Lesion of ossicular chain is a common ear diseaseimpairing the sense of hearing.A comprehensive numeri-cal model of human ear can provide better understandingof sound transmission.In this study,we propose athree-dimensional finite element model of human ear thatincorporates the canal,tympanic membrane,ossicular bones,middle ear suspensory ligaments/muscles,middle ear cavityand inner ear fluid.Numerical analysis is conducted andemployed to predict the effects of middle ear cavity,mal-leus handle defect,hypoplasia of the long process of incus,and stapedial crus defect on sound transmission.The presentfinite element model is shown to be reasonable in predictingthe ossicular mechanics of human ear.
