Spinal Nerves Schwannomas: Experience on 367 Cases—Historic Overview on How Clinical, Radiological, and Surgical Practices Have Changed over a Course of 60 Years

Table 1

Onset symptoms and postoperative course. In 199 cases of group A, root of origin was sacrificed. In this group, we found a higher percentage of complete postoperative sensitivity (18%) and motor (3%) deficits. In patients of group B, nerve root was almost always preserved when a positive intraoperative response was seen, and postoperative morbidity significantly decreased.
