How to measure hearing in microtia

Microauricular malformation is a common congenital ear malformation, which not only affects the appearance of patients, but also may affect hearing. Therefore, for patients with microtia, it is very important to carry out hearing test in time. This article will introduce how to conduct hearing test for patients with microtia, and what should be paid attention to during the test.

1、 Methods of listening test

1. Pure tone hearing test Pure tone audiometry is a common hearing test method, which can measure the patient's hearing sensitivity to different frequencies of sounds. During the test, patients need to wear earphones, listen to a series of pure tones with different frequencies, and respond according to the sound intensity heard. The test results can be expressed by audiogram, which can reflect the degree and type of hearing loss of patients.

2. Speech listening test Speech listening test is a test method to measure patients' ability to understand speech. During the test, the patient needs to listen to a series of speech materials and respond according to what they hear. The test results can be expressed by the speech recognition rate, which can reflect the patient's understanding of speech.

3. Auditory evoked potential test Auditory evoked potential test is a test method to evaluate hearing by measuring the brain's response to sound stimuli. During the test, patients need to wear electrodes, listen to a series of sound stimuli, and record the brain's response to sound stimuli. The test results can be represented by the auditory power bitmap, which can reflect the patient's hearing status.

2、 Precautions for listening test

1. Preparation before test Before hearing test, patients need to keep good rest and sleep, and avoid excessive fatigue and drinking. Ears should also be cleaned before testing to ensure the accuracy of test results.

2. Cooperation during testing During the hearing test, the patient needs to keep quiet and avoid talking and moving. The patient also needs to respond to the tester's request, such as pressing a button or raising his hand.

3. Precautions after test After hearing test, patients need to keep their ears clean to avoid ear infection. Patients also need to follow the doctor's recommendations for treatment and rehabilitation training.

3、 Hearing rehabilitation of patients with microtia

1. Wear hearing aid For patients with microtia with mild hearing loss, hearing aids can be worn to improve hearing. Hearing aids can amplify sound and help patients hear sound better.

2. Implantation of cochlear implant For patients with severe hearing loss and microtia, cochlear implant can be considered. Cochlear implant is an electronic device that can convert sound into electrical signals and stimulate auditory nerve through electrodes to help patients recover hearing.

3. Language rehabilitation training For patients with microtia, language rehabilitation training is also very important. Language rehabilitation training can help patients improve their language understanding and expression ability, and improve their quality of life.

4、 Conclusion

Microtia is a common congenital malformation of the ear, which may affect hearing. Therefore, for patients with microtia, it is very important to carry out hearing test in time. Hearing test can help doctors understand the hearing condition of patients and formulate corresponding treatment plans. During the hearing test, patients need to pay attention to the preparation before the test, the cooperation during the test and the precautions after the test. For patients with mild hearing loss, hearing aids can be worn to improve hearing; For patients with severe hearing loss, cochlear implant can be considered. In addition, language rehabilitation training is also very important, which can help patients improve their language understanding and expression ability and improve their quality of life.
