BACKGROUND The condition of mediastinal chondrosarcoma causing severe airway compression has never been reported before, and its complexity makes its surgical management challenging. We implemented two new techniques to overcome this problem. Creative mockup analogy of a distorted trachea and tumor lesion using a 3-D printing module, with reprogramming by computed tomography, streamlined the panorama with intricate correlation. CASE PRESENTATION Our patient was a previously healthy 52-year-old slender yellow man who had no obvious medical history. In the last 3 years, upper respiratory tract infection and productive cough were noted frequently, and the patient's symptoms were aggravated with shortness of breath when his head was positioned below 90 degrees during squatting and hunching of the body. The patient manifested prone sleep with ashen complexion, and he had lost 3-4 kg of body weight over the 3 weeks before admission to our hospital. Virtual bronchoscopy with computed tomography revealed an 8.3 × 7.5 × 4-cm lobulated right upper mediastinal mass with amorphous calcification and severe, intricate airway compression. A creative mockup analogy module of the distorted trachea and tumor was generated by 3-D printing and reprogrammed by computed tomography to streamline the sophisticated correlation. The patient underwent a two-stage operation comprising stabilization of the airway for innovative T-tube insertion preceded by thoracoscopy-assisted radical removal of the tumor. Postoperative adjuvant radiotherapy was administered. The patient recovered uneventfully and stayed healthy for 2 solid years in follow-up. CONCLUSIONS An advanced 3-D printing model provides affirmative information related to treatment strategy and is also a prospective tool for better doctor-patient communication regarding the disease.

3-D打印模型用于简化由破坏性纵隔软骨肉瘤引起的复杂气道压缩情况的手术程序：一例病例报告。

背景技术以前从未报道过引起严重气道压迫的纵隔软骨肉瘤的状况，其复杂性使其手术管理具有挑战性。我们实施了两种新技术来克服此问题。使用3-D打印模块对气管和肿瘤病变畸形进行创造性的模型模拟，并通过计算机断层扫描重新编程，从而简化了具有复杂相关性的全景图。病例介绍我们的患者是一位以前健康的52岁苗条的黄色老人，没有明显的病史。在最近的3年中，经常注意到上呼吸道感染和生产性咳嗽，并且在蹲着和弯腰的过程中将头部置于90度以下时，患者的症状会因呼吸急促而加重。该患者表现出容易出现睡眠和灰白色的症状，入院前3周体重减轻了3-4公斤。使用计算机断层扫描技术的虚拟支气管镜检查显示右上纵隔有8.3×7.5×4 cm的小叶，无定形钙化和严重，复杂的气道压迫。通过3-D打印生成了变形的气管和肿瘤的创新模型样机模块，并通过计算机断层扫描重新编程以简化复杂的相关性。患者接受了两个阶段的手术​​，包括稳定气道以进行创新的T型管插入，然后进行胸腔镜辅助的肿瘤根治术。术后进行辅助放疗。病人恢复良好，并在随访中保持健康2年。
