This sheet describes the clinical case of a 50-year-old patient who presented with bitemporal hemianopsia. After documenting the presence of a pituitary adenoma by MRI, transphenoidal trans nasal surgery was planned. During surgery, CSF leaking occurred. So the intraoperative management using tissue and biomaterials to support regeneration of the dura mater was required.
The technique involved the application of an equine pericardium membrane in the virtual space between the dura mater and the open sellar floor at the level of the bony breach of the sphenoid sinus, its stabilization with bone fragments and nasal cartilage onto which was adhered some turbinate mucosa taken as needed.
