Transcanal endoscopic ear surgery is a minimally invasive procedure that allows a clear visualization of the middle ear. Recently, indications for endoscopic surgery have been expanding. We performed combined underwater endoscopic and microscopic surgery for external auditory canal cholesteatoma, the computer tomography of which indicates the possibility of cholesteatoma not only in the canal wall but also in the mastoid. The 30° endoscope and underwater technique makes the surgical view clear, and we could remove the cholesteatoma without canalplasty. To the best of our knowledge, no case of external auditory canal cholesteatoma treated with underwater endoscopic and microscopic surgery has been previously reported. This case indicates that the procedure could be a good indication for external auditory canal cholesteatoma.
