The difference between Conductive and Sensorineural hearing loss

Sample Solution

     

1. Conductive vs. Sensorineural Hearing Loss

Conductive hearing loss occurs when sound waves are blocked or reduced in the outer or middle ear. This type of hearing loss often improves with treatment.  

• Causes: Earwax buildup, fluid in the middle ear (from infection), perforations in the eardrum, or abnormalities in the bones of the middle ear.
• Symptoms: Muffled hearing, difficulty understanding speech, especially in noisy environments

      Sensorineural hearing loss happens when there's damage to the inner ear or the auditory nerve. This type of hearing loss is often permanent.     Causes: Aging, noise exposure, head trauma, certain medications, genetic disorders, and underlying medical conditions.   Symptoms: Difficulty understanding speech, especially high-pitched sounds, tinnitus (ringing in the ears), and problems hearing in noisy environments.

Key difference: The location of the problem. Conductive hearing loss is in the outer or middle ear, while sensorineural hearing loss is in the inner ear.

To identify potential risk factors for hearing loss, I would ask patients the following questions:

Personal History

• Have you experienced any hearing loss or difficulty hearing?
• Do you experience tinnitus (ringing in the ears)?
• Have you had any ear infections, injuries, or surgeries?
• Do you have a family history of hearing loss?

Occupational History

• Are you exposed to loud noise at work?
• Do you use hearing protection at work?
• What type of work do you do?

Lifestyle Factors

• Do you listen to loud music or use headphones frequently?
• Do you smoke?
• Do you consume excessive alcohol?
• Do you engage in activities with a high risk of head injury (e.g., contact sports)?

Medical History

• Do you have any chronic medical conditions (e.g., diabetes, hypertension, autoimmune diseases)?
• Are you taking any medications?
• Have you undergone any recent illnesses or infections?

By asking these questions, I can identify potential risk factors for hearing loss and develop an appropriate plan for prevention, early detection, and management.
