Objective: Assessment of latex film sheet usage to protect the brain tissue against the harmful mechanical effects of metal microsurgical instruments while doing neurosurgical interventions has been the aim of this experimental study.Methods: For this experimental study, brains of cows were grouped as ones for which the latex film sheet was used (Group I) and the others the latex film sheet was not used for (Group II). The latex film sheet was sprawled over the left lateral side of the interhemispheric sulcus in Group I. Additionally, three groups of mechanical traumatic effects were created for the effects of metallic surgical instruments as “minor, moderate and severe”.Results: The results showed that there were 11 minor injured brains in Group I (n=15), with the percentage of 73. 34%. This percentage was 26. 67% with four brains in Group II (n=15) with regard to the minor injuries. When it comes to the moderately injured brain parenchyma, the numbers and percentages were 2 and 13. 33% for Group I, and 8 and 53. 33% for Group II. Severe injury numbers and percentages were 2 and 13. 33% for Group I, and 3 and 20% for Group II. Conclusions: According to the findings of this study, it can be said that the protection of brain tissue from the mechanical injury using the latex film sheet seems to be favorable. The heating effect of the operating microscope’s light is also thought to be prevented to some extent with latex film sheet implementation. On the whole, latex film sheet may have favorable effects for the practical microneurosurgery in protecting the brain tissue.
