Supraciliary keyhole craniotomy for anterior frontal lesions in children

Treatment for anterior frontal space occupying lesions such as epidural hematoma, vascular malformations or brain tumors, have typically involved invasive craniotomies. This method often requires large incisions with wide exposure and may be associated with high morbidity rates. The basis for the "keyhole" method is that a minimally invasive craniotomy is often sufficient for exposing large areas deep in tissue, and may limit exposure and decrease surgically related morbidity while enabling adequate removal and decompression. The supraciliary method includes a cut above the eyebrow and a small craniotomy to uncover the base of the frontal lobe and the orbital roof. We demonstrate our experience with this method. We identified children who were operated via the supraciliary approach between January 2009 and December 2013, and gathered their pre- and post-operative clinical and radiological statistics. Fourteen patients were identified. Pathologies included tumors, abscesses and epidural hematomas. Nine were operated due to epidural hematoma, two due to tumors, two due to brain abscesses, and one for anterior encephalocele. No significant peri-operative or post-operative complications were observed. Long-term follow-up shows that the surgical scars were nearly invisible. The supraciliary approach is a safe, effective and elegant technique for treating lesions in the anterior skull base. The method should be weighed alongside traditional methods on a case-by-case basis. (C) 2015 Elsevier Ltd. All rights reserved.
