In the audiologic research of the Boston VA Normative Aging Study, an auditory age measure has been developed to represent the extent to which an individual is older or younger than his age peers in terms of his hearing ability. Sixteen auditory measures were placed in a stepwise regression procedure: air and bone conduction hearing at various frequencies, speech reception thresholds, speech discrimination scores, and two and three frequency averages. With chronological age as criterion, the resulting equation yielded an auditory age calculated from two variables: air conduction at 8,000 cps and speech reception threshold. Because of redundancy among the larger number of measures, these two effectively index the larger number. The two include high and low frequency measures so are sensitive to high frequency loss at older age.

Implantable bone conduction hearing aids are a valuable alternative to conventional aids for those who cannot use a conventional air conduction aid or find it difficult to use because of an aural discharge, most commonly due to chronic otitis media. Previously reported series of the use of a bone-anchored hearing aid (BAHA) come from the originators of this device, and an independent report of their benefit and use, especially in previous air conduction aid users, would be of value. Twenty-three patients were evaluated at least 6 months after implantation of a BAHA. All 7 previous bone conduction aid users were delighted with their BAHA, reporting increased comfort and hearing benefit that was backed by audiometric evidence. Of the 16 individuals who previously used an air conduction aid, 11 (69%) were delighted users of their BAHA. Unfortunately, the other 5 (31%) reverted to solely using their air conduction aid. There was no obvious predictor as to how these individuals might have been identified prior to implantation. In particular, their pure tone thresholds, especially the bone conduction thresholds, were no different from those of the 11 BAHA users. However, in free field audiometry, the users gained superior benefit from their BAHA compared to their air conduction aid, whereas the nonusers did not. In conclusion, in all series to date, previous users of a conventional bone conduction aid have been delighted users of a BAHA and have gained superior audiometric benefit. This is not necessarily the case with previous air conduction aid users. As most patients rate hearing ability to be more important than absence of an aural discharge, it is important to develop methods that might predict benefit from a BAHA prior to implantation.

AbstractAims:To evaluate the hearing results of a large series of primary stapedotomies, according to American Academy of Otolaryngology, Head and Neck Surgery guidelines and Amsterdam hearing evaluation plots.Study design:Retrospective chart review.Methods:The charts for 1369 consecutive stapedotomy cases were reviewed; 1145 cases of primary stapedotomy were included. Raw data from the audiometric database were evaluated using Amsterdam hearing evaluation plots. The effect on outcomes of using different audiological parameters was analysed.Results:A significant improvement was demonstrated in mean post-operative air conduction and speech reception thresholds, with no change in bone conduction. Air–bone gap closure of 10 dB or more was achieved in 82 per cent of cases. A ‘dead ear’ occurred in one patient (0.1 per cent).Conclusion:This study reports the largest series of primary stapedotomies evaluated with Amsterdam hearing evaluation plots. This method enables visual identification of successful and unfavourable results, providing more accurate and detailed presentation of surgical outcomes.

Hitherto, for persons with impaired hearing who cannot use an air conduction hearing aid, the only alternative has been a conventional spring-loaded bone conduction hearing aid. Now, with minor surgery, a titanium screw can be implanted in the bone behind the ear and a coupling, which penetrates the skin, can be attached, giving a new kind of hearing aid—the “bone-anchored hearing aid.” Improved quality of sound is one of the patients’ subjective assessments. Improvement was not confirmed by a standard speech-discrimination test. With new speech material consisting of sentences in noise, the speech-to-noise ratio (SN) has been determined for 24 patients. Patients who previously used a conventional bone conduction hearing aid improved their SN on the average by 3.3 dB. The most important difference between the two aids related to improved SN is probably the increased audibility between 600 and 6000 Hz.

Objective. To measure the audiological benefit of the Baha SoundArc, a recently introduced nonimplantable wearing option for bone conduction sound processor, and to compare it with the known softband wearing option in subjects with normal cochlear function and a purely conductive bilateral hearing loss.Methods. Both ears of 15 normal hearing subjects were occluded for the time of the measurement, yielding an average unaided threshold of 49 dB HL (0.5 – 4 kHz). Soundfield thresholds, speech understanding in quiet and in noise, and sound localization were measured in unaided conditions and with 1 or 2 Baha 5 sound processors mounted on either a softband or a SoundArc device.Results. Soundfield thresholds and speech reception thresholds were improved by 19.5 to 24.8 dB (p<.001), when compared to the unaided condition. Speech reception thresholds in noise were improved by 3.7 to 4.7 dB (p<.001). Using 2 sound processors rather than one improved speech understanding in noise for speech from the direction of the2nddevice and sound localization error by 23° to 28°. No statistically significant difference was found between the SoundArc and the softband wearing options in any of the tests.Conclusions. Bone conduction sound processor mounted on a SoundArc or on a softband resulted in considerable improvements in hearing and speech understanding in subjects with a simulated, purely conductive, and bilateral hearing loss. No significant difference between the 2 wearing options was found. Using 2 sound processors improves sound localization and speech understanding in noise in certain spatial settings.

Articulation functions were generated on a normal-hearing population with the Auditec of St. Louis cassette recordings of the NU-6 and CID W-22 speech discrimination tests. Both tests were similar and yielded slopes of about 4.4%/dB. Each gave a speech discrimination score of approximately 95% at 32 dB SL. Speech reception thresholds were obtained with monitored live voice and yielded good testretest consistency. Speech thresholds were about 9 dB better than the ANSI (1969) specifications.

Bone conduction involves sound transmission through bone oscillations of the skull or neighboring body areas, resulting in auditory perception. Its significance is not confined to differential diagnosis of hearing loss only. It represents a secondary auditory pathway supplementing air conduction process co instantaneously. Known bio-mechanical mechanisms involved in bone conduction in humans are analyzed and summarized in a most concise way including most recent updates that improve current clinical routine practice. Nevertheless, longstanding assumptions still need further research in order to establish a thorough bone and tissue conduction understanding.

Abstract Background: Stapedectomy and stapedotomy are the standard techniques for stapes fixation surgery. Both techniques depend on the size of window opening (total, partial stapedectomy and small-hole stapedotomy) and the type of prosthesis used. Outcome of technique and prosthesis are controversy. Objective: Evaluate the outcomes of the two surgical techniques (stapedectomy/stapedotomy) and two sizes of prosthesis (Cawthorn 0.6mm/0.3mm) in terms of effectiveness and safety. Material and methods: Sixty-four medical records of patients undergoing stapedectomy or stapedotomy between the year 1995 and 2005 were reviewed. The subjects were classified into three groups including 0.6-mm stapedectomy, 0.6-mm and 0.3-mm stapedotomy group. The pre and post operative air-conduction threshold (AC) and air-bone gap (A-B gap) were compared for each group. The pre-and post-operative differences in pure tone average of AC, pure tone average of bone conduction threshold (BC), AB gap, AC at 4KHz, BC at 4KHz, AC at 8KHz, and speech discrimination score (SDS) were analyzed. The surgical complications were also compared. Results: Means of post-operative AC, and A-B gap were significantly better in all three groups. The mean of postoperative AC at 4KHz was significantly improved only in stapedotomy groups (0.6-mm and 0.3-mm stapedotomy). To compare the hearing outcomes among the three groups, there were no statistically significant differences between 0.6-mm stapedectomy vs. 0.6-mm stapedotomy, and between 0.6- mm vs. 0.3-mm stapedotomy. The complications were found in all three groups. The 0.3-mm stapedotomy had the lowest rate. Conclusion: Stapedectomy versus stapedotomy yields comparable hearing outcomes but stapedotomy results had a better success rate than the stapedectomy. For 0.6-mm stapedotomy vs. 0.3-mm stapedotomy, the overall results in both groups are not significantly different, in terms of both the hearing outcomes and the success rate. In terms of complication rate, 0.6-mm stapedectomy had the highest rate, while 0.3-mm stapedotomy had the lowest.

Background: Outcome measures can be used to improve the quality of the rehabilitation by identifying and understanding which variables influence the outcome. This information can be used to improve outcomes for clients. In clinical practice, pure-tone audiometry, speech reception thresholds (SRTs), and speech discrimination scores (SDSs) in quiet or in noise are common assessments made prior to hearing aid (HA) fittings. It is not known whether SRT and SDS in quiet relate to HA outcome measured with the International Outcome Inventory for Hearing Aids (IOI-HA). Purpose: The aim of the present study was to investigate the relationship between pure-tone average (PTA), SRT, and SDS in quiet and IOI-HA in both first-time and experienced HA users. Research Design: SRT and SDS were measured in a sample of HA users who also responded to the IOI-HA. Study Sample: Fifty-eight Danish-speaking adult HA users. Data Collection and Analysis: The psychometric properties were evaluated and compared to previous studies using the IOI-HA. The associations and differences between the outcome scores and a number of descriptive variables (age, gender, fitted monaurally/binaurally with HA, first-time/experienced HA users, years of HA use, time since last HA fitting, best ear PTA, best ear SRT, or best ear SDS) were examined. A multiple forward stepwise regression analysis was conducted using scores on the separate IOI-HA items, the global score, and scores on the introspection and interaction subscales as dependent variables to examine whether the descriptive variables could predict these outcome measures. Results: Scores on single IOI-HA items, the global score, and scores on the introspection (items 1, 2, 4, and 7) and interaction (items 3, 5, and 6) subscales closely resemble those previously reported. Multiple regression analysis showed that the best ear SDS predicts about 18–19% of the outcome on items 3 and 5 separately, and about 16% on the interaction subscale (sum of items 3, 5, and 6) Conclusions: The best ears SDS explains some of the variance displayed in the IOI-HA global score and the interaction subscale. The relation between SDS and IOI-HA suggests that a poor unaided SDS might in itself be a limiting factor for the HA rehabilitation efficacy and hence the IOI-HA outcome. The clinician could use this information to align the user’s HA expectations to what is within possible reach.

Abstract: Introduction: Baha® Attract is a new transcutaneous bone-conduction hearing aid, which is more preferable in childhood than the conventional percutaneous systems. Aim: Our aim was to demonstrate the possibilities of application in childhood. Method: Eight children have undergone surgeries (mean age of 13.2 ± 3.2 years; “posterosuperior” incision technique, 5 mm implants). The thickness of the skull bone was determined in 72 children (1-8 years old) at the recommended implant site, based on CT scans. Results: The average duration of surgeries was 30 minutes. There were no intra- and postoperative complications observed. Sound processors were fitted at the postoperative 4th week. Hearing measurements proved 51.58±11.22SD dBHL gain in warble tone thresholds, and 43.3 ± 16.02 SD dB in speech discrimination thresholds. The skull bone thickness was measured as 3.39 ± 1.05 SD mm. Conclusion: The Baha Attract system is a new tool for hearing rehabilitation in pediatric population. Preoperative CT provides valuable knowledge about skull bone thickness. Orv.

OBJECTIVE: The purpose of this study was to determine whether revision stapedectomy could precipitate sensorineural hearing loss in the contralateral ear. METHODS: We conducted a retrospective review of 148 patients undergoing primary or revision stapedectomy at an academic, tertiary care facility. RESULTS: Stapedectomy resulted in significant improvements in mean air conduction thresholds in the ipsilateral ear. Overall, there were no significant changes in either the air or bone conduction values of the contralateral ear. Two patients demonstrated a >20-dB decline in speech reception threshold and/or >20% decrease word recognition in the contralateral ear. Both of these patients demonstrated the decline only after revision surgery. CONCLUSION: Revision stapedectomy is on rare occasions associated with hearing loss in the contralateral ear. Contralateral hearing loss after revision stapedectomy may be due to sympathetic cochleolabyrinthitis.
