Study to Evaluate the Effectivity and Safety of BIOSCAFF®H Compared to DuraGen®, in Patients Undergoing Dural Repair

Study in which the presence or absence of symptoms or any health condition is observed and recorded 30 days after a cranial surgery in which the physician places a material or graft, either BIOSCAFF®H or DuraGen®, into the skull; this material allows the regeneration of tissue that makes up one of the layers of the brain that was affected before or during surgery. The primary hypothesis of this study is that there will be no more than a 10% difference in outcomes between the BIOSCAFF®H device and the active comparator, DuraGen®, with respect to the incidence of cerebrospinal fluid leak or the presence of pseudomeningocele.
