SYN: reduced incus size
SYN: decreased incus size

incus hypoplasia
DEF: underdevelopment or reduced size, usually due to reduced cell number, of the anvil-shaped, central bone of the three auditory ossicles which articulates with the head of the malleus anteromedially and the stapes inferomedially
