Patient-specific PEEK implant for treatment of temporal myositis ossificans (five years follow-up): A case report.

Myositis ossificans of the temporalis muscle results in a cosmetic problem both before and after treatment because of the preoperative swelling and the postoperative defect respectively. The authors hypothesized that a patient-specific Polyether-ether ketone implant can be appropriate for immediate obliteration and reconstruction of such defect benefiting from the accuracy of CAD/CAM technology and computer-guided maxillofacial surgery. A Forty-year-old male patient with myositis ossificans affecting the left temporalis muscle was treated with a computer-guided surgical approach, a patient-specific implant was fabricated to obliterate the defect and avoid temporal hollowing using PEEK material. The functional and cosmetic results were satisfactory both immediately and at the 5-year follow-up, except that the skin over the implant was noticed to be stretched after 5 years. Hence, it can be concluded that virtual surgical planning and PEEK patient-specific implants are reliable in the immediate reconstruction of post-surgical temporal hollowing.
