Cochlear Implantation in children with CHARGE syndrome

Area of Science:

• Otolaryngology
• Genetics
• Pediatrics

Background:

• CHARGE syndrome is a rare genetic disorder characterized by multiple congenital anomalies affecting various systems, including the auditory pathway.
• Sensorineural hearing loss is common in CHARGE syndrome, often profound, necessitating advanced auditory interventions.
• Cochlear implantation is explored as a therapeutic option for significant hearing loss in these patients.

Observation:

• A chart review of three pediatric cases with CHARGE syndrome and profound sensorineural hearing loss was conducted.
• One patient had a prior unsuccessful cochlear implantation due to non-auditory stimulation.
• All three patients underwent successful cochlear implantation with Nucleus Freedom Implants.

Findings:

• Patients demonstrated improved audiological function post-implantation.
• Outcomes included development of verbal communication, enhanced speech quality, and improved speech reading.
• One child achieved reliable sound response and phrase comprehension, though limited by tracheostomy.

Implications:

• Cochlear implantation presents challenges in CHARGE syndrome but offers significant potential for audiological and quality of life improvements.
• Appropriate patient selection is crucial for optimizing success rates.
• This study highlights the benefits of cochlear implantation in improving communication and auditory function in children with CHARGE syndrome.
