The auditory brainstem response (ABR) may be a predictor of postoperative cochlear nerve function. In this study, the course of intraoperative ABR monitoring was analyzed to find predictive markers for postoperative hearing function. ⋯ Intraoperative ABR development is a predictive factor for postoperative hearing outcome. Deterioration should be avoided, because ABR improvement as a result of good status at the beginning of surgery could not be assumed.

To analyze overall trends of elective cervical spine surgery in the United States from 2003 to 2013 with the goal of determining whether the economic downturn had an impact. ⋯ The overall elective cervical spine surgery trend was not likely impacted by the economic downturn. Posterior cervical fusions grew significantly from 2003 to 2013, whereas ACDFs and posterior decompressions decreased.

Review Meta Analysis
Cavernous Sinus Invasion in Pituitary Adenomas: Systematic Review and Pooled Data Meta-analysis of Radiological Criteria and Comparison of Endoscopic and Microscopic Surgery.
Despite the substantial impact of cavernous sinus invasion (CSI) in pituitary adenoma surgery, its radiologic determination has been inconsistent and variable, and the role of endonasal endoscopic surgery has been unclear. This is a systematic review and pooled data meta-analysis of the literature to ascertain the best radiologic criteria for CSI and verify the efficacy and safety of an endonasal endoscopic approach. ⋯ Knosp 3-4 remains the best objective indicator of CSI. Microscopy tends to overestimate intraoperative CSI compared with endoscopy. Among pituitary adenomas with CSI, GTR in endoscopic series is higher than microscopy and improves with experience without significant additional morbidity.

Review Case Reports Meta Analysis
Invasive Giant Cell Tumor of The Lateral Skull Base: A Systematic Review, Meta-analysis and Case Illustration.
The current literature regarding cranial giant cell tumor (GCT) management includes scattered case reports and small case series. We present a comprehensive literature review and meta-analysis on this subject, along with a case report describing our management of a patient with temporal GCT. ⋯ GCTs of the skull commonly affect young adults, with an equal sex distribution, and are most often centered in temporal bone. GTR is associated with the lowest recurrence rate and should be the goal of treatment. If GTR cannot be achieved, the combination of STR and radiation results in a similar recurrence rate. With the advent of denosumab, there is now a role for chemotherapy in the treatment of GCTs.
