Ossiculoplasty using a hemi-incus interposition.
A damaged incus is one of the common reconstruction problems encountered by the otologic surgeon. Eighty-five hemi-incus interposition reconstructive procedures performed between 1976 and 1982 were reviewed. Reconstruction consisted of an autogenous or homologous incus bone graft interposed between the tympanic membrane and the mobile stapes superstructure. Air bone gap closure to within 20 dB was obtained in 77% of cases. Reconstruction using bone graft is better tolerated by the middle ear and the extrusion rate less than that of the biocompatible implants.
