Resection of an orbital tumor with coronal incision and frontal sinus fenestration

A case of orbital tumor is reported. A 52-year-old man consulted our hospital with left exopthalmus and impaired vision. On opthalmologic exmination, left exopthalmos in Hertel statometer, left impaired visual acuity and degeneration of retina in superolateral region of the optic disk of his left eye were noted. Magnetic resonance imaging (MRI) demonstrated a tumor with clear margin in the retro bulbar space. He was referred to our oto-rhino- laryngological section for surgery. At surgery, coronal incision was made and the extended lateral orbitotomy was made with fenestration of the frontal sinus. The tumor was easily removed without any complication on visual acuity and eye-ocular movement. We conclude that the approach with coronal incision and frontal sinus fenestration is useful for resection of orbital tumor.
