One hundred and one cases with facial bone fractures admitted to the Department of Otolaryngology of Seoul National University from September, 1983, to September, 1988, were statistically analysed in age incidence, sex distribution, causes, anatomical locations, paranasal sinus involvement, associated injuries and managements. The following results were obtained. 1) The age incidence was the highest in third decade(31%) and 80 patients(79%) were in male and 21 patients(21%) were in female. 2) The most common cause of facial injuries was intended violence. 3) Anatomical locations of facial injuries were, in order of frequencies, mandible(34%), nasal bone(22%), zygomatic complex(14%) and maxilla bone(10%). 4) Mandible fractures was the most common facial fracture. Simple fracture occurred in 64% and comminuted fracture occurred in 23%. 5) In maxilla fractures, LeFort type I and type II occurred in 39% respectively. 6) In orbit and zygoma complex fractures, the blow-out fracture occurred in 31%, and the tripod fracture occurred in 36%. 7) The frequency of facial bone fracture involving the paranasal sinuses was in 60%. The maxillary sinus was the most common(34%). The ethmoid and frontal sinuses were involved in 22% and 5% respectively. 8) Most cases except nasal bone fractures were treated by open reduction and internal fixation.
