The skill and techniques of a surgeon, and what we may call his philosophy, are faithfully reflected in the operative results he obtains in meningioma and neurinoma cases. Total removal of a meningioma is nearly always possible and must be attempted. Radical removal, however, may sometimes cause severe and permanent deficits; the surgeon should take care not to overestimate his own skill. The postoperative condition of the patient is the most important matter, and this must be assured even if it means that a small portion of the tumor has to be left behind. Today, follow-up study is easily carried out with the aid of the CT scan; furthermore the majority of meningiomas grow very slowly. Even if radical removal without deficits is difficult at present and reoperations are sometimes difficult due to adhesion, it may become possible 10 years hence with further technical advancements.
