Sammanfattning
In this case we report how a previously healthy 35-year-old man developed a spontaneous monosymptomatic facial emphysema. The emphysema was found in large parts of deep and superficial compartments of the facial muscles, intraorbital to the optical nerve and along the blood vessels to the larynx level. The reason for this was never determined, but the differential diagnostics includes allergic reaction, oesophagus/larynx rupture, infection, fracture of the facial bones, trauma or self-inflicted damage. The patient's symptoms receded over a course of four days to complete recovery.
