Abstract

Background

30° and 45° endoscopes are commonly used, but there are few reports about the use of 70° endoscopes for ear surgery.

Methods

The use of 70° endoscopes made it possible to resect cholesteatomas without removing extensive regions of the external ear canal, which facilitated reconstruction, as the areas that needed to be reconstructed were smaller.

Conclusion

None of the 34 patients who underwent this procedure for pars flaccida cholesteatoma suffered recurrence. Therefore, we consider that the procedure is useful. A further study of the postoperative outcomes of this procedure should be conducted.
