BACKGROUND: For @entity1804 , the fronto-basal exposure is considered the standard approach. The superior interhemispheric (IH) approach is less described in the literature. OBJECTIVE: To assess the surgical complications, functional outcome (visual, olfaction), morbidity and mortality rates and late recurrence, after resection by superior IH approach of midline @entity1297 . METHODS: Between 1998 and 2008, 52 consecutive @entity1 with midline @entity1653 on the anterior portion of the skull base (mean age: 63.8    13.1; sex ratio F/M: 3.7) were operated on via the superior IH approach. After a mean follow-up of 56.9    32.9 months, an independent neurosurgeon proposed a prospective examination of functional outcome to each @entity1 , as well as a visual and olfactory function assessment. RESULTS: Fifty-two @entity1 were divided into a group with @entity1653 (n=34) and another with @entity1653 (n=18). The outcome was characterized by @entity260 in 13 @entity1 (25%), mortality rate in two (3.8%) and long-term morbidity at in 17 (37%) of 50 surviving @entity1 . Based on multivariate analysis, no prognosis factor was significant as regards the favorable outcome. The mean postoperative KPS score (86.6    9.4) was significantly improved. However, @entity751 was observed in four @entity1 (8%), @entity9905 -anosmia in 34 (68%) and visual acuity deteriorated in one (2%). CONCLUSION: The superior IH approach could be considered a safe anteriorly orientated midline approach for removal OGM and TSM @entity1653 .
