case_images: A meningioma at the sphenoidal level was observed at the CT scan and the MR was partially calcified, with associated bifrontal vasogenic edema (Figure 1A). The bone flap was fixated using two Cranial LOOP  L at the lateral basal level close to the pterion and two regular-size Cranial LOOP  at the posterior frontal level (Figure 1E). CT scans were performed immediately after surgery (Figure 1B) and at a five-month follow-up visit (Figures 1C-1D), showing correct positioning of the bone flap without settling or artifacts.

(C) Seven-month post-operative CT scan image: sagittal reconstruction view of the bone. (D) Seven-month post-operative CT scan image: coronal reconstruction view of the bone. (E) Surgical view after microsurgical clipping and fixation of the bone flap with Cranial LOOP .

case_images: Later on, the patient had a manifest aneurysmal recanalization (Figure 2A). The bone flap was fixated using two Cranial LOOP  L at the basal lateral level close to the pterion and two regular-size Cranial LOOP  at the posterior frontal level (Figure 2E). CT scans were performed immediately after surgery (Figure 2B) and at a seven-month follow-up visit (Figures 2C-2D), showing correct positioning of the bone flap without settling or artifacts.

(C) Four-month post-operative CT scan image: sagittal reconstruction view of the bone. (D) Four-month post-operative CT scan image: coronal reconstruction view of the bone. (E) Surgical view after tumor resection and fixation of the bone flap with Cranial LOOP .

case_images: However, further study revealed a 5-cm meningioma on the olfactory groove with edema around the lesion (Figure 3A). The cranial flap was fixated with two Cranial LOOP  L at the basal lateral level close to the pterion and two Cranial LOOP  XL at the posterior frontal level, covering the burr holes performed on both sides of the superior longitudinal sinus (Figure 3E). CT scans were performed immediately after surgery (Figure 3B) and at a four-month follow-up visit (Figures 3C-3D), showing correct positioning of the bone flap without settling or artifacts.
