Summary |
Objectives |
To assess prevalence and location of residual cholesteatoma following closed “canal wall up” tympanoplasty (CWUT). The evolution of follow-up strategy is discussed.
Patients and methods |
A retrospective study was run in adults operated on by CWUT for middle-ear cholesteatoma and who had undergone second look surgery and/or postoperative radiology (CT-scan, diffusion-weighted MRI).
Results |
One hundred and nine patients (113 ears) underwent the procedure. Mean follow-up was 48months (range, 24–96months). Twenty-nine residual cholesteatomas were found (25%), including 11 located in the anterior attic (38%). Follow-up included 77 second look operations (70%), and 71 radiological examinations (62 CT-scans and nine diffusion-weighted MRIs). Second look surgery was without benefit for the patient (no residual, no ossiculoplasty) in one third of cases.
Conclusion |
Residual cholesteatoma in the anterior attic is a problem in CWUT. When postoperative auditory results are good, second look surgery should not be systematic but guided by high quality imaging.
