The Supraorbital Approach to a Large Retrobulbar Cavernous Hemangioma of the Orbit-One Case Report

Purpose: To report a complete excision of a large superior orbital retrobulbar cavernous hemangioma using supraorbital craniotomy through the suprabrow approach combined with superior orbital wall removal. Case summary: A 31-year-old woman presented to our clinic with left exophthalmos beginning one month earlier. Visual acuities and intraocular pressures of both eyes were normal and there was no diplopia and no limitation in ocular movement. On exophthalmometry, the right eye was 15 mm and the left eye was 18 mm. CT and MRI demonstrated a superior orbital retrobulbar mass of 2.0×2.6×2.0 cm in size, and the mass displaced the superior rectus and levator palpebrae muscles. After six months, a neurosurgeon attempted a classic supraorbital craniotomy but failed. Fourteen months later, the authors completely excised the tumor through superior orbital wall removal. The tumor was confirmed as a cavernous hemangioma after histopathologic study. Conclusions: The authors succeeded in complete excision of a superior orbital retrobulbar cavernous hemangioma using supraorbital craniotomy through a suprabrow approach combined with superior orbital wall removal.
