Abstract:
Objective To discuss the microanatomy features of jugular foramen region in transpetrosal-presigmoidal minimally invasive approach based on virtual reality image models.Methods CT and MRI scans were performed to fifteen adult cadaver heads,and then,imaging data were inputted into Vitrea virtual reality system to establish three-dimensional anatomy models of jugular foramen region.Different minimally invasive transpetrosal-presigrnoidal approaches exposing superior edge of internal acoustic meatus (route A),anterior edge of jugular foramen (route B),and posterior edge of jugular foramen (route C) were simulated by selecting osseous landmark points.Anatomic exposures in surgical trajectory following alternation of minimally invasive approach were observed,measured and compared.Results Spacial sequence of nerves and vessels in the route simulating transpetrosal-presigmoidal approach for exposure of jugular foramen region was displayed clearly;route A had the highest location and route C was the lowest.Volumes of route and petrosal osseous structure involved in route A was the largest,and then,volumes of route and osseous structure involved in route B was larger than those in route C,with significant differences (P<0.05).Volumes of involved venous sinus were as follow:route B>route A>route C,with significant differences (P<0.05).Volumes of facial-acoustic nerve complex and anterior inferior cerebellar artery involved in route A were (53.32± 5.54) mm3 and (30.55±3.51) mm3,respectively.Volumes of lower cranial nerves involved in route B were (84.59±9.23) mm3.Conclusion There are different impacts on the osseous structures and venous sinus for the minimally invasive routes of transpetrosal-presigmoidal approach exposing different targets,of which combinations are helpful to utilize respective advantages.
