3D micro-CT images of ossicles destroyed by middle ear cholesteatoma.

Objectives: To reconstruct the 3D structures of normal ossicles and ossicles destroyed by different cholesteatomas, and to compare the volume fractions of the two types of ossicles.

Materials And Method: Thirteen pathological ossicles from four kinds of middle ear cholesteatoma obtained during surgery were used. Normal ossicles harvested from cadaveric temporal bone specimens were used as controls.
