What is the primary purpose of integrating pure tone audiometry and tympanometry results in audiological assessment?
What is the primary purpose of integrating pure tone audiometry and tympanometry results in audiological assessment?
To determine the type and degree of hearing loss, as well as the site of lesion.
A patient presents with a flat audiogram and abnormal tympanometry results. What is the most likely type of hearing loss in this patient?
A patient presents with a flat audiogram and abnormal tympanometry results. What is the most likely type of hearing loss in this patient?
Conductive hearing loss, likely due to middle ear dysfunction.
What is the significance of a normal tympanogram in a patient with sensorineural hearing loss?
What is the significance of a normal tympanogram in a patient with sensorineural hearing loss?
It suggests that the hearing loss is not related to middle ear pathology.
A patient has a purely sensorineural hearing loss in one ear and a mixed hearing loss in the other ear. How would you interpret the tympanometry results in each ear?

Study Notes
Audiological Assessment Integration
- Combining pure tone audiometry and tympanometry provides a comprehensive view of hearing status and middle ear function.
- This integration helps in distinguishing between different types of hearing loss and their underlying causes.
Hearing Loss Type with Flat Audiogram
- A flat audiogram typically indicates conductive hearing loss.
- Abnormal tympanometry results further suggest issues in the middle ear, reinforcing the likelihood of conductive loss.
Normal Tympanogram and Sensorineural Hearing Loss
- A normal tympanogram in a patient with sensorineural hearing loss suggests intact middle ear function.
- This indicates that the hearing loss originates from the inner ear or auditory nerve, not from middle ear problems.
Tympanometry Results Interpretation
- For a patient with sensorineural hearing loss in one ear, tympanometry results should show normal middle ear function in that ear.
- For the ear with mixed hearing loss, tympanometry may show abnormal results due to associated middle ear issues, highlighting the difference in pathology between the two ears.
Importance of Type of Hearing Loss in Interpretation
- Identifying whether hearing loss is conductive, sensorineural, or mixed is crucial for accurate diagnosis and treatment planning.
- Each type of hearing loss has distinct implications for management and intervention strategies, affecting patient outcomes.
