AbstractForeign bodies can present a diagnostic challenge to the maxillofacial surgeon. Three patients, who suffered from a penetrating injury with a wooden foreign body, were examined and treated. Their preoperative CT and MRI scans were evaluated. In an acute case, the penetrating wooden body mimicked air bubbles. In the other two patients, the wood was retained for several months and appeared with a much higher density on CT. In MRI the wooden foreign bodies gave a low signal intensity. In all injuries removal of the foreign body was delayed, because it was initially radiologically missed or misdiagnosed. In the appropriate trauma setting a penetrating wooden body must always be considered. Its attenuation value increases with time as water is absorbed from the surrounding tissues. Although the radiological appearance may show a great variety, CT imaging is the basic diagnostic technique. MRI is the method of second choice.
