The aim of this study was to evaluate the feasibility of using fresh cow brain as a training model for microsurgical dissection of Sylvian fissure. Microneurosurgical intervention to the brain includes many surgical activities performed by using metallic instruments to the vascular and/or parenchymal structure of the nervous system.
Experimental microneurosurgical activities in this study were performed under the operating microscope. Bilateral sylvian cisterns of the fresh cadaveric cow brain were used as an interested area for this experiment. The dissection and separation was continued to the floor of the cistern was reached and the middle cerebral artery inside the cisternal space totally dissected. The suitability of a cow brain as a training model for sylvian fissure microdissection was evaluated as three groups; bad, good, and perfect.
Ten uncovered fresh cadaveric cow brain were used in this experimental feasibility study. The suitability of the experiment for training model was evaluated as bad in (2) 20% and as good in (6) 60% of the cadaveric cow brains. In the remaining (2) 20% of the brain dissection was evaluated as perfect.
In conclusion,performing the sylvian cistern and vascular dissection and protecting the neural and vascular tissue from the mechanical bruising effect of metallic microsurgical instruments is feasible as shown in this study. We believe that this experimental training model will improve practical microsurgical dissection training in microneurosurgery and adequately performing of the dissection. Additionaly, it provides adequate performance for the microsurgical intervention around the sylvian cistern.
