目的 :探讨眶颅沟通肿瘤的临床特征、种类、诊断方法及手术治疗。方法 :选择 6 0例手术病理或随访结果证实的眶颅沟通肿瘤患者 ,所有患者均行CT扫描 ,5 4例行MRI扫描 ,其中增强扫描 4 2例。 2 0例行视神经管X光像。经翼点入路切除肿瘤 12例 ,经额入路切除肿瘤 2 1例。结果 :最常见的阳性体征是眼球突出、眶压升高和视力下降等 ,最常见的症状是头痛。较多见的眶颅沟通肿瘤是脑膜瘤、骨纤维异常增生症和转移癌。眶颅沟通肿瘤的CT、MRI扫描及视神经孔X光像有一定影像学特征。眶颅沟通的途径包括视神经管、眶上裂和眶颅交界骨壁。全切肿瘤 32例 ,次全切肿瘤 1例。结论 :掌握各种眶颅沟通肿瘤的临床特征、病种分类 ,综合运用CT、MRI和X光等检查方法可提高诊断和鉴别诊断水平。翼点入路和经额入路是眶颅沟通肿瘤的重要手术方法。
Objective: To investigate the clinical characteristics, types, diagnosis and surgical treatment of orbital cranial tumors. Methods: Totally 60 patients with orbital craniofacial tumors confirmed by surgical pathology or follow-up were selected. All patients underwent CT scan and 54 routine MRI scans were performed, of which 42 were enhanced. 2 0 routine optic canal tube X-ray. The pterional approach to remove the tumor in 12 cases, by the amount of tumor removal 21 cases. RESULTS: The most common positive signs were prominence of the eye, increased orbital pressure, and decreased visual acuity. The most common symptom was headache. The more common orbital cranial tumors are meningiomas, fibrous dysplasia and metastases. CT or MRI scan of the orbital cranial tumor and optic nerve hole X-ray have some imaging features. Pathways of orbital cranial communication include optic canal, supraorbital fissure and orbital cranial border bone. Total resection of tumor in 32 cases, subtotal resection of the tumor in 1 case. Conclusion: To master the clinical features and classification of various orbital craniofacial tumors and to improve the diagnostic and differential diagnosis by comprehensively using CT, MRI and X-ray examination. Wing point approach and the amount of approach is an important surgical method of orbital cranial tumor communication.
