Resection of sellar area tumor via transeyebrow keyhole approach: anatomic and clinical study

Objective: To evaluate the possibility and gain surgical experiences of the operation of sellar area tumor via eyebrow incision and keyhole approach. Methods: 15 human adult skulls and 5 formalin-fixed human cadaver heads were used to do measurements related to transeyebrow keyhole approach and to imitate the procedure of operation. Clinical operations were carried out on 32 patients with sellar area tumors. Results: Skull measurement demonstrated that the position of supraorbital foramen and frontal sinus would affect transeyebrow keyhole craniotomy. 4 spaces of sellar area could be viewed and controlled under microscope and endoscope. 32 patients operated via this approach got good results. Total resections were gained in 17 patients (53.12%). No approach-related complication was observed. Conclusion: Removal of the sellar area tumors via transeyebrow keyhole approach is absolutely practicable. It is as effective as traditional subfrontal or pterional approach, but with less trauma to the patients.
