Surgery is the preferred option for lumbar spinal stenosis (LSS) when conservative methods cannot meet the needs. Recent advancements in surgical techniques have brought various new methods for treating LSS. ⋯ Endoscopic decompression can effectively improve short-term back VAS scores and reduce hospital stays, while IPSD is effective in reducing long-term back VAS scores with minimal surgical duration and blood loss.

Video-assisted debriefing (VAD) is promising for medical skill training, but its effectiveness requires further exploration. The aim of this study was to investigate the effectiveness of point-of-view VAD in spinal surgery training. ⋯ VAD is more effective than traditional verbal debriefing for improving residents' surgical skills, particularly for obtaining a more comprehensive understanding of anatomical structures, imitating detailed surgical techniques as well as promoting initiative. However, in terms of mastery of surgical skills, VAD is not significantly beneficial for tactile perception of the surrounding tissue, indicating that a certain amount of practice is still necessary.

To investigate the treatment effect and prognosis of posterior fossa epidural hematoma in children by different surgical methods. ⋯ The effect of minimally invasive skull trepanation and drainage in the treatment of posterior fossa epidural hematoma in children is similar to that of craniotomy hematoma removal, but the operation is simpler, less trauma, less intraoperative bleeding, and short operation time, which is worthy of clinical application.

Although there are many reports on the efficacy of preoperative embolization for meningioma, such as a reduction in intraoperative blood loss, its efficacy for vestibular schwannoma remains unclear. Feeding arteries of vestibular schwannomas include branches from the anterior inferior cerebellar artery and internal carotid artery, in addition to the branches from the external carotid artery (ECA). However, it has been reported that the embolization of feeding arteries from the anterior inferior cerebellar artery and the internal carotid artery has a high risk of complications. Therefore, we retrospectively analyzed the effects of preoperative embolization of only the feeding arteries from the ECA for vestibular schwannomas, particularly regarding its volume reduction effect. ⋯ Preoperative embolization of only the feeding arteries from the ECA may be an effective adjunctive treatment for vestibular schwannomas, given the significant volume reduction effect achieved within several days after embolization, in addition to reducing intraoperative blood loss.

Calcification in pituitary adenomas is a rare occurrence and its differential diagnosis typically includes other sellar masses. Common calcifications in pituitary adenomas are classified into 2 morphological forms: capsular (eggshell-like) and multiple small nodular calcifications located within the adenoma. Also, there is a pituitary stone term. This study aims to present the results of calcified pituitary adenoma case series who underwent endoscopic endonasal approach (EEA) and the clinical, histopathological characteristics and surgical outcomes of these cases. ⋯ Preoperative radiological evaluation, intraoperative classification of calcification, and postoperative histopathological assessments are crucial in the treatment of calcified adenomas. Bases on these findings, the EEA, with its advantages, is an approach that can be effectively used in the management of these calcified adenomas.
