THE CLINICOSTATISTICAL STUDY OF FACIAL BONE FRACTURE IN RECENT FIVE YEARS

ABSTRACT

This study was aimed to furnish the data of facial bone fracture which was related regional and social environment and to aid diagnosis and treatment of the fracture. This is the retrospective and clinicostatical study on 625 patients with facial bone fracture. The patients were treated in the Dept. of Oral and Maxillofacial Surgery of Wonkwang University Hospital from Jan. 1, 1993 to Dec. 31, 1997. The result were as follows The facial bone fractures occured most frequently in the twenties(32.3%) and male were predominent(77.4%) than female. The most frequent etiologic factor of facial bone fracture was fall down(42.8%) and midface fracture was traffic accident(63.4%). The most common site of fracture was symphysis(51.1%) and angle(29.7%), condyle(27.5%), ZMC(13.4%) were next in order of frequency. Of the 626 patients, 590 patients(89.5%) were treated with open reduction and only 36 patients(10.5%) were treated with closed reduction. In the blow, the ratio of angle fracture(50%) is especially high(the overall ratio 29.7%) and in the Out car TA, the ratio of ZMC fracture(34.6%) is especially high(the overall ratio 13.4%). In the fall-down, the ratio of symphysis(58.4%) and condyle fracture(33.6%) is especially high(the overall ratio 51.1%, 27.5%). Postoperatives complication were found in 35(5.6%) of 626 patients, in which mouth opening limitation(3%) was the most common. Above results suggest that early diagnosis and treatment of fracture site, systemic condition and associated injuries are nessary, and cooperative treatment with medical department should be performed.
