Clinical feature and microsurgical treatment of cranio-orbital tumor

Objective To study the clinical feature and microsurgical treatment of tumors involving the cranio-orbital region.Methods In 102 cases who had been diagnosed by clinical manifestations and neuroradiological features,different approaches of operation were used,and according to the results of frozen biopsy in operation,microsurgical techniques were used to resect the tumors.Sixty-seven cases had their tumor located in anterior cranial fossa-orbit,26 in middle cranial fossa-orbit and 9 in anterior and middle cranial fossa-orbit.Ninty-one cases(89.2%) showed malfunction of optic organs.Sixty-two cases(60.8%) had symptoms of intracranial hypertension.Results Eighty-one cases received total removal and others subtotal resection of tumors.No postoperative death occured.Ninety-three patients were followed up for 6 months to 14 years with a mean of 5.6 years.Of them,70(75.3%)recovered satisfactorily,7(7.5%)suffered recurrence and 16(17.2%)had different degrees of sequela.Conclusions One of the most common manifestations of cranio-orbital tumor is disorders of optic organs.The microsurgical technique,with different operative approaches and directed by frozen biopsy in operation can result in good prognosis for these patients.The injury to optic nerve could be reduced by using F-VEP monitor in operation.
