Traumatic Bone Cyst of Mandible

The traumatic bone cyst, an uncommon lesion of the jaws, belongs to the category of 'pseudocyst' owing to its lack of a lining epithelial membrane. It is an asymptomatic lesion, which is often diagnosed accidentally during routine radiological examination commonly present in the posterior mandible as a unilocular radiolucency with scalloping borders. The exact etiopathogenesis of the lesion is still debated, though the role of trauma is often associated. Here we report a rare case of traumatic bone cyst in the anterior mandible, in a 16-year-old female patient with a previous history of trauma to chin; diagnosed and treated successfully in our surgical unit. The case is discussed in relation to its clinical presentation, etiopathogenesis, diagnosis, management and prognosis.
