Ventriculostomy from Paine's point is an effective technique to ensure that the brain is relaxed for aneurysm surgery. This study aimed to use Paine's point for other neurosurgical procedures (except for those that require a pterional approach) by delineation of surface landmarks for identification of Paine's point on the cranium and scalp. ⋯ By accurate surface marking on skull and skin, the use of Paine's point for ventriculostomy performed via an interhemispheric approach or for simple burr-hole surgery was found to be safe and reliable.

To report a new index, the spinal cord (SC) line, and a new classification to predict postoperative recovery effect in patients with multilevel cervical spondylotic myelopathy (CSM). ⋯ The SC line and its classifications can predict postoperative recovery in patients with multilevel CSM.

Pure endoscopic resection has become the most popular surgical approach for pituitary adenoma. Intraoperative magnetic resonance imaging (iMRI) systems have been in use for endoscopic resection of pituitary adenomas. This study aimed to evaluate the effectiveness of iMRI and neuroimaging navigation techniques during endoscopic endonasal transsphenoidal surgery of pituitary adenomas. ⋯ The use of iMRI and neuronavigation not only leads to a higher rate of tumor resection but also helps in detecting and removing hematomas in the surgical area. Follow-up examinations of extent of residual tumor at 3 months postoperatively were consistent with intraoperative results. Residual tumor volume in the suprasellar region was usually less than that observed intraoperatively.

To prospectively evaluate the morphological and structural changes in the trigeminal nerve in patients with trigeminal neuralgia (TN) compared with healthy controls. ⋯ TN is associated with atrophy and a small trigeminal pontine angle in the affected nerve. Nerve atrophy may be a late consequence of chronic physical stress and is likely involved in the pathogenesis of TN. A small trigeminal pontine angle may increase the risk of neurovascular conflict, and thus more likely to result in the genesis of TN.

Cystic dilation of the ventriculus terminalis (CDVT) is a rare anatomic variation that and may become symptomatic. Literature regarding CDVT is limited, and thus the clinical characteristics and management strategy of CDVT are unclear. Here we report 6 cases of CDVT seen in our institution, and provide a review of the current literature. ⋯ CDVT is an extremely rare cause of conus medullaris syndrome with an unclear treatment strategy. Our successful surgical management of 6 cases through cystic-subarachnoid shunting using a T-catheter for CDVT drainage provides a potential option for treating CDVT.
