. CONCLUSIONS Prolonged steroid therapy using combined oral and IV steroids stabilized hearing thresholds and preserved hearing in adult patients following cochlear implantation.
