The duraplasty is a standard procedure during neurosurgery for injuries and diseases of the brain. The hermetic closure of the dura mater is not always possible with the application of autologous tissues. Synthetic, allogeneic and xenogenic implants, which are currently used, have disadvantages, so the search for the material that would best meet the requirements for a dura mater scaffold continues. The purpose is to study the physical and chemical properties of the composite chitosan/polyethylene oxide (PEO) film and determine the effectiveness of its application for duraplasty in the experiment in vivo; to analyze its ability to biodegradation; to evaluate the effect of chitosan/PEO scaffold on the regeneration of dura matter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
