“…Treatment is available for this group of patients from early childhood with bone conduction devices (BCDs), and later middle ear implant or reconstruction of the external ear canal and middle ear in selected cases. Fitting of BCD in adulthood does not seem to restore binaural hearing fully [5,6] but results of hearing treatment from early childhood with BCD are promising [19] which might reflect the importance of early treatment. Compliance to treatment with conventional BCDs is however low [9], the major cause given was too little benefit from the device.…”

Background: Individuals with unilateral hearing loss show poor spatial hearing, but individual variability is high. Aims/objectives: To investigate if the degree of hearing loss in unilateral ear canal atresia affects horizontal sound localization and speech recognition. Materials and methods: Twelve subjects with unilateral ear canal atresia without childhood hearing intervention. Previously published data from eight normal-hearing subjects in normal binaural as well as experimentally induced unilateral hearing loss served as a reference. Horizontal sound localization and recognition of speech in spatially separate competing speech were assessed.Results: Linear regression analysis demonstrated a relationship between sound localization accuracy (SLA) and the air conduction pure tone average of the atretic ear (r ¼ 0.85, p¼.007). The large proportion of variability in SLA (72%) explained by the degree of hearing loss of the atretic ear indicates that binaural processing is possible. SLA was worse than for normal hearing individuals (p<.0001), and comparable to moderate simulated unilateral hearing loss (p¼.13). Speech discrimination was significantly worse than normal (p<.0001) and not dependent on degree of hearing loss of the atretic ear. Conclusions and significance: Individuals with congenital unilateral ear canal atresia show impaired horizontal SLA and recognition of speech in competing speech.

“…There was also documentation of improved QOL functional outcomes as measured by the CHILD. Liu et al also performed a systematic review evaluating the role of bone conduction aids [ 37 ]. They, too, found consistent gain in SRT and speech discrimination, but inconsistent results with sound localization.…”

Purpose of ReviewThe aim of this study is to summarize the consequences of permanent unilateral hearing loss (UHL) on the development of children as documented in the recent literature.Recent FindingsCongenital and early-identified UHL places young children at risk for delays in speech-language development. School-aged children with UHL score lower on standardized tests of language and cognition and need increased assistance in school for educational and behavioral issues than siblings with normal hearing, and report lower hearing-related quality of life, similar to children with bilateral hearing loss (HL). Early intervention, including use of hearing amplification devices, might ameliorate some of those affects. For a child with mild to severe UHL at presentation, the risk of progression of HL in the worse-hearing ear may be as high as 40%, and the risk of progression to bilateral HL approaches 20%.SummaryAlthough UHL can adversely affect the development of children, how to mitigate those effects requires investigation.

“…Educational problems, deficits in hearing skills, behavioral disorders, and communication barriers resulting from hearing impairment are the most common factors disrupting the proper development of this group of children. They have a particular impact on a young child, for whom the first years of life are the period of acquiring aural and linguistic skills and improving communication [ 17 , 25 – 28 ].…”

Effectiveness of Bone Conduction Hearing Aids in Young Children with Congenital Aural Atresia and Microtia

Background The aim of this study was to assess the effectiveness of bone conduction hearing aids in children under 2 years old who have congenital microtia and atresia. Material/Methods This prospective study involved 42 children under 2 years old with congenital microtia and atresia who were divided into 2 groups: 21 with unilateral defect and 21 with bilateral defect. All children were provided with bone conduction hearing aids on a softband. Air and bone auditory thresholds were assessed by auditory brainstem responses (ABRs). The LittlEARS questionnaire was used to evaluate auditory development at baseline and after 6 months of hearing aids use. Behavioral observation audiometry (BOA) was used to assess auditory thresholds and compare aided and unaided hearing. Results After 6 months of hearing aid use, the total score of the LittlEARS questionnaire in children with unilateral defect was 24±5.60, while children with bilateral defect achieved a result of 26.29±6.17. Hearing thresholds in both groups with bone conduction hearing aids improved significantly and approached the normal level. Conclusions Our results confirm that bone conduction hearing aids provide an effective method of auditory rehabilitation for children with conductive and mixed hearing loss caused by microtia and atresia. Using bone conduction hearing aids in such children is crucial for proper hearing, speech, and language development.
