METHODS: We performed a retrospective analysis of a series of 37 cases involving patients who underwent transcranial surgery through pterional approach for treatment of cranio-orbital tumors in our department in the past 8 years. Pterion approach craniotomy was performed to all patients. After removing tumors in the skull by the neurosurgeon, ophthalmologist removed tumors in orbit. We took measures below to decrease complications, including grounding optic canal through an abrasive drilling when necessary, hanging various extraocular muscles to be exposed for protection, refrigerating by refrigeration heads to remove tumors, at last sewing up orbit septum after surgery. RESULTS: Tumors were removed completely in 32 cases, and incomplete in 5 cases due to extensive invasion into the cavernous sinus or sphenoid sinus. Of all the cases, benign tumors were demonstrated in 28 cases (75.6%, 28/37) and malignant in 9 (24.3%, 9/37). The most common lesion type was meningioma in 11 cases (29.7%, 11/37). Extraocular muscles (EOM) impairment, occurring in 21 cases (56.7%, 21/37), was the most frequent postoperative complication. The most serious consequence was vision loss occurred in 4 cases (10.8%, 4/37). Other complications, such as 11 cases of transient blepharoptosis 29.7% (11/37), 5 cases of mydriasis in 13.5% (5/7); 2 cases of cerebrospinal rhinorrhea in 5.4% (2/37). CONCLUSION: Cranio-orbital tumors can be removed completely using transcranial approach, and the pterional approach offers excellent exposure. Cooperation of interdisciplinary team of neurosurgeons and ophthalmologists conduces to full use of respective professional advantages. The experience of ophthalmic operation technology can decrease occurrence of ocular complications after surgery.展开更多
