Summary
Cochlear implants can significantly benefit congenitally deaf adolescents, even with prolonged deafness. Individual assessment is crucial for determining prognosis and potential speech perception improvements.
Area of Science:
- Audiology
- Otolaryngology
- Neuroscience
Background:
- Prognosis for cochlear implantation in adolescents with congenital deafness and long-term profound hearing loss is typically poor.
- Previous research indicates limited speech perception benefits for this demographic.
Purpose of the Study:
- To evaluate speech perception outcomes in two congenitally deaf adolescents following cochlear implantation.
- To determine if significant benefits can be achieved despite a long duration of deafness.
Main Methods:
- Adolescents with congenital deafness underwent cochlear implantation.
- Speech perception was assessed after 12 months of device use, without lip-reading assistance.
Main Results:
- Both patients achieved significant open-set speech discrimination scores.
- These results indicate substantial improvements in speech perception after a relatively short period.
Conclusions:
- While general prognosis may be low, individual congenitally deaf adolescents can experience significant benefits from cochlear implants.
- Patient selection for cochlear implantation should be individualized based on specific prognostic factors.
