Otologists who prefer intact canal wall surgery for removal of cholesteatoma recognize a 12–25% return rate. Revisions often indicated to correct hearing loss are frequently negative for recurrent cholesteatoma. To determine the reliability of a noninvasive method of diagnosing recurrent disease and possible complications, 40 patients previously operated on for cholesteatoma using the intact canal wall technique were scanned with a General Electric 8800 scanner. Second procedures were performed on 24 patients and findings compared with preoperative film interpretations. Scans correctly predicted no significant masses in 6 patients and cholesteatoma recurrence in 11; the remaining 6 with diffuse soft tissue changes were incorrectly diagnosed. Focal areas of bone erosion were detectable in 3 cases, indicating active or potential complications. Scans were reliable in detecting cholesteatoma depending upon the pathology.
