Insights
Simultaneous cochlear and auditory brainstem implantation in children with severe inner ear malformations shows promising audiological progress. This combined approach preserves critical auditory development time for eligible pediatric patients.
Area of Science:
- Otolaryngology
- Pediatric Audiology
- Neurosurgery
Background:
- Severe inner ear malformations pose significant challenges for auditory rehabilitation in pediatric patients.
- Traditional approaches may involve staged implantation, potentially delaying auditory development.
Purpose of the Study:
- To evaluate the initial surgical and audiological outcomes of simultaneous cochlear implantation (CI) and auditory brainstem implantation (ABI) in pediatric patients.
- To assess the efficacy of combined CI and ABI in children with severe inner ear malformations.
Main Methods:
- Retrospective case review of three pediatric patients (ages 1.9-2.5 years) with severe inner ear malformations.
- Simultaneous implantation of a CI in one ear and an ABI in the contralateral ear.
- Evaluation of free-field thresholds with each device individually and in combination.
Main Results:
- All patients demonstrated good audiological progress with both devices, as indicated by free-field thresholds.
- One patient experienced slower progress, potentially attributed to comorbid CHARGE syndrome.
- Surgical outcomes were also reviewed, with no specific complications detailed in the abstract.
Conclusions:
- Simultaneous CI and ABI is a viable therapeutic option for pediatric patients with severe inner ear malformations requiring both devices.
- This combined approach optimizes auditory development by avoiding delays associated with staged procedures.
- The findings support the use of simultaneous implantation to maximize auditory potential in this patient population.
Objective:
To report the initial surgical and audiological outcomes of three pediatric patients with severe inner ear malformations who were simultaneously implanted with cochlear and brainstem implants in the same surgical session.
Study Design:
Retrospective case review.
Setting:
Tertiary referral center.
Patients:
Three pediatric patients with severe inner ear malformations between ages of 1.9 to 2.5 years, who were simultaneously implanted with cochlear implant in one ear and auditory brainstem implant in the other ear.
Intervention(S):
Simultaneous application of cochlar implant in one ear, auditory brainstem implant in the other ear.
Main Outcome Measures:
Free field thresholds with cochlear and brainstem implants. Surgical issues are also discussed.
Results:
The study is descriptive in nature. Free field thresholds with each device alone and together showed good progress. One of the patients had slower progress possibly due to comorbid CHARGE syndrome.
Conclusions:
The results showed good progress in terms of audition with both devices. Simultaneous cochlear and brainstem application serves as a remedy for pediatric patients who are candidates for cochlear implant on one side and brainstem implant on the other side. With this simultaneous application precious time for auditory development is not lost.
