Abstract
The anterior cranial base and the suprasellar and parasellar regions approach and its several methods have been described since 1981 by Suzuki et al. [3, 14, 15]. Extended frontal approaches, however, necessitate removal of the crista galli and sectioning of the olfactory rootlets with the associated risk of anosmia, cerebrospinal fluid (CSF) leak, and the need for complex reconstruction of the frontal floor [11, 12]. Bifrontal craniotomy is the conventional approach to lesions in these locations [10, 11], but its shortcoming has been the damage to the olfactory tract [7].
