  • Title: An Unusual Case of Severe Trismus After Craniotomy.
    Author: Graca S, Houle A, Callahan N.
    Journal: J Craniofac Surg; 2023 Jun 01; 34(4):e348-e350. PubMed ID: 36727759.
    Abstract:
    Myositis ossificans Traumatica (MOT) is a non-neoplastic, heterotrophic ossifying disease process in muscle and soft tissue rarely involving the craniofacial area. Treatment depends on the extent of ossification and functional limitations. We present the first case of MOT of the temporalis muscle following neurosurgical intervention. This is the case of a 28-year-old male patient who underwent numerous neurosurgical interventions and reported progressive trismus following these interventions. Imaging demonstrated a right temporal region radio-opacity consistent with ossification of the temporalis muscle. The patient underwent coronoidectomy with excision of the ossified right temporalis muscle and reconstruction with an anterolateral thigh adipofascial vascular free flap. Postoperatively, he maintained intact function with increased incisal opening and no cosmetic defects. Limited mouth opening after the neurological procedure has a wide differential, and MOT must be considered. Surgical repair and reconstruction are multifaceted problems. Free flap reconstruction should be considered in multiple operated patients.
