Figure 4
(a) Preoperative image of planned right eyebrow incision and (b) six-week postoperative image in the same patient. (c) Illustration of supraorbital craniotomy through an eyebrow incision. The incision is within the eyebrow (white), lateral to the supraorbital nerve (S) and frontal sinus (FS). The temporalis (T) is separated just posterior to the zygomatic process for the burr hole. Bone flap is approximately 1.5 × 2 cm (B). (d) Illustration after opening demonstrating dural opening (D), retracted frontal lobe (FL). The orbicularis oculi muscle (M) is reflected inferiorly with the pericranium.
