Chiasmapexy is used to treat empty sella syndrome, and various materials are used for the elevation of the optic chiasm. However, the use of artificial substances may have the risk of graft infection, and fat and muscle may be absorbed over the long term after surgery. In addition, bone and cartilage may be unavailable in adequate amounts. Here, we describe a new technique for chiasmapexy using an iliac crest bone graft. ⋯ The advantages of iliac bone are that it is less likely to absorb and become infected than synthetic materials. This method may be suitable for reoperative cases, especially those wherein the septal cartilage has been removed in a previous surgery. This method will halt visual deterioration and may be one of the considerable options for chiasmapexy operations.

Sacroiliac joint pain can be disabling and recalcitrant to medical therapy. The innervation of this joint is poorly understood, especially its anterior aspect. Therefore, the present cadaveric study was performed to better elucidate this anatomy. ⋯ An improved knowledge of the innervation of the anterior sacroiliac joint might decrease suffering in patients with chronic sacroiliac joint pain.

Microelectrode recording (MER) and intraoperative magnetic resonance imaging (iMRI) have been used in deep brain stimulation surgery for Parkinson disease (PD), but comparative methodology is lacking. Therefore, we compared the 1-year follow-up outcomes of MER-guided and iMRI-guided subthalamic nucleus (STN) deep brain stimulation (DBS) surgery in PD patients. ⋯ MER and iMRI both are effective ways to ensure adequate electrode placement in DBS surgery, but there is no superiority between both techniques, at least in terms of 1-year follow-up outcomes.

Preoperative visualization of the facial nerve could help neurosurgeons to prevent facial nerve injury during vestibular schwannoma surgery. Some studies have addressed diffusion tensor tractography (DTT) for preoperative identification of the facial nerve. However, few studies have focused on tractography-integrated neuronavigation for DTT verification. This study aimed to explore the appropriate DTT tracing parameters and evaluate the effect of intraoperative facial nerve tractography-integrated neuronavigation for verifying the DTT accuracy. ⋯ We consider preoperative DTT with intraoperative tractography-integrated neuronavigation to be a useful method for identifying the location of the facial nerve. This method might improve facial nerve preservation.

Active smoking is a major risk factor for intracranial aneurysm rupture (IAR); however, little is known about the effects of passive smoking on IAR. In China, female passive smoking is widespread and severe. This study aimed to assess whether passive smoking is associated with increased risk of IAR among nonsmoking women. ⋯ Although active current smoking was strongly associated with aneurysm rupture in female patients, passive smoking was not an independent risk factor for aneurysm rupture in nonsmoking women.
