Speech Audiometry - Cancer Science

What is Speech Audiometry?

Speech audiometry is a diagnostic hearing test used to assess an individual's ability to hear and understand speech. It is a critical component in the evaluation of hearing function, especially in patients with cancer who may experience hearing loss due to the disease itself or as a side effect of treatments such as chemotherapy and radiation therapy.

Why is Speech Audiometry Important for Cancer Patients?

Cancer treatments can have ototoxic effects, meaning they can damage the ear and impair hearing. Drugs like cisplatin and carboplatin, as well as radiation to the head and neck, can affect the auditory system. Monitoring hearing through speech audiometry helps in early detection of hearing loss, allowing for timely intervention and management.

How is Speech Audiometry Conducted?

The test typically involves the patient listening to and repeating back a series of words presented at different volumes. Two primary measures are assessed: the speech reception threshold (SRT) and the word recognition score (WRS). The SRT determines the faintest speech that can be heard half the time, while the WRS evaluates the clarity of speech understood at a comfortable loudness level.

What are the Potential Effects of Cancer Treatments on Hearing?

Ototoxicity from cancer treatments can lead to a range of hearing issues, including tinnitus (ringing in the ears), sensorineural hearing loss, and difficulties in understanding speech in noisy environments. These effects can significantly impact a patient's quality of life, making regular auditory assessments essential.

How Can Hearing Loss Be Managed in Cancer Patients?

Management strategies may include the use of hearing aids, cochlear implants, or other assistive listening devices. Audiologists may also recommend auditory rehabilitation programs to help patients adapt to changes in their hearing. In some cases, modifying the cancer treatment plan may be necessary to minimize further auditory damage.

Who Should Be Involved in the Management of Hearing Loss in Cancer Patients?

A multidisciplinary approach is often required, involving oncologists, audiologists, ENT (ear, nose, and throat) specialists, and primary care physicians. Collaboration among these healthcare providers ensures comprehensive care, addressing both the cancer and its side effects on hearing.

What Are the Benefits of Early Detection of Hearing Loss in Cancer Patients?

Early detection through speech audiometry allows for prompt intervention, which can prevent further deterioration of hearing and improve communication abilities. This proactive approach can significantly enhance the overall quality of life for cancer patients, enabling them to remain socially active and engaged.

Are There Any Risks Associated with Speech Audiometry?

Speech audiometry is a non-invasive and safe procedure with no associated risks. It is a valuable tool in the ongoing care and monitoring of cancer patients, offering critical insights into their auditory health without causing any harm.

Conclusion

Speech audiometry plays a vital role in the care of cancer patients, providing essential information about their hearing abilities. Given the potential ototoxic effects of cancer treatments, regular auditory assessments are crucial for early detection and management of hearing loss, ensuring better overall outcomes and quality of life.
