Learning Objectives: To present how to do glass ionomer in ossicular reconstruction.
Objective: Eustachian tube dysfunction may deteriorate physiology of middle ear pressure and ventilation that result in ear drum retraction. Cholesteatoma can develop from retraction pocket that may result in ossicular erosion. On the other hand, Ossicular erosion may result from prolonged contact between tympanic membrane and ossicular chain without active infection and cholesteatoma.
Long process of the incus, lenticular process and/or stapes superstructure can be effected and result in complete or partial ossicular discontinuity. In lenticular process erosion, bone cement can be used for reconstruction. Incus interposition, malleus-stapes bone sement or ossicular prosthesis are the reconstruction options in case of incus long process erosion.
Materials and Methods: Thirty patients whose underwent ossicular chain reconstruction with bone cement included in the study. Glass ionomer was used for reconstruction by otomicroscope or endoscope. We compared preoperaive and postoperative audiogram findings.
Results: We found better result of ossicular reconstruction with glass ionomer in lenticular process erosion. Malleus-stapes bone cement application or incus interposition can be performed in case of incus long process erosion.
Conclusion: Glass ionomer can be safely used for ossicular reconstruction in patient with adesive otitis media that cause ssicular discontinuity.
