Expert Consensus on Procedures and Operations of Navigation-guided Needle Biopsy Techniques for Skull Base Tumours.

Skull base surgery is an interdisciplinary subject. The anatomical structures in the skull base related to oral and maxillofacial surgery include the parapharyngeal space, the pterygopalatine fossa and the infratemporal space. This operative area is one of the most challenging surgical areas in oral and maxillofacial surgery due to its deep site, complex anatomy and high risk.

Evolution of transmaxillary approach to tumors in pterygopalatine fossa and infratemporal fossa: anatomic simulation and clinical practice.

Background: The endoscopic transnasal approach has been proven to have advantages on the removal of the tumors in pterygopalatine fossa (PPF) and infratemporal fossa (ITF). Herein, this study aimed to describe a modified approach for resection of the tumors in these areas, both in cadaveric specimen and clinical patients.

Methods: The 20 adult cadaveric specimens and five patients with tumors in PPF and ITF were enrolled in this study.

[Surgical treatment of paraclinoid aneurysms].

Objective: To explore the surgical treatment of paraclinoid aneurysms and evaluate the safety and efficacy of microsurgical clip and endovascular embolization of paraclinoid aneurysms.

Methods: The data of 28 patients with 30 paraclinoid aneurysms receiving surgical treatment were retrospectively analyzed. According to Barami classification, 4 aneurysms were type Ia, 5 aneurysms type Ib, 13 aneurysms type II, 4 aneurysms type IIIa, 1 aneurysm type IIIb, and 3 aneurysms type IV.

[Application of superficial temporal artery to middle cerebral artery bypass in treatment of cerebral artery steno-occlusive disease].

Objective: To explore the effect of superficial temporal artery to middle cerebral artery(STA-MCA) bypass in treatment of cerebrovascular disease.

Methods: Fifty-two patients with atherosclerotic carotid artery occlusion or middle cerebral artery occlusion or moyamoya disease were included in this study. There were both clinical ischemic manifestation and hemodynamic dysfunction detected by perfusion CT in all the patients.

Virtual reality system for diagnosis and therapeutic planning of cerebral aneurysms.

Background: The virtual reality (VR) system can provide the neurosurgeon to intuitively interact with and manipulate the three dimensional (3-D) image similarly to manipulate a real object. It was seldom reported that the system was used in diagnosis and treatment of cerebral aneurysms. This study aimed to investigate the application of VR system in diagnosis and therapeutic planning of cerebral aneurysms.

[A case report of squamous cell carcinoma arising in a patient with meningomyelocele].

Meningomyelocele combined with squamous cell carcinoma is rare in literature. In this article, we report the clinical and treatment of a patient with meningomyelocele and squamous cell carcinoma and discuss its mechanism, clinical feature, therapy and prognosis.The patient was a 11-year-old Chinese boy.

[Congenital bilateral perisylvian syndrome: a case report].

Congenital bilateral perisylvian syndrome (CBPS) is rare in literature, especially in China. In this article, we report the clinical and treatment of a patient with CBPS and discuss its mechanism, clinical features and therapy. This patient was a 28-year-old man.
