(1,5) It is also known as post-traumatic heterotopic ossification, non-hereditary heterotopic ossification and myositis ossificans circumscripta. (3,6) Radiographic imaging is used for a definitive diagnosis with evidence of bone formation being detected 3 to 4 weeks after the initial trauma.
5 Some authors believe myositis ossificans traumatica to be an inadequately descriptive term because in as many as 25% of cases, no history of trauma can be obtained.6 Apart from myositis ossificans progressiva, which has a genetic origin, European authors have described two other variants of myositis ossificans as traumatic myositis ossificans circumscripta and atraumatic myositis ossificans circumscripta.7 These authors have suggested an infective origin to atraumatic myositis ossificans.8 In the present case report history of trauma during mastication was estab- lished.
