ABSTRACT
Background and Objectives@#To investigate surgical outcomes of revision operation for recurrent cholesteatoma.Subjects and Method From 1989 to 2018, 5245 cases of middle ear surgeries were performed at Kangdong and Hallym University Sacred Heart Hospital. A total of 138 clinical records of the subjects who underwent revision cholesteatoma surgery, and whose follow-up durations were more than 3 months, were reviewed. Hearing outcomes were analyzed in accordance with the 2005 Korean otology society guideline. Postoperative perforation was defined to be present if perforation exists after three months of surgery. Postoperative infection or recurrence was defined if patients were treated with intravenous antibiotics or underwent reoperation. @*Results@#Among 138 cases, surgical approaches used were canal wall up mastoidectomy in 38 (28%), canal wall down mastoidectomy in 89 (64%), and exploratory tympanotomy in 11 (8%). Air conduction and air bone gap showed statistically significant differences before and after the surgery. The number of patients who met at least 1 criteria was 70, accounting for 51%. Patients were classified into four groups according to the Postoperative ABG grade, where 43% of patients were included in “Excellent” or “Good” results group. When the results were compared according to the surgical method, canal wall up group showed significantly higher hearing success rate compared to CWDM group. Patients without postoperative perforation, infection or recurrence were considered successful and there were 122 such cases, accounting for 88%. @*Conclusion@#CWDM more frequently underwent revision than CWUM and ET, and showed worse hearing results than other groups. These analyses can be used for preoperative counseling.
