ABSTRACT
INTRODUCTION: The temporomandibular joint (TMJ) is a complex joint, and it allows bilateral synchronous rotatory and translatory movements. TMJ reconstruction has evolved as an important step in the management of conditions affecting the TMJ like ankylosis, traumatic injuries and congenital deformities. Distraction osteogenesis (DO) is a biological process of forming new bone and adjacent soft tissues by gradual and controlled traction applied on osteotomized bone segments. CASE REPORT: Here is a case report of bilateral TMJ ankylosis which was managed effectively by resection of ankylotic mass and reconstruction of TMJ by transport distraction osteogenesis with preoperative vector planning using a 3D printed model. CONCLUSION: Distraction osteogenesis can be considered as an effective means of condylar reconstruction for an anatomical and functional TMJ with minimal complications. Use of 3D models can help making such complex TMJ reconstruction procedures simpler.
ABSTRACT
Incidence and etiology of facial fractures vary from region to region due to various constituents. This study was carried to evaluate the patterns and distribution of fractures in the facial region among different age groups of patients in both males and females caused due to various etiologies. This is a retrospective epidemiological study, which was performed on patients with fractures in the maxillofacial region during a period of 2005 to 2013 at Mamata Dental College and Hospital, Khammam, India. A total of 1,015 patients with 1,545 fractures were referred for treatment to department of oral and maxillofacial injuries surgery, of Mamata Dental College and Hospital, with a mean age of 31.19. The ratio of males (859):females (156) is 5.5:1. Injuries caused by motorbike injuries (34.9%) are highest. The highest frequency of fractures caused by various reasons is seen more in third decade (39%). Mandible (43.81%) is the most common fracture site in the face. Among soft tissue injuries most commonly seen are lacerations (43%). This study differentiates the etiological factors causing facial trauma in several age groups. Results of this study suggest outcomes indicate that more reliance on individual transport on motor vehicles has increased the frequency of facial bone fractures. Regardless of age, motor vehicle accidents were high in all age groups except the first decade of life and above 60 years of age when traffic accidents dominated. Thus effectiveness of current preventive measures is to be assessed, followed by instituting new guidelines for prevention and inflexible traffic rules shall be levied. More epidemiological surveys can, if encouraged to measure the frequency of fractures, better the world.
