Abstract:
A change in body posture from sitting to reclined is known to cause an increase in intracochlear fluid pressure, if the cochlear aqueduct is patent. Previous studies have shown this increase to have an effect on middle ear dynamics. The aim of this study was to investigate whether such increases in cochlear pressure may affect the stiffness of, and hence the resonance frequency of the middle ear. No consistent group or individual differences were shown between the two postural conditions.
