Clinical Verification of Ear Level FM Systems: Classroom & Personal Use Applications

Dave Smriga: In today’s course, we’ll explore how Audioscan equipment easily facilitates the execution of the most current recommended FM verification procedures. In addition, we’ll discuss how you can use these procedures for both FM system verification and verification of remote microphone technology. Although we will be depicting the various test procedures included in today's webinar with images created using the Verifit2 hearing instrument fitting system, the same tests can be performed with the original Verifit system.

The Ponto Bone Anchored System: The Right Choice for Pediatrics

Today, I will begin with the fundamentals of bone anchored technology including an overview of osseointegration, and that will give us the foundation to discuss patient candidacy as well as surgical and fitting considerations. I will review Ponto practicalities, such as how the processor was designed to be durable and reliable – which is especially important when we fit children. I will talk about the signal processing in the Ponto processors and present evidence that supports how it benefits our youngest bone anchored patients. When fitting children with amplification, what is the goal?

Comparing Distortion Product Otoacoustic Emissions to Intracochlear Distortion Products Inferred from a Noninvasive Assay

Abstract

The behavior of intracochlear distortion products (iDPs) was inferred by interacting a probe tone (f₃) with the iDP of interest to produce a “secondary” distortion product otoacoustic emission termed DPOAE^2ry. Measures of the DPOAE^2ry were then used to deduce the properties of the iDP. This approach was used in alert rabbits and anesthetized gerbils to compare ear-canal 2f₁-f₂ and 2f₂-f₁ DPOAE f₂/f₁ ratio functions, level/phase (L/P) maps, and interference-response areas (IRAs) to their simultaneously collected DPOAE^2ry counterparts. These same measures were also collected in a human volunteer to demonstrate similarities with their laboratory animal counterparts and their potential applicability to humans. Results showed that DPOAEs and inferred iDPs evidenced distinct behaviors and properties. That is, DPOAE ratio functions elicited by low-level primaries peaked around an f₂/f₁ = 1.21 or 1.25, depending on species, while the corresponding inferred iDP ratio functions peaked at f₂/f₁ ratios of ~1. Additionally, L/P maps showed rapid phase variation with DPOAE frequency (f_dp) for the narrow-ratio 2f₁-f₂ and all 2f₂-f₁ DPOAEs, while the corresponding DPOAE^2ry measures evidenced relatively constant phases. Common features of narrow-ratio DPOAE IRAs, such as large enhancements for interference tones (ITs) presented above f₂, were not present in DPOAE^2ry IRAs. Finally, based on prior experiments in gerbils, the behavior of the iDP directly measured in intracochlear pressure was compared to the iDP inferred from the DPOAE^2ry and found to be similar. Together, these findings are consistent with the notion that under certain conditions, ear-canal DPOAEs provide poor representations of iDPs and thus support a “beamforming” hypothesis. According to this concept, distributed emission components directed toward the ear canal from the f₂ and basal to f₂ regions can be of differing phases and thus cancel, while these same components directed toward f_dp add in phase.

Direction-reversing Nystagmus in Horizontal and Posterior Semicircular Canal Canalolithiasis.

Objectives: To investigate the incidence and characteristics of direction-reversing nystagmus in patients with horizontal (HSCC) and posterior semicircular canal (PSCC) canalolithiasis, and evaluate the effect of direction-reversing nystagmus on the treatment outcome. Study Design: A retrospective study. Methods: Between March 2014 and September 2015, 63 and 92 consecutive patients with HSCC and PSCC canalolithiasis, respectively, were enrolled. Positional nystagmus characteristics were examined using video-nystagmography. Results: In HSCC canalolithiasis, direction-reversing nystagmus was observed in 73% of patients (46 of 63), of which 19 cases were bilateral and 27 unilateral. In patients with bilateral reversal, maximal slow-phase velocity (mSPV) was significantly greater when the head turned to the lesioned side than to the healthy side in both the first and second phase. In all patients with unilateral reversal, direction-reversing nystagmus always occurred in the side of stronger initial nystagmus in a supine roll test. The mean mSPV of first phase nystagmus was significantly greater on the side with reversal than without (p

The Effect of Simulated Mastoid Obliteration on the Mechanical Output of Electromagnetic Transducers.

Background: The electromagnetic transducers of implantable middle ear hearing devices or direct acoustic cochlear implants (DACIs) are intended for implantation in an air-filled middle ear cavity. When implanted in an obliterated radical mastoid cavity, they would be surrounded by fatty tissue of unknown elastic properties, potentially attenuating the mechanical output. Here, the elastic properties of this tissue were determined experimentally and the vibrational output of commonly used electromagnetic transducers in an obliterated radical mastoid cavity was investigated in vitro using a newly developed method. Methods: The Young's moduli of human fatty tissue samples (3-mm diameter), taken fresh from the abdomen or from the radical mastoid cavity during revision surgeries, were determined by indentation tests. Two phantom materials having Young's moduli similar to and higher than (worst case scenario) the tissue were identified. The displacement output of a DACI, a middle ear transducer (MET) and a floating mass transducer (FMT), was measured when embedded in the phantom materials in a model radical cavity and compared with the output of the nonembedded transducers. Results: The here-determined Young's moduli of fresh human abdominal fatty tissue were comparable to the moduli of human breast fat tissue. When embedded in the phantom materials, the displacement output amplitude at 0.1 to 10 kHz of the DACI and MET was attenuated by maximally 5 dB. The attenuation of the output of the FMT was also minor at 0.5 to 10 kHz, but significantly reduced by up to 35 dB at lower frequencies. Conclusion: Using the method developed here, the Young's moduli of small soft tissue samples could be estimated and the effect of obliteration on the mechanical output of electromagnetic transducers was investigated in vitro. Our results demonstrate that the decrease in vibrational output of the DACI and MET in obliterated mastoid cavities is expected to be minor, having no major impact on clinical indication. Although no major attenuation of vibrational output of the FMT was found for frequencies >0.5 kHz, for implantations in patients the attenuation at frequencies

Surgical Anatomy of the Human Round Window Region: Implication for Cochlear Endoscopy Through the External Auditory Canal.

Objective: To enable development of an endoscope for cellular-level optical imaging of the inner ear. Study Design: A prospective study of 50 cadaveric human temporal bones to define detailed surgical anatomy of the round window (RW) region and the range of angles necessary to reach the RW membrane perpendicularly via the external ear canal. Main Outcome Measure: The transcanal angle to the RW membrane was surgically measured in 3D intact specimens, and correlated with the angle calculated from temporal bone computed tomography (CT) scans of the same specimens obtained before and after measurements in situ. Results: Surgically measured transcanal angles to the RW membrane correlated well with the radiographically measured angles. The angles ranged from 110 to 127 degrees, with the median of 115 degrees and the middle 50% ranging from 109 to 119 degrees. Four temporal bones were excluded because of pathology. The opening of the RW niche was located posteriorly in six bones (13%), inferiorly in 18 bones (39%), and postero-inferiorly in 22 bones (48%). The angles were not statistically different among the three orientations of the RW niche. Conclusions: By correlating measurement from cadaveric human temporal bones and their CT scans, we defined key parameters necessary for designing an endoscope for intracochlear imaging using a minimally invasive approach through the external auditory canal. The excellent correlation between the measurement on the CT scan and the actual shape of the probe that was able to reach the RW through the ear canal enables selection of the probe using the CT data.

Using Balance Function to Screen for Vestibular Impairment in Children With Sensorineural Hearing Loss and Cochlear Implants.

Objectives: 1) To determine if bilateral vestibular dysfunction can be predicted by performance on standardized balance tasks in children with sensorineural hearing loss (SNHL) and cochlear implants (CI). 2) To provide clinical recommendations for screening for vestibular impairment in children with SNHL. Study Design: Retrospective cohort study. Setting: Tertiary care pediatric implant center. Patients: Pediatric patients (4.8-18.6 years) with profound SNHL using CIs. Interventions: Vestibular end-organ (horizontal canal and otoliths), and balance assessment. Main Outcome Measures: Comparison of balance skills, measured by the Bruininks Oseretsky Test of Motor Proficiency II (BOT-2), was performed between two groups of children with SNHL and CI: 1) total bilateral vestibular loss (TBVL) (n = 45), and 2) normal bilateral vestibular function (n = 20). Sensitivity, specificity, and suitability of each task as a screening tool for the detection of TBVL were assessed. Results: Balance as measured by the BOT-2 balance subtest was significantly poorer in children with TBVL then those with normal vestibular function (p

Participant-generated Cochlear Implant Programs: Speech Recognition, Sound Quality, and Satisfaction.

Objective: To determine whether patient-derived programming of one's cochlear implant (CI) stimulation levels may affect performance outcomes. Background: Increases in patient population, device complexity, outcome expectations, and clinician responsibility have demonstrated the necessity for improved clinical efficiency. Methods: Eighteen postlingually deafened adult CI recipients (mean = 53 years; range, 24-83 years) participated in a repeated-measures, within-participant study designed to compare their baseline listening program to an experimental program they created. Results: No significant group differences in aided sound-field thresholds, monosyllabic word recognition, speech understanding in quiet, speech understanding in noise, nor spectral modulation detection (SMD) were observed (p > 0.05). Four ears (17%) improved with the experimental program for speech presented at 45 dB SPL and two ears (9%) performed worse. Six ears (27.3%) improved significantly with the self-fit program at +10 dB signal-to-noise ratio (SNR) and four ears (26.6%) improved in speech understanding at +5 dB SNR. No individual scored significantly worse when speech was presented in quiet at 60 dB SPL or in any of the noise conditions tested. All but one participant opted to keep at least one of the self-fitting programs at the completion of this study. Participants viewed the process of creating their program more favorably (t = 2.11, p = 0.012) and thought creating the program was easier than the traditional fitting methodology (t = 2.12, p = 0.003). Average time to create the self-fit program was 10 minutes, 10 seconds (mean = 9:22; range, 4:46-24:40). Conclusions: Allowing experienced adult CI recipients to set their own stimulation levels without clinical guidance is not detrimental to success. Copyright (C) 2016 by Otology & Neurotology, Inc.

Long-term Follow-up Study of the Sandwich Cartilage Shoe Technique in Cases of Insecure Stapes Footplate.

Objective: Analysis of the audiometric results after repair of a defective footplate with the sandwich cartilage shoe technique in a follow-up study. Study Design: Retrospective analysis of audiometric data. Setting: Hospital. Patients: The cohort consisted of 12 patients, who underwent ossicular reconstruction after sandwich cartilage shoe technique in a case of insecure stapes footplate. The mean age was 42.7 years with an equal sex distribution. In every patient, cholesteatoma was the reason for surgery with 75% being revision cases. Intervention: Sandwich cartilage shoe technique in case of insecure stapes footplate at the department of otorhinolaryngology, head and neck surgery at the University of Cologne over an 8-year period (2007-2015). Main Outcome Measure: The use of the "sandwich cartilage shoe technique" in case of a broken or unstable footplate allows a safe occlusion of the open vestibule. Results: The statistical analysis revealed a significant improvement of the pure-tone average (p = 0.011) and air-bone gap (ABG) (p = 0.016) after total ossicular replacement prosthesis (TORP) implantation. The hearing was stable at 9 months of follow up. Conclusion: The sandwich cartilage shoe technique offers a safe and effective option as a two-stage procedure in treating patients with fractures of the stapes footplate in case of chronic otitis media. In view of the possible risk of deafness going along with a destruction of an inner ear window, our results can be considered substantial as all our patients will at least be able to regain "social hearing" as they all either achieved a hearing threshold is less than 30 dB or can be sufficiently supplied with a conventional hearing aid.

Characteristics and Spontaneous Recovery of Tinnitus Related to Idiopathic Sudden Sensorineural Hearing Loss.

Objective: To evaluate the characteristics and spontaneous recovery of tinnitus related to idiopathic sudden sensorineural hearing loss (ISSNHL). Study Design: Retrospective analysis from two randomized placebo-controlled clinical trials for treatment of ISSNHL within 48 hours from onset (Study A), or of tinnitus related to ISSNHL within 3 months from onset (Study B). Setting: Forty-eight European sites (academic tertiary referral centers, private ENT practices). Patients: One hundred thirteen adult patients of which 65 with hearing loss >=30 dB (Study A) and 48 with persistent acute tinnitus (Study B) at baseline. Interventions: Intratympanic (i.t.) injection of placebo gel in single dose or in triple dose during 3 consecutive days. Main Outcome Measures: Frequency of tinnitus, subjective tinnitus loudness, rates of complete tinnitus remission, and complete hearing recovery during 3 months follow-up. Results: In acute ISSNHL, tinnitus loudness decreased rapidly in cases of mild-moderate hearing loss, and tinnitus had completely resolved in two-thirds of patients after 3 months. Hearing recovery preceded tinnitus resolution. When associated with severe-profound hearing loss, tinnitus improved significantly less. Complete hearing recovery and full tinnitus remission were both about three times more frequent in mild-moderate hearing loss patients than in severe-profound cases. Improvement in tinnitus loudness over time can be approximated by a negative exponential function. Conclusions: Prognosis for ISSNHL-related tinnitus is relatively poor in case of severe-profound hearing loss and the longer it has persisted. Alleviation or management of tinnitus should be a key therapeutic objective especially in pronounced ISSNHL cases.

Symbolic Play and Novel Noun Learning in Deaf and Hearing Children: Longitudinal Effects of Access to Sound on Early Precursors of Language

by Alexandra L. Quittner, Ivette Cejas, Nae-Yuh Wang, John K. Niparko, David H. Barker

In the largest, longitudinal study of young, deaf children before and three years after cochlear implantation, we compared symbolic play and novel noun learning to age-matched hearing peers. Participants were 180 children from six cochlear implant centers and 96 hearing children. Symbolic play was measured during five minutes of videotaped, structured solitary play. Play was coded as "symbolic" if the child used substitution (e.g., a wooden block as a bed). Novel noun learning was measured in 10 trials using a novel object and a distractor. Cochlear implant vs. normal hearing children were delayed in their use of symbolic play, however, those implanted before vs. after age two performed significantly better. Children with cochlear implants were also delayed in novel noun learning (median delay 1.54 years), with minimal evidence of catch-up growth. Quality of parent-child interactions was positively related to performance on the novel noun learning, but not symbolic play task. Early implantation was beneficial for both achievement of symbolic play and novel noun learning. Further, maternal sensitivity and linguistic stimulation by parents positively affected noun learning skills, although children with cochlear implants still lagged in comparison to hearing peers.

Accuracy and Repeatability of two methods of gait analysis − GaitRite™ und Mobility Lab™ − in subjects with cerebellar ataxia

Instrumental gait analysis is increasingly recognized as a useful tool for the evaluation of movement disorders. The various assessment devices available to date have mostly been evaluated in healthy populations only. We aimed to explore whether reliability and validity seen in healthy subjects can also be assumed in subjects with cerebellar ataxic gait. Gait was recorded simultaneously with two devices − a sensor-embedded walkway and an inertial sensor based system − to explore test accuracy in two groups of subjects: one with mild to moderate cerebellar ataxia due to a subtype of autosomal-dominantly inherited neurodegenerative disorder (SCA14), the other were healthy subjects matched for age and height (CTR). Test precision was assessed by retest within session for each device. In conclusion, accuracy and repeatability of gait measurements were not compromised by ataxic gait disorder. The accuracy of spatial measures was speed-dependent and a direct comparison of stride length from both devices will be most reliably made at comfortable speed. Measures of stride variability had low agreement between methods in CTR and at retest in both groups. However, the marked increase of stride variability in ataxia outweighs the observed amount of imprecision.

Lexically driven selective adaptation by ambiguous auditory stimuli occurs after limited exposure to adaptors

Limited exposure to ambiguous auditory stimuli results in perceptual recalibration. When unambiguous stimuli are used instead, selective adaptation (SA) effects have been reported, even after few adaptor presentations. Crucially, selective adaptation by an ambiguous sound in biasing lexical contexts had previously been found only after massive adaptor repetition [Samuel (2001). Psychol. Sci. 12(4), 348–351]. The present study shows that extensive exposure is not necessary for lexically driven selective adaptation to occur. Lexically driven selective adaptation can arise after as few as nine adaptor presentations. Additionally, build-up course inspection reveals several parallelisms with the time course observed for SA with unambiguous stimuli.

Does clinician continuity influence hearing aid outcomes?

Does clinician continuity influence hearing aid outcomes?

Int J Audiol. 2016 May 25;:1-8

Authors: Bennett RJ, Meyer C, Eikelboom RH

Abstract
OBJECTIVE: To evaluate whether clinician continuity is associated with successful hearing aid outcomes.
DESIGN: A prospective cohort study. Clinician continuity was defined as occurring when a patient was cared for by the same clinician for the hearing assessment, hearing aid selection process, hearing aid fitting and programming, and subsequent hearing aid fine tuning appointments. The hearing aid outcome measures included self-reported hearing aid use, benefit and satisfaction as well as self-reported handling skills and problems experienced with hearing aids.
STUDY SAMPLE: Four hundred and sixty-eight adult hearing aid users (mean age 73.9 years ±10.9) and 26 qualified audiologists (mean age 34 years ±6.34) recruited from a single hearing clinic in Perth, Western Australia.
RESULTS: There were no significant differences in hearing aid outcomes between participants who experienced clinician continuity and those who did not.
CONCLUSIONS: Within a controlled practice setting, hearing aid outcomes may not be adversely effected if services are provided by more than one clinician.

RESULTS: There were no significant differences in hearing aid outcomes between participants who experienced clinician continuity and those who did not.
CONCLUSIONS: Within a controlled practice setting, hearing aid outcomes may not be adversely effected if services are provided by more than one clinician.

Does clinician continuity influence hearing aid outcomes?

Does clinician continuity influence hearing aid outcomes?

Int J Audiol. 2016 May 25;:1-8

Authors: Bennett RJ, Meyer C, Eikelboom RH

Abstract
OBJECTIVE: To evaluate whether clinician continuity is associated with successful hearing aid outcomes.
DESIGN: A prospective cohort study. Clinician continuity was defined as occurring when a patient was cared for by the same clinician for the hearing assessment, hearing aid selection process, hearing aid fitting and programming, and subsequent hearing aid fine tuning appointments. The hearing aid outcome measures included self-reported hearing aid use, benefit and satisfaction as well as self-reported handling skills and problems experienced with hearing aids.
STUDY SAMPLE: Four hundred and sixty-eight adult hearing aid users (mean age 73.9 years ±10.9) and 26 qualified audiologists (mean age 34 years ±6.34) recruited from a single hearing clinic in Perth, Western Australia.
RESULTS: There were no significant differences in hearing aid outcomes between participants who experienced clinician continuity and those who did not.
CONCLUSIONS: Within a controlled practice setting, hearing aid outcomes may not be adversely effected if services are provided by more than one clinician.

Deaf Adolescents' Learning of Cardiovascular Health Information: Sources and Access Challenges.

J Deaf Stud Deaf Educ. 2015 Oct;20(4):408-18

Authors: Smith SR, Kushalnagar P, Hauser PC

Abstract
Deaf individuals have more cardiovascular risks than the general population that are believed to be related to their cardiovascular health knowledge disparities. This phenomenological study describes where 20 deaf sign language-using adolescents from Rochester, New York, many who possess many positive characteristics to support their health literacy, learn cardiovascular health information and their lived experiences accessing health information. The goal is to ultimately use this information to improve the delivery of cardiovascular health education to this population and other deaf adolescents at a higher risk for weak health literacy. Deaf bilingual researchers interviewed deaf adolescents, transcribed and coded the data, and described the findings. Five major sources of cardiovascular health information were identified including family, health education teachers, healthcare providers, printed materials, and informal sources. Despite possessing advantageous characteristics contributing to stronger health literacy, study participants described significant challenges with accessing health information from each source. They also demonstrated inconsistencies in their cardiovascular health knowledge, especially regarding heart attack, stroke, and cholesterol. These findings suggest a great need for additional public funding to research deaf adolescents' informal health-related learning, develop accessible and culturally appropriate health surveys and health education programming, improve interpreter education, and disseminate information through social media.

Prognostic and Evolutive Factors of Tinnitus Triggered by Sudden Sensorineural Hearing Loss.

Introduction: The association between sudden sensorineural hearing loss (SSNHL) and tinnitus is frequent. Its correlation with the auditory prognosis remains controversial. The objective of the study is to evaluate tinnitus of which onset is concurrent with SSNHL and analyze it as a prognostic factor and its correlation with hearing recovery. Materials and Methods: A prospective cohort study was conducted with 30 patients with SSNHL. Serial audiometry was performed and the Tinnitus Handicap Inventory (THI) was applied at the initial consultation and after treatment. Results: Tinnitus had an incidence of 93.3%, with an initial mean THI of 63.6%. The mean decrease in THI was significant in all scale domains. However, there was no statistically significant difference between the degrees of tinnitus and hearing loss, as well as between hearing recovery percentage in relation to the degree of tinnitus. The correlation of THI gain with the hearing recovery rate was negative (the greater the decrease in the level of tinnitus discomfort, the greater the hearing recovery rate), being significant only in the emotional domain of THI, but showing a poor correlation. Discussion: There was a reduction in the level of tinnitus discomfort, as measured by THI, after treatment of SSNHL. There is a correlation between tinnitus and hearing improvement in patients with SSNHL only in the emotional domain of THI, but this correlation is considered poor. The degree of tinnitus severity as measured by THI was not proportional to the hearing loss and is not a prognostic factor for hearing improvement. Copyright (C) 2016 by Otology & Neurotology, Inc.

Functional Testing of Subcutaneous Piezoelectrically Actuated Hearing Aid: Comparison With BAHA and Potential for Treating Single-sided Deafness.

Objective: To compare the performance of a subcutaneous piezoelectrically actuated hearing aid (SPAHA) with the bone-anchored hearing aid (BAHA) and assess its effectiveness as a treatment option for conductive loss and single-sided deafness (SSD). Background: To validate the use of the SPAHA as a bone conduction implant, its performance was compared with a widely used bone conduction implant, the BAHA. Maximum dynamic range, power consumed to deliver standard speech signals and total harmonic distortion (THD) was assessed. The transcranial attenuation was also measured to assess the SPAHA's potential to treat SSD. Method: Functional testing of the SPAHA and BAHA was conducted using cadaver heads. Ipsilateral and contralateral promontory velocity and the power consumption by the devices were measured at 111 different frequencies in the range of 200 to 9600 Hz. Performance metrics were derived from these measurements. Result: The maximum dynamic range for SPAHA was within 10 dB of that of BAHA. The THD for the SPAHA was at most 3%, slightly better than the BAHA. The power consumption by the SPAHA, whereas highly variable, was not statistically different than that of the BAHA. Transcranical attenuation in case of SPAHA was 5 to 10 dB across the measured frequency range. Conclusion: From observed dynamic range and THD, the speech quality delivered by the SPAHA should equal or exceed that delivered by the BAHA. To attain equivalent hearing sensation at lower frequencies, the drive voltage for SPAHA would have to be significantly higher than that for BAHA. For typical speech inputs the power consumption requirements of the SPAHA should be roughly equal to those of the BAHA. Given its performance at high frequencies, the SPAHA seems well-suited to treating SSD. Copyright (C) 2016 by Otology & Neurotology, Inc.

Sudden Pediatric Hearing Loss: Comparing the Results of Combined Treatment (Intratympanic Dexamethasone and Systemic Steroids) With Systemic Steroid Treatment Alone.

Objective: The aim of the present study was to compare hearing improvements obtained with combined intratympanic and systemic steroid therapy, and systemic steroid therapy alone in pediatric patients with idiopathic sudden sensorineural hearing loss (SSHL). Study Design: Retrospective. Setting: Tertiary referral hospital. Patients: Pediatric patients with SSHL. Interventions: The patients were divided into two groups, based on the method of steroid administration: Group 1 (systemic therapy group, n = 23) was treated with oral methylprednisolone alone whereas Group 2 (combination therapy group, n = 26) was treated with combination of oral methylprednisolone and intratympanic dexamethasone injections. Main Outcome Measures: Pre- and post-treatment audiograms were compared with pure-tone averages (PTAs) in each group. Two treatment groups were also compared. The final hearing assessment was performed 4 weeks after completion of the treatment. Results: The mean PTAs before and after the treatment were 61.86 +/- 23.99 and 42.65 +/- 32.69 dB in Group 1 (p = 0.001), and 70.07 +/- 29.74 and 38.85 +/- 32.28 dB in Group 2 (p = 0.001). Pure-tone gain was 20.00 +/- 15.02 dB in Group 1, and 31.69 +/- 28.29 dB in Group 2. Comparison of two groups for post-treatment PTA and pure-tone gains did not yield any statistically significant differences (p = 0.388 and p = 0.132, respectively). Conclusion: Significant hearing improvement may be obtained with use of systemic steroids alone, or simultaneous administration of systemic and intratympanic steroids in pediatric patients with SSHL. Although we did not have a control group, two treatment options appear to offer similar hearing improvements in the pediatric age group higher than the rates obtained with placebo when previous studies in the literature are taken into account.
