Pterional, trans-sylvian approach is a basic and most popular neurosurgical procedure used in surgical treatment of various vascular, tumor and other lesions located in and around the sellar and parasellar region. It has several benefits such as a shorter working distance, anatomical familiarity, lesser need for brain retraction with wide sylvian dissection, ability of extension with some modification. All anterior circulation aneurysm except pericallosal origin aneurysm and some aneurysm of posterior circulation can be approached with pterional, trans-sylvian method. The authors discribe the procedure of pterional trans-sylvian approach.

Intraorbital expansion is not rare in frontoethmoidal mucoceles and various rhinological surgeries have been reported for the management of this condition. However, although intraorbital mucoceles are apt to be accompanied by ophthalmological or neurological complications, their treatment by neurosurgical procedures has been reported considerably less frequently than that by rhinological approach. The authors report a patient with intraorbital mucopyocele that was extended from the frontoethmoidal sinus but separated by the thick fibrous septum. The patient had suffered from progressive proptosis with orbital pain and was successfully treated with transorbital complete removal of cyst by the subfrontal extradural approach. We suggest that an subfrontal transorbital approach such as this method is needed for complete marsupialization of an intraorbital mucocele and to prevent recurrence, especially in cases like our presentation.

ABSTRACT: Meningiomas are the most common primary intracranial neoplasm with diverse pathological types and complicated clinical manifestations. The fifth edition of the WHO Classification of Tumors of the Central Nervous System (WHO CNS5), published in 2021, introduces major changes that advance the role of molecular diagnostics in meningiomas. To follow the revision of WHO CNS5, this expert consensus statement was formed jointly by the Group of Neuro-Oncology, Society of Neurosurgery, Chinese Medical Association together with neuropathologists and evidence-based experts. The consensus provides reference points to integrate key biomarkers into stratification and clinical decision making for meningioma patients.

Precision neurosurgery concept as well as the establishment of it's technical platform, have played essential roles in promoting the modern surgical management of brain gliomas in China.In the past decade,the multidisciplinary integration of medical sciences and technology innovations has significantly promoted the clinical implementation of new imaging and novel navigation technology.With active clinical translational research and practice,precision neurosurgery has developed from "startup prologue" (simple anatomical navigation) to "precision neurosurgery 1.0" (intraoperative MRI with multimodal neuronavigation),followed by "precision neurosurgery 2.0" (informative and systematic upgrading).In the past decade,Chinese researchers have made significant and remarkable achievements in precision neurosurgery through continuous efforts and innovation.In the future,state-of-art technologies such as artificial intelligence on deep learning and machine learning,multimodal real-time navigation,intraoperative optical imaging,and targeted molecular imaging technology will promote the development of precision neurosurgery in a coordinated manner, leading to the advent of "precision neurosurgery 3.0".

The protection of language function is one of the major challenges of brain surgery. Over the past century, neurosurgeons have attempted to seek the optimal strategy for the preoperative and intraoperative identification of language-related brain regions. Neurosurgeons have investigated the neural mechanism of language, developed neurolinguistics theory, and provided unique evidence to further understand the neural basis of language functions by using intraoperative cortical and subcortical electrical stimulation. With the emergence of modern neuroscience techniques and dramatic advances in language models over the last 25 years, novel language mapping methods have been applied in the neurosurgical practice to help neurosurgeons protect the brain and reduce morbidity. The rapid advancements in brain-computer interface have provided the perfect platform for the combination of neurosurgery and neurolinguistics. In this review, the history of neurolinguistics models, advancements in modern technology, role of neurosurgery in language mapping, and modern language mapping methods (including noninvasive neuroimaging techniques and invasive cortical electroencephalogram) are presented.

Intracranial Rosai-Dorfman disease (RDD) is a rare clinical histiocytosis proliferative disease. A 12-year-old boy with dizziness and headache for 1 month was admitted into Pediatric Neurosurgery of Xiangya Hospital, Central South University. The patient underwent total tumor resection and postoperative application of hormones and chemotherapy. During follow-up of 8 months, patient's condition was stable and no tumor recurrence was observed. For patient with a trend of tumor progression, stereotactic biopsy can help to confirm the diagnosis and determine the surgical strategy such as disposal of bone flaps. The treatment is mainly based on surgical intervention, supplemented by radiotherapy, chemotherapy and hormone therapy. Without affecting the nerve function, the surgeon should try to completely resect the tumor.
