[Diagnosis and management of tumors with orbito-cranial access]

To identify the characteristics and extent of orbitocranial tumor for the selection of operative methods, 64 patients with the tumor were studied with clinical materials, primarily CT and magnetic resonance imaging (MRI) appearances. The lesions were found in the orbit, cranium and orbito-cranium boundary parts and their diagnoses in regard to localization and identification could be made. Based on the preoperative diagnosis of an orbito-cranial tumor, its location, character, secondary changes and operation(s) in the past, a surgical approach was designed. The resection of a tumor could be completed in once or in several times of operation. 64 operations were performed on 53 patients and other therapies were given to the other 11 patients. The operative methods included orbitotomy via anterior route, 21 times via lateral route and 30 times via transcranial route. The operative results suggest that the transcranial route be complicated and have more complications; preoperatively, the operative indication be strictly selected and intraoperatively, ophthalmologists closely cooperate with neurological surgeons.
