Abstract
OBJECTIVE
The aim of the present study was to study the etiologies and patterns of maxillofacial fractures in patients treated in Riyadh City, Saudi Arabia, between 2007 and 2011.
PATIENTS AND METHODS
Data were obtained through a retrospective review of 237 patients admitted to the King Saud Medical City Dental Department with a diagnosis of maxillofacial trauma. After excluding patient files with incomplete or unclear records, and cases in which computed tomography showed no evidence of fracture, the files of 200 patients with a diagnosis of maxillofacial fracture were included in the study. For each case, patient's sex and age, pattern of facial fractures, and cause of injury were recorded on a data sheet. The data were transferred to an SPSS (ver. 16.0; SPSS Inc., Chicago, IL, USA) spreadsheet for statistical analysis. The chi-square test was used to test the association between two categorical variables or factors (age group, cause) with p value set at p<0.05, and t-test value at <0.05 and independent.
RESULTS
Motor vehicle accidents were the most common cause of maxillofacial fractures in most age groups, especially in males. Within the study sample, mandibular fractures were significantly more common than middle-third facial fractures (56.4% vs. 43.6%; p=0.006). Among mandibular fractures, parasymphyseal fractures were most common (47%), followed by condylar fractures (35.3%). Most (77.2%) middle-third facial fractures involved the zygomatic complex, and the incidence of such fractures differed significantly between male and female patients. p=0.72, not significant.
CONCLUSION
Males were more prone to maxillofacial fractures, perhaps as a result of the conservative nature of Saudi society, as the rules of Saudi Arabia do not allow the females to drive. Motor vehicle accidents were the most common cause of maxillofacial fractures in patients aged 10-29 years, indicating the high demand for the application of stricter traffic rules to reduce the rate of such accidents.
