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 causesage and locations of the fracture. These fractures have increased rapidly in number. The causes were classified into three types; occurrence during sporttraffic accident and fightingwhich were equal in number. There were 85% males and 15% females in the patient cohortwhich 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 handnot only severe dysfunctioning cases but also complicated cases increased in numberso that the several clinical aspects were reported. Case 1 : 17-year-old male presented with retraction of left cheek caused by Rugby foot ballwhose maler bone was dislocated backward and anticlockwisewas treated with oroantral reduction and with the intermaxillary packing of silicon blocks. Case 2 : 10-year-old boy with complaint of double vision occured by head blow to right eye. Pure type blowout fracture of the orbital floor was presentedwhich 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 ballhad been under the conservative care by an eye doctor. X-ray examination showed the intraorbital soft tissue was blown out into the ethomoidal sinus. However the transethomoidal reduction was performedthe result was not satisfactory. Case 4 : 17-year-old female visited emergently with facial destruction by traffic accident. Bilateral mid-third fracture of the face and fractures of the mandibullar processes were found. In order to pull out the maxillasilicon blocks were packed into the maxillary sinus and intermaxillary fixation with bite plate was tried. Howeverthe maxilla was receded backward and “dish face” deformity was appeared. © 1989, The Oto-Rhino-Laryngological Society of Japan, Inc. All rights reserved.
