Spongy bone growing between the auditory ossicles is called otosclerosis. This is one of the causes of Conductive Deafness or Hearing Loss where the ossicles are not able to "conduct" the sound vibrations from the eardrum to the oval window. The spongy bone "dampens" the vibrations instead of amplifying them.
ossicles
Fusion or fixation of the auditory ossicles is primarily a congenital problem (you're born with it). However, it can be caused by other factors such as:old-age calicification of the ossiclesscar tissue from repeated infections or traumaformation of bony overgrowthsformation of spongy bone in the labyrinth
spongy and compact
The compact bone surrounds the spongy bone and provides structure for the body.
No. Flat bones consist of spongy bone sandwiched between compact bone.
Red marrow is found within the trabeculae of spongy bone.

The compact bone has a continuous matrix with no gaps while the spongy bone has numerous branching bony plates. The irregular connecting spaces between the plates help reduce the bone's weight in the spongy bone.

Spongy bone can appear yellow because it has some fat in it, and it is possible to see small holes in spongy bone. Also, spongy bone is not long (like the wrist). Compact bone is usually long (like a femur) and white.
Spongy bones are not literally spongy. These bones are just extremely porous giving the appearance of looking like spongy material.
