PURPOSE
To describe a case of conjunctival hyperaemia and proptosis of the right eye.
METHODS
Three-dimensional computed tomography (CT) was performed to reveal the size and position of a lesion of osseous density extending into the right orbit. The lesion was then excised using a right paranasal transcutaneous approach.
RESULTS
The pathology report suggested ethmoidal osteoma. The postoperative course was uncomplicated and the lesion did not recur during a 5-year follow-up period. Repeated postoperative ophthalmic examinations revealed preservation of visual acuity and visual fields postoperatively.
DISCUSSION
Diagnosis is based on imaging studies, especially CT and three-dimensional CT scans. A three-dimensional CT scan is critical in understanding the actual dimensions of the tumour and its relations with other structures. Surgical removal is indicated in cases with orbital matrix compression and displacement. A transcutaneous paranasal approach allows for increased exposure of affected structures.
目的
描述一例右眼结膜充血和眼球突出的病例。
方法
进行三维计算机断层扫描（CT）以显示延伸至右眼眶的骨密度病变的大小和位置。然后采用经鼻右侧经皮入路切除该病变。
结果
病理报告提示为筛骨骨瘤。术后过程无并发症，在5年随访期内病变未复发。术后多次眼科检查显示术后视力和视野得以保留。
讨论
诊断基于影像学检查，尤其是CT和三维CT扫描。三维CT扫描对于了解肿瘤的实际尺寸及其与其他结构的关系至关重要。对于眼眶基质受压和移位的病例，建议手术切除。经鼻经皮入路可增加对受影响结构的暴露。
