摘要
目的 评价各种影像学检查对眼眶皮样囊肿的诊断价值,总结眼眶皮样囊肿的手术经验。方法 利用15年期间诊治的眼眶皮样囊肿17例做回顾性分析,对比各种检查结果的特征,分析不同部位囊肿的手术方式和术中处理。结果 X线检查能粗略反映眼眶骨骼改变。超声多普勒反映肿瘤的血流情况。B超、CT、MRI均可确定病变位置并提示病变的性质,但B超能较好显示病变内结构和动态,CT发现病变及确定空间位置较准确,MRI上信号高低与脂质、H+ 含量有关。表浅囊肿易分离、摘除;深部囊肿需复杂的手术方案。囊肿壁的完整摘除是手术成功的关键。结论 上述影像检查均对眼眶皮样囊肿诊断有帮助,CT检查最有价值。超声、MRI与CT检查相结合,能得出最佳定性、定位诊断。术中必须彻底清除囊肿。
Objective To evaluate the diagnostic role of the moderm photographic methods used for orbital dermoid cyst,to summary the experiments of surgery in orbital dermoid cyst.Methods To retrospectively analyse 17 cases of orbital dermoid cyst diagnosed and cured within 15 years.Results X-ray can show partly the change of the orbital wall.The blood flow pattern of the tumors was evaluated with color Doppler ultrasoud examination.Each of B-scan,CT scan and MRI can locate and show the nature of the lesions.B-scan has a better value to display internal structure and dynamics of the lesions.CT can discover the lesions and show exactly their locations.The result of MRI examination was connected with sebum and H^+.The superficial lesions can easily be sequestrated and excised;the deep lesions require complex surgical management.The excision entirely of the capsular wall is crucial to the surgery.Conclusions The very photographic method can give help to diagnose orbital cyst.CT scan is the most important examination.The most valuable diagnosis in localizing and showing nature can be got throughout combining B-scan,MRI with CT.The lesions must be excised entirely lest to recurrent.
