Abstract:
BACKGROUND AND OBJECTIVES: The aim of our study is to analyze the characteristics and outcomes of revision surgery for chronic otitis media. SUBJECTS AND METHOD: Retrospective review of the revision tympanomastoidectomy from January 1, 1997 to December 31, 2004 (N=208) were performed. The control group who underwent primary canal wall down mastoidectomy (CWDM, N=51) was compared with the case group who underwent revision CWDM. RESULTS: As a cause of revision ear surgery, recurrent cholesteatoma comprised 38% of the cases, and granulation tissue in the unexenterated air cells were found to be 62%. Mastoid tip and perisinal air cells were most frequent sites of unexenterated air cells. CWDM was performed in 96.6% of the patients. Disease control was achieved in 88.5% of the patients. The 70.1% of revision CWDM with ossiculoplasty achieved a residual air-bone gap (ABG) of < or = 30 dB. Complications after revision surgery were wound infection (3.8%) and temporary facial nerve palsy (1.9%). In the control group, disease control rate, postoperative ABG < or = 30 dB, wound infection and facial nerve palsy were 90.2%, 90.5%, 5.9% and 0% of patients, respectively. CONCLUSION: Disease control rates and complications after revision surgery are similar to primary cases. However, hearing results were worse and wound healing time was longer than primary ones.
