Small cavity mastoidectomy.
Disappointment with the long-term results of closed operations for ears with extensive cholesteatoma has led to a renewed preference for open techniques. Although the technical advantages provided by magnification and hypotensive anaesthesia have reduced the numbers of unstable post-operative open mastoidectomy cavities, when large, they are still frequently troublesome. Frequently, surgical cavities have been much larger than necessary because of adherence to a traditional approach to the pathologic lesion from its posterior aspect, and the inevitable removal of much normal bone. It is proposed herein that if, instead, bone removal were commenced from the area proximate to the origin of the disease and extended only as far as necessary in order to achieve adequate and effective exteriorization of the disease, fewer large cavities would result and the proportion of stable post-operative ears would be increased. To test this, 100 patients have been treated by atticoantrotomy in which bone lateral to the cholesteatoma sac was removed from anterior to posterior. The 5-year status of the first 43 patients thus treated supports the view that atticoantrotomy provides a logical, safe and successful means of treating extensive cholesteatoma.
