Profile of patients assessed for cochlear implants

Area of Science:

• Audiology
• Pediatrics
• Public Health

Background:

• Understanding profound hearing loss characteristics is crucial for diagnosis, prognosis, and public health planning.
• Early identification and intervention are key for optimal outcomes in children with hearing loss.

Purpose of the Study:

• To investigate the etiologies of sensorineural hearing loss.
• To determine the age of hearing loss diagnosis and its impact on language acquisition.
• To analyze the age at first consultation for cochlear implant assessment.

Main Methods:

• Retrospective analysis of 115 patient records with sensorineural hearing loss.
• Historical cohort, cross-sectional study design.
• Data collected on gender, age of hearing loss onset, age at first consultation, language development, and etiology.

Main Results:

• Most patients seeking cochlear implants are referred after one year of age, with a mean of 3.8 years for the prelingual group.
• Early diagnosis of hearing loss is often followed by delayed referral for intervention.
• Idiopathic causes are most frequent, followed by perinatal factors and meningitis.

Conclusions:

• Significant delays in healthcare referrals for cochlear implant assessment are evident.
• The current healthcare system demonstrates deficiencies in timely patient referral for hearing loss intervention.
• Perinatal causes and meningitis are significant known etiologies of hearing loss in the studied population.
