A Biomechanical Model of the Inner Ear: Numerical Simulation of the Caloric Test

Figure 3

Time histories of the temperature (a), endolymph velocity (b), and cupula displacement (c) for a hot supine caloric test with . The tested point in the HC duct is P1, in the HC ampulla is P2, on the HC cupula is P3, in the utricle is P4, in the AC duct is P5, on the AC cupula is P6, in the PC duct is P7, and on the PC cupula is P8. P1~P8 are defined in Figure 1(b). The velocity is positive for an ampullopetal flow in the HC duct and in the HC ampulla, for an ampullopetal flow in the AC and PC ducts, and for an utriculofugal flow in the utricle. Meanwhile, the deflection to the utricle side is positive for the HC cupula and to the canal side for the AC and PC cupulae.
