Chronic inflammatory ear disease and cholesteatoma: creation of auxiliary attic aeration pathways by microdissection.

Abstract

When the ossicular chain is discontinuous, tensor fold resection can be made under direct vision. With an intact chain, cutting of the neck of the malleus used in tympanic glomus tumors causes no hearing changes, allows complete fold excision, and is adaptable to chronic ear surgery. The frontolateral attic route for removal of tensor fold, together with the lateral incudomalleal fold, can be used in the canal wall up surgery to improve attic aeration.
