Clinical characteristics and outcomes after trigeminal schwannoma resection: a multi-institutional experience.
Neurosurg Rev
July 2024
Department of Neurological Surgery, Northwestern University Feinberg School of Medicine, 676 N. St. Clair Street, Suite 2210, Chicago, IL, 60611, USA.
Article Synopsis
- The study investigates the clinical characteristics and outcomes of trigeminal schwannoma (TS) surgical resections across two institutions from 2004 to 2022, analyzing data from 30 patients.
- Most patients were middle-aged, with common symptoms including sensory loss and headaches; tumors primarily consisted of mixed cystic-solid types with an average diameter of 3.3 cm.
- Although 87% of patients reported symptom improvements after surgery, there were notable risks, with 17% experiencing temporary and 10% experiencing permanent cranial nerve deficits.
Comparison of Surgical Modalities for Giant Pituitary Adenoma: A Systematic Review and Meta-Analysis of 1413 Patients.

Article Synopsis
- Giant pituitary adenomas (GPAs) represent a small but significant portion of pituitary tumors, and the endoscopic endonasal transsphenoidal (EET) approach has become the preferred surgical method, surpassing older techniques due to improvements in surgical outcomes since 2012.
- A systematic review analyzed various studies to compare EET with microsurgical transsphenoidal (MT) and transcranial (TC) approaches, evaluating factors like gross total resection rates, visual improvement, and complications.
- Results showed that EET had higher gross total resection rates (42%) and better visual outcomes (85%) compared to MT (33% and 73%) and TC (8% and 56
Shaping the curve from the microscopic transsphenoidal to the endoscopic endonasal approach for the sellar region.

Department of Neurosurgery, Hospital de San José, Fundación Universitaria de Ciencias de la Salud, Bogotá.
Article Synopsis
- The study explored the transition challenges from the microscopic transsphenoidal approach (MTA) to the endonasal endoscopic approach (EEA) in skull base surgeries.
- Technical and clinical complications from both surgical methods were analyzed over a year-long early learning curve involving 34 patients.
- Results indicated no significant differences in outcomes such as extent of resection, endocrine function, or visual improvements, with a low complication rate overall.
Microsurgical anatomy of the olfactory filaments in the nasal mucosa.

August 2024
6Department of Neurosurgery, University of Tennessee Health Science Center, Memphis, Tennessee.
Objective: The aim of this study was to examine the distribution of olfactory filaments (OFs) in the nasal mucosa to facilitate preservation of olfactory function in endonasal approaches and preparation of a nasoseptal flap.
Methods: One formalin-fixed and 9 fresh cadaveric silicone-injected specimens with 20 total sides were studied to measure the distance of the OFs to the anatomical landmarks and compare the OF presence in the nasal septum mucosa (NSM) and ethmoidal mucosa (EM).
Results: The mean distance from the first to the last OF was 19.
The Sellar Region as Seen from Transcranial and Endonasal Perspectives: Exploring Bony Landmarks Through New Surface Photorealistic Three-Dimensional Model Reconstruction for Neurosurgical Anatomy Training.

Background: Virtual reality-based learning of neuroanatomy is a new feasible method to explore, visualize, and dissect interactively complex anatomic regions. We provide a new interactive photorealistic three-dimensional (3D) model of sellar region microsurgical anatomy that allows side-by-side views of exocranial and endocranial surfaces to be explored, with the aim of assisting young neurosurgery residents in learning microsurgical anatomy of this complex region.
Methods: Four head specimens underwent an endoscopic endonasal approach extended to the anterior and posterior skull base to expose the main bony anatomic landmarks of the sellar region.
