Background The zygoma complex fracture is common injury of the middle facial skeleton. Modern treatment of zygoma complex fractures includes open reposition and fixation with titanium mini plates. The purpose of our study was to analyse the postoperative complications and consequences of zygoma complex fractures treated between 1999 and 2003 in the Clinical Department of Maxillofacial and Oral Surgery at University Clinical Centre in Ljubljana. We hypothesised that the longer the time between injury of zygoma complex and treatment the bigger the chance for the injury to the infraorbital nerve. Another hypothesis was that the outcome of the treatment is dependent upon thesurgical approach. Methods There were 345 patients treated at the Clinical Department for Maxillofacial and Oral Surgery because of the zygoma fractures between 1999 and 2003. Different surgical methods were used. The data were obtained retrospectivelly, pre- and postoperative images were assesed. At least 2-year follow-up was taken in account. All patients were sent the questionnaire about their sensitivity of the infraorbital nerve. The data wererevised by simple statistics for mean values and standard deviations and ANOVA statistics for regression analysis with linear, multiple regression, hystogram, Chi-squared tests. Results Between observed 345 patients men were predominant in 80%, the average age was 38.2 years, more than 65% of patients were between 20 and 65 years old. The most common causes of zygoma complex fractures in Slovenian population are traffic accidents in 26% and assaults in22%; sports accidents had increased in this period. The mean time between the injury and surgery was 9 days, but the part of operated patients in first week after fracture had significantly increased in observed period. Treatment by closed reposition decreased from 59% in 1999 to 17% in 2003. (Abstract truncated at 2000 characters)
