Endoscopic orbital transposition for inverted papilloma in an unusually large supra orbital ethmoidal cell

The management of inverted papilloma involving frontal sinus and supraorbital ethmoidal cells is still challenging even for the well-trained rhinologists. These cases sometimes require an external approach, but now with the technique of endoscopic orbital transposition many such cases are handled effectively endonasally. Here in our case report, we are describing an unusually large supraorbital ethmoidal cell, which has pneumatized all the way above the orbit, from the frontal sinus to the anterior clinoid process and hence with the optic nerve lying inside this cell. We will be describing how we still could tackle this endoscopically with the modified endoscopic Lothrop and orbital transposition.
