AB  - BACKGROUND: In recent years, the otoendoscopic surgery for epitympanic
      cholesteatoma has achieved great development, but it still has some
      disadvantages. OBJECTIVE: This work aims to improve otoendoscopic surgery for
      epitympanic cholesteatoma invading the mastoid to retain the normal structure of 
      the middle ear as much as possible. METHODS: We classified the patients according
      to the lesion scope and applied different strategies of using the combination of 
      otoendoscope and microscope. The surgery was improved and the recurrence and
      residual of middle ear cholesteatoma after operation were observed preliminarily.
      RESULTS: Forty-six patients with middle ear cholesteatoma accepted surgical
      treatment, including 10 cases of independent otoendoscopic surgery, 29 cases of
      otoendoscope-microscope combined surgery, and seven cases of microscopic surgery 
      assisted with an otoendoscope. All cases were treated with canal-up cholesteatoma
      surgery. The postoperative recurrent rate was 4/46. CONCLUSION: We improved
      existing otoendoscopic surgery to reduce or avoid bony defects of the acoustic
      meatus, and then decreased the proportion of canal-down surgery.
