Abstract:
OBJECTIVE To study anatomical features of the cavernous segment of the internal carotid artery(ICA)via the extended transsphenoid approach under endoscope.METHODS Extended transsphenoid approach was performed on 11 adult cadaver heads.The appearance features of the cavernous segment of the ICA and its vessel branches were observed under endoscope.RESULTS The cavernous segment of the ICA can be divided into 5 segments and has 3 vessel branches.The optico-carotid recess is the landmark to define the ICA and optic nerve during operation.The optico-carotid recess is located between internal carotid and optic prominences,all of them are located on the lateral wall of the sphenoid sinus.CONCLUSION The cavernous segment of the ICA is the most important anatomic structure via the extended transsphenoid approach.The cavernous segment of the ICA,branch vessels,and important nerve tissue structures can be clearly visualized under endoscope via the extended transsphenoid approach.An extended transsphenoid approach with the help of an endoscope is an optimal surgical approach for the lesions that invade the internal wall of cavernous sinus.
