Insights
Sensorineural hearing impairment affects many newborns and adolescents. Innovative treatments like gene therapy and stem cell-derived hair cell regeneration show promise for improved hearing restoration.
Area of Science:
- Otolaryngology
- Genetics
- Regenerative Medicine
Background:
- Sensorineural hearing impairment is common in newborns and adolescents, with over 50% of congenital cases having a genetic origin.
- Monogenic deafness presents potential targets for future gene therapy interventions.
- Current clinical management includes hearing aids, cochlear implants, and speech therapy, but significant unmet needs for hearing restoration persist.
Purpose of the Study:
- To review the pathophysiology of pediatric hearing impairment.
- To provide an update on preclinical developments in innovative hearing restoration approaches.
Main Methods:
- Review of current literature on sensorineural hearing impairment.
- Analysis of advancements in genetic diagnostics, disease modeling, and regenerative medicine.
Main Results:
- Progress in clinical phenotyping, genetic diagnostics, and counseling for hearing impairment.
- Disease modeling in transgenic mice has elucidated genetic hearing impairment mechanisms.
- Preclinical studies indicate upcoming gene therapy trials and next-generation cochlear implants.
Conclusions:
- Gene therapy and advanced cochlear implants are anticipated within the next decade.
- Stem cell-derived sensory hair cells and neurons are advancing disease modeling, drug screening, and regenerative strategies.
- Despite progress, a major clinical need remains for enhanced hearing restoration methods.
Abstract:
Sensorineural hearing impairment is the most frequent form of hearing impairment affecting 1-2 in 1000 newborns and another 1 in 1000 adolescents. More than 50% of congenital hearing impairment is of genetic origin and some forms of monogenic deafness are likely targets for future gene therapy. Good progress has been made in clinical phenotyping, genetic diagnostics, and counselling. Disease modelling, e.g. in transgenic mice, has helped elucidate disease mechanisms underlying genetic hearing impairment and informed clinical phenotyping in recent years. Clinical management of paediatric hearing impairment involves hearing aids, cochlear or brainstem implants, signal-to-noise improvement in educational settings, speech therapy, and sign language. Cochlear implants, for example, have much improved the situation of profoundly hearing impaired and deaf children. Nonetheless there remains a major unmet clinical need for improving hearing restoration. Preclinical studies promise that we will witness clinical trials on gene therapy and a next generation of cochlear implants during the coming decade. Moreover, progress in generating sensory hair cells and neurons from stem cells spurs disease modelling, drug screening, and regenerative approaches. This review briefly summarizes the pathophysiology of paediatric hearing impairment and provides an update on the current preclinical development of innovative approaches toward improved hearing restoration.
