Progress in endoscopic surgery for pineal region tumors
ZHANG Xiaobiao
Abstract：Located at the center of the brain,pineal region tumors are challenging for neurosurgical procedures due to their deep anatomical position and the complex surrounding neurovascular structures.The maturity of endoscopic techniques has compensated for the limitations of traditional microscopic surgery in terms of field exposure,anatomical identification,and surgical safety.This article systematically reviews the progress in the application of endoscopic techniques in pineal region tumor surgery,focusing on the selection of surgical approaches such as the supracerebellar infratentorial approach(SCITA,midline and paramedian methods)and the occipital transtentorial approach(OTTA),and emphasizes the precise protection of key structures like the internal cerebral veins.By analyzing tumor resection strategies for different pathological types,this article proposes individualized strategies for en bloc resection or partial lesion preservation,combined with postoperative chemotherapy and radiotherapy to improve therapeutic outcomes.Furthermore,endoscopic techniques have demonstrated unique advantages in the management of obstructive hydrocephalus(such as endoscopic third ventriculostomy)and tissue biopsy.The application of 3D endoscopic technology has further enhanced the stereoscopic perception of deep structures,significantly improving surgical cognition and operational safety.Future innovations in endoscopic technology are expected to promote the development of pineal region tumor surgery towards minimally invasive,precise,and safe directions.
