Background and Objectives Temporal bone is a complicated structure anatomically. Highresolution computed tomography (HRCT) provides a good method for examination of the middle ear, inner ear anatomy and pathologic changes in the temporal bones. The purpose of this study is to evaluate the relations of facial nerve and other structures in temporal bone and factors influencing access to posterior tympanotomy according to the age, sex and degree of temporal bone pneumatizaton. Subjects and Method A total of 133 ears of temporal bone computer tomograph (TBCT) were analyzed. We measured the distances and angle between important surgical landmarks, and compared the data according to the age, sex and mastoid pneumatization. Results We presented the angle between the posterior wall of external auditory canal and the facial nerve with the index for facial nerve preservation in posterior tympanotomy. This angle is 10.05° other indices are not related statistically. Conclusion This results may enable preoperative assessment and provide background knowledge to prevent facial nerve injury when performing a posterior tympanotomy.
