Ossiculoplasty is the reconstruction of the ossicular chain of the middle ear.
Anatomy
ossicles (very small bones) of the ear include from outside to inside:
- The hammer.
- The anvil.
- The stirrup.
These ossicles, articulated between them, are located in themiddle ear and transmit through the tympanic cavity, vibrations at the oval window.
After analysis by the brain, these vibrations are the origin of the sound perceived by an individual. The ear is an organ composed of three parts:
- L'inner ear.
- L'middle ear.
- L'outer ear.

Technical
L'ossiculoplasty aims to repair a lesion in the chain of ossicles, which follows a otitis most often, and more rarely, occurs after a fracture or even a dislocation of the ossicles.
L'ossiculectomy is the surgical procedure to remove the ossicles of the middle ear.
