Extensive Transbasal Approach to Skull Base Tumor
|
|
|
|
|
Abstract
|
|
|
The extensive transbasal approach by Kawakami is a modification of the transbasal approach of Derome. This approach. An en bloc bilateral osteotomy of the orbital roofs and frontal sinus following an ordinary bifrontal craniotomy improves the
exposure
of midline lesions of the anterior and middle skull base, while mimimizing the need for frontal lobe retraction.
The authors present 5 cases operated on via this approach. The tumor diagnosis of 5 cases was 3 cases of tuberculum sellae meningioma. 1 case of astrocytoma and 1 case of craniopharyngioma. In two patients (cases with localized lesions in the
midline).
The extensive transbasal approach was used alone, in the remaining three (cases with far lateral extension to the temporal base), it was combined with other skull base approachs. Our experience in 5 cases and the advantage of this approach are
described.
