Abstract

Objective

This study sought to compare disease recidivism rates between canal wall up mastoidectomy and a canal wall down with obliteration technique.

Methods

Patients undergoing primary cholesteatoma surgery at our institution over a five-year period (2013–2017) using the aforementioned techniques were eligible for inclusion in the study. Rates of discharge and disease recidivism were analysed using chi-square statistics.

Results

A total of 104 ears (98 patients) were included. The mean follow-up period was 30 months (range, 12–52 months). A canal wall down with mastoid obliteration technique was performed in 55 cases and a canal wall up approach was performed in 49 cases. Disease recidivism rates were 7.3 per cent and 16.3 per cent in the canal wall down with mastoid obliteration and canal wall up groups respectively (p = 0.02), whilst discharge rates were similar (7.3 per cent and 10.2 per cent respectively).

Conclusion

Our direct comparative data suggest that canal wall down mastoidectomy with obliteration is superior to a canal wall up technique in primary cholesteatoma surgery, providing a lower recidivism rate combined with a low post-operative ear discharge rate.
