A malleable brain retractor may be placed against the dura to protect against unintentional durotomy. The outer table is left intact to maintain cosmesis. Bone dust is washed out with antibiotic irrigation prior to dural opening. The dura is opened in a ��C��-shaped http://www.selleckchem.com/products/Imatinib(STI571).html fashion and reflected inferiorly with a stitch. The microscope is brought into the field, the frontal lobe is lightly retracted with a cottonoid, and the CSF cisterns are opened to allow CSF egress to facilitate brain relaxation. Following brain relaxation, the primary procedure may be performed safely with no fixed retractors on the brain and with use of the operative microscope, a rigid rod-lens endoscope, or both. Wound closure is straightforward. The dural leaflets are reapproximated with a 4-0 Nurolon suture sewn in a running fashion.

The craniotomy bone flap is replaced with a titanium burr hole cover and two titanium square plates to improve the cosmetic result by restoring the supraorbital ridge. The pericranium and muscle flap are then closed primarily. Buried, interrupted, and absorbable sutures are used in the dermis, and a 5-0 prolene subcuticular stitch is placed without any knots to ensure removal in the office in 7�C10 days. A head wrap can be applied until the first postoperative day to lessen subgaleal edema formation. 3. Case Illustrations A number of case series utilizing this approach have been published in the literature (Table 1). The reported morbidity and mortality in these series are similar to that reported in surgeries on similar pathologies by other approaches.

It is important to understand the benefits and shortcomings of this approach so that case selection can be performed appropriately. We have provided a few case examples from our own series to highlight some of the benefits of this approach, as well as ways to make the approach safer and more efficacious using modern techniques, technology, and adaptation. Table 1 Case series of keyhole supraorbital subfrontal approaches through an eyebrow incision. 3.1. Case1 A 71-year-old RH woman presents with a history of progressive headaches who underwent an MRI of the brain with gadolinium contrast administration. The MRI demonstrated a homogeneously enhancing sellar/suprasellar lesion that extended to the planum sphenoidale causing optic chiasmal compression as well as compression of the right optic nerve.

The right A2 branch of the anterior cerebral artery coursed through the superior aspect of the tumor. Its imaging characteristics were most consistent with a tuberculum sellae meningioma. This increased in size on subsequent imaging, and the patient underwent elective resection of her tumor by a right supraorbital keyhole craniotomy through the right eyebrow. Preoperative and postoperative imaging are shown (Figure 1). She had a gross total resection of a WHO grade I Anacetrapib meningioma and had no visual deficits postoperatively.
