What is the Difference Between Sensorineural and Conductive Hearing Loss?
🆚 Go to Comparative Table 🆚The main difference between sensorineural and conductive hearing loss lies in the cause and the treatment options. Here are the key differences:
Sensorineural Hearing Loss (SNHL):
- Caused by damage to the inner ear or auditory nerve, such as damage to the tiny hair cells in the ear that vibrate in response to sound.
- Common causes include aging, exposure to loud noises, viral infections, head injury, genetics, and certain medications.
- Treatment options may include hearing aids, cochlear implants, and compensatory strategies.
Conductive Hearing Loss:
- Occurs when there is an obstruction or damage in the outer or middle ear that prevents sound from reaching the inner ear.
- Common causes include wax impaction, foreign objects, perforated eardrums, and infections.
- Treatment options may include medication, surgery, or the removal of obstruction, depending on the cause.
A mixed hearing loss is a combination of both sensorineural and conductive hearing loss. The appropriate treatment for each type of hearing loss depends on the specific cause and individual circumstances. Early diagnosis is crucial for the best possible treatment outcomes.
Comparative Table: Sensorineural vs Conductive Hearing Loss
Feature | Sensorineural Hearing Loss (SNHL) | Conductive Hearing Loss (CHL) |
---|---|---|
Cause | Damage to inner ear or auditory nerve | Blockage in outer or middle ear |
Treatment | Hearing aids, cochlear implants | Removing blockage, medication |
Permanence | Permanent in most cases | May be temporary or chronic |
Symptoms | Difficulty understanding speech, especially in noisy environments | Difficulty hearing faint sounds or understanding speech in noisy environments |
Type | Most common type of hearing loss | Less common type of hearing loss |
Location | Inner ear, cochlea, or neural pathway | External ear, middle ear, or both |
Sensorineural hearing loss (SNHL) is the result of damage to the inner ear or auditory nerve, while conductive hearing loss (CHL) occurs when sounds are blocked from reaching the inner ear due to a problem or blockage in the outer and/or middle ear. The main differences between the two types of hearing loss lie in their causes, treatment options, and permanence.
