Myositis ossificans is a rare condition characterized by heterotopic bone formation in soft tissues, often following trauma. Although it can occur in the maxillofacial region, cases involving the temporalis muscle are infrequent. We report a case of a 33-year-old man who developed severe limitation of mouth opening due to myositis ossificans following closed trauma to the temporal region. Surgical excision was performed. The excision resulted in dural exposure and a small tear, requiring repair with a temporalis fascial graft. This case highlights a rare complication of myositis ossificans in the temporalis muscle, emphasizing the importance of a cautious surgical technique to avoid dural injury while achieving adequate removal of heterotopic ossification.
骨化性肌炎是一种罕见的病症，其特征为软组织中异位骨形成，常继发于创伤后。虽然它可发生于颌面区域，但累及颞肌的病例并不常见。我们报告一例33岁男性患者，其因颞部闭合性创伤后发生骨化性肌炎而导致严重张口受限。进行了手术切除。切除导致硬脑膜暴露和一个小裂口，需要用颞肌筋膜移植片进行修复。该病例凸显了颞肌骨化性肌炎的一种罕见并发症，强调了谨慎的手术技巧在避免硬脑膜损伤同时充分切除异位骨化的重要性。
