Abstract
Surgery for tuberculum meningiomas is still challenging to obtain good functional outcomes. There are various surgical approaches advocated, because each approach has both advantages and disadvantages. We retrospectively analyzed the consecutive 35 cases of tuberculum sellae meningiomas that were mainly operated via modified frontobasal interhemispheric approach (IHA) during the last 7 years. Complete tumor resection was achieved in all but 3 cases with severe adhesion to the neural tissue. Out of 26 cases with preoperative visual impairment, 24 cases (92%) showed functional improvement. Postoperative anosmia was seen in 3 cases (12%) out of 27 IHA procedures. Our operative procedures are described in detail, and crucial points, including the strategy and the important operative techniques, are discussed.
