Objective: The aim of this experimental study was to evaluate the feasibility of using fresh cadaveric cow brain as in a training model for microsurgical dissection of sulcus, cisterns, and fissure. Methods: Experimental microneurosurgical activities in this study were performed under the operating microscope. Bilateral sylvian cisterns, interhemispheric fissure, and hemispheric sulcus of the fresh cadaveric cow brain were used as an interested area for this experimental study. The dissection was continued reaching down to the floor of the cistern and total dissection of the middle cerebral artery inside the cisternal space. The suitability of a cow brain as a training model for sylvian fissure microdissection was evaluated as three groups; bad, good, and perfect. Results: Ten uncovered fresh cadaveric cow brains were used in this experimental feasibility study. The suitability of the experiment for training model was evaluated as bad in (1) 10% of the fresh cadaveric cow brains. The suitability was found as good in (6) 60% of the procedures. In the remaining (3) 30% of the brain dissection, the suitability of the experiment was evaluated as perfect. Conclusion: In conclusion, performing the sulcal, cisternal, and fissural dissection and protecting the neural and vascular tissue from the mechanical bruising effect of metallic microsurgical instruments are feasible as shown in this study. We believe that this training model will contribute to the practical micro-neurosurgery. Additionally, it provides adequate performance for the microsurgical intervention.
