Mastoid obliteration with bone dust mixed with concentrated growth factor.

BACKGROUND

Mastoid obliteration is a useful surgical step in the treatment of chronic ear operation. The technique of mastoid obliteration involves filling the cavity with self-tissue and/or osseocartilaginous graft material, following removing the mastoid air cell.

OBJECTIVE

The aim of this study is to show the advantages of mastoid obliteration using a mixture of CGF and bone dust.

MATERIAL AND METHOD

Bone dust was collected with an apparatus from the healthy mastoid cortex. Collected bone dust was mixed with CGF to form a gel. Then, mastoid cavity and epitympanum obliteration were performed.

RESULTS

Fifteen patients who underwent canal wall down mastoidectomy for cholesteatoma were included in the study. In all patients, the targeted external ear canal and hearing results were obtained after obliteration.

CONCLUSION

It is an effective surgical technique for creating a natural external ear path after mastoidectomy applied for mastoid obliteration, chronic ear infections and cholesteatoma treatment with CGF. Mastoid obliteration using bone dust mixed with CFG is an effective surgical technique to create a natural and healthy external ear canal.
