Abstract:
Objective To study the positions,features and sectional anatomy of the palatovaginal canal and vomerovaginal canal,comparing with CT and MRI findings. Methods The palatovaginal canals in 104 sides and vomerovaginal canals in 60 sides of dry skulls were observed.Three adult cephalic specimens were sliced into celloidin contiguous sections on coronal plane(0.5 mm in thickness) and the results were correlated with the CT studies of 11 patients and MR imaging of a cephalic specimen. Results In dry skulls,the palatovaginal canal displayed as complete canal in 79.8% of the cases,while appeared as groof in 15.4%.There was neither significant canal nor groof in 4.8%.The vomerovaginal canal demonstrated as complete canal in 36.7% of the speciments,while appeared as groof in 33.3%.This canal was communicated with the lateral palatovaginal canal in 15% and it was not detected in 15%.Four typical slices of the celloidin and 3 plane of CT and 3 plane of MRI were selected and the key structures were described.Conclusion The palatovaginal canal and vomerovaginal canal can be well depicted on coronal plane.
