Concept in Surgical Technique in Subglottic Chondrosarcoma

Laryngeal chondromas are very uncommon cartilaginous benign tumors of the larynx. Although, total laryngectomy is reserved for high-grade laryngeal chondrosarcomas, some studies indicate that conservative approach in typical chondrosarcoma has increased the occurrence of local recurrence. Two cases of cricoid chondrosarcoma and chondroma is reported in young adult men with obstructing the laryngeal lumen without vocal cord paralysis. The chondroma and chondrosarcoma were totally excised through a laryngo-fissure approach to protect laryngeal function. Minimal invasive operation through a laryngo-fissure approach may yield a proper laryngeal function without any recurrence of the chondroma and chondrosarcoma for more than 2 years after operation time.
