“…Myositis ossificans traumatica (MOT) is a rare and unusual disorder which effectively causes extra‐articular temporomandibular joint ankylosis when it affects the muscles of mastication. Within the literature, 30 cases of MOT of the muscles of mastication have been reported 1,3–30 . A summary of these 30 cases is presented in Table 1.…”

“…These events would usually be preceded by an episode of acute or chronic trauma 29 . A possible explanation of MOT occurrence within the masseter muscle is that, anatomically, this muscle is most likely to receive the full impact of any direct trauma, for example, as a result of inter‐personal violence 1,3–30 .

“…It usually affects a single/local muscle following either acute or chronic trauma/inflammation and its incidence within the maxillofacial region is extremely low. To our knowledge, there have only been 30 cases reported in the literature of MOT of the muscles of mastication between 1924 and 2002 1,3–30 . The following case describes a 15 year follow‐up of a patient who developed MOT of the temporalis and pterygoid muscles following surgical removal of a lower wisdom tooth.…”

Trismus is a frequent post-op sequelae of third molar surgery. A history of long-standing post-operative trismus warrants further investigation. Myositis ossificans traumatica (MOT), as its name implies, is ossification and bone formation within muscle following an episode of trauma. When it affects the muscles of mastication, it causes severe trismus. This rare disorder and its limited treatment options can potentially have debilitating effects to the patient's normal oral functioning and health. The following is a case report of a patient who developed MOT of the muscles of mastication following surgical exodontia of a lower wisdom tooth, the progress over a 15 year period and a review of the literature. This case demonstrates the longterm difficulties in managing MOT of the muscles of mastication.

We report a case of a calculus-like calcified body on the buccal region. The patient was a 68-yearold man. He was referred to our hospital for further examination due to opaque images found in front of the left mandibular branch on panoramic radiography. Findings from the first visit confirmed a hard mass with a diameter of 10 mm under the left buccal mucosa. There were no subjective symptoms, and saliva outflow from the parotid papilla was good. CT findings showed a high-density structure (1300 HU) about 11 × 9 mm in size.It was circular and clearly demarcated on the outer side of the mandible, left of the masseter muscle anterior margin. The lesion was located slightly below the parotid duct, and there was no apparent continuity with the parotid duct. Extirpation of the mass was performed through an intraoral approach with the patient under general anesthesia. There was no contact between the lesion and the parotid duct. The excised substance was a calcified body 10 × 10 × 13 mm in size covered with a thin capsule of connective tissue. Histopathologically, the body comprised calcified material with a concentric laminated plate structure, while the surrounding capsule comprised fibrous tissue with plasma exudate and bleeding. No conduit structure was found. The final diagnosis was heterotopic calculus-like calcification. The postoperative course was uneventful.
