Endoscopic Endonasal Approach of Blow Out Fracture Reduction- A Novel Technique

Blunt trauma to orbit can lead to orbital blow out fracture. Computerized tomography of paranasal sinuses plays the main role in diagnosing it. Repairing the defect and restoring the orbital contents is a challenging task for the surgeon. Endoscopic endonasal approach in reduction of blow out fracture provides good cosmetic outcomes and grossly minimize surgical complications. We report a case of 18-year-old male presented with diplopia, restriction of eye movements and enophthalmos due to Road traffic accident. CT paranasal sinuses showed right side floor, medial orbital wall fracture with medial rectus muscle entrapment. We planned endoscopic endonasal approach to reduce the fracture and multilayered repair done using bone resected from choncha bullosa, fat and fascia lata. Patient relieved of symptoms post operatively without any complications.
