Aim: To present our series of cerebellopontine angle (CPA) meningiomas, and to provide some innovative surgical steps for safe removal of these tumors.
Material And Methods: The clinical, radiological, and surgical characteristics of 32 patients with meningioma in the CPA were retrospectively analyzed. A statistical analysis was performed to determine the factors that affect the incidence of complication.
Results: The mean age was 49.5 yr, and 87.5% of patients were men had World Health Organization (WHO) grade I meningioma, while the remaining patients had WHO grade II tumors. The mean tumor volume was 33.98 mL, and gross total resection was performed on 65.6% of the patients. Preoperative tumor size/extension and extent of resection were related with the development of complications.
Conclusion: CPA meningiomas are challenging tumors to remove safely. Important risk factors for the development of postoperative complications include tumor size and extent of resection.

Background: Surgery for tumors in the cerebellopontine angle is always a significant challenge due to the densely packed neurovascular structures, the narrow deep location, and the complex relationship between the lesions and surrounding neurovascular structures. Recently, great attention has been given to the neuroendoscope for its exclusive advantages, which have added a new dimension to many classical microscopic surgeries. However, the feasibility and advisability of fully endoscopic neurosurgery for cerebellopontine angle tumors remain to be further evaluated.

Background And Objectives: The intraosseous subarcuate loop (SL) is a unique variant of the anterior inferior cerebellar artery (AICA), where a loop of the artery is trapped in the petrous bone's subarcuate fossa (SF). Recognizing this variant is crucial for planning cerebellopontine angle (CPA) surgeries; however, data regarding its frequency and management vary in the published literature. A cohort from a single center was studied using MRI to assess its prevalence, and the findings were compared with the existing literature.

Background: Full-endoscopic microvascular decompression (fE-MVD) is an emerging treatment option for trigeminal neuralgia (TN). However, the risk factors associated with postoperative recurrence of TN after fE-MVD procedure remain controversial. The aim of the present study was to summarize the surgical technique of fE-MVD for the treatment of TN and to develop a predictive model for recurrence at 1 year postoperatively based on independent risk factors.

Paragangliomas are slow-growing, extra-adrenal neuroendocrine tumors with rare intracranial presentation. Although benign, they can be locally aggressive tumors causing bone destruction and compression related symptoms. We report the case of a 19 years old, normotensive female who presented with headache and vertigo for the past six months.

Background: Ganglioneuroma represents an uncommon benign tumor arising from the sympathetic nerves, and its development from the fifth nerve is an infrequent entity. Few ganglioneuromas arising from the fifth nerve have been discussed in literature. The authors describe the second pediatric ganglioneuroma arising from the fifth nerve.
