ABSTRACT

This article outlines the surgical technique and the indications for the lateral transmaxillosphenoidal approach, which is illustrated by an index case. A 27-year-old woman presented with a trigeminal sensory deficit caused by a dermoid tumor occupying the lateral compartment of her right cavernous sinus. A lateral transmaxillosphenoidal approach was performed, and the tumor was removed lateral to the intracavernous carotid artery (ICA) and medial to intracavernous cranial nerves. The lateral transmaxillosphenoidal approach is similar to the transmaxillosphenoidal approach used for the removal of pituitary adenomas invading the medial compartment of the cavernous sinus. By opening the lateral wall of the sphenoid sinus just above and laterally to the carotid artery, tumor can be removed medial to the intracavernous cranial nerves and lateral to the ICA.
