What is incus in ear?
The incus, also known as the “anvil,” is the middle of three small bones in the middle ear. The incus transmits vibrations from the malleus to the stapes. The vibrations then move to the inner ear. Conditions that affect the incus often affect the other ossicle bones.
What is incus anatomy?
The incus (plural: incudes) is the middle of the three ossicles articulating with the head of the malleus anteromedially, forming the incudomalleolar joint, and the stapes inferomedially, forming the incudostapedial joint.
What is long process of incus?
The long process of the incus is connected to the head of the stapes by the lenticular process. This region, which we refer to as the “distal incus”, is frequently affected by middle-ear disease. For example, the distal incus is often a site of bone erosion in chronic otitis media.
What is the Lentiform nodule?
a long crus (or process) down to the lentiform process (a.k.a. lentiform nodule) which articulates with the head of the stapes. a short crus (or process) to which the posterior ligament of the incus is attached.

Why is anvil called incus?
The anvil-shaped small bone is one of three ossicles in the middle ear. The incus receives vibrations from the malleus, to which it is connected laterally, and transmits these to the stapes medially. The incus is so-called because of its resemblance to an anvil (Latin: Incus).

What are the complications of incus interposition grafting?
Complications of incus interposition grafting that can be identified at CT and are amenable to surgery include prosthetic subluxation, incudal necrosis, reparative granuloma formation, and recurrent cholesteatoma. Of these complications, subluxation is the most difficult to identify at CT.
