Direct approaches to vascular lesions in the cavernous sinus via the medial triangle
Vascular lesions in the cavernous sinus were radically operated on under normal body temperature in a semi-sitting position which reduced pressure in the sinus. In this series of 17 cases of various kinds of vascular lesions in the cavernous sinus, the approach leads by a fronto-latero-basal craniotomy to the superior and lateral walls of the cavernous sinus. Via an ispilateral approach, the medial triangle in the superior wall was opened for repair of the vascular lesions of the C 3 and C 4 portions of the internal carotid artery, and Parkinson’s triangle in the lateral wall was opened for lesions of the C 5 portion. Via a contralateral approach, the medial side of the medial triangle was opened for clipping of the aneurysm originating from the medial wall of the C 3 portion. Both the ipsilateral and the contralateral approaches to the vascular lesions in the cavernous sinus are presented in this paper.
