Comparison of microscopic and transcanal endoscopic ear surgery for Naim stage I-III external auditory canal cholesteatoma.

No postoperative cholesteatoma recurrence or EAC stenosis/atresia occurred in transcanal endoscopic ear surgery.

Conversely, microscopic ear surgery complications included isolated recurrence ( n = 2, 4.4%), isolated EAC stenosis/atresia ( n = 1, 2.2%), concurrent recurrence and stenosis ( n = 3, 6.7%), and transient facial paralysis ( n = 1, 2.2%).
