Abstract

Objective

This study aimed to analyse the differences between underwater continuous drilling and traditional intermittent drilling for attic cholesteatoma.

Methods

The clinical data of 61 patients with attic cholesteatoma who underwent an endoscopic approach procedure were analysed. Forty patients underwent underwater continuous drilling (group A), and 21 patients underwent traditional intermittent drilling (group B).

Results

The operation time was 64.61 ± 12.90 minutes in group A and 79.60 ± 16.81 minutes in group B (p < 0.05). The anaesthesia time was 102.69 ± 17.93 minutes in group A and 119.82 ± 19.28 minutes in group B (p < 0.05). The dry ear time, the hearing improvement rate and the post-operative complications were no different in the two groups.

Conclusion

Group A and group B had no differences in surgical outcome or hearing recovery. However, treatment in the former group resulted in a significantly shortened operation and anaesthesia time.
