Orbital Cavernous venous malformations (OCVMs) are well defined benign lesions. Due to their well encapsulated nature, they are easily dissectible from the surrounding orbital structures. After lymphoid tumours and idiopathic orbital inflammation, orbital Cavernous venous malformations are the third most common intraconal pathology [1-3]. These lesion have a well-defined contrast enhancement on CT and MRI [4]. A Middle aged female presented with history of protrusion of the left eye which was insidious onset and gradually progressive in nature. She had no history of visual disturbances or double vision. Imaging showed an intraconal lesion in the left eye which was inferior and medial to the optic nerve. Given the size and location of the tumour it was easily approachable via endoscopic endonasal transmaxillary transorbital approach [5]. We present a 2-dimensional video of endoscopic endonasal transmaxillary approach to intraorbital intraconal Cavernous venous malformation. Informed consent was taken from the patient. The patient has consented to publish any identifiable image or information pertaining to her. Histopathological examination revealed a cavernous hemangioma. Recovery was uneventful and proptosis resolved completely.
眼眶海绵状静脉畸形（OCVMs）是明确的良性病变。由于其包膜完整，易于与周围眼眶结构分离。眼眶海绵状静脉畸形是继淋巴瘤和特发性眼眶炎症之后，第三常见的眶内病变[1-3]。这些病变在CT和MRI上有明确的对比增强[4]。一名中年女性，有左眼突出病史，起病隐匿，呈渐进性发展。她无视力障碍或复视病史。影像学检查显示左眼有一眶内病变，位于视神经下方和内侧。鉴于肿瘤的大小和位置，可通过鼻内镜经鼻上颌经眶入路轻松到达[5]。我们展示了一段鼻内镜经鼻上颌入路治疗眶内眶内海绵状静脉畸形的二维视频。已获得患者的知情同意。患者已同意公布任何与她有关的可识别图像或信息。组织病理学检查显示为海绵状血管瘤。恢复顺利，眼球突出完全消退。
