Optical neuronavigation without rigid pin fixation of the head may lead to inaccurate results because of the patient's movements during awake surgery. In this study, we report our results using a skull-mounted reference array for optical tracking in patients undergoing awake craniotomy for eloquent gliomas. ⋯ A skull-mounted reference array is a simple and safe method for optical neuronavigation tracking without rigid pin fixation of the patient's head.

To investigate the difference in clinical outcome and the position of paddle lead spinal cord stimulation (SCS) between 3-column and 5-column paddle lead SCS in patients with failed back surgery syndrome. ⋯ Although clinical efficacy of SCS using three-column and five-column paddle lead was not significant different from each other, significant inclination of paddle lead in posterior epidural space with significant reduction in T9 canal area were observed in both groups. The degree of inclination in the 5-column group was more than that in the 3-column lead group. Close approximation of paddle lead contacts to dorsal spinal cord with reduced dorsal cerebrospinal fluid space and intraoperative neurophysiologic guidance might have contributed to the high rate of trial success and long-term pain control.

Vision is important for patients with hearing loss caused by neurofibromatosis type 2 (NF2). Tumors adjacent to the anterior visual pathway can potentially impair the vision. Only a few case reports and small-series studies have been reported. ⋯ Tumors adjacent to the anterior visual pathway, although uncommon in patients with NF2, can cause progressive visual loss. Early surgical intervention seems to be the primary treatment strategy, except for in patients' optic nerve sheath meningiomas. If patients adopt a wait and see policy, regular visual examination seems to be mandatory.

Review Case Reports
Skull Base Osseous Arterio-venous fistula - a rare clinical entity : Case report and Literature Review.
To describe a rare clinical entity of intraosseous skull base arteriovenous fistula managed with transvenous fistula embolization. ⋯ Skull base osseous fistulae are uncommon clinical entities and fistulae centered within the sphenoid bone are very rare. The aim of this report was to highlight management issues associated with such a case and review the available literature on the subject.

Review Meta Analysis
Management strategy of osteoblastomas localized in the occipitocervical junction.
The aim of this article was to analyze extracted patient data from the literature and highlight the best treatment options and survival outcomes for osteoblastomas in the occipitocervical region. ⋯ Osteoblastoma is a rare entity in the occipitocervical region, so treatment experiences are limited and mostly based on case reports. To determine the best treatment for these lesions, osteoblastomas should be staged using the Enneking staging system; different methods may be recommended for different stages, and the feasibility of fusion depends on the remaining amount of bony structures and joints. Additional adjuvant therapies may be recommended only in special cases.
