Idiopathic progressive sensorineural hearing loss in children

Area of Science:

• Pediatrics
• Audiology
• Otolaryngology

Background:

• Bilateral idiopathic progressive sensorineural hearing loss is a significant pediatric concern.
• Understanding onset age and audiologic characteristics is crucial for early intervention.
• Potential links between hematological factors and hearing loss require further investigation.

Purpose of the Study:

• To analyze the distribution of onset age in pediatric sensorineural hearing loss.
• To characterize audiologic features and their relation to age at onset.
• To explore possible correlations between hearing loss and hematochemical alterations.

Main Methods:

• Clinical observations of 42 children diagnosed with bilateral idiopathic progressive sensorineural hearing loss.
• Patients categorized into two groups based on age of hearing loss onset (0-6 years and 7-14 years).
• Audiometric features, audiologic characteristics, and hematochemical tests were analyzed.

Main Results:

• A peak onset age for hearing loss was observed between 4-6 years.
• A 'descending' hearing loss curve with recruitment was common.
• Hematochemical tests indicated a possible correlation between hearing loss and anemia.
• No significant difference in incidence was found between sexes.

Conclusions:

• The study highlights a common age range for the onset of progressive sensorineural hearing loss in children.
• Audiologic patterns like descending curves with recruitment are prevalent.
• Anemia may be a contributing factor, warranting further research.
• Hearing loss affects both sexes equally in this cohort.
