Intracranial schwannomas predominantly arise from the 8th cranial nerve, and less commonly from the 5th, 9th, 10th, and 7th cranial nerves. Herein, we describe the clinical features and surgical management of orbital schwannomas. A 64-year-old woman and 45-year-old woman were admitted to our hospital with complaints of proptosis. In particular, visual field defects and decreased visual acuity were demonstrated in the 64-year-old patient. A CT scan showed low density lesions within the orbital canal. MR imaging revealed a low signal intensity on the T1-weighted scan, and a high signal intensity on the T2-weighted scan with heterogenous enhancement. The tumors were totally resected via an orbitocranial approach. The histopathological finding was neurilemmoma. It was found in one patient that the tumor originated from the lacrimal nerve. In the other patient, the tumor originated from the frontal branch of the trigeminal nerve. There was minimal sensory change in the periorbital area in the case of the schwannoma which originated from the trigeminal nerve and a visual field defect remained in the case of the patient with the lacrimal schwannoma. Even though schwannomas have been reported to originate from all cranial nerves, except the optic nerve, most arise from the vestibular nerve. We reported two cases of orbital schwannoma which originated from the lacrimal nerve and the frontal branch of the trigeminal nerve, respectively.

Objectives Surgical management of medial sphenoid ridge meningioma is challenging due to their intimate relationship with anterior visual pathway, cavernous sinus, and arteries of anterior circulation. We analyzed extent of resection and recurrence rate of medial sphenoid ridge meningiomas and discuss the usefulness of preoperative cerebral angiogram in determining preservation of large drainage vein. Methods Between 1995 and 2010, 38 cases of medial sphenoid ridge meningioma underwent surgical resection. Preoperative cerebral angiogram was performed in 29 patients (76.3%) and evaluated the patency of superficial middle cerebral vein and collateral circulation. Results Total resection was achieved in 27 patients (71.1%). Recurrence was observed in 3 patients (11.1%). Regrowth was observed in 4 (36.4%) of the 11 patients with subtotal resection. Two patients of sphenoid ridge meningioma with interdural cavernous sinus extension were successfully removed. Superficial middle cerebral vein was sacrificed in 1 patient. There was no surgical mortality and symptomatic cerebral infarction. Conclusions Sphenoid ridge meningioma with interdural cavernous sinus extension can be removed safely without cranial nerve deficit compared to the meningioma with intracavernous sinus extension. The patency of superficial middle cerebral vein and development of collateral vessel were helpful to determine intraoperative preservation of large drainage vein.

Objectives: Surgery with complete excision is the best avenue for obliteration of hemangioblastoma. However, in brainstem hemangioblastoma, surgical risks make difficult for exact planning of a surgical strategy. The purpose of this study was to review our experience for hemangioblastoma on cervicomedullary junction with regard to clinical and surgical features. Material and Methods: Seven hemangioblastomas in 6 consecutive patients underwent surgical resection in our department between January 2005 and May 2010. Preoperative and postoperative functional outcomes and operative findings were retrospectively reviewed. Results: The studied patients consisted of 2 men and 4 women aged from 19 to 55 years (mean, 32 years). The most presenting symptoms were headache, followed by deterioration of mental status, hemiparesis and dizziness. Von-Hippel Lindau disease was confirmed in 3 case. Preoperative embolization was performed in 2 cases. All of the targeted lesions were totally resected via midline suboccipital craniotomy and well-demarcated surgical plane from the brainstem. Complications included aspiration pneumonia (2 cases), transient aggravation of hemiparesis and unpredicted pneumothorax (each one cases). There was no permanent neurological deficit except 1 case, consecutively performed surgical removal for huge thoracic hemangioblastoma. In two cases, gamma knife radiosurgery should be performed for remaining cerebellar tumors. Conclusions: The hemangioblastoma on cervicomedullary junction can be successfully removed with an acceptable level of risk. In selected cases, preoperative emblolization can be helpful in reducing the possibility of intraoperative disasters.

정중선 전두개저수막종에 대한 전두엽하 겸상막후각신경로 접근법

Anterior skull base meningiomas (ASMs) such as planum sphenoidale meningioma (PSM) and olfactory groove meningioma (OGM) may be symmetric around the midline. Bifrontal frontobasal approach and its variations have long been recommended as standard approach to remove these tumors. In the present report, we describe a subfrontal Falco-olfactory approach to treat these ASMs. The subfrontal Falco-olfactory approach was used to treat nine patients with anterior skull base tumor, including six patients who were diagnosed as PSM and three patients with OGM. Subfrontal craniotomy was performed with minimal dissection of temporalis muscle. In all nine cases, ipsilateral olfactory nerve and tumor base could be visualized in the initial stage of the procedure after retraction of frontal lobe carefully. This allowed for olfactory nerve preservation and early tumors devascularization. Between falx and olfactory nerve (above olfactory nerve), we gained excellent visualization of the tumor. After removal of ipsilateral side tumor, incision of the falx, other side tumor could be exposed easily. Preservation of other side olfactory nerve was also done. All patients had no postoperative complications. Thus, subfrontal transfalcial olfactory approach could be considered as a safe and versatile surgical route for ASMs.
