The supraorbital keyhole approach via an eyebrow incision for resection of tumors around the sella and the anterior skull base.
OBJECTIVE
This study evaluates the technique, indications, advantages and limitations of the minimal invasive supraorbital keyhole approach via an eyebrow skin incision for resection of tumors around the sella and the anterior skull base.


RESULTS
In 9 patients (5 males, 4 females) different tumors (6 meningiomas, 1 craniopharyngioma, 1 Rathke's cleft cyst and 1 hypophysitis) with a maximum diameter of 30 millimeters were resected via a small eyebrow incision and a supraorbital keyhole craniotomy. Details of the operative procedure include the use of a high-speed drill, a microsaw, bayonet-shaped instruments, careful microsurgical dissection, the use of a neuroendoscope and miniplates for closure. In all patients complete tumor removal was achieved. Mean duration of surgery was 01 h 51 min and mean hospital stay was 8.9 days. There were no significant postoperative complications. Clinical examination and MR imaging after a mean follow-up of 313 days revealed no tumor recurrence and a very satisfying overall functional and cosmetic result in all patients.


CONCLUSIONS
The eyebrow incision supraorbital keyhole approach proved to be safe, effective and time-sparing. The authors recommend this approach for resection of small tumors around the sella and the anterior skull base in selected cases as a valuable alternative to standard skull base approaches.
