Case report. Periorbital pneumatocele after facial trauma in a boxer.

On examination he had an obvious fracture of the nose with evidence of epistaxis and slight deviation of the nose to the right, together with surgical emphysema between the nose and the eyelids on the right. He took great delight in producing the deformity for the amusement of his comrades. Finger pressure applied to the swollen tissues caused deflation and an audible hiss of air escaping into the nose. Neurological examination was normal and there was no diplopia. Neurological observations for 24 hours were entirely normal. Radiological examination confirmed the presence of a fracture of the nasal bone, but no fracture of the orbit was demonstrated.
