This paper reports on apparently the first case of a pharyngeal osteoma that developed from the hyoid bone. An 84-year-old man's, presenting symptom was a slight throat pain. Endoscopic examination revealed a huge mass occluding the pharyngeal space. CT scan of the neck showed a large osseous mass adjacent to the hyoid bone. Transoral resection with tracheostomy was performed. Histopathologically, the tumor consisted of mature lamellar bone without a fibrous component. For two years postoperatively, the patient has been free from throat symptoms and signs of recurrence. Osteomas are benign, slow-growing tumors. They rarely develop symptoms or cause functional disturbance. We performed total resection to avoid further functional disturbance as the osteoma was huge. To the best of our knowledge, this is the first report on an osteoma that occupied the pharyngeal space and developed from the hyoid bone.
本文报道了首例明显起源于舌骨的咽骨瘤病例。一名84岁男性，主要症状为轻微咽痛。内镜检查发现一个巨大肿物阻塞咽腔。颈部CT扫描显示舌骨旁有一个大的骨质肿物。行气管切开经口切除术。组织病理学检查显示肿瘤由成熟板层骨组成，无纤维成分。术后两年，患者无咽痛症状及复发迹象。骨瘤是良性、生长缓慢的肿瘤。它们很少出现症状或引起功能障碍。由于骨瘤巨大，我们进行了全切以避免进一步的功能障碍。据我们所知，这是首例关于占据咽腔并起源于舌骨的骨瘤的报道。
