Ostéome mandibulaire post-traumatique

The etiopathogenesis of osteomas is controversial and several hypotheses are suggested. It is regarded as a true benign tumoral process, or abnormality of development, or as a reaction to trauma or infection. The development of osteoma after trauma has been described in several cases, notably in mandibular locations exposed to shocks (angle and lower edge). Multiple osteomas must mandatorily lead to screening for a Gardner's syndrome, because of the associated risk of colon cancer.
