Insights
This study observed 42 children with progressive sensorineural hearing loss, finding a peak onset age between 4-6 years. A potential link between hearing loss and anemia was suggested, with no significant sex-based incidence difference.
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.
Abstract:
Clinical observations were made of 42 children with bilateral idiopathic progressive sensorineural hearing loss considering hearing loss distribution in relation to age at onset, audiometric features, audiologic characteristics and possible correlation with some haematochemical alterations. Patients were divided into 2 groups on the basis of hearing onset: Group I, 0-6 years; Group II, 7-14 years. A peak in the distribution of onset age was observed in the range of 4-6 years. In most cases a 'descending' curve was recognized accompanied by recruitment. The haematochemical tests only suggested a possible correlation between hearing loss and anaemia. Finally, no significant difference of incidence between the sexes was observed.
