ABSTRACT
Statement of Problem: Information about etiology and incidence of maxillofacial trauma is important for prevention and appropriate treatments of such injuries
Purpose: The purpose of this retrospective study was to conduct an analysis of maxillofacial injuries transferred and/or referred to the department of maxillofacial Surgery at Chamran emergency hospital, Shiraz, over a 6-year-period with special reference to age, gender, occupation, date, type, site, etiology and clinical management
Materials and Method: The data for this study were collected and reviewed retrospectively from the records and radiographs of 768 patients who were treated for maxillofacial trauma in the department of maxillofacial surgery at the Shiraz Chamran Emergency Hospital, Iran, between 2004 and 2010
Results: A total of 730 of the subjects were the patients with fractures of the facial skeleton. The mean age was 26.6 +/- 12.6 years, ranging from 2 to 81 years. Traffic accident was the most frequent etiological factor of maxillofacial fractures irrespective of gender [69.9% for men and 54.2% for women], whereas the second most frequent cause of injuries was falling down [9.8% for men and 21.5% for women] .The other etiologies were assault [5.2%], sport related injuries [1.3%] and firearm injuries [1%]. Regarding the head injuries in patients with maxillofacial fractures, brain contusion was seen in 227[29.6%] patients and 13.5% of patients had lacerations in the facial soft tissue. The monthly distribution peaked in October, with 81 cases [10.5%], which seems to have been due to schools opening. The next highest incidence was in December, with 80 cases [10.4%], probably because of the changing weather's effect on road traffic
Conclusion: Isolated mandibular fracture due to the road traffic accident was the most common type of maxillofacial injuries in the city of Shiraz
ABSTRACT
The main aim of advancement genioplasty is soft tissue and hard tissue stability which is important in improvement of the patients' aesthetics. The evaluation of the soft and hard tissue stability in advancement genioplsty was the aim of this study. The subjects in this study were 15 patients who presented with retrognathia. All of the 15 patients underwent advancement genioplasty alone to correct retrognathia. The soft and hard tissue pogonion in pre-operation, immediately post-operation, and 18 months after operation in tow groups of 9 patients with genial advancement equal or greater than 7 mm [means 7.16 mm] were assessed. After operation, no patient had infection or dehiscence and bone instability. In group 1 with advancement less than 7mm, hard tissue pogonion relapse was 0.60 +/- 0.66mm and soft tissue pogonion relapse was 1.55 +/- 0.46mm. I group 2 with advancement equal or more than 7mm, hard tissue pogonion relapse of 1.6 +/- 0.46mm and soft tissue pogonion relapse of 1.8 +/- 0.68mm were observed. Advancement genioplasty is a predictable operation specially when using rigid fixation. In this study, the result of operation in an 18 month period was stable
