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.
