Sphenoid sinus barotrauma after scuba diving.

We report the case of an 18-year-old male patient operated on for sphenoid sinus barotrauma after scuba diving. The patient attended our emergency department because of intractable headache but did not improve with conservative treatment. After computed tomography and magnetic resonance imaging examination, he was diagnosed with sphenoid sinusitis that extended to the nasal septum. He therefore underwent surgery for sinus ventilation and abscess drainage.
