What is an Audiogram?
An
audiogram is a graphical representation of a person's hearing ability. It measures the softest sounds an individual can hear at different frequencies, typically ranging from low to high pitches. Audiograms are essential tools used by audiologists to diagnose and monitor hearing loss. In the context of cancer, audiograms can become particularly important due to the potential
side effects of certain cancer treatments.
When Should Cancer Patients Have an Audiogram?
It is recommended that cancer patients undergo a baseline audiogram before starting treatment with known ototoxic agents. Follow-up audiograms should be conducted regularly during and after treatment to monitor any changes in hearing ability. This proactive approach allows for timely intervention, potentially minimizing long-term hearing damage.
How is an Audiogram Conducted?
The process of conducting an audiogram is straightforward and non-invasive. The patient wears a pair of headphones and listens to a series of tones at different frequencies and volumes. They indicate when they can hear a sound, and their responses are recorded on an audiogram chart. This chart helps audiologists identify the degree and type of hearing loss, which can be categorized as
conductive,
sensorineural, or mixed.
Conducting baseline and follow-up audiograms.
Identifying early signs of hearing loss.
Collaborating with oncologists to adjust treatment plans if necessary.
Recommending and fitting hearing aids or other assistive devices.
Providing counseling and support to patients and their families.
Conclusion
Audiograms are vital in the context of cancer care as they help in the early detection and management of hearing loss caused by ototoxic treatments. Regular hearing assessments, timely interventions, and a multidisciplinary approach involving audiologists are crucial in ensuring the overall well-being and quality of life of cancer patients.
