“…Regarding the first of these potential issues, we believe that a new wearing option can be of substantial importance for current and future patients, if it is perceived as attractive by the users. It is known that a significant number of patients chooses not to use or to discontinue the use of bone conduction devices because either a surgical intervention is needed or the nonsurgical wearing option is not aesthetically appealing [ 7 , 24 , 25 ]. It is therefore not surprising that at least one other manufacturer has presented a new nonsurgical alternative to implantable bone conduction devices recently [ 26 ].…”

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 the 2nd device 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.

Hearing and vestibular rehabilitation, with a focus on the elderlyThe increasing proportion of our patients in the 'elderly' age group in the developed world has effects on ENT as well as every other branch of medicine. In The Journal of Laryngology & Otology in the recent past, we have looked at a variety of topics of particular interest to the otolaryngologist and geriatrician, including pharyngeal pouch, 1 vestibular dysfunction and presbyacusis, 2,3 and cochlear implantation. 4 In this issue, an auditory brainstem response study focuses on the mechanism of hearing difficulty in the elderly, especially in noisy surroundings, comparing the elderly and young adults. 5 This revealed significantly lower amplitudes and increased latencies in brainstem responses in the elderly, indicating that subcortical mechanisms are involved in this deficiency. With regard to the frequent need for vestibular rehabilitation therapies in the elderly, it is disappointing but perhaps not surprising that elderly males are apparently more likely to fail to complete vestibular rehabilitation programmes than their younger counterparts. 6 Vestibular rehabilitation programmes may not be inexpensive, but bone-anchored hearing aids are an established and necessarily expensive aid to hearing impairment rehabilitation. The review paper from Manchester helps us to understand why the take-up of this technology is not always as high as might be hoped for. 7 The authors call for much more evidence to help providers focus their efforts appropriately and to help patients take advantage of what could help them a great deal.This issue of The Journal has papers on both adult and paediatric subglottic stenosis. Sharma and colleagues describe a decade of experience in balloon dilatation at Great Ormond Street Hospital, which has considerable advantages over open surgery in these challenging cases. 8 These authors provide practical guidance on the technique based on 166 cases. Nicolli and colleagues, from Pennsylvania, describe a retrospective case-control study in adults, in which they identify obesity and diabetes mellitus as risk factors for the development of subglottic stenosis. 9 These papers complement a paper from New Delhi published in 2014, which investigated the aetiology and management of subglottic stenosis. 10 Ear trauma is a topic that is often neglected. Song et al. help redress this with a detailed study of patients with temporal bone fractures that spare the otic capsule.

“…Bone conduction devices (BCDs) have improved hearing for patients who have hearing loss when conventional air conduction hearing aids are inappropriate [ 1 ]. Conventional BCDs were developed in the beginning of the 20th century with a sound processor attached with spectacles, steel spring headbands, or soft headbands [ 2 ].…”

Objectives. Bone-anchored hearing device (BAHD) is contraindicated in patients younger than 5 years because their calvarial bones are not thick enough to be implanted site. However, it has not been studied in the Korean population. This study was not only to establish a safe guideline for depth of implant device in all age groups who undergo BAHD implant surgery, but also to investigate whether implantation of currently used BAHDs could be done safely in Korean children, especially those younger than 5.Methods. Two hundred eighty patients, who underwent high-resolution temporal bone computed tomography (TBCT) images between August 2010 and October 2018 were randomly enrolled in all ages. We retrospectively reviewed TBCT imaging to measure skull bone thickness at the recommended BAHD implant site.Results. The average skull bone thickness was 2.87 mm in patients younger than 5 years and 6.72 mm in patients older than 5 years, respectively, which conforms to the current guideline. The results indicate nearly 50% of calvarial bone thicknesses were less than 3 mm in patients under 5 years old, while 92.78% of the patients older than 5 years of age showed bone thickness greater than 4 mm. Of note, calvarial bone thickness was thicker than 3 mm in all patients who are older than 6 years.Conclusion. This study confirms that the currently approved BAHD implantation guideline is suitable in the Korean population. For safety, we suggest taking TBCTs prior to surgery, especially in pediatric patients. Besides, noninvasive applications are recommended for patients younger than 5.
