Cholesteatoma surgery today.
Four present-day surgical techniques are reviewed to assess their respective merits in surgery for cholesteatoma. The oldest method with an open cavity in ears with mastoid extension of cholesteatoma if combined with partial obliteration is still suitable for less experienced surgeons. Transcanal atticotympanotomy is suitable for limited epitympanic and tympanic cholesteatomas as long as it provides a direct view of the operative field. In similar ears, canal wall up surgery is employed if, additionally, mastoidectomy is needed because of chronic inflammation. Canal wall down surgery with full cavity obliteration with a musculoperiosteal flap, bone chips and bone pate should be the method of choice for all cholesteatomas extending beyond the facial nerve canal. The canal skin is kept as an intact tube and provides quick healing. Open cavities should be revised using similar obliteration techniques but, because of the lack of an intact canal skin tube, making use of a large modified Körner skin flap.
