Precise reconstruction of auditory canal defect in external auditory canal cholestestoma with bonewax template

Abstract EN

Precise reconstruction of external auditory canal (EAC) defect is important for the prevention of retraction pocket and recurrent cholesteatoma.

This report describes a new technique for the reconstruction of EAC defect by using bonewax template and the cortical bone.

Canal defect reconstruction was performed successfully after the removal of EAC cholesteatoma.

There has been no recurrence, and the outcome was excellent.

This method avoids a sharp edge in EAC, which deters good epithelialization and promotes granulation tissue and enables the avoidance of subsequent retraction and formation of recurrent cholesteatoma.

We recommend the use of bonewax template for the reconstruction of canal defects as a simple and precise method.
