Assessment by audiotympanometric testing: three case reports

Area of Science:

• Audiology
• Otolaryngology

Background:

• Tympanometry is a valuable tool for assessing middle-ear function.
• Its utility is particularly noted in cases with multiple co-existing ear pathologies.

Observation:

• Three distinct cases highlight tympanometry's diagnostic capabilities.
• These cases involved complex audiological presentations requiring advanced assessment.

Findings:

• Static conductance measures identified ossicular chain stiffness in a patient with sensorineural loss.
• Tympanometry and reflex testing diagnosed and monitored serous otitis media in an infant.
• Low conductance and high impedance indicated ossicular chain immobility in a patient with basal skull fracture.

Implications:

• Tympanometry provides rapid, accurate, and objective measurements for complex middle-ear diagnoses.
• It enhances diagnostic precision beyond conventional otological and audiological evaluations.
• This technique is crucial for effective management of intricate ear conditions.
