Chondrosarcoma is a rare laryngeal neoplasm that is most commonly encountered in the cricoid cartilage and is optimally treated by surgical excision. It is typically a slow-growing malignancy with well-defined margins and a minimal risk of metastasis; however, radiographic imaging studies often appear ominous if the clinician correlates these findings to the biological behavior of epithelial cancer. Furthermore, the fact that the neoplasm's epicenter is usually under the cricoarytenoid joint can lead to airway and voice deficits before and after operation. Although many surgeons opt for function-sparing resection approaches, it is commonplace for some surgeons to injudiciously perform total laryngectomy as the initial treatment because of the rarity, large size, location, and appearance of these tumors on imaging studies. A retrospective review was done on 10 cases of cricoid chondrosarcoma to gain insight into the treatment strategies designed to preserve laryngeal function while minimizing the risk of local recurrence. We performed surgical resection in 8 of the 10 patients; 2 underwent endoscopic removal and 6 underwent transcervical partial laryngectomy. All are free of disease with good voice and swallowing function. One patient developed a limited recurrence and required a second transcervical partial laryngectomy. Function-sparing surgical treatment of chondrosarcomas of the cricoid cartilage can usually be achieved. Surgeons should carefully modify the core principles of epithelial cancer surgery techniques, adjusting to the different biological behavior of laryngeal chondrosarcomas.
软骨肉瘤是一种罕见的喉部肿瘤,最常见于环状软骨,最佳治疗方法是手术切除。它通常是一种生长缓慢的恶性肿瘤,边界清晰,转移风险极小;然而,如果临床医生将这些影像学检查结果与上皮癌的生物学行为相关联,影像学检查结果往往看起来不乐观。此外,肿瘤的中心通常位于环杓关节下方,这可能导致手术前后出现气道和声音功能障碍。尽管许多外科医生选择保留功能的切除方法,但由于这些肿瘤在影像学检查中的罕见性、大尺寸、位置和外观,一些外科医生不明智地将全喉切除术作为初始治疗方法的情况并不少见。对10例环状软骨软骨肉瘤病例进行了回顾性研究,以深入了解旨在保留喉部功能同时将局部复发风险降至最低的治疗策略。我们对10例患者中的8例进行了手术切除;2例接受了内镜下切除,6例接受了经颈部分喉切除术。所有患者均无疾病,声音和吞咽功能良好。1例患者出现局限性复发,需要再次进行经颈部分喉切除术。环状软骨软骨肉瘤的保留功能手术治疗通常是可以实现的。外科医生应仔细调整上皮癌手术技术的核心原则,以适应喉软骨肉瘤不同的生物学行为。
