Total removal of pineal region tumor

Objective To discuss feasibility and technical outline of total resection of pineal tumor.Methods 70 patients with pineal tumors in our hospital from 1986 to 2000 were analyzed retrospectively.Results Surgical approaches were transventricle in 18 cases, Poppen approach in 35 cases and Krause approach in 17 cases. Pathological diagnosis included 21 gliomas, 14 germ cell tumors, 7 meningiomas, 7 teratomas, 6 epidermoid cysts, 4 gelatine hyperplasias, 3 dermoid cysts, 2 meninges cysts, 2 arachnoid cysts, 1 chordoma, 1 vascular malformation, 1 pituitary adenoma and 1 Galen vessel malformation. Operation procedures consisted of total resection in 49 cases (70%), subtotal resection in 13 cases (18%) and biopsy in 8 cases (11%). The percentages of the three operation procedures were 41(93%),3(7%) and 0(0%) respectively after 1995. Those with tumors totally resected remained well during follow up.Conclusion Surgical removal is effective for pineal tumors, especially for benign tumor. Adequate approach and position, as well as skillful microsurgical technique are the key factors for suceess.
