Abstract
Background
To repair a blow-out fracture, the endonasal approach is indicated when the center of the fracture occurs in the orbital floor medial to the infraorbital nerve, or when the orbital tissue is herniated inwards; additionally, the combined endonasal and transmaxillary approach is indicated for fractures of the anterior and lateral parts of the orbital floor.
Method and conclusion
The use of endoscopic modified medial maxillectomy and special instruments enabled the surgeon to repair an outwardly herniated blow-out fracture by the endonasal approach alone, despite the center of the fracture being in the orbital floor lateral to the infraorbital nerve.
