16 Use of digital photography and 3D reconstruction in the evaluation and planning of maxillofacial trauma treatment R. Cosmelli Maturana 1,∗ , O. Badillo Coloma 2 , R. Osben Moreno 2 1 Oral and Maxillofacial Surgery, University of Valparaiso, Chile 2 Hospital Carlos van Buren, Valparaiso, Chile
Introduction: The aim of this paper is to present a system analysis by digital photography and reconstruction in three dimensions (3D) using the OsiriX program for Mac OS X® , which can be helpful in the evaluation, diagnosis and treatment planning of patients with maxillofacial trauma requiring a surgical solution. Material and methods: We present a series of 5 patients with various fractures in the maxillofacial area where digital photographs and CT were taken. Tomographic information was recorded in DICOM format and analyzed with OsiriX for MAC OS X® , and 1:1 scale photographs for analysis and measurement. Maxillofacial Surgery Department Protocol from Hospital Carlos van Buren in a pre and post operative way, comparing the planning proposed with what was done in the operating room at the time of surgery. Results: All pre and postoperative images matched with reconstructions and previously. Conclusion: It is an objective method to predict surgical outcome based on the integration of measures. It is also a useful tool for diagnosis and preoperative planning in patients with maxillofacial trauma, this avoids wasting time and resources. Conflict of interest: None declared. doi:10.1016/j.ijom.2011.07.279
17 Fractures of the orbital cavity: prospective review of 12 cases in the Carlos van Buren Hospital in Valparaiso R. Cosmelli Maturana 1,∗ , O. Badillo Coloma 2 , R. Osben Moreno 2 , V. Duarte 2 , R.

Introduction: Trauma in the orbital region can result in considerable facial deformity and can affect vision and the nervous system of the face. Rehabilitation of the patient requires to understand the
alteration of the orbit’s shape and function, including intraorbital and intraocular tissues, and materials and methods available for its repairs. The aim of this study is to evaluate prospectively the clinical manifestations and treatments carried out in fractures of the orbital cavity in the Maxillofacial Surgery Service Hospital Carlos van Buren de Valparaíso. Material and methods: Patients were analyzed according to gender, age, trauma mechanism, associated symptoms, method of treatment. Results: 12 patients were analyzed, 9 men and 3 women with an average age of 30.9 years old, fights represented 33.3%, the major clinic sign was diplopia accounting for 58%, 83% was open reduction and rigid fixation. Conclusion: Our review showed that fractures of the orbital cavity were resolved satisfactorily and in line with those reported in the literature.

18 Spontaneous bone regeneration in mandible after necrosis after facial trauma, case report L.H. Rau 1,2,3,∗ , J.D.O. Ribas Filho 1 , L. Mores 1 1 Oral and Maxillofacial Surgery, Hospital Infantil Joana de Gusmão, Brazil 2 Oral and Maxillofacial Surgery, Imperial Hospital de Caridade, Brazil 3 Oral and Maxillofacial Surgery, Hospital Baía Sul, Florianópolis, Brazil
Introduction: Bone regeneration in the mandible has been described in the literature after the resection because of several pathologies. This development of new bone seems to occur from the periosteum or its fragments. It is most common in the young population although it can appear in elder patients. Case report: A 07 years old girl, visited the Pediatric Service of Oral and Maxillofacial Surgery in Florianópolis, Brazil, with necrosis in the anterior mandible after a trauma, caused by a car accident, which demanded to be resected and fixed with a reconstruction plate. Prosthetic device was installed to recover the function of the mandible while the patient is waiting for the definitive rehabilitation with Titanium Implants. Some months later, during the periodic visit, the Computerized Tomography showed a new bone formation in the region that still evolving and increasing the bone
neoformation area. Now, we are in 06 years follow up. Purpose: The purpose of this poster is to expose to the scientific community another case of this uncommon and unexpected regeneration, thus avoiding many unnecessary reconstruction surgeries. Conflict of interest: None declared. doi:10.1016/j.ijom.2011.07.281
19 Remodelling and function of the fractured mandibular condyles repositioned after extra-corporeal reduction & internal fixation M. Kim ∗ , S. Kim, J. Jang Oral and Maxillofacial Surgery, Ewha Womans University, Seoul, Republic of Korea
The objective of this study was to evaluate the prognosis of the fractured mandibular condyles which were repositioned after internal fixation by extracorporeal open reduction. The subjects were 19 patients who underwent open reduction & internal fixation for the fractured mandibular condyles and followed-up for 10 years since 2000 at the Ewha Womans University Medical Center, Seoul, Korea. Radiologic changes in the remodeling phases, range of mouth opening, lateral excursion of the jaw, TMJ pain, facial disfigurement with occlusal changes were examined by radiologic images, virtual measurement, and kinesiographs. Their ages were 32.0 ± 21.6 years old. All patients could open their mouth to over 35 mm postoperatively and up to 45 mm in 7 patients (37%). Lateral excursions were limited to 5–10 mm. The condyle heads disclosed resorption and remodeling within 6 months resulting shortening of the length, but no findings of necrotic resorption in the repositioned ramus and condyles. Pain & tenderness of TMJ were followed in one patients who had bilateral comminuted fractures and previous ORIF. There were no difference between closed reduction and extracorporeal reduction in mouth opening & jaw excursions compared to the control group (closed reduction). Conflict of interest: None declared. doi:10.1016/j.ijom.2011.07.282
