Smartphones and their apps are used ubiquitously in medical practice. However, in some cases their use can be at odds with current patient data safety regulations such as Canada's Personal Health Information Protection Act of 2004. To assess current practices and inform mobile application development, we sought to better understand mobile device usage patterns among Canadian neurosurgery residents. ⋯ Smartphones are used daily by most neurosurgery residents. Identified usage patterns are associated with perceived gains in efficacy and challenges in privacy and data reliability. We believe creating and improving workflows that address these usage patterns has a greater potential to improve privacy than changing policies and enforcing regulations.

Case Reports
Resolution of Tachyarrhythmia Following Posterior Fossa Decompression Surgery for Chiari Malformation Type I.
Chiari malformation (CM) type I commonly presents with symptoms such as tussive headaches, paresthesias, and, in severe cases, corticobulbar dysfunction. However, patients may present with atypical symptoms lending to the complexity in this patient population. We present a case of a CM patient presenting with atypical cardiac symptoms and arrhythmias, all of which resolved after surgical decompression. ⋯ The surgical management of CM patients presenting with atypical symptoms can be challenging and often lead to delays in intervention. To our knowledge this is the only reported case of a patient presenting with tachyarrhythmia and atypical chest pain with resolution after Chiari decompression. We believe the dramatic improvement documented in the present case should serve to advance Chiari decompression in CM patients presenting with refractory tachyarrhythmia in whom no other discernable cause has been elucidated. Further studies are needed to better correlate the findings and to hopefully establish a criteria for patients that will likely benefit from surgical decompression.

Transnasal endoscopic skull base surgery (SBS) presents a major challenge for inexperienced neurosurgeons because of the complicated anatomic structures, 2-dimensional endoscopic view, limited operative field, and required skills. We designed a personalized multimaterial and multicolor three-dimensional (3D)-printed SBS simulation to reproduce the complex anatomy of the skull base. The fidelity and feasibility for anatomic education and surgical training were assessed. ⋯ The 3D-printed SBS simulation is a practical, economical, high-fidelity model. It has great potential for anatomic education and operative training in transnasal endoscopic surgery.

The impact of obesity on spine surgery has been studied extensively, but only a few investigations have been focused on minimally invasive spinal fusion techniques and complication rates in normal-weight, preobese, or obese patients. Obesity was found to be a risk factor for intraoperative complications. Published data tend to favor minimal access surgery techniques (MAST) for obese patients. In a prospective study, we assessed the perioperative and postoperative complications of MAST in a large population of 187 patients. ⋯ We conclude that preobese and obese patients are good candidates for MAST because BMI did not affect complication rates or duration of surgery.

Application of Rubber Band with Hooks on Both Ends for Vagus Nerve Stimulator Implantation.
Vagus nerve stimulation (VNS) is a valuable therapeutic option for many types of drug-resistant epilepsy. Muscle hooks and carotid endarterectomy rings have been used for cervical delamination preceding the implantation of stimulation electrodes. The attachment on both sides of a rubber band of Kamiyama-style hanging needles, as are used for scalp and dural retraction during craniotomy, yields a useful tool for VNS implantation. Here we report our experience with this method. ⋯ The use of hooks attached to both sides of a rubber band rendered VNS implantation safer by lifting the vagus nerve and standardizing the procedure.
