Endoscopic third ventriculostomy (ETV) is a routinely used alternative to ventriculoperitoneal shunt in patients with obstructive hydrocephalus. We attempted to determine the usefulness of the surgeon's intraoperative impression and postoperative period intracranial pressure monitoring that may help guide clinicians in predicting the early functional outcome of ETV. ⋯ ETV is a valuable means of treating obstructive hydrocephalus. By considering the surgeon's intraoperative impression and postoperative ICP monitoring course, some of the uncertainty around its functional outcome can be overcome. The surgeon's impression and the ICP monitoring offer approximately the same predictive quality for ETV outcome.

Assessing the academic impact and output of scientists and physicians is essential to the academic promotion process and has largely depended on peer review. The inherent subjectivity of peer review, however, has led to an interest to incorporate objective measures into more established methods of academic assessment and promotion. Journal impact factor has been used to add objectivity to the process but this index alone does not capture all aspects of academic impact and achievement. ⋯ This review critically analyzes indices that are currently available to evaluate the academic impact of scientists and physicians. These indices include the total citation count, the total number of papers, the impact factor, as well as the "h" index with eight of its most common variants. The analysis focuses on their use in the field of academic neurosurgery, and discusses means to implement them in current review processes.

Surgical treatment for severe circumferentially fixed cervical kyphosis has been challenging. Both anterior and posterior releases are necessary to provide the cervical mobility necessary for fusion in a corrected position. ⋯ Severe fixed cervical kyphosis was treated successfully by the use of circumferential osteotomy and pedicle screw fixation. The surgical sequence described in this report is a reasonable approach for severe circumferentially fixed cervical kyphosis and short segment fixation can be achieved using pedicle screws.
