A CLINICAL STUDY OF ZYGOMATIC FRACTURES

This study was undertaken to survey 95 patients with zygomatic fractures who were admitted to Fatima Hospital and the department of dentistry of Kyungpook University Hospital during a eight and a half-year period, from April 1973 to September 1981. The majority of the patients in this series came from the city of Taegu and its vicinity. The results are as follows: The incidence of zygomatic fracture was most frequent in the second decade and males were predominant, representing 90.5% of the total, with the male to female ratio being 9.6: 1. Road traffic accidents were by far the most frequent cause of the zygomatic fractures, accounting for 62.l % of the total. Motorcycle accidents were responsible for 24.2% of the total. Of the 95 patients, 54 (56.9%) were injured on the left side, whereas the right side was affected in 38 (40.1 %) and 3 (3.2%) had bilateral fractures. There were relatively high incidence of associated laceration of the face, craniocerebral injury and fractures of the mandible and maxilla. Of the 46 patients treated surgically, 21(45.6%) were treated within 1 week after their injuries and 25 (54.4%) were treated during the second, third, and fourth week after injuries. The most commonly used method of surgical treatment was open reduction and interosseous wire fixation via lateral eyebrow approach.
