Sensorineural deafness, also known as nerve-related hearing loss, is a condition that affects the inner ear or the auditory nerve. This article aims to provide you with a clear and concise understanding of sensorineural deafness, including its types, causes, symptoms, diagnostic tests, treatments, and drugs, all explained in simple, everyday language.
Types of Sensorineural Deafness:
- Congenital Sensorineural Deafness: This type of deafness is present at birth and may be due to genetic factors or exposure to infections during pregnancy.
- Acquired Sensorineural Deafness: Acquired deafness occurs after birth and can result from various factors such as aging, exposure to loud noises, or certain illnesses.
Common Causes of Sensorineural Deafness:
- Aging: As we get older, the inner ear’s hair cells can deteriorate, leading to sensorineural deafness.
- Noise Exposure: Loud noises, especially over extended periods, can damage the hair cells in the inner ear.
- Genetics: Some people may inherit genetic mutations that make them more prone to sensorineural deafness.
- Infections: Certain infections, like mumps or meningitis, can damage the inner ear and cause hearing loss.
- Medications: Some drugs, such as certain antibiotics and chemotherapy medications, can harm the auditory nerve.
- Head Trauma: Severe head injuries can damage the inner ear structures and result in hearing loss.
- Tumors: Benign or malignant growths in the ear or on the auditory nerve can cause deafness.
- Cardiovascular Issues: Conditions like high blood pressure and atherosclerosis can affect blood flow to the inner ear.

- Depression or Anxiety: Hearing loss can have emotional and psychological impacts.
- Ear Fullness: A feeling of fullness or pressure in the ear may occur.
- Reduced Awareness of Environmental Sounds: Important sounds like alarms or sirens may be missed.
Common Diagnostic Tests for Sensorineural Deafness:
- Audiometry Test: This test measures your ability to hear sounds of different frequencies and volumes.
- Tympanometry: Tympanometry assesses the function of the middle ear and the mobility of the eardrum.
- Otoacoustic Emissions (OAE) Test: OAE measures the response of the inner ear’s hair cells to sound.
- Auditory Brainstem Response (ABR) Test: ABR evaluates the auditory nerve and brainstem’s response to sounds.
- Speech Audiometry: This test assesses your ability to understand and repeat spoken words.
- Acoustic Reflex Testing: It checks the reflexive response of the middle ear muscles to loud sounds.
- High-Frequency Audiometry: This test evaluates your hearing in the high-frequency range.
- Imaging Tests (CT, MRI): These scans can identify structural issues, like tumors or malformations.
- Electrocochleography (ECoG): ECoG measures electrical activity in the inner ear.
- Vestibular Testing: To assess balance and dizziness issues associated with hearing loss.
- Medical History and Physical Examination: Your doctor will ask about your health and examine your ears.
