Objectives:
To analyze the characteristics and outcomes of revision surgery for chronic otitis media (COM) with or without cholesteatoma, and to compare with those of primary surgery.
Methods:
A retrospective chart review was performed on 208 patients who underwent revision surgery for COM over an 8-year period (1997-2004) and 51 patients who underwent a primary canal wall down mastoidectomy (CWDM), and were followed for more than 12 months.
Results:
Recurrent or residual cholesteatoma was found in 49.5% of cases. The mastoid tip and perisinal air cells were the most frequent sites of residual air cells. As a result of revision surgery, a dry and safe ear was achieved in 88.5% of patients. A residual air-bone gap (ABG) of
Conclusion:
The characteristics and surgical outcome of recurrent COM must be fully understood for complete control of the disease.
