Special Senses -The Eye and the Ear

Below is a case study presentation of a patient with a condition covered by one of the chapters you have been studying this week. Read the case study and answer the questions below. Some questions will ask for information not included within this chapter. Use your course text, a medical dictionary, the Internet, or any other reference material you choose to answer these questions.

This 35-year-old male musician was seen in the EENT clinic complaining of a progressive hearing loss over the past 15 years. He is now unable to hear what is being said if there is any environmental noise present. He states that he has played with a group of musicians using acoustic instruments and no earplugs for the past 20 years. External ear structures appear normal bilaterally with otoscopy.

Tympanometry is normal bilaterally. Audiometric testing reveals diminished hearing bilaterally. Rinne and Weber tuning-fork tests indicate that the patient has a moderate amount of sensorineural hearing loss, but rule out conductive hearing loss.

Diagnosis is moderate bilateral sensorineural hearing loss as a result of prolonged exposure to loud noise. Patient is referred for evaluation for an amplification device.

  1. Which type of hearing loss does this patient appear to have? Look this condition up in a reference source and include a short description of it.
  2. Explain how the other type of hearing loss (the type ruled out by the Rinne and Weber tuningfork tests) is different from what this patient has?
  3. What diagnostic tests did the physician perform? Describe them in your own words.
  4. Describe different amplification devices.
  5. How do you think this patient could have avoided this hearing loss?
