鼻内镜联合外侧开眶切除视神经鞘脑膜瘤一例

Nasal endoscopy combined with lateral orbitotomy for resection of optic nerve sheath meningioma: a case report

视神经鞘脑膜瘤(ONSM)是一种起源于视神经鞘蛛网膜细胞的良性肿瘤。由于它易于向视神经管内和颅内蔓延,加上眼眶解剖的特殊性,传统手术方式很难彻底将其切除,且术后复发率较高,使得ONSM的切除成为临床手术难题。该文报道1例经鼻内镜联合外侧开眶手术治疗ONSM患者,以期为治疗ONSM提供新的手术思路。

Optic nerve sheath meningioma (ONSM) is a benign tumor derived from the arachnoid cells of the optic nerve sheath. Because ONSM tends to invade into the optic canal and intracranial tissues combined with the particularity of orbital anatomy, it is difficult to completely resect the ONSM by conventional surgical methods. The high postoperative recurrence rate makes the resection of ONSM become a challenging surgery in clinical practice. In this article, one ONSM patient undergoing nasal endoscopy combined with lateral orbitotomy was reported, aiming to provide novel ideas for the surgical resection of ONSM.
