Purely endoscopic endonasal resection of extracranial trigeminal schwannomas: a descriptive systematic review and institutional case series.

Background: Trigeminal schwannomas (TSs) are uncommon, benign tumors that arise from the trigeminal nerve. They can spread to the middle cranial fossa, posterior fossa, and extracranially (pterygopalatine fossa (PPF), infratemporal fossa, orbita). Among these, extracranial involvement is the least frequent.

Management of Major Arterial Injuries: A Critical Complication of Endoscopic Endonasal Surgery.

Background And Objectives: Endoscopic endonasal surgery (EES) is the preferred approach for treating sellar and parasellar lesions due to its panoramic view and detailed anatomical definition. This study aims to review major arterial injuries during EES, a rare but critical complication associated with high mortality and morbidity rates.

Methods: A retrospective analysis was conducted, including 15 patients from 5640 EES procedures performed between August 1997 and February 2024 at in our center/Department of Neurosurgery.

Endoscopic approach for giant pituitary adenoma: clinical outcomes of 205 patients and comparison of two proposed classification systems for preoperative prediction of extent of resection.

Objective: Giant pituitary adenoma is considered a challenging pathology for surgery owing to its complications and low resection rate. In this study, the authors present their experience of using the endoscopic endonasal approach to treat patients with giant pituitary adenoma, and they aimed to develop a classification system for prediction of extent of resection.

Methods: The institutional medical records of patients diagnosed with giant pituitary adenoma who underwent endoscopic endonasal transsphenoidal surgery between August 1997 and December 2019 were retrospectively reviewed.
