Abstract：Objective: To discuss the guidance of temporal bone HRCT in the treatment of cholesteatoma of middle ear. Methods: We compared the temporal bone HRCT imaging of 60 patients with cholesteatoma of middle ear with the actual situation of operation. Results: The temporal bone HRCT clearly showed middle ear bone destruction and the structure of ossicular chain, so that we could predict surgical route of mastoidectomy very accurately, as well as accurately predict surgical procedures of mastoidectomy and tympanoplasty type. Conclusions: The temporal bone HRCT is significant to select surgical procedures and route of mastoidectomy and the type of tympanoplasty.

Key words: cholesteatoma of middle ear, temporal bone HRCT, MPR, mastoidectomy, tympanoplasty
