5. Conclusion
The study quantifies the shape and morphology of the IAC from landmark measurements on CT images. Inter-person variations observed imply that the dimensions and shape of the IAC cannot be generalised. The information from this study could assist researchers to reconstruct 3D computational cochlear models that include the IAC. As the shapes of the IAC have been linked to some malformations and diseases, it can be used as a diagnostic tool for otorhinologists.
