Summary:Procedures for tympanoplasty in Japan had been varied from the open method (canal wall down technique) to the closed method (canal wall up technique), and further to the staged operation and the obliterative method (mastoid obliteration). The reasons for the former change had been attributable to the cavity problem after the open method, and the latter to the high recurrence rate of cholesteatoma after closed method. Additionally, these procedures required mastoidectomy, which means destruction of mastoid cells. Recently, severity of inflammatory process of chronic otitis media has been decreasing, and normal mastoid cell mucosa has been recognized to perf orme gas-exchange of the middle ear, as a result, the number of operation for chronic otitis media in which mastoid cells are preserved is increasing gradually.
