چکیده انگلیسی


• We introduce a method to treat cavernous sinus cavernous hemangioma (CSCH), a purely extradural approach.
• 12 patients were operated through the purely extradural approach, and all patients received a complete tumor resection.
• Adverse events and complications, intraoperative and postoperative, and morbility were acceptable.
• No patients experienced the tumor recurrence.

ObjectiveCavernous sinus cavernous hemangioma (CSCH) is a rare extra-axial vascular lesion and is difficult to be removed due to their location, propensity for profuse bleeding during surgery, and relationship to complex neurovascular structures. The purpose of this study is to report our experience of the removal of CSCHs through a completely extradural transcavernous approach.MethodsTwelve patients with CSCH, who were operated through a purely extradural approach, were retrospectively studied. Clinical symptoms and signs, radiographic characteristics, operative techniques and outcomes of these patients were analyzed.ResultsHeadache and visual impairment were the most common clinical symptoms, followed by facial hypesthesia and ptosis. Radiographically, CSCHs have a characteristic pattern. On computed tomography (CT) scans, CSCHs are isodense or minimally hyperdense, with an intense homogenous contrast administration. Magnetic resonance image (MRI) scans revealed well-demarcated and hypo- to isointense lesions on T1-weighted images and characteristically, markedly hyperintense lesions on T2-weighted images. The T2-weighted images showed a marked homogeneous and an intense enhancement after contrast administration. All CSCHs were treated by a completely extradural transcavernous approach. Gross total excision was achieved in all 12 patients. Post-operative complication included transient cranial nerve dysfunction for 2–3 months in eight patients, and three patients developed a permanent VI nerve palsy. The follow-up period ranged from 4 to 117 months (mean 62 months), and no patient had experienced tumor recurrence.ConclusionCSCHs are rare and challenging skull base tumors. The microsurgical resection, using an extradural transcavernous approach which allows complete tumor resection with an acceptable intraoperative and postoperative complications, should be considered as a favorable choice among all treatments.
