Facial Trauma is common. The emergency physician should conduct a thorough examination of the oral tissues. A laceration in the palate can be easily missed and should be elicited. Failure to identify a split palate can result in severe dentofacial deformity.

Guerin's sign is bruising in the palate in the region of the greater palatine arteries. We present a patient who sustained blunt facial trauma and as a result had a mobile maxilla and a severe malocclusion. An associated laceration in the palate pointed to a split palate confirmed on CT. This is a reminder to clinicians, especially those working in acute medicine to conduct thorough examination of the oral tissues. A laceration in the palate can be easily missed and should be looked for as part of a systematic examination. Intraoperative management may change depending on the fracture pattern and displacement.
