一側性眼球突出症の病型分類と治療方針

Unilateral Exophthalmos:Diagnostic and therapeuetic procedure

I．はじめに

　一側性眼球突出は眼科，耳鼻科，内科，脳神経外科領域のさまざまな腫瘍性，非腫瘍性病変が含まれ，臨床診断は必ずしも容易でない．しかしながら，眼窩およびその近傍の解剖学的位置関係を現解し，臨床経過，眼球突出の方向，神経眼科的所見に加え，単純X線撮影，CT scanなどの補助検査を施行すれば，診断はより正確につくものと思われる．

　今回われわれは当教室で診断および加療を行った37症例につき，疾患別に整理し，各疾患群の特徴を検討し，手術法についても言及した．

Unilateral exophthalmos related to orbital diseases was analized in 37 cases. Thirty-four out of 37 cases were operated on and histologically verified. The cases included five pseudotumors, five intracranial tumors invading the orbit, four carotid-cavernous fistulas, three mucoceles, two lacrimal gland tumors, two cavernous angiomas, two osteomas, two histiocytomas, two fibrous dysplasias, one neurinoma, one meningioma, one embryonal rhabdomyosarcoma, one metastatic tumor, one venous malformation, one orbital meningoencephalocele, one infraclinoid internal carotid giant aneurysm, and three mass lesions not verified operatively.
