Summary
Children with cystic fibrosis (CF) do not show a higher incidence of middle ear disease or hearing loss compared to the general population. This study evaluated audiological outcomes in CF patients.
Area of Science:
- Otolaryngology
- Pediatrics
- Genetics
Background:
- The middle ear and Eustachian tube mucosa connect to the upper respiratory tract.
- Cystic Fibrosis (CF) commonly affects the paranasal sinuses, suggesting potential middle ear involvement.
- Previous assumptions linked CF to increased middle ear disease risk.
Purpose of the Study:
- To investigate the incidence of middle ear disease in children with cystic fibrosis.
- To compare audiological findings in CF patients with a normal age-adjusted population.
Main Methods:
- Eighty patients diagnosed with cystic fibrosis underwent audiological evaluations.
- Evaluations included hearing threshold levels (250-8,000 Hz), speech audiometry, and impedance audiometry.
Main Results:
- No statistically significant difference in the incidence of conductive hearing loss was observed between CF patients and the control group.
- No statistically significant difference in the incidence of sensorineural hearing loss was observed between CF patients and the control group.
Conclusions:
- Children with cystic fibrosis do not exhibit a higher prevalence of middle ear disease or hearing loss.
- The assumed link between cystic fibrosis and increased middle ear pathology is not supported by audiological data.
