[Traumatic subcutaneous emphysema of the face: the hazard of holding a sneeze].

In this period of pandemic, protective measures and social distancing, sneezing might not be well received and trying to suppress a sneeze is tempting. It's not always a good idea. We here report the case of a patient suffering from minor facial trauma. The next day after the accident, while trying to hold back a sneeze, the patient caused sudden swelling of the right cheek, associated with subcutaneous emphysema and disturbances in sensitivity, revealing an unrecognized fracture of the right maxillary sinus. Post-traumatic subcutaneous emphysema of the face, caused by suppressed sneezing, is rarely described.
