Myositis ossificans is a rare disease that is characterized by bone deposition in the muscle or soft tissues. Myositis ossificans of the masticatory muscles is an uncommon finding. The condition is benign and results in heterotopic bone formation in the muscles of mastication, usually producing limitation of opening of the jaws. It is important to know the exact cause of the limitation of opening of the jaws for successful treatment. Computed tomographic scan and panoramic radiographs along with histological findings are essential diagnostic aids for evaluating conditions such as myositis ossificans. A rare case of myositis ossificans traumatica of temporalis and medial pterygoid muscle is presented here along with the discussion of clinical, radiological and histological features. The present case emphasizes not only on the importance of considering myositis ossificans in the differential diagnosis of limitation of opening of the jaws but also on the improvement of the overall mouth opening and treatment results.
骨化性肌炎是一种罕见疾病，其特征是在肌肉或软组织中出现骨沉积。咀嚼肌骨化性肌炎是一种不常见的表现。这种情况是良性的，会导致咀嚼肌中出现异位骨形成，通常会导致张口受限。为了成功治疗，了解张口受限的确切原因很重要。计算机断层扫描和全景X线片以及组织学检查结果是评估骨化性肌炎等病症的重要诊断辅助手段。本文介绍了一例颞肌和翼内肌创伤性骨化性肌炎的罕见病例，并讨论了其临床、放射学和组织学特征。本病例不仅强调了在张口受限鉴别诊断中考虑骨化性肌炎的重要性，还强调了改善整体张口度和治疗效果的重要性。
