“…4,26 The central auditory system can selectively suppress the impact of noise and improve speech perception when there is binaural hearing input from different directions. This phenomenon is called the binaural squelch effect, 19 whereas binaural summation is the integration of the acoustic signal by the central auditory system, improving the perceptual loudness of the acoustic signal when hearing binaurally.…”

“…Additionally, binaural benefits could be related to the duration of auditory deprivation, asymmetrical degeneration in binaural neural pathways and maturation of binaural temporal processing in the auditory cortex. 19 Wieringen et al discussed the neural processing of adults and children and highlighted that children's brains were highly sensitive to the loss of auditory input and that the growth and development of the cerebral cortex among these patients are diverse according to the varying degrees of congenital and acquired unilateral deafness as a result of imbalanced auditory input. 2 The results of the present study further demonstrated the short-and long-term performance of Bonebridge implantation in patients with single-sided deafness.…”

“…1,4,6,18 Similarly, some children with single-sided deafness have obtained significant audiological and subjective benefits from cochlear implantation. 4,5,19 Unlike the contralateral routing of signal and BAHA devices, cochlear implantation helps patients with single-sided deafness obtain bilateral input and restores bilateral hearing, rather than simply transmitting sound signals to the normal ear. 1,4 However, patients with single-sided deafness who received cochlear implantation experienced different stimulation of their ears when electrical and acoustic stimulations arose from their impaired ear and normal-hearing ear separately.…”

Objective This study aimed to investigate the benefit of Bonebridge devices in patients with single-sided deafness. Method Five patients with single-sided deafness who were implanted with Bonebridge devices were recruited in a single-centre study. Participants’ speech perception and horizontal sound localisation abilities were assessed at 6 and 12 months post-operatively. Speech intelligibility in noisy environments was measured in three different testing conditions (speech and noise presented from the front, speech and noise presented from the front and contralateral (normal ear) side separately, and speech presented from the ipsilateral (implanted Bonebridge) side and noise from the contralateral side). Sound localisation was evaluated in Bonebridge-aided and Bonebridge-unaided conditions at different stimuli levels (65, 70 and 75 dB SPL). Results All participants showed a better capacity for speech intelligibility in quiet environments with the Bonebridge device. The speech recognition threshold with the Bonebridge device was significantly decreased at both short- and long-term follow up in the speech presented from the ipsilateral (implanted Bonebridge) side and noise from the contralateral side condition (p < 0.05). Additionally, participants maintained similar levels of sound localisation between the Bonebridge-aided and unaided conditions (p > 0.05). However, the accuracy of localisation showed some improvement at 70 dB SPL and 75 dB SPL post-operatively. Conclusion The Bonebridge device provides the benefit of improved speech perception performance in patients with single-sided deafness. Sound localisation abilities were neither improved nor worsened with Bonebridge implantation at the follow-up assessments.

“…Bimodal localization abilities are highly variable with conflicting reports regarding bimodal benefit. Specifically, some studies have demonstrated significant bimodal benefit for horizontal plane localization (e.g., Choi et al, 2017;Potts et al, 2014) and other studies have shown little-tono benefit over unilateral hearing alone (e.g., Dorman et al, 2016;Potts & Litovsky, 2014).…”

Objective: The objectives of this study were to assess the effectiveness of various measures of speech understanding in distinguishing performance differences between adult bimodal and bilateral cochlear implant (CI) recipients and to provide a preliminary evidence-based tool guiding clinical decisions regarding bilateral CI candidacy. Design: This study used a multiple-baseline, cross-sectional design investigating speech recognition performance for 85 experienced adult CI recipients (49 bimodal, 36 bilateral). Speech recognition was assessed in a standard clinical test environment with a single loudspeaker using the minimum speech test battery for adult CI recipients as well as with an R-SPACE™ 8loudspeaker, sound-simulation system. All participants were tested in three listening conditions for each measure including each ear alone as well as in the bilateral/bimodal condition. In addition, we asked each bimodal listener to provide a yes/no answer to the question, "Do you think you need a second CI?" Results: This study yielded three primary findings: 1) there were no significant differences between bimodal and bilateral CI performance or binaural summation on clinical measures of speech recognition, 2) an adaptive speech recognition task in the R-SPACE™ system revealed significant differences in performance and binaural summation between bimodal and bilateral CI users, with bilateral CI users achieving significantly better performance and greater summation, and 3) the patient's answer to the question, "Do you think you need a second CI?" held high sensitivity (100% hit rate) for identifying likely bilateral CI candidates and moderately high specificity (77% correct rejection rate) for correctly identifying listeners best suited with a bimodal hearing configuration. Conclusions: Clinics cannot rely on current clinical measures of speech understanding, with a single loudspeaker, to determine bilateral CI candidacy for adult bimodal listeners nor to accurately document bilateral benefit relative to a previous bimodal hearing configuration. Speech recognition in a complex listening environment, such as R-SPACE™, is a sensitive and appropriate measure for determining bilateral CI candidacy and also likely for documenting bilateral benefit relative to a previous bimodal configuration. In the absence of an available R-SPACE™ system, asking the patient whether or not s/he thinks s/he needs a second CI is a highly sensitive measure which may prove clinically useful.

Введение. Кохлеарная имплантация является на сегодня наиболее результативным способом слухоречевой реабилитации детей с выраженными формами сенсоневральной тугоугости и глухотой, но остается ряд дискутабельных вопросов, касающихся сроков проведения оперативного вмешательства и моно-и билатерального варианта имплантации. Цель исследования-оценить отдаленные результаты слухоречевой реабилитации при моно-и билатеральной кохлеарной имплантации у детей в зависимости от сроков проведения оперативного вмешательства. Методы. Использованы критерии балльной оценки слухоречевой реабилитации «Языкового этапа развития восприятия речи и формирования собственной речи» и «Этапа развития понимания связной речи и сложных текстов» у детей с моно-и билатеральной кохлеарной имплантацией. В ретроспективном исследовании использованы результаты слухоречевой реабилитации 98 пациентов по истечению длительного периода после проведенного оперативного вмешательства. Детальный анализ показателей, характеризующих владение основными компонентами языковой системы и устной речью, был проведен по 12 критериям освоения навыков при участии психоневрологов и сурдопедагогов. Статистические расчеты по результатам оценки слухоречевой реабилитации выполнены в программе Excel 2010 MS. Результаты. Анализ результатов слухоречевой реабилитации у детей при билатеральной кохлеарной имплантации, оцененный в отдаленном периоде в соответствии с критериями «Языкового этапа развития восприятия речи» позволил продемонстрировать, что такие навыки, как развитие слуховой памяти, накопление активного (экспрассивного) словаря, развитие диалогической речи и совершенствование голосового контроля, более чем на 50% положительно отличают возрастную группу прооперированных до 3-летнего возраста. Для пациентов с монолатеральной кохлеарной имплантацией отличительными признаками слухоречевой реабилитации выступили дополнительно развитие понимания устной речи слухо-зрительно и на слух и развитие связной речи 4.0
