Evaluate the integrity of the medial canthal tendon (MCT) by placing the thumb and index finger over the nasal root and carefully applying lateral tension to each lower lid. Healthcare providers can usually categorize a bone fracture based on its features. The classic fracture pattern involves lateral nasal bones, inferior orbital rim, medial orbit/ethmoid wall, nasal maxillary buttress at the piriform aperture, and the junction of the frontal process of the maxilla with the frontal bone. The nasal bone fractures were exposed para-nasally through intra-oral incisions and fixed with two titanium plates with 4 mm screws.
