To evaluate pain control and side effects after gamma knife radiosurgery (GKRS) for classical idiopathic trigeminal neuralgia (TN) with or without neurovascular compression (NVC). ⋯ NVC is not a predictive factor for pain control after GKRS for the treatment of idiopathic TN. Side effects may occur more frequently in patients with NVC at the target coordinate when a root entry zone is used, but the subjective symptoms are not always bothersome.

This study aims to establish a new classification system for proximal anterior cerebral artery (A1) aneurysms and to offer treatment strategies, based on the lessons learned by studying the case reports of 41 patients with A1 aneurysms. ⋯ A1 artery aneurysms are a rare type of aneurysm with unique characteristics. The classification system proposed here accurately summarizes these characteristics to better guide treatment strategies.

In this study, we aimed to identify prognostic factors in anaplastic hemangiopericytoma (AHPC) and clinical behaviors that differentiate primary and secondary AHPC. ⋯ Gross total resection and PRT following surgery are recommended in AHPC. Identifying clinical behaviors that differentiate primary and secondary AHPC improved our understanding of this type of tumor and guided treatment strategies.

Comparative Study Observational Study
Does one size fit all? Examining the Application of Neurosurgery Residency Milestones Developed in the USA to a Taiwanese Culture.
The Milestone Project was launched in 2009, charging specialties to develop specific educational accomplishments required to establish clinical competency. The milestone assessment method was first introduced to Taiwan in 2013 and before applying milestone assessments to our medical education system, the validity and reliability of these questionnaires needed to be evaluated. ⋯ Milestone assessments have high reliability and may be a helpful assessment tool. Although milestone assessment can provide thorough feedback concerning performance and the content of the training program, they may not perfectly suit all residency-training programs, especially in different countries or different cultures. Modifications should be done before applying milestones to different areas; therefore the results can truly reflect the progress and condition of the training and learning process.

Clinical Trial
Complementary relation between direct and indirect bypass in progress of collateral circulation in moyamoya disease.
One of the important aims of surgery for moyamoya disease is to establish indirect revascularization. The purpose of this study was to assess the progress of the middle meningeal artery (MMA) after our novel preservation method and to evaluate the relation between direct and indirect bypass in the chronic stage. ⋯ In moyamoya disease, the MMA could be developed as a pathway for indirect revascularization even after simple preservation, especially in pediatric patients. The progress of the MMA and the STA occurs through their synergistic interaction, and the balance might be decided based on their complementary relations in the chronic stage.
