Retrobulbar Soft Tissue Tumor-Three Cases Report
眼球後軟組織腫瘤－三病例報告
摘要
眼球後軟組織腫瘤對整形外科醫師來說是較少處理的疾病。它能影響視力及造成漸進性的眼球外凸。從1991年2月至2000年6月，本院整形外科共治療三例眼球後軟組織腫瘤的患者，病理診斷包括：(1)海綿狀血管瘤；(2)淚腺之混合性腫瘤；(3)淚腺之腺狀囊性癌。術前診斷方法包括詳細眼科學檢查、電腦斷層掃描及組織切片等。良性腫瘤藉由頭皮兩側冠狀(bicoronal)切口，在肉眼直視下將腫瘤切除，同時可避免視神經之傷害與眼外肌活動的限制。惡性腫瘤則以眼剜除術將腫瘤切除。切除後之眼眶缺損則利用橈側前臂自由皮瓣予以重建，該皮瓣不僅提供適量的軟組織體積，而且在病患接受放射與化學治療九個月後仍能維持眼窩的形狀。

Retrobulbar soft tissue tumor is rarely managed by plastic surgeons. It may present with disturbance of visual acuity, and progressive proptosis. From February 1991 to June 2000, we treated three cases of retrobulbar soft tissue tumor including: (1) cavernous hemangioma; (2) mixed tumor of lacrimal gland; and (3) adenoid cystic carcinoma of lacrimal gland. Pre-operative diagnostic methods included detailed ophthalmologic examination, coronary CT scan of orbit, and tissue biopsy. Benign tumor was removed through bicoronal incision, which allowed complete degloving of the orbital content, and removal of the tumor under direct vision. No optic nerve injury or limitation of extraocular muscle was found after operation. Malignant tumor was removed with exenteration of orbit. The resultant defect was resurfaced with free radial forearm flap, which provided adequate soft tissue volume and maintained the orbital socket 9 months after radiotherapy and chemotherapy.
