To compare the effectiveness of implanted and non-implanted hearing solutions on subjective hearing disability and health-related quality of life in adults with acquired single-sided deafness.
Methods
This systematic review adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines and was registered in the Prospective Register of Systematic Reviews. Multiple databases were searched from January 1965 to October 2025 for studies reporting patient-reported hearing disability and health-related quality of life utility measures with cochlear implants, bone-conduction devices and contralateral routing of signal hearing aids as single-sided deafness treatments.
Results
Pooled analysis of 13 studies (403 participants) demonstrated improved hearing disability scores with implanted solutions compared with no intervention [mean difference = −14.71 (95% CI: −23.48, −5.93), p < 0.00001]. Non-implanted bone-conduction devices demonstrated lower hearing disability than contralateral routing of signal aids [mean difference = 4.70 (95% CI: 0.27, 9.14); p = 0.04]. Cochlear implants significantly improved health-related quality of life compared with no hearing solution [mean difference = 0.21 (95% CI: 0.10, 0.31); p = 0.0001].
Conclusion
Single-sided deafness patients reported greater mean hearing-related improvement with implanted than non-implanted hearing solutions.
Chapter 1 is set on August 28, 1963, the date of the March on Washington. It introduces readers to two characters who will play critical roles in the St. Augustine civil rights drama.
One is Irwin Brunson, a fourth grader who becomes one of five pioneer Black integrators of St. Augustine public schools that fall. August 28th happens to be registration day—meaning it is the first day he sets foot in the Fullerwood Elementary School. Later that day, Irwin watches the coverage from the March on Washington with his siblings and his parents, both of whom are deaf. It is a day of adventure and excitement, but the beginning of an utterly harrowing year.
The other is Kathy Fentress, a 19-year-old rising sophomore at Duke University who grew up an hour south of St. Augustine in Ormond Beach. Kathy, who had participated in some of the first civil rights protests in St. Augustine that summer, takes a bus up to Washington to attend the March. She is the only white person on that bus. It proves a day of unparalleled inspiration for her, but she, too, is set up for a very challenging year ahead.
This chapter examines the central role of Christianity in shaping early modern understandings of deafness. It demonstrates that while the Church was responsible for promoting deaf inclusion, it was also a powerful source of enduring prejudice about deafness. Across England and Europe, clerics routinely enabled deaf people to marry, make confession, and receive the Eucharist using sign language. This acceptance of sign language as a legitimate alternative to speech had significant legal implications, enabling people to demonstrate their rational capacity. Ecclesiastical acceptance promoted the idea that deaf people were legally capable, able to consent, testify, and participate fully in early modern society. Yet the Church also generated some of the most damaging and long-lived ideas about deafness. The association of hearing with spiritual growth meant that deaf people continued to face prejudice throughout the period. The chapter argues that this tension between inclusion and suspicion defined the early modern religious experience of deaf people: it also suggests that encounters with deaf people changed contemporary perceptions about the sensory nature of salvation.
Sentio™ is novel transcutaneous implantable conductive hearing device. Evidence in paediatric populations, particularly syndromic children, remains limited. We report our local experience in paediatric patients, including syndromic cases.
Methods
A prospective case series of patients implanted between March 2025 and February 2026 was reviewed. Data collected included demographics, underlying pathology, subjective outcomes (Children’s Home Inventory for Listening Difficulties), objective outcomes (Bamford–Kowal–Bench) and surgical outcomes.
Results
Four patients (median age, 13.7 years; range, 11–15.5 years) were implanted, with one bilateral case. There was subjective and objective audiological improvement except for one patient, probably caused by poor concentration. Surgical learning points include the use of a longer fixation band to compensate for shallower drilling, careful implant positioning in microtia patients to facilitate future reconstruction and the use of image-guided navigation to avoid previous craniofacial surgery drill holes.
Conclusion
Sentio™ demonstrated favourable audiological and surgical outcomes in paediatric patients, including those with syndromes.
The role of the intermediary in legal proceedings in England and Wales is traced back to a recommendation in 1989 that there should be an ‘interlocutor’ for vulnerable people involved in criminal proceedings. This article sets out the statutory and procedural provisions for the appointment and deployment of intermediaries. The functions of the intermediary in legal proceedings are described and illustrated with cases from the authors’ experiences and legal judgments handed down in criminal, family and immigration and asylum proceedings. Suggestions are made as to how psychiatrists can best assist the courts when it is considered that the appointment of an intermediary is necessary. Attention is drawn to the importance of psychiatrists, psychologists and intermediaries working collaboratively with each other and with other professionals in order that vulnerable people who have communication difficulties, whether as a result of age, some form of mental disorder, intellectual disability, deafness or for some other reason, can be assisted so as to participate effectively and without disadvantage in legal proceedings.
In the previous chapter we looked at how we use and understand language, now let’s look at the ways that people lose language and also experience language difficulties of various kinds. These aren’t the normal errors and mistakes we’ve already discussed, but are the result of disability, disease, disorder, brain injury, and other factors that can affect speech use and understanding and further impair the ability to read and write. In the US alone, between five to ten percent of the population have various types of communication disorders. The figures are even higher for learning disorders such as dyslexia. All in all, this amounts to millions of people who live with language differences. This chapter discusses how both developmental and acquired disorders affect language processing and production.
Disability is an unspoken aspect that is overshadowed by larger issues in Aboriginal and Torres Strait Islander education. Young Aboriginal and/or Torres Strait Islander people with a disability often fall through the cracks in the education system, with their disability not recognised or not supported. The presentation of their disability in the classroom is routinely mis-characterised as behavioural issues rather than a learning disability requiring specific support, an assumption that leads to excessively high rates of suspension and expulsion when disability is a factor in the education of Aboriginal and/or Torres Strait Islander children and young people.
This article focuses on the use of the terms “deaf” and “deaf-mute” in the interwar Romanian press to explore the multiplicity of meanings attached to this condition in different types of public discourse. My aim is to place in the larger context of that period what meanings become most prominent in newspapers and other forms of popular press, why, and with what consequences. I offer an exploration of these discourses to better appreciate how the reading public, both able-bodied and disabled, saw disability represented. Rendering the very multiplicity of meanings attached to “deafness” visible in the relevant context is an important goal for this essay; it allows us to better understand the continued imprecision and stigmatizing framework in how Romanian society engaged with the deaf. I also explore what space existed for the deaf community to shape their own self-representations. Placing ableist discourses in dialogue with the voices of the deaf community is an important aim, as a method to de-essentialize the predominant ableist discourses and normalize accounting for disability as a significant element of modern history.
Early language development has rarely been studied in hearing children with deaf parents who are exposed to both a spoken and a signed language (bimodal bilinguals). This study presents longitudinal data of early communication and vocabulary development in a group of 31 hearing infants exposed to British Sign Language (BSL) and spoken English, at 6 months, 15 months, 24 months and 7 years, in comparison with monolinguals (exposed to English) and unimodal bilinguals (exposed to two spoken languages). No differences were observed in early communication or vocabulary development between bimodal bilinguals and monolinguals, but greater early communicative skills in infancy were found in bimodal bilinguals compared to unimodal bilinguals. Within the bimodal bilingual group, BSL and English vocabulary sizes were positively related. These data provide a healthy picture of early language acquisition in those learning a spoken and signed language simultaneously from birth.
Deafness is a leading cause of disability worldwide. This prospective cohort study investigates the impact of cochlear implants on self-reported quality of life in post-lingually deaf adults.
Methods
The self-administered 36-item World Health Organization Disability Assessment Schedule 2.0 and the Speech, Spatial, and Qualities of Hearing Scale questionnaires were prospectively used to investigate the impact of cochlear implants in 98 post-lingually deaf adults aged more than or equal to 50 years.
Results
Quality of life improved post-cochlear implant in the cumulative scores and scores for all domains of the Speech, Spatial, and Qualities of Hearing Scale (p < 0.05). QoL improved post-cochlear implant in the sub-domains related to cognition and participation in society of the World Health Organization Disability Assessment Schedule 2.0 (p < 0.05), but there was no significant difference in the cumulative score. Subgroup analysis showed improvement in the participation in society domain only and only in males and participants aged younger than 75 years (p < 0.05).
Conclusion
Cochlear implant improves quality of life in post-lingually deaf adults.
In this study, our objective was to explore the impact of hearing loss on the conceptual system underlying word meaning. We collected perceptual strength norms for 200 Italian words from early deaf individuals with limited or no access to auditory information and compared them to existing norms from hearing individuals. For each word, participants provided perceptual strength ratings for each perceptual modality. Our results revealed a significant reduction of the auditory modality in the norms provided by deaf individuals compared to the hearing population. However, we did not observe an overall decrease in reported perceptual strength. Interestingly, we found a heightened involvement of other sensory modalities accompanied by reduced modality exclusivity in the conceptualization of words, indicating that deaf individuals heavily rely on information coming from the other perceptual modalities to form concepts. These findings suggest that hearing loss leads to a reorganisation of word conceptualization, characterised by increased multisensoriality. Importantly, although diminished, the auditory modality remains present, suggesting that deaf individuals can still infer auditory-associated knowledge about words to some extent.
Executive functions (EFs) in both regulatory and meta-cognitive contexts are important for a wide variety of children’s daily activities, including play and learning. Despite the growing literature supporting the relationship between EF and language, few studies have focused on these links during everyday behaviours. Data were collected on 208 children from 6 to 12 years old of whom 89 were deaf children (55% female; M = 8;8; SD = 1;9) and 119 were typically hearing children (56% female, M = 8;9; SD = 1;5). Parents completed two inventories: to assess EFs and language proficiency. Parents of deaf children reported greater difficulties with EFs in daily activities than those of hearing children. Correlation analysis between EFs and language showed significant levels only in the deaf group, especially in relation to meta-cognitive EFs. The results are discussed in terms of the role of early parent–child interaction and the relevance of EFs for everyday conversational situations.
Scientific and technical words in Astronomy are often absent in many sign languages. To alleviate this problem, we present the first online dictionary which includes a comparative list of signs which can be used especially in sign language for countries in which they have not been yet defined. After a brief summary of the history and evolution of the sign language in France, we show that many common signs can be adopted as universal, taking into account the individual heritage of each country.
Over the last 10 years or so, I have noticed increasing trouble understanding what people are saying to me, especially if there are several people speaking at the same time, such as at a family dinner, or worse, at a big party. It may be the main reason I find social occasions increasingly difficult and intimidating. When Lois speaks to me, I often have to ask her to repeat what she said. She has learned to say things twice if she wants me to get it. I know that is irritating for her. Often, I just nod or grunt, pretending I understand what she is saying. I have attributed this increasing problem to my Alzheimer’s disease interfering with my ability to understand language, particularly if I don’t hear every word clearly. Aphasias affecting language production (poor word finding) or reception (impaired understanding) are common in the mid-to-late stages of Alzheimer’s, but trouble finding the right word or name is often one of the earliest symptoms of Alzheimer’s.
Children who receive cochlear implants develop spoken language on a protracted timescale. The home environment facilitates speech-language development, yet it is relatively unknown how the environment differs between children with cochlear implants and typical hearing. We matched eighteen preschoolers with implants (31-65 months) to two groups of children with typical hearing: by chronological age and hearing age. Each child completed a long-form, naturalistic audio recording of their home environment (appx. 16 hours/child; >730 hours of observation) to measure adult speech input, child vocal productivity, and caregiver-child interaction. Results showed that children with cochlear implants and typical hearing were exposed to and engaged in similar amounts of spoken language with caregivers. However, the home environment did not reflect developmental stages as closely for children with implants, or predict their speech outcomes as strongly. Home-based speech-language interventions should focus on the unique input-outcome relationships for this group of children with hearing loss.
This chapter has three parts. In the first, the author concentrates on the deaf bilingual and explains what it means to be bilingual in sign language and the spoken (majority) language. Similarities with hearing bilinguals as well as differences are discussed. In the second part, he examines the biculturalism of deaf people: like hearing biculturals, they take part, to varying degrees, in the life of two worlds (the deaf world and the hearing world), they adapt, in part, their attitudes, behaviors, values, languages, and so onto both worlds, and they combine and blend aspects of the two. He also discusses cultural identity among deaf and hard-of-hearing persons. And in the third part, the author considers the deaf child and why it is so important for him/her to be able to grow up bilingual in sign language and the spoken language. He points to the role of both languages and argues that pursuing solely an auditory/oral approach puts the child at risk cognitively, linguistically, and personally. He ends by examining the reactions his writings have had on the field, and concludes with a few final remarks.
François Grosjean is one of the world's best-known scholars in the study of bilingualism. Over a career spanning two continents, his holistic approach has made groundbreaking contributions to many areas of the field. This book surveys this lifetime of work, from the start of his career, to where it stands today. The first chapter sets the stage with his personal experience as a bilingual, and the chapters that follow then deal with his holistic view of bilingualism, the bilingual's language modes, the Complementarity Principle, spoken language processing, cross-linguistic influence, biculturalism, the bilingualism and biculturalism of the Deaf, the statistics of bilingualism, and special bilinguals. In each chapter, he describes the concept, theory or findings that he proposed, adds follow-up comments, and discusses reactions, replications and extensions. The final chapter underlines the importance of informing the general public about bilingualism and biculturalism, and illustrates how this can be done.
With the United States’ entrance into the First World War, linguistic and cultural cohesiveness became imperative, compelling everyone—from immigrants with foreign accents to people with speech problems and hearing loss—to “sound American” by fluently speaking the language of their flag.
This article examines lip-reading, speech, and auricular training prescribed to deaf and hard-of-hearing children as well as for servicemen deafened in the war to demonstrate how World War I demanded all Americans to contribute to and participate in shared national soundscapes, regardless of their hearing status. Use of American Sign Language was considered a conspicuous sign of one’s failure to integrate into hearing society, and it shared parallels with immigrants who failed to learn English and fully assimilate into American culture. Indeed, rehabilitation of deafened soldiers of the First World War through speech training and lip-reading instruction at Hospital No. 11 at Cape May, New Jersey, coincided with broader national efforts to improve Americans’ speech and language use, and in turn, their patriotism and productivity.
This article discusses speech and hearing disabled Americans’ claims to citizenship during World War I, and the ways American policymakers sought to rehabilitate American soldiers treated in the U.S. Army Section of Defects of Hearing and Speech—or those classified after the Section’s closure as deaf, hard-of-hearing, or “speech defective.” Ultimately, I argue that one’s aural communication abilities were indicators of worthiness in American society and that this was especially the case during World War I, when tensions about speech and hearing heightened within and outside of the Deaf community due to significant pressures placed on Americans to show support for the war. Such pressures also shaped the experiences of American soldiers treated for speech and hearing disabilities after 1918, by suggesting that their service to the United States could not be complete until they were successfully rehabilitated through lip-reading training. To be able to aurally communicate signified the veterans’ sound citizenship in a literal and a metaphorical sense.
