Tympanoplasty is a surgical procedure that tries to recreate a functional conduction system of the ear. It is classified among the so-called reconstructive operations, which are operations whose goal is to restore the function of the middle ear. As part of remedial surgical procedures, it is often necessary to remove the bone affected by inflammation (hammer, anvil). The defect created in this way must then be solved surgically – tympanoplasty.
In order to be able to indicate tympanoplastiku, tympanoplasty, it is necessary that:
- the inflammation was completely eradicated;
- bone conduction was preserved;
- the Eustachian tube was functional;
- the middle ear mucosa was of good quality.
- Classification of tymponoplasty
- Tympanoplasty I: the suprastructures of the stapes and manubrium of the malleus are preserved, the rest of the middle ear transmission system is replaced using a partial ossicular replacement prosthesis (PORP).
- Tympanoplasty II: all middle ear ossicles are missing, they are replaced by TORP prosthesis - total ossicular replacement prosthesis.
Both autologous (cartilage, bone) and synthetic (plastic, metals, etc.) materials are used for the production of prostheses.
