Figure 3. Normal anatomy of the incus. Three-dimensional VR CT image (inferolateral view) shows the body of the incus (BI), which demonstrates a facet (F) on its anterior surface that articulates with the head of the malleus. The short process (SP) is directed posterolaterally, and the long process (LP) is directed inferiorly. The tip of the long process bends medially to end in a rounded projection, the lenticular process (LnP), which articulates with the head of the stapes.
