A sphenoid sinus mucocele extending into the middle cranial fossa and the pterygomaxillary fissure was decompressed using an endoscope in combination with a navigation system. A 59-year-old woman was admitted with a 3 month history of retro-ocular pain and right sided exophthalmos. To evaluate the cystic lesion, a fibreoptic endoscope was inserted into the cyst through an erosive defect in the temporal bone. The histopathological appearance of cyst wall tissue confirmed the diagnosis of mucocele. After 4 months, the mucocele had refilled and the exophthalmos had recurred. At reoperation, the cyst was fenestrated using a rigid endoscope combined with a navigation system inserted via a sublabial transmaxillary approach. The proper site of cyst fenestration was precisely determined using the navigation system, permitting complete evacuation of this large lesion with minimal invasiveness.
一名患有蝶窦黏液囊肿并已延伸至中颅窝和翼上颌裂的59岁女性，通过使用内窥镜结合导航系统进行了减压手术。该女性因眼后疼痛和右侧眼球突出3个月入院。为评估囊性病变，通过颞骨的侵蚀性缺损将纤维内窥镜插入囊肿。囊肿壁组织的组织病理学表现确诊为黏液囊肿。4个月后，黏液囊肿再次充盈，眼球突出复发。再次手术时，通过唇下经上颌入路，使用硬式内窥镜结合导航系统对囊肿进行开窗。利用导航系统精确确定囊肿开窗的合适部位，以最小的侵袭性实现了对这个大病变的完全清除。
