[Frontal sinus barotrauma: about a case and review of the literature]

Sinus barotrauma is the second most frequently reported injury after middle ear barotrauma. The front sinus is the most common site affected. This is a rare and specific pathology. We here report the case of a 26-year-old patient having severe left frontal pain with ipsilateral epistaxis after a dive. CT scan showed left frontal hemosinus. Patient evolution was good after therapy. Frontal sinus barotraumas are accidents related to the variations in environmental pressure. Epistaxis is a sign of serious health condition, CT scanner plays a role in evaluating potential predisposing factors and establishing monitoring procedures. Patient treatment aims to relieve symptoms and to remove predisposing factors. Frontal sinus barotraumas are a rare injury ; orbital and encephalic complications are exceptional. Their treatment coincides with that of their causal pathology.
