Abstract
The intricate distribution of the facial nerve within the temporal bone is crucial in otological surgery. Anomalous facial nerve pathways are occasionally observed in middle ear malformations, although intra-tympanic bifurcation of the facial nerve is rare. When managing ossicular malformations with atypical facial nerve trajectories, hearing reconstruction should be prioritized based on the trajectory pattern and presence of the oval window. In this case, stapes surgery was performed due to facial nerve bifurcation within the tympanic cavity. In this case report, a 15-year-old female underwent stapes surgery due to gradually worsening conductive hearing loss. She was monitored at another hospital because of left-sided hearing loss at birth screening using automated auditory brainstem response. Her left ear initially had mild hearing loss, while her right ear remained within normal limits. However, her hearing deteriorated progressively, leading to significant daily challenges by age seven, prompting referral to our hospital. Intraoperatively, findings included defects in the incus-long process and stapes head, along with facial nerve bifurcation around the oval window, and the stapes footplate had poor flexibility. Stapedotomy was performed cautiously to preserve the facial nerve, utilizing a Teflon piston wire for sound transmission reconstruction. Postoperatively, the patient experienced no complications or facial nerve palsy, with hearing improving to 28.8 dB. Understanding the precise pathophysiology of middle ear anomalies is crucial for selecting appropriate surgical approaches. Even though the anomalies could not be evaluated prior to surgery, surgeons must carefully consider the risk of facial nerve injury and choose the optimal technique and reconstruction method tailored to each case, as predicting outcomes solely from preoperative evaluations can be challenging.

Abstract
PURPOSE The indications of Vibrant Soundbridge (VSB) have been expanded to include patients with conductive and mixed hearing loss due to congenital aural atresia (CAA). However, the current evidence supporting the auditory outcomes of VSB is based mainly on case reports and retrospective chart reviews. Therefore, the present systematic review aims to summarize and critically appraise the current evidence regarding the safety and effectiveness of VSB in children and adult patients with CAA. METHODS A systematic literature search retrieved studies that evaluated the outcomes of unilateral or bilateral implantation of VSB in patients with CAA. The bibliographic search was conducted in PubMed, Scopus, EBSCO, and Cochrane Central Register of Controlled Trials (CENTRAL) databases from January 2000 to December 2022. RESULTS Twenty-seven studies were included in the present systematic review. Overall, the speech perception after VSB was good, with a mean word recognition score (WRS) score ranging from 60 to 96.7%. The mean postoperative speech recognition threshold (SRT) after implantation ranged from 20.8 to 50 dB. The effective gain was reported in 15 studies, ranging from 31.3 to 45.5 dB. In terms of user satisfaction with VSB, the included studies showed significant improvements in the patient-reported outcomes, such as the Speech Spatial and Qualities of Hearing scale and Glasgow Hearing Aid Benefit Profile. The VSB implantation was generally safe with low incidence of postoperative complications. CONCLUSION VSB provides significant benefits to individuals with hearing loss owing to CAA, with very good subjective outcomes and a low risk of complications.

Abstract
Bone conduction devices (BCDs) are widely used in the treatment of conductive hearing loss (CHL), but their applications on unilateral CHL (UCHL) patients remain controversial. To evaluate the effects of BCDs in UCHL, a systematic search was undertaken until May 2023 following the PRISMA guidelines. Among the 391 references, 21 studies met the inclusion criteria and were ultimately selected for review. Data on hearing thresholds, speech recognition, sound localization, and subjective questionnaire outcomes were collected and summarized. Moderate hearing threshold improvements were found in UCHL patients aided with BCDs. Their speech recognition abilities improved significantly. However, sound localization results showed wide individual variations. According to subjective questionnaires, BCDs had an overall positive influence on the daily life of UCHL patients, although several unfavorable experiences were reported by some of them. We concluded that the positive audiological benefits and subjective questionnaire results have made BCDs a credible intervention for UCHL patients. Before final implantations, UCHL patients should first go through a period of time when they were fitted with non-implantable BCDs as a trial.

Abstract
Despite normal hearing in one ear, individuals with congenital unilateral aural atresia may perceive difficulties in everyday listening conditions typically containing multiple sound sources. While previous work shows that intervention with bone conduction devices may aid spatial hearing for some children, testing conditions are often arranged to maximize any benefit and are not very similar to daily life. The benefit from amplification on spatial tasks has been found to vary between individuals, for reasons not entirely clear. This study has sought to expand on the limited knowledge on how children with unilateral aural atresia recognize speech masked by competing speech, and how horizontal sound localization accuracy is affected by the degree of unilateral hearing loss and by amplification using unilateral bone conduction devices when fitted before 3 years of age. In a within-subject, repeated measures design, including 11 children (mean age = 7.9 years), bone conduction hearing device (BCD) amplification did not negatively affect horizontal sound localization accuracy. The effect on speech recognition scores showed greater inter-individual variability. No benefit from amplification on a group level was found. There was no association between age at fitting and the benefit of the BCD. For children with poor unaided sound localization accuracy, there was a greater BCD benefit. Unaided localization accuracy increased as a function of decreasing hearing thresholds in the atretic ear. While it is possible that low sound levels in the atretic ear provided access to interaural localization cues for the children with the lowest hearing thresholds, the association has to be further investigated in a larger sample of children.

Abstract
OBJECTIVE Compare outcomes of surgical techniques in percutaneous bone-anchored hearing implant surgery. STUDY DESIGN Matched retrospective cohort study. SETTING Tertiary referral center. PATIENTS Electronic review of adult and pediatric patients who underwent bone conduction device surgery by either the Minimally-invasive Ponto Surgery (MIPS) technique or the linear incision with no soft tissue removal (LnSTR) technique or between August 2015 and April 2018 at our facility. INTERVENTION Patients in MIPS group underwent Minimally invasive Ponto Surgery (MIPS) technique, while those in LnSTR group underwent LnSTR technique. MAIN OUTCOME MEASURE Major outcome was presence/severity of localized skin reaction. Secondary outcomes included cosmetic outcome, revision surgery, minor adverse events, device utilization, and postoperative aided speech recognition thresholds (SRTs) across 250 to 4000 Hertz (Hz). RESULTS Fifty patients met inclusion criteria. There was a significantly lower rate of localized cutaneous reactions for the MIPS group (4.5%) compared with LnSTR group (33.3%; p = 0.026). Rate of revision surgery was significantly less for MIPS (13.6%) compared with LnSTR (20.8%; p = 0.008). Occurrence of poor cosmetic outcome was noted significantly less for the MIPS group (9.1%) compared with LnSTR patients (20.8%; p = 0.005). Minor adverse events and aided SRTs were comparable between groups. CONCLUSIONS MIPS leads to a statistically significant decrease in localized cutaneous reaction compared with LnSTR. Both the LnSTR and MIPS techniques are safe and effective in the treatment of hearing loss, however MIPS may be superior in certain cases by offering improved healing, decreasing needs for wound care, and possibly decreasing need for frequent follow up.

Abstract
Severe conductive hearing loss due to unilateral aural atresia leads to auditory and developmental disorders, such as difficulty in hearing in challenging situations. Bone conduction devices compensate for the disability but unfortunately have several disadvantages. The aim of this study was to evaluate the benefits of cartilage conduction (CC) hearing aids for speech perception in unilateral aural atresia. Eleven patients with unilateral aural atresia were included. Each participant used a CC hearing aid in the atretic ear. Speech recognition scores in the binaural hearing condition were obtained at low speech levels to evaluate the contribution of aided atretic ears to speech perception. Speech recognition scores were also obtained with and without presentation of noise. These assessments were compared between the unaided and aided atretic ear conditions. Speech recognition scores at low speech levels were significantly improved under the aided atretic ear condition (p < 0.05). A CC hearing aid in the unilateral atretic ear did not significantly improve the speech recognition score in a symmetrical noise presentation condition. The binaural hearing benefits of CC hearing aids in unilateral aural atresia were predominantly considered a diotic summation. Other benefits of binaural hearing remain to be investigated.

Abstract
OBJECTIVE To characterize the adherence of bone conduction hearing devices (BCHDs) for hearing management in children with unilateral congenital aural atresia (UCAA) in relation to the age of offer and fitting. BCHD Soft Bands help predict amplification benefits before surgery can be performed beginning around five years when both hearing and parental compliance reach stability. We hypothesized device compliance might decrease with age of fitting from lack of early acclimatization. METHODS Retrospective case series of patients less than five years old at a tertiary pediatric center's microtia clinic database, born between 2014 and 2018 with UCAA. Adherence was assessed through electronic health record note documentation at less than 1 year, 1-2 years, and greater than 2 years from fitting. The ages at offer and fitting, along with the time from offer to fitting, were recorded. RESULTS One hundred and eight patients with UCAA were identified, including 46 patients fit with a BCHD used for further analysis. Adherence rates at 1 year, 1-2 years, and greater than 2 years were 47.8%, 30%, and 43.5%, respectively. However, there was no significant association between age offered, age fit, or time from offer to fit and adherence at all time points. Also, there was no significant difference between ages at the time of BCHD offer for those who chose not to proceed with fitting (20.9 months) compared to the age of offer in patients that were subsequently fit (13.9 months). CONCLUSION BCHD adherence in patients less than five years old may not be affected by the age offered or fit. The time between offer and fitting was also not associated with usage. BCHDs should be offered to UCAA patients regardless of age. Further investigation in this younger age group would help expand these findings.

Abstract
OBJECTIVE To characterize the use of bone conduction hearing devices (BCHD) for hearing management in children with unilateral congenital aural atresia (CAA) at a tertiary pediatric center's microtia clinic while assessing challenges in acquisition. BCHD generally provides better audiologic outcomes than atresiaplasty in pediatric CAA. BCHD is formally recommended for only bilateral CAA, although literature has begun to show benefit in unilateral CAA. METHODS A retrospective case series of patients born between 2014 and 2018 with unilateral microtia at an urban tertiary care children's hospital collected information on demographics, CAA laterality, hearing loss (HL) severity, management, and acquisition. Statistical analysis aided characterization of BCHD use. RESULTS 131 patients (65% males) were included with a mean age of 3.5 years. 108 (82%) patients with unilateral microtia were used for further analysis, and right sided microtia was most common (67.6%). Of patients with auditory brain response (ABR) testing available, 70% demonstrated conductive HL, 16% mixed HL, 1% sensorineural HL, 6% no HL secondary to grade 1 microtia, and 7% were pending evaluation. Overall, 46 (42.6%) patients with unilateral microtia obtained a BCHD. 68.7% of those offered a BCHD after ABR opted for acquisition. The average length of time from offer to fit was about 6 months. CONCLUSION Even with thorough consultation and follow up, less than half of the patients with unilateral CAA received a BCHD. Missed initial ABR appointments that lead to BCHD recommendation seem to be the greatest limiting factor, while demographics did not play a confounding role. Family education and future research on obstacles preventing BCHD use in unilateral CAA will help standardize management and improve hearing within this critical auditory period.

Abstract
OBJECTIVES To review the trialing and uptake of hearing aids in children with unilateral microtia or canal atresia, known collectively as congenital unilateral conductive hearing loss (CUCHL), observed in a tertiary hospital and local peripheral services. MATERIALS AND METHODS A retrospective review of medical records for patients with CUCHL was conducted using data from a shared audiology database at a tertiary children's hospital. RESULTS We identified 45 patients with CUCHL and excluded seven of them due to missing data. Of the 38 patients, 16 (16/38, 42%) did not have any subjective hearing complaints. Furthermore, 32% (12/38) of patients attended audiology at a tertiary centre and 83% (10/12) from this group trialled a hearing aid. In comparison, 46% (12/46) whose audiology care was delivered peripherally trialled aiding. Of the patients from the tertiary center, 58% (7/12) are still using a hearing aid compared to 27% (7/26) of patients from peripheral centers. CONCLUSION Our analysis shows that patients with CUCHL are more likely to try hearing aids and continue using them if their audiology care is in a tertiary center. Allowing for a small sample size, this may indicate a health inequality. Agreeing on minimum standards for the management of patients with CUCHL or managing them in a designated center could increase consistency.

Abstract
OBJECTIVES The main objective of this study was to evaluate the audiological benefit of the ADHEAR system in a group of children with a uni- or bilateral conductive hearing loss (CHL) during a short-term exposure of three weeks, and to compare it to a conventional bone conduction hearing aid (BCHA) on a softband. The secondary aim was to assess the quality of life improvement and patient satisfaction with the ADHEAR system. METHODS AND MATERIALS The study was designed as a prospective study with repeated measures, where each subject served as his/her own control. Ten children (4-17 y/o) with a uni- or bilateral congenital or acquired CHL were included in this study. Pure tone audiometry and speech audiometry in quiet, both unaided and aided, were performed initially with the ADHEAR system and a BCHA on a softband, and after three weeks with the ADHEAR alone. Furthermore, patient satisfaction and quality of life were assessed using the SSQ12 and the ADHEAR questionnaire. RESULTS The mean unaided free field hearing threshold of 50 dB HL (with 95%CI between 41.7 and 57.5 dB HL) expressed in 'Bureau International d'Audiophonologie' (BIAP), improved significantly by 22 dB (13.0-29.9) with the ADHEAR and by 23 dB (13.6-32.9) with the BCHA (p < 0.001). Furthermore, the mean unaided speech recognition threshold (SRT) in quiet improved significantly by 19 dB (10.3-28.1) with the ADHEAR and by 21 dB (12.6-29.4) with the BCHA (p < 0.001). For both audiological tests, there were no significant differences between the ADHEAR and the BCHA. After three weeks of use, the mean pure tone threshold of 28 dB HL (20.0-36.5) and the mean SRT of 47 dB SPL (41.9-51.5) with the ADHEAR system were comparable and not significantly different than the outcomes during the first visit. Speech understanding in noise and in multiple streams, sound localization and sound quality were rated significantly better with the ADHEAR, compared to the ratings without the ADHEAR system (p < 0.001). None of the children reported skin irritations or pain. CONCLUSIONS The children included in our study had significantly improved hearing thresholds, speech perception in quiet and quality of life with the ADHEAR. The device can be an effective treatment method and a valuable alternative to other BCHA for children with a CHL, although the subjective experience of each child has to be taken into account.

Abstract
Bone conduction implants transfer sound to the inner ear through direct vibration of the skull. In patients with skull base tumors and infections, these devices can bypass a dysfunctional ear canal and/or middle ear. Though not all skull base surgery patients opt for bone conduction hearing rehabilitation, a variety of these devices have been developed and marketed over time. This article reviews the evolution and existing state of bone conduction technology.

Abstract
Introduction
Bone anchored hearing aids (BAHA) represent a useful surgical option for patients with single sided deafness.
Objectives
To compare multiple techniques for BAHA implantation regarding postoperative complications, operative time, and duration between the surgery and the first use of the BAHA.
Methods
A retrospective study was conducted of all patients receiving implantation of a BAHA from August of 2008 to October of 2014. Data collected included: patient age, gender, side operated, abutment length, operative time, duration until first use of the BAHA, operative technique, and postoperative complications. The statistical analysis was performed using analysis of variance (ANOVA), Tukey pairwise comparison, chi-square, and paired
t
-test. Statistical significance was determined using a level of
p
< 0.05.
Results
A total of 88 patients (43 female and 45 male) were included in the data analysis. A total of 80 complications were documented, and these complications were classified according to the Holgers criteria. A significant difference in the total postoperative complications existed between the six techniques used (ANOVA;
p
< 0.01). In addition, there was also a significant difference among the six techniques employed regarding the operative time (ANOVA;
p
< 0.01). The average time duration until fitting of the BAHA processor among the various techniques trended toward but did not reach statistical significance (ANOVA;
p
= 0.16).
Conclusions
Significant differences in the operative outcomes exist among the various techniques for BAHA implantation. Based on the statistical analysis of our data, the BAHA Attract system (Cochlear Ltd., Sidney, Australia) requires greater operative time, but it is associated with less postoperative complications than percutaneous techniques and its processor may be fitted significantly sooner.

Hearing improvement with softband and implanted bone-anchored hearing devices and modified implantation surgery in patients with bilateral microtia-atresia. Int J Pediatr Otorhinolaryngol 2018; 104:120-125. [PMID: 29287851 DOI: 10.1016/j.ijporl.2017.11.010] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2017] [Revised: 10/30/2017] [Accepted: 11/01/2017] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To evaluate auditory development and hearing improvement in patients with bilateral microtia-atresia using softband and implanted bone-anchored hearing devices and to modify the implantation surgery. METHODS The subjects were divided into two groups: the softband group (40 infants, 3 months to 2 years old, Ponto softband) and the implanted group (6 patients, 6-28 years old, Ponto). The Infant-Toddler Meaning Auditory Integration Scale was used conducted to evaluate auditory development at baseline and after 3, 6, 12, and 24 months, and visual reinforcement audiometry was used to assess the auditory threshold in the softband group. In the implanted group, bone-anchored hearing devices were implanted combined with the auricular reconstruction surgery, and high-resolution CT was used to assess the deformity preoperatively. Auditory threshold and speech discrimination scores of the patients with implants were measured under the unaided, softband, and implanted conditions. RESULTS Total Infant-Toddler Meaning Auditory Integration Scale scores in the softband group improved significantly and approached normal levels. The average visual reinforcement audiometry values under the unaided and softband conditions were 76.75 ± 6.05 dB HL and 32.25 ± 6.20 dB HL (P < 0.01), respectively. In the implanted group, the auditory thresholds under the unaided, softband, and implanted conditions were 59.17 ± 3.76 dB HL, 32.5 ± 2.74 dB HL, and 17.5 ± 5.24 dB HL (P < 0.01), respectively. The respective speech discrimination scores were 23.33 ± 14.72%, 77.17 ± 6.46%, and 96.50 ± 2.66% (P < 0.01). CONCLUSIONS Using softband bone-anchored hearing devices is effective for auditory development and hearing improvement in infants with bilateral microtia-atresia. Wearing softband bone-anchored hearing devices before auricle reconstruction and combining bone-anchored hearing device implantation with auricular reconstruction surgery may bethe optimal clinical choice for these patients, and results in more significant hearing improvement and minimal surgical and anesthetic injury.

Abstract
OBJECTIVE To investigate the emergence of binaural summation in patients with unilateral congenital aural atresia undergoing surgical correction. STUDY DESIGN Preoperative and postoperative audiometric testing in a prospective cohort of 10 patients with unilateral congenital aural atresia. SETTING University-based tertiary care center. PATIENTS Ten patients (ages 6-53) with an average 69 dB (±9 dB sd) unilateral conductive hearing loss, normal hearing in the nonatretic ear, and normal bone conduction in the atretic ear. INTERVENTIONS Pre- and postoperative hearing in noise test in quiet and in noise. MAIN OUTCOME MEASURES Levels of sentences presented from a single central speaker were adaptively varied to determine a speech reception threshold (SRT), first in quiet and then with simultaneous multitalker babble at 65 dB SPL from the same speaker. RESULTS Preoperative SRT was worse than normal controls in both quiet (p = 0.001) and in noise (p = 0.05), as expected. Postoperative SRT in quiet improved 3.5 dB (marginally significant with one-tailed p value of 0.05); thresholds in noise improved an insignificant 0.8 dB (one-tailed p = 0.2). Converting results to dB-worse-than normal, atresia patients did better in noise (relative to normal) than in quiet (p = 0.008). CONCLUSION The expected summation effect (3 dB) occurs after atresia surgery in quiet but not in noise. Relative to normal, these patients performed better in noise than quiet, perhaps because these patients develop skills attending to threshold-level speech in noise during their years without binaural benefit.

Abstract
OBJECTIVE There is no consensus regarding the benefit of implantable hearing aids in congenital unilateral conductive hearing loss (UCHL). This study aimed to measure sound source localization performance in patients with congenital UCHL and contralateral normal hearing who received a new bone conduction implant. STUDY DESIGN Evaluation of within-subject performance differences for sound source localization in a horizontal plane. SETTING Tertiary referral center. PATIENTS Five patients with atresia of the external auditory canal and contralateral normal hearing implanted with transcutaneous bone conduction implant at the Medical University of Vienna were tested. INTERVENTION Activated/deactivated implant. MAIN OUTCOME MEASURE Sound source localization test; localization performance quantified using the root mean square (RMS) error. RESULTS Sound source localization ability was highly variable among individual subjects, with RMS errors ranging from 21 to 40 degrees. Horizontal plane localization performance in aided conditions showed statistically significant improvement compared with the unaided conditions, with RMS errors ranging from 17 to 27 degrees. The mean RMS error decreased by a factor of 0.71 (p < 0.001). CONCLUSION Analysis revealed improved sound localization performance in a horizontal plane with the activated transcutaneous bone conduction implant. Some patients with congenital UCHL might be capable of developing improved horizontal plane localization abilities with the binaural cues provided by this device.

Abstract
After more than 25 years of clinical experience, the BAHA (bone-anchored hearing aid) system is a well-established treatment for hearing-impaired patients with conductive or mixed hearing loss. Owing to its success, the use of the BAHA system has spread and the indications for application have gradually become broader. New indications, as well as clinical applications, were discussed during scientific roundtable meetings in 2004 by experts in the field, and the outcomes of these discussions are presented in the form of statements. The issues that were discussed concerned BAHA surgery, the fitting range of the BAHA system, the BAHA system compared to conventional devices, bilateral application, the BAHA system in children, the BAHA system in patients with single-sided deafness, and, finally, the BAHA system in patients with unilateral conductive hearing loss.

Abstract
OBJECTIVES (1) To describe the benefits of the minimally invasive punch technique without soft tissue reduction (PT) for the placement of percutaneous osseointegrated auditory implants. (2) To compare and contrast techniques and outcomes from PT with the linear technique with soft tissue reduction (LT). STUDY DESIGN Case series with chart review SETTING Performed at a tertiary otology practice at an academic medical center. SUBJECTS AND METHODS LT was used until 2012 when a switch was made for all patients to PT. Preoperative variables recorded included age, sex, BMI, smoking status, indication, device selected, and abutment length. Outcomes measures included surgical time, skin reaction grading by Holgers score at 1 week and at most recent follow-up, and any other complications. Two-sample t test and χ(2) was used to compare. RESULTS A total of 51 patients (34 LT, 17 PT) were identified. Surgical time was found to be significantly shorter for the PT group (LT, 49.2 min; PT, 13.4 min; P < .001). There were no statistically significant differences between LT and PT for mean Holgers at first (LT, 0.24; PT, 0.47; P = .87) or final follow-up (LT, 0.62; PT, 0.41; P = .22). CONCLUSIONS The punch technique offers several potential surgical and cosmetic advantages over the linear technique without compromising skin-reactivity outcomes. This study supports a growing trend toward minimally invasive percutaneous auditory implant surgery.

Abstract
OBJECTIVE To compare the effectiveness of two types of treatment for unilateral hearing loss (UHL), bone-anchored hearing instruments (BAHI) and a dental device (SoundBite). DESIGN Either BAHI or SoundBite were worn for 30 days, and then the devices were swapped and the second device was worn for 30 days. Measures included unaided and aided sound-field thresholds, sound localization, and perception of speech in babble. The APHAB questionnaire was administered for each trial period. STUDY SAMPLE Nine adult BAHI wearers with UHL. RESULTS Mid-frequency aided thresholds were lower for SoundBite than for BAHI. Both devices gave benefits for localization after 30 days, but there was no difference between devices. Speech perception was better for both devices than for unaided listening when the target speech came from the poorer hearing side or in front, and the interfering babble came from the better-hearing side. There was no consistent difference between devices. APHAB scores were better for SoundBite than for BAHI. CONCLUSIONS Speech perception and sound localization were similar for the two types of device, but the SoundBite led to lower aided thresholds and better APHAB scores than the BAHI.

Abstract
OBJECTIVES To examine sentence recognition and self-report outcomes in hearing-impaired persons with different auditory profiles and who were fitted unilaterally with a bone-anchored hearing aid. STUDY-DESIGN Prospective cohort study. SETTING Tertiary referral unit. PATIENTS Data were collected of six patients with single-sided deafness (SSD), seven with a mild to severe hearing loss at the bone-anchored hearing aid side and (near-)normal hearing at the other side and six with a severe bilateral hearing loss. MAIN OUTCOME MEASUREMENTS Sound field thresholds, and sentence recognition in noise (presented from different angles) with bone-anchored hearing aid, without bone-anchored hearing aid and with bone-anchored hearing aid and other ear occluded. In addition, the Speech, Spatial and Qualities of hearing scale and the Abbreviated Profile of Hearing Aid Benefit questionnaire were administered as self-report measures. RESULTS Patients with single-sided deafness listened mainly with their non-bone-anchored hearing aid ear, although the bone-anchored hearing aid lifted the head shadow effect. Patients with mild to severe hearing loss at the bone-anchored hearing aid side and (near-)normal hearing at the other side performed significantly differently in aided and unaided conditions and even regained limited binaural sensitivity with the device. The latter was also true for the patients with severe bilateral hearing loss. However, their hearing loss at the non-bone-anchored hearing aid side was too great to contribute to hearing and they listened predominantly with their bone-anchored hearing aid. Self-report outcomes provided useful information on hearing disability, although this information was not significantly differently for the 3 groups of patients. CONCLUSIONS The bone-anchored hearing aid enhanced performance in different hearing configurations, albeit to different extents.

Abstract
We examined horizontal directional hearing in patients with acquired severe unilateral conductive hearing loss (UCHL). All patients (n = 12) had been fitted with a bone conduction device (BCD) to restore bilateral hearing. The patients were tested in the unaided (monaural) and aided (binaural) hearing condition. Five listeners without hearing loss were tested as a control group while listening with a monaural plug and earmuff, or with both ears (binaural). We randomly varied stimulus presentation levels to assess whether listeners relied on the acoustic head-shadow effect (HSE) for horizontal (azimuth) localization. Moreover, to prevent sound localization on the basis of monaural spectral shape cues from head and pinna, subjects were exposed to narrow band (1/3 octave) noises. We demonstrate that the BCD significantly improved sound localization in 8/12 of the UCHL patients. Interestingly, under monaural hearing (BCD off), we observed fairly good unaided azimuth localization performance in 4/12 of the patients. Our multiple regression analysis shows that all patients relied on the ambiguous HSE for localization. In contrast, acutely plugged control listeners did not employ the HSE. Our data confirm and further extend results of recent studies on the use of sound localization cues in chronic and acute monaural listening.

Abstract
CONCLUSION The overall results show a high ratio of satisfaction in the sample population, which is in accordance with a successful BAHA counselling and rehabilitation of their hearing impairment. OBJECTIVES The acceptance of a bone anchored hearing aid (BAHA) device by a south European population, which could be expected to have some reticence for wearing this device, has been investigated. METHODS The outcome of BAHA implantation was assessed in 24 patients with bilateral and unilateral hearing loss by administration of several questionnaires, such as the Handicap Hearing Inventory (HHI), Client Oriented Scale of Improvement (COSI), Open and General Glasgow Benefit Inventory and Entific Medical System QoL, along with a complete audiological test battery. RESULTS Speech reception threshold (SRT) in bilateral cases improved both in quiet and in noise. In unilateral cases, word perception and accuracy of sound localization improved when sound was presented from the back. COSI scores, at both the intermediate and the final evaluations, showed a fair adaptation level of the patients and their satisfaction for prefixed targets.

Abstract
Previously, unilateral hearing impairment (UHI) has been considered of little consequence. However, a recent meta-analysis of children with UHI displayed educational and behavioural problems and possible delays of speech and language development. Further, patients with UHI consequently report hearing difficulties. Our study investigated hearing function, possible inner ear protection, and self-assessed hearing problems in 57 subjects aged between 3-80 years with single-sided congenital ear malformations and conductive UHI. Pure-tone thresholds and speech recognition (quiet, noise) were measured, and all patients completed a self-assessment questionnaire. Pure-tone thresholds corresponding to sensorineural function did not significantly differ between the normal (air conduction) and affected ear (bone conduction). However, speech recognition in both quiet and in noise was normal on the non-affected side but significantly worse on the malformed side. A moderate to high degree of self-assessed hearing problems were reported. In conclusion, hearing function in the affected ear was found to be subnormal in terms of supra threshold signal processing. Furthermore, a high degree of hearing difficulty was reported. Therefore, active treatment, surgery, or hearing amplification, might be considered.

Abstract
Objectives: We evaluated the clinical outcome measures of fixture loss and skin reactions in older-adult users of percutaneous bone-anchored hearing aids (BAHAs). Methods: We performed a retrospective analysis of 224 older adults (at least 60 years of age) who underwent implantation of 248 implants with the simplified Nijmegen surgical technique between January 1995 and May 2007. Results: During a mean follow-up of 39 months (range, 0 to 144 months), 16 of the 248 implants were lost (6.5%). The causes were failed osseointegration in 9 cases, trauma in 6 cases, and implant loss in irradiated bone in 1 case. There were no losses due to infection. Implant loss was not significantly correlated with age. In 40 implants (16.9%), severe skin reactions of Holgers grade 2 or more were observed. Skin revision surgery was performed around 6 implants (2.4%). None of the patients had an 8.5-mm abutment to overcome severe skin reactions. Conclusions: The outcome of BAHA surgery in older adults was favorable. The rate of implant loss was comparable with that in the overall population of BAHA recipients. There were low risks of severe skin reactions or developing thick skin around the implant.

Abstract
Objectives: A single vertical skin incision with subcutaneous tissue removal is a cosmetic alternative for Baha implant placement. We aimed to determine the preliminary complication rate using a 4-cm vertical skin incision. Study Design: Retrospective review. Subjects and Methods: Vertical incision Baha implant placements from January 2006 to August 2007 were reviewed. Complications including skin irritation, skin overgrowth, and implant extrusion were tallied. A total of 71 patients underwent surgery, with a mean follow-up time of 7 months. Results: There were five minor complications (three cases of skin irritation, one wound infection requiring oral antibiotics, one postoperative hematoma) and seven major complications (one case of irritation requiring abutment removal, six cases of skin overgrowth or infection requiring flap revision), for a total complication rate of 16.9 percent. Conclusions: A single vertical incision for Baha implant placement has a complication rate similar to that of traditional dermatome use in this preliminary study. Patients with thick scalps or risk factors for hypertrophic scarring may require longer abutments.

Abstract
OBJECTIVE To study the audiologic outcome of bone-anchored hearing aid (BAHA) application in patients with congenital unilateral conductive hearing impairment. STUDY DESIGN Prospective audiometric evaluation on 20 patients. SETTING Tertiary referral center. PATIENTS The experimental group comprised 20 consecutive patients with congenital unilateral conductive hearing impairment, with a mean air-bone gap of 50 dB. METHODS Aided and unaided hearing was assessed using sound localization and speech recognition-in-noise tests. RESULTS Aided hearing thresholds and aided speech perception thresholds were measured to verify the effect of the BAHA system on the hearing acuity. All patients fulfilled the criteria that the aided speech reception thresholds or the mean aided sound field thresholds were 25 dB or better in the aided situation. Most patients were still using the BAHA almost every day. Sound localization scores varied widely in the unaided and aided situations. Many patients showed unexpectedly good unaided performance. However, nonsignificant improvements of 3.0 (500 Hz) and 6.9 degrees (3,000 Hz) were observed in favor of the BAHA. Speech recognition in noise with spatially separated speech and noise sources also improved after BAHA implantation, but not significantly. CONCLUSION Some patients with congenital unilateral conductive hearing impairment had such good directional hearing and speech-in-noise scores in the unaided situation that no overall significant improvement occurred after BAHA fitting in our setup. Of the 18 patients with a complete data set, 6 did not show any significant improvement at all. However, compliance with BAHA use in this patient group was remarkably high. Observations of consistent use of the device are highly suggestive of patient benefit. Further research is recommended to get more insight into these findings.

Abstract
OBJECTIVES Bilateral BAHAs in adults with bilateral hearing loss (BHL) have proven to be superior to unilateral fitting, in both audiologically measurements and in overall patient satisfaction. There have been no similar studies in children. Furthermore, a recent meta-analysis of children with unilateral hearing loss (UHL) has shown numerous negative consequences. The objectives of the study were to investigate whether fitting of bilateral BAHAs in children with conductive BHL give additional hearing benefits, to investigate the effects of unilateral hearing aids in children with conductive UHL, and to identify different aspects of auditory problems in children with conductive UHL or BHL. STUDY DESIGN This was a prospective study involving 22 children with either conductive UHL (unaided or with unilateral hearing aid) or conductive BHL (with unilateral or bilateral BAHAs) and 15 controls. METHODS Baseline audiometry, tone thresholds in a sound field, speech recognition in noise and sound localization were tested without, and with unilateral and bilateral hearing aids. Two questionnaires, MAIS & MUSS and IOI-HA, were completed. RESULTS Two problem areas were identified in the children with hearing impairment: in reactions to sounds and in intelligibility of speech. An additional BAHA in the children with BHL resulted in a tendency to have improved hearing in terms of better sound localization and speech recognition in noise. Fitting of unilateral hearing aids in the children with UHL gave some supplementary benefit in terms of better speech recognition in noise but no positive effect on ability to localize sound could be detected. Even so, all children fitted with hearing aids - either unilaterally or bilaterally - reported a positive outcome with their devices in the self-assessment questionnaire. CONCLUSIONS Children with either UHL or BHL displayed several problems within the hearing domain. Fitting of bilateral BAHAs in children with BHL and of a single-sided hearing aid in children with UHL appears to have some supplementary audiological benefits and also renders high patient satisfaction. In order to investigate the possible supplementary effects of hearing aids, a 3-month trial of BAHA on Softband, either unilaterally or bilaterally, may be of value in children with conductive UHL or BHL, respectively.

Abstract
OBJECTIVE This study completed an evidence-based practice systematic review of the nonacoustic benefits for adult patients receiving bone-anchored hearing aid(s) (BAHAs) relative to other forms of amplification (i.e., none, bone-conduction hearing aids [BCHAs], or air-conduction hearing aids [ACHAs]). DESIGN Systematic review. METHODS ComDisDome and PubMed were used to perform a comprehensive search for studies that were of at least level III of evidence. Three independent reviewers completed the search, quality assessment, and data extraction. RESULTS Out of 28 studies, seven studies were identified, three of which were prospective and four of which were retrospective within-subject comparison designs. Nearly all of the studies were of small sample size and/or limited methodological quality, primarily because of logistics (e.g., heterogeneity of subject samples and prior experience with amplification). CONCLUSIONS The evidence identified in this review is limited regarding the nonacoustic benefits of BAHAs compared with unaided conditions or other types of amplification. Professionals should use caution when counseling patients about the quality of life (QOL) benefits of these devices. Routine use of QOL outcome measures and standardized methods for reporting findings are critical in demonstrating the nonacoustic benefits of BAHAs.

Abstract
OBJECTIVE Vibromechanical stimulation with a semi-implantable bone conductor (Entific BAHA device) overcomes some of the head-shadow effects in unilateral deafness. What specific rehabilitative benefits are observed when the functional ear exhibits normal hearing versus moderate sensorineural hearing loss (SNHL)? DESIGN The authors conducted a prospective trial of subjects with unilateral deafness in a tertiary care center. PATIENTS This study comprised adults with unilateral deafness (pure-tone average [PTA] > 90 dB; Sp.D. < 20%) and either normal monaural hearing (n = 18) or moderate SNHL (PTA = 25-50 dB: Sp.D. > 75%) in the contralateral functional ear (n = 5). INTERVENTIONS Subjects were fit with contralateral routing of signal (CROS) devices for 1 month and tested before (mastoid) implantation, fitting, and testing with a bone-anchored hearing aid (BAHA). OUTCOME MEASURES Outcome measures were: 1) subjective benefit; 2) source localization tests (Source Azimuth Identification in Noise Test [SAINT]); 3) speech discrimination in quiet and in noise assessed with Hearing In Noise Test (HINT) protocols. RESULTS There was consistent satisfaction with BAHA amplification and poor acceptance of CROS amplification. General directional hearing decreased with CROS use and was unchanged by BAHA and directional microphone aids. Relative to baseline and CROS, BAHA produced significantly better speech recognition in noise. Twenty-two of 23 subjects followed up in this study continue to use their BAHA device over an average follow-up period of 30.24 months (range, 51-12 months). CONCLUSION BAHA amplification on the side of a deaf ear yields greater benefit in subjects with monaural hearing than does CROS amplification. Advantages likely related to averting the interference of speech signals delivered to the better ear, as occurs with conventional CROS amplification, while alleviating the negative head-shadow effects of unilateral deafness. The advantages of head-shadow reduction in enhancing speech recognition with noise in the hearing ear outweigh disadvantages inherent in head-shadow reduction that can occur by introducing noise from the deaf side. The level of hearing impairment correlates with incremental benefit provided by the BAHA. Patients with a moderate SNHL in the functioning ear perceived greater increments in benefit, especially in background noise, and demonstrated greater improvements in speech understanding with BAHA amplification.
