Conclusion
The authors clarify that a change in hearing threshold does not always indicate clinically significant hearing loss.
Supporting Evidence
- A change in hearing threshold of 20 decibels or greater does not imply clinically relevant hearing loss.
- The authors suggest that a change of 40 dB or more is needed for firm evidence of hearing change in younger children.
- There was no overall difference in hearing between right and left ears in the study.
Takeaway
The authors explain that a small change in hearing levels doesn't always mean a child has serious hearing problems.
Methodology
The study used standard methods for audiometry performed by qualified technicians.
Limitations
The study did not use a recognized hearing disability questionnaire or objective measurement of speech discrimination levels.
Participant Demographics
The patients treated with cisplatin were aged 12 and 19 years.
