Wave I latencies were used to predict the magnitude of conductive components in 80 infants and young children (122 ears) with normal hearing, conductive hearing loss due to otitis media or aural atresia, sensorineural hearing loss, and mixed hearing loss. Two prediction methods were used. The first method based predictions on a 0.03-ms wave I latency delay for each decibel of conductive hearing loss. The second method was based on a regression analysis of wave I latency delays and the magnitude of conductive component for the subjects in this study with normal cochlear status. On average, these prediction methods resulted in prediction errors of 15 dB or greater in over one-third of the ears with hearing loss. Therefore, the clinical use of wave I latencies to predict the presence or magnitude of conductive impairment is not recommended for infants and young children. Instead, bone-conduction ABR testing is recommended as a direct measure of cochlear status when behavioral evaluation is not possible.

Introduction The tone-evoked auditory brainstem responses (tone-ABR) enable the differential diagnosis in the evaluation of children until 12 months of age, including those with external and/or middle ear malformations. The use of auditory stimuli with frequency specificity by air and bone conduction allows characterization of hearing profile. Objective The objective of our study was to compare the results obtained in tone-ABR by air and bone conduction in children until 12 months, with agenesis of the external auditory canal. Method The study was cross-sectional, observational, individual, and contemporary. We conducted the research with tone-ABR by air and bone conduction in the frequencies of 500 Hz and 2000 Hz in 32 children, 23 boys, from one to 12 months old, with agenesis of the external auditory canal. Results The tone-ABR thresholds were significantly elevated for air conduction in the frequencies of 500 Hz and 2000 Hz, while the thresholds of bone conduction had normal values in both ears. We found no statistically significant difference between genders and ears for most of the comparisons. Conclusion The thresholds obtained by bone conduction did not alter the thresholds in children with conductive hearing loss. However, the conductive hearing loss alter all thresholds by air conduction. The tone-ABR by bone conduction is an important tool for assessing cochlear integrity in children with agenesis of the external auditory canal under 12 months.

Background: The multiple auditory steady-state response (multiple ASSR) is a promising technique for determining thresholds for infants and children. However, there are few data for infants and young children with hearing loss where multiple-ASSR thresholds have been compared to frequency-specific gold standard (i.e., behavioral or tone-evoked auditory brainstem response [tone ABR]) measures. Purpose: The study compared multiple-ASSR and tone-ABR thresholds and assessed how well “normal” ASSR levels differentiate normal from elevated thresholds. Research Design: Multiple-ASSR and tone-ABR results (to air-conduction stimuli) were obtained in infants and young children with hearing loss or normal hearing. Study Sample: 98 infants with hearing loss (53 infants provided thresholds) and 34 infants with normal hearing. Data Collection and Analysis: Multiple-ASSR and tone-ABR results were typically completed on the same day. Correlations between ASSR and ABR thresholds, linear regressions, and ASSR-minus-ABR threshold difference scores were calculated for each group (normal or hearing loss), and for both groups combined. Results: Multiple-ASSR thresholds (dB HL) were strongly correlated (r = .97) with tone-ABR thresholds (dB nHL) for 500, 1000, 2000, and 4000 Hz. Mean (±1 SD) difference scores (ASSR-minus-ABR) were 10.7 ± 9.0, 9.5 ± 9.4, 9.2 ± 9.0, and 6.3 ± 9.5 dB for 500, 1000, 2000, and 4000 Hz, respectively. The previously published “normal” ASSR levels accurately differentiated normal from elevated thresholds. Out of 523 tests with elevated tone-ABR thresholds, the multiple ASSR was “normal” in only 22 tests. In these 13 infants, other ASSR frequencies were elevated, and thus the infants would not have “passed” the ASSR. Conclusions: There are few studies of infants and young children comparing ASSR thresholds to frequency-specific gold standard measures, especially using the multiple-ASSR technique. The present study, comparing multiple-ASSR to tone-ABR thresholds, nearly doubles the multiple-ASSR sample size in the literature. The results indicate that the multiple-ASSR and tone-ABR thresholds are strongly correlated, and the “normal” multiple-ASSR levels of 50, 45, 40, and 40 dB HL correctly classified children as having “normal” or “elevated” thresholds. However, due to the lack of air- and bone-conduction data in infants with different types and degrees of hearing loss, further ASSR research is needed.

<b><i>Background:</i></b> The ADHEAR™ system (MED-EL, Innsbruck, Austria) is a nonsurgical bone conduction device (BCD) to treat conductive hearing loss (CHL) and single-sided deafness. In contrast to the nonsurgical alternatives on headbands or spectacle frames, the audio processor of ADHEAR is placed retroauricularly on an adhesive adapter. The published evidence on the performance of this system is limited to studies with a trial period of 2–8 weeks. <b><i>Objective:</i></b> This study assesses audiological and subjective outcomes over a period of 12 months, on patients with congenital aural atresia (CAA) using the ADHEAR hearing system. <b><i>Method:</i></b> Fifteen children (mean age: 9.4 ± 4 years; range: 5–16 years) diagnosed with CAA (7 uni/8 bilateral) were included in this prospective, observational, repeated-measures study. Each subject used ADHEAR for 1 year, and the performance was evaluated after 1, 6, and 12 months. Free-field audiometry and speech discrimination tests were performed, and hearing-, general health- and device-specific questionnaires were used. <b><i>Results:</i></b> The unaided sound field threshold improved from an average PTA4 of 63.6 ± 3.4 dB HL to an aided average PTA4 of 29.3 ± 3.0 dB HL after 1 month of device use. The word recognition score (WRS) improved from an average of 27.9 ± 15.9% unaided to an aided average WRS of 91.3 ± 4.4% (<i>p</i> = 0.0003) after 1 month, 92.0 ± 4.1% (<i>p</i> = 0.0002) after 6 months, and 92.7 ± 5.3% (<i>p</i> &#x3c; 0.0001) after 12 months using the ADHEAR system compared to the unaided condition for all 3 time points. The improvements in the speech in noise at 1, 6, and 12 months were as well consistent over time. The average improvement at the signal to noise ratio (SNR) of +5 dB was 58% and 53% at the SNR of +0 dB. No complications were reported, and all patients continued to use the ADHEAR after the study end. The questionnaire results revealed high user satisfaction and an average wearing time of 12 h per day. <b><i>Conclusion:</i></b> This 12-month trial of the nonsurgical adhesive BCD in CAA patients showed sufficient and reliable audiological and subjective outcomes, long wearing time, and high acceptance. The ADHEAR can be considered a suitable option to treat children with CAA for the given indication, without the drawbacks of nonsurgical devices that use pressure for retention of the audio processor or the costs and possible complications involved with a surgical alternative.

The conductive SISI (short increment sensitivity index) test is an indirect procedure to estimate bone-conduction thresholds for middle ear pathology patients. A series of SISI tests are run, beginning at 20 dB S.L. and increasing in 10 dB S.L. steps, until a 100% SISI score is obtained. The following equation predicts the bone-conduction threshold: [Formula: see text] The results of 25 conductive SISI tests on a conductive hearing loss group indicate that the equation approximates the measured B.C. threshold. There was no statistical difference between the predicated B.C. thresholds (12.4 dB) and measured B.C. thresholds (10.4 dB) for the group.

Conductive Hearing

Otosclerosis is the most frequent cause of conductive hearing loss in patients with intact tympanic membrane. It can be treated by surgery with various techniques. Because of limited manipulation and comparably similar results, stapedotomy at present is preferred over other surgical techniques by most surgeons. Here we present the operative results of 35 otosclerotic patients who underwent stapedotomy between January 2009 - October 2010 in the department of Otolaryngology- Head & Neck Surgery of Bangabandhu Sheikh Mujib Medical University, Dhaka Medical College Hospital and Shahid Suhrawardhy medical college & hospital, Dhaka. The aim of this study was to evaluate the hearing results following stapedotomy in otosclerosis surgery. The average air-bone gap of patients improved significantly to 21.74 dB after operation. Other hearing parameters of patients (including air conduction, bone conduction, speech discrimination score, and tinnitus) also improved. No patient experienced persistent vertigo after the operation and pre operative tinnitus resolved in 12 out of 22 patients. Stapedotomy is a safe and effective modality for improving conductive hearing loss in otosclerotic patients. Bangladesh J Otorhinolaryngol; October 2019; 25(2): 85-93
