Medial orbitotomy without opening the ethmoid sinus enables wide exposure and safe removal of an orbital tumour located posterosuperomedially.

Tumours in the posterosuperomedial orbital space are hard to remove because of their site. However, medial orbitotomy without opening the ethmoid sinus produces a wide enough view and a direct route without complications. Posterosuperomedial orbital tumours can therefore be safely, accurately, and easily removed.
