Dentigerous cysts are commonly encountered associated with impacted teeth; however the exact histogenesis of these cysts is not known even though numerous theories have been proposed. Majority of the maxillary cysts arise as a result of defect in the embryonal development, which can be either abnormal fusion of facial processes or as a result of abnormality in the development of dental follicle. Congenital Tessier's number 7 unilateral facial cleft is a rare anomaly, which arises as a result of defect in the fusion of facial processes. We report an unusual case of concomitant occurrence of Tesssier's number 7 cleft and maxillary dentigerous cyst in 11-year-old child.
Aim: To analyze etiology, incidence and management of facial trauma over a period of 5 years in a tertiary care center in North India.
Materials and methods:Records of 195 patients with 274 facial fractures were analyzed retrospectively from 2009 to 2013. Fractures were classified according to anatomical area involved (zygoma, maxilla, mandible, teeth), and etiology was divided into road traffic accidents (RTAs), falls, sports injuries and assaults. It was found that RTA was most common etiologic factor for facial trauma, followed by falls, assaults and sports injuries. Mandibular fractures were most common, followed by midface fractures and dental injuries. Various treatment options were also evaluated.Results: Mandibular fractures were more common than midface fractures. Most common line of treatment was open reduction and internal fixation with mini-plate fixation. Mandible reconstruction was done in one case of bone defect following a gun-shot injury. Coronoidectomy had to be performed in one case of zygoma fracture.
Conclusion:Patient's best interest, affordability and general well being should be kept in mind while managing trauma of maxillofacial region. Surgeon should utilize his knowledge to the best possible level as any injury to this region has a direct impact on psyche as well as general well being of patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
