Abstract
Objective: To provide anatomical basis for operation of internal auditory meatus(IAM). Methods: The blue line of superior semicircular canal went through the mill and correlative structures were measured on 24 cases of wet cranial bone specimens(48 sides) .Results: The projective distance from arch apex to posterior wall and anterior wall of internal auditory meaus(IAM)were 6.18 ± 0.25(5.11-7.23)mm and 13.23 ± 0.47(11.2 - 14.2l)mm respectively. The straight distance from arch apex to posterior wall and anterior wall of IAM were 7.03 ± 0.26(6.01 - 7.85)mm and 14.44± 0.76(12.03 ± 15.77)mm respectively. Conclusion: These above data are very helpful for the location of IAM in the operation of middle cranial fossa approach.
