Post Surgical Management of WHO Grade II Meningiomas: Our Experience, the Role of Gamma Knife and a Literature Review.

Grade II meningiomas are rarer than Grade I, and when operated on, bear a higher risk of local recurrence, with a 5-year progression free survival (PFS) ranging from 59 to 90%. Radiotherapy (RT) or radiosurgery, such as Gamma Knife radiosurgery (GKRS) can reduce the risk of relapse in patients with residual disease, even if their role, particularly after gross total resection (GTR), is still under debate. Main goal of this study was to compare the outcomes of different post-surgical management of grade II meningiomas, grouped by degree of surgical removal (Simpson Grade); next in order we wanted to define the role of GKRS for the treatment of residual disease or relapse.

Safety and feasibility of lumbar drainage in the management of poor grade aneurysmal subarachnoid hemorrhage.

The use of lumbar drain (LD) in the aneurysmal subarachnoid hemorrhage (aSAH) has been described to reduce cerebral vasospasm and delayed cerebral ischemia (DCI), with a lack of studies referring to high grade population. The purpose of our study is to assess safety and feasibility of LD in the poor grade aSAH population subjected to endovascular aneurysm occlusion. Twenty-four consecutive poor grade aSAH patients, defined as grade IV and V according to World Federation of Neurological Surgeons (WFNS) classification, subjected to endovascular aneurysm occlusion, were retrospectively reviewed.

Bone resorption in autologous cryopreserved cranioplasty: quantitative evaluation, semiquantitative score and clinical significance.

Background: Changes after reimplantation of the autologous bone have been largely described. However, the rate and the extent of resorption in cranial grafts have not been clearly defined. Aim of our study is to evaluate the bone flap resorption (BFR) after cryopreservation.

Usefulness of Ultrasound-Guided Microsurgery in Cavernous Angioma Removal.

Background: Primary elements of surgical treatment of cavernous angiomas (CAs) are precise lesion identification and optimal trajectory determination. Navigation techniques allow for better results compared to microsurgery alone. In this study, we examined the benefits of intraoperative ultrasound (IOUS) use as an adjunct to standard localization systems.

Fronto-orbitozygomatic approach: functional and cosmetic outcomes in a series of 169 patients.

OBJECTIVE Advantages of the fronto-orbitozygomatic (FOZ) approach have been reported extensively in the literature; nevertheless, restoration of normal anatomy and the esthetic impact of surgery are increasingly important issues for patients and neurosurgeons. The aim of this study was to analyze functional and cosmetic outcomes in a series of 169 patients with different pathologies who underwent surgery in which the FOZ approach was used. METHODS Between January 2000 and December 2014, 250 consecutive patients underwent surgery with an FOZ approach as the primary surgical treatment.

Safety of transsphenoidal microsurgical approach in patients with an ACTH-secreting pituitary adenoma.

Purpose: Patients affected by Cushing's disease often have important comorbidities directly linked to hypercortisolism that might enhance the operative risk. We report the safety of transsphenoidal surgery in patients affected by Cushing's disease as compared with patients with nonfunctioning pituitary adenoma.

Methods: We have retrospectively analyzed 142 patients with Cushing's disease and 299 patients with nonfunctioning pituitary adenoma who underwent transsphenoidal surgery performed by a single experienced neurosurgeon between September 2007 and December 2014.
