Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, describes a disease of poorly understood pathophysiology with a specific set of signs and symptoms including potentially irreversible and blinding visual loss. Optic nerve sheath fenestration (ONSF) is a well-described surgical treatment for patients with IIH and progressive visual loss despite maximally tolerated medical therapy. A number of optic nerve access procedures have been described including medial transconjunctival, superomedial lid crease, and lateral orbitotomy with and without bone takedown. The purpose of this report is to describe a revised lateral approach for temporal optic nerve access that obviates the need to traverse through the intraconal fat of the central surgical space in the previously described lateral approach techniques.
特发性颅内高压（IIH），也称为假性脑瘤，是一种病理生理学尚不清楚的疾病，具有一组特定的体征和症状，包括潜在的不可逆性致盲视力丧失。视神经鞘开窗术（ONSF）是一种针对IIH患者且尽管接受了最大耐受量的药物治疗仍出现进行性视力丧失的患者的已被充分描述的外科治疗方法。已经描述了多种视神经入路手术，包括经结膜内侧入路、睑皱襞上内侧入路以及有或无骨切除的外侧眶切开术。本报告的目的是描述一种改良的外侧入路用于颞侧视神经入路，该入路避免了在先前描述的外侧入路技术中穿过中央手术空间的锥内脂肪的需要。
