ABSTRACT: Orbit is a conical cavity in which the base lies anteriorly and the apex directed at Optic Foramen .By Age of 5 years orbital growth is 85% complete, finalized between 7 years of age. Orbit is formed from 7 bones (Maxillary, Zygomatic, Frontal, Ethmoid, Larimal, Palatine, and Sphenoid ). It consists of Four Walls – roof, lateral, medial, floor .Medial wall and floor are thin ,While Lateral wall and Roof are Stronger. Floor of orbit is weakened due to infraorbtal Canal passing through it. In Pure blowout fracture one orbit wall is affected, without involving orbital rims. The inferior and medial walls are affected most frequently. Clinical features are diplopia, infraorbital nerve paresthesia , entrapment of soft tissue within the maxillary sinus, restriction of ocular movements and enophthalmos. CT scan is most helpful method for diagnosis of orbital fracture. For orbit reconstruction, natural and synthetic materials are available. We report a case of 21 years old man, diagnosed with orbital floor fracture after slip and fall from his two wheeler The surgical treatment involved orbital floor reconstruction with titanium mesh under general anesthesia. The outcome was satisfactory and during followup visual disturbances or paresthesia was not present.
