Reconstruction of bony canal with autogenous bone graft

The advantages of preservation of the bony posterior wall of the external auditory canal during surgery for chronic infection have been stressed by many authors. The superior canal wall is often partially destroyed by cholesteatoma, or must necessarily be removed, to insure adequate removal of attic pathology. Numerous techniques and grafting material will be reviewed. Our technique of using autogenous bone, cut with a thin chisel which curls to the shape of the ear canal, will be presented and illustrated.
