Laser interstitial thermal therapy has become increasingly popular for targeting epileptic foci in a minimally invasive fashion. Despite its use in >1000 patients, the long-term effects of photothermal injury on brain physiology remain poorly understood. ⋯ Prolonged incompetence of the blood-brain barrier produced by thermal ablation may provide a path for delivery of macromolecules into perilesional tissue, which could be exploited for therapeutic benefit, but rarely it may result in autoimmune central nervous system inflammatory conditions.

Keyhole approaches are under investigation for skull base tumor surgery. They are expected to have a low complication rate with the same successful resection rate compared with endoscopic endonasal procedures. In this study, we compare our current series of tuberculum sellae meningiomas resected via an endoscopic endonasal or microsurgical supraorbital keyhole approach. ⋯ Both approaches provide minimally invasive surgical routes accessing meningiomas of the sellar region. The ideal approach should be tailored to the individual patient considering the tumor anatomy, lateral extension, and the experience of the surgeon with both surgical approaches. We suggest using the supraorbital approach for larger meningiomas of sellar region with far lateral extension or broad vascular encasement.

Comparative Study
Impact of Pre-hospital Transportation on Survival in Skiers and Snowboarders with Traumatic Brain Injury.
Prehospital helicopter use and its impact on outcomes in snowboarders and skiers incurring traumatic brain injury (TBI) is unknown. The present study investigates the association of helicopter transport with survival of snowboarders and skiers with TBI, in comparison with ground emergency medical services (EMS), by using data derived from the National Trauma Data Bank (2007-2014). ⋯ Based on our robust statistical analysis of retrospective data, our findings suggest prehospital helicopter transport improved survival in patients incurring TBI after snowboard- or ski-related falls compared with those transported via ground EMS. Policies directed at using helicopter services at remote winter resorts or ski or snowboarding locations should be implemented.

Deep brain stimulation (DBS) may cause various complications including intracerebral hemorrhage (ICH). Because ICH causes devastating neurologic outcomes, various surgical techniques are attempting to reduce the chances of ICH. More importantly, early detection and proper management of postoperative ICH are indispensable. ICH may occur immediately or delayed following DBS; in this study, we analyzed the clinical features of delayed ICH after DBS. ⋯ Our study demonstrates that delayed ICH can occur after DBS even with normal brain CT immediately after DBS. Because ICH can cause serious neurological sequelae, the possibility of delayed ICH after DBS should be considered for the optimal management of patients.

Sometimes during surgery for cubital syndrome an anomalous muscle called the epitrochleoanconeus is encountered. Different surgical strategies on how to decompress the ulnar nerve in the presence of this muscle have been proposed, including transection of the muscle, resection, or subcutaneous transposition of the ulnar nerve. Because of the low incidence, there is no consensus on what type of surgical treatment can best be performed. In the present study, we prospectively followed a small series of patients, in which the muscle was resected. ⋯ The results of this small prospective case series show that excision of the epitrochleoanconeus muscle in patients with cubital tunnel syndrome frequently leads to complete recovery. Further support for this surgical strategy was found from histopathologic analysis of the resected muscles.
