Dear Editor,
Blow-out fracture is characterized by a damage to the orbital walls with intact orbital margins and bone fragments displaced outside the orbit. The common mechanism of injury for a orbital fracture is blunt trauma to the orbit or forehead.[1] A 32-years-old man was brought to our emergency department with a swollen condition on his right orbita which began after sneezing. He had horizontal diplopia and crepitus as a sign of periorbital emphysema. Computed tomography scan revealed blow-out fracture on the medial wall of right orbita image, extra conala dipose tissue protruded partially to the superior oblique muscle and free air inside the soft tissue areas [Figures 1 and 2].

Clinical symptoms of orbital fracture are diplopia, enophthalmos, or restriction of gaze.[2] Orbital emphysema without impaired vision is not a life-threatening condition and usually resolves spontaneously within 2 weeks. Cases of spontaneous orbital emphysema caused by sneezing, cough, or nose blowing are very rare.
