INTRUSION OF AN INCISOR TOOTH INTO THE CONTRALATERAL FRONTAL-SINUS FOLLOWING TRAUMA

Although intrusions of glass fragments into the frontal sinuses are no t uncommon in traffic accidents, a case with a tooth in the frontal si nus has never been reported. We report a patient with traumatic inclus ion of an incisor tooth in the contralateral frontal sinus. Radiograph ic investigations demonstrated the tooth in the frontal sinus though n o skin damage was recognized on the upper face. The usefulness of CT s can in localizing the missing tooth after facial trauma and its route of entry into the contralateral frontal sinus is discussed.
