The outcomes of recent endoscopic surgery of nonfunctioning pituitary adenomas (NFPAs) are controversial when compared with traditional microscopic surgery. We aimed to assess the outcomes of endoscopic transsphenoidal surgeries performed by 1 surgeon with 7 years of experience and elucidate the predictive factors for surgical outcomes for NFPAs. ⋯ Endoscopic transsphenoidal surgery by a well-experienced surgeon was an effective and safe treatment for NFPAs, but the hormonal outcomes were not changed compared with previous reports of microscopic surgery. Large tumor size and cavernous sinus invasion were still the barriers for achieving total resection.

Moyamoya disease associated with tuberculum sellae meningioma and cavernous sinus hemangioma: case report.
Primary moyamoya disease associated with skull base tumors has been reported only rarely in the literature. Surgical treatment can be complicated due to the compensatory collateral circulation through meningeal and leptomeningeal anastomosis. A standard frontotemporal craniotomy may interrupt critical transdural anastomoses. ⋯ With careful bone flap design, moyamoya disease and skull base tumors can be treated simultaneously. Care should be taken to avoid interruption of critical dural-pial collaterals and injury to fragile moyamoya vessels.

Hydrocephalus is a frequently encountered complication in the context of aneurysmal subarachnoid hemorrhage (aSAH). Here, we performed an external validation of the recently proposed postsubarachnoid shunt scoring (PS3) system, which aims to stratify patients presenting with aSAH based on their relative risk of requiring ventriculoperitoneal (VP) shunt insertion. ⋯ Data from this study validated the previously proposed PS3 system, which was found to more accurately predict shunt-dependent chronic hydrocephalus in patients with aSAH compared with other such systems in the neurosurgical literature, such as the chronic hydrocephalus ensuing from SAH score, Barrow Neurological Institute, and shunt dependency in aSAH systems.

Although most posterior communicating artery (PCoA) aneurysms can be clipped easily with excellent results, some require anterior clinoidectomy for safe and complete clipping. ⋯ In case of ruptured PCoA aneurysm surgery, the distances from the ACP tip to the aneurysmal proximal neck and from the ACP line to the aneurysmal proximal neck were both found to be useful predictors of whether anterior clinoidectomy was required.

To investigate clinical parameters of anterior cervical discectomy and fusion (ACDF) treatment and outcomes using osseous allografts in different age groups, study the postoperative results of restoration of lordosis, and evaluate the utility of bone allografts for ACDF, including graft subsidence. ⋯ Osseous allografting can excellently restore cervical lordosis regardless of age and is an excellent graft choice for ACDF. Patients of advanced age with comorbidities should not be denied surgery.
