Abstract

BACKGROUND AND OBJECTIVES
There is no general consensus on the risk factors affecting the recurrence or residual disease (recidivism) after surgery of congenital cholesteatoma of the middle ear. In this study, we analyzed clinical characteristics of recidivistic cases after the surgery and compared those of non-recurrent cases to investigate the risk factors regarding the post-operative recidivism of the disease.
SUBJECTS AND METHOD
Data were collected from retrospective chart reviews and computerized database of patients who have underwent surgeries at Kangdong and Hallym University Sacred Heart Hospital during the last 24 years. All surgeries, consisting of 95 primary cases and 24 revision cases, were performed by the same surgeon.
RESULTS
Recurrence was detected in 24 cases of the 95 patients (including 4 cases, of which primary surgeries were done at other hospitals). Among the risk factors affecting post-operative recidivism such as sex, age, symptom, disease duration, type of cholesteatoma, mastoid pneumatization, ossicle status, and stage of disease, factors of longer symptom duration, poor mastoid pneumatization, older age, poor mastoid pneumatization, advanced or recurrent cholesteatoma were significantly related to the recidivism of disease.
CONCLUSION
Longer symptom duration, poor mastoid pneumatization, and advanced or recurrent cholesteatoma were revealed as high risk factors for post-operative recidivism in this study.
