Traumatic myositis ossificans (TMO) is a rare ossifying disease that occurs in the muscle or soft tissues. A case of TMO isolated in the temporalis muscle is reported. In the case described, calcification in the temporalis muscle was confirmed after computed tomography. Surgery, physiotherapy, and histopathological analysis were performed. One year after treatment, further ossification was present but without interference in function. The most accepted treatment for TMO in the maxillofacial region is excision followed by physiotherapy. The high rate of non-recurrence may be concealed due to the short follow-up period. TMO is a lesion that may frequently recur and long-term follow-up must be provided.
