Rotational thyrotracheopexy after cricoidectomy for low-grade laryngeal chrondrosarcoma

| Tartalmi kivonat: | OBJECTIVES: The complex laryngeal functions are fundamentally defined by the cricoid cartilage. Thus, lesions requiring subtotal or total resection of the cricoid cartilage commonly warrant total laryngectomy. However, from an oncological perspective, the resection of the cricoid cartilage would be an optimal solution in these cases. The poor functional results of the few reported cases of total and subtotal cricoidectomy with different reconstruction techniques confirm the need for new approaches to reconstruct the infrastructure of the larynx post cricoidectomy. STUDY DESIGN: Retrospective case series review. METHODS: Four consecutive patients with low-grade chondrosarcoma were treated by cricoidectomy with rotational thyrotracheopexy reconstruction to enable the functional creation of a complete cartilaginous ring that can substitute the functions of the cricoid cartilage. The glottic structures were stabilized with endoscopic arytenoid abduction lateropexy. Patients were evaluated with objective and subjective function tests. RESULTS: Tumor-free margins were proven; patients were successfully decannulated within 3 weeks. Voice outcomes were adequate for social conversation in all cases. Oral feeding was possible in three patients. CONCLUSION: Total and subtotal cricoidectomy can be a surgical option to avoid total laryngectomy in cases of large chondrosarcomas destroying the cricoid cartilage. The thyrotracheopexy rotational advancement technique enables the effective reconstruction of the structural deficit of the resected cricoid cartilage in cases of total and subtotal cricoidectomy. An adequate airway for breathing, swallowing, and voice production can be reconstructed with good oncological control. In cases where the pharynx is not involved, good swallowing function can also be achieved. LEVEL OF EVIDENCE: 4. Laryngoscope, 2016. |
