title: [Facial bone fracture--statistical analysis and clinical aspects].
abstract: We experienced 102 cases of facial bone fracture during 16 months of 1986 to 1987. These cases were analyzed statistically concerning causes, age and locations of the fracture. These fractures have increased rapidly in number. The causes were classified into three types; occurrence during sport, traffic accident and fighting, which were equal in number. There were 85% males and 15% females in the patient cohort, which were concentrated at the ages of 10-20 years. A large part of the fractures was mostly consisted of maxillo-facial components (95%). These trends were similar to the previous report of our clinic (1972-1979). On the other hand, not only severe dysfunctioning cases but also complicated cases increased in number, so that the several clinical aspects were reported. Case 1: 17-year-old male presented with retraction of left cheek caused by Rugby foot ball, whose malar bone was dislocated backward and anticlockwise, was treated with oroantral reduction and with the intermaxillary packing of silicon blocks. Case 2: 10-year-old boy with complaint of double vision occurred by head blow to right eye. Pure type blowout fracture of the orbital floor was presented, which was reconstructed by silicon plate from the incision of the lower eyelid. Case 3: 59-year-old male presented with 6 month history of diplopia and retraction of left eye ball, had been under the conservative care by an eye doctor. X-ray examination showed the intraorbital soft tissue was blown out into the ethmoidal sinus. However the transethmoidal reduction was performed, the result was not satisfactory.(ABSTRACT TRUNCATED AT 250 WORDS)
