A 26-year-old hyperbaric oxygen therapy technician with a history of chronic paranasal sinusitis was admitted to the emergency department because of ecchymosis and painful swelling over her lower right eyelid. As part of her job, she accompanied patients into the treatment chamber. She reported having worked when she had a cold 3 days before presenting to the emergency department. During decompression to 2.5 atmospheres, she felt discomfort under her right eye. Sudden, painful swelling and ecchymosis developed under her eye when the pressure was reduced to about 1.6 atmospheres (Figure 1). A computer tomography scan of the head in coronal view showed a fracture of her maxillary bone (Figure 2). She recovered uneventfully with supportive treatment.
