Objective  To evaluate the diagnosis value of temporal Done high-resolution computed tornography (HRCT) in cholesteatoma.
Methods  There were 30 causes that had received the mastoid surgery because of cholesteatoma. Each patient’s mastoid plain films (Schuller’s and Mayer’s ) and HRCT had been taken and compared with each other and surgical findings and evaluated with health economic evaluation methods.
Results  The sensitivity rate in diagnosing cholesteatoma with HRCF was much higher than that with mastoid film (P lt;0.005). The more important benefit with HRCT was that it can afford the detail information in ear such as the ossicular chain, facial nerve canal, tympanic sinus, etc. which were basis for otologist in surgery to remove the focus thoroughly and reconstruct the middle ear function at the same time. In the view of health economic evaluation, HRCT is also much better than mastoid X-ray film.
Conclusion  HRCT should replace masloid Schuller’s and Mayer’s film in diagnosis cholesteatoma and HRCT should use as ordinary examination in chronic otitis media.
