Functional optimisation in chondrosarcoma of the subglottis: a novel surgical approach.

Chondrosarcoma of the larynx is rare accounting for approximately 1% of laryngeal cancers; clear cell subtype is a rare variant. Given the low risk of occult nodal disease, they present a unique opportunity to maximise tissue preservation in order to optimise both recovery and long-term functional outcomes. We present a case of laryngeal clear cell chondrosarcoma causing critical airway obstruction. An emergency tracheostomy was performed and mapping biopsies were taken. The tumour originated from the cricoid and extended into both arytenoid superstructures precluding cricotracheal resection. A modified narrow-field laryngectomy was performed, preserving all pharyngeal mucosa and neurovascularly intact infrahyoids. Organ preservation surgery is preferred in the management of laryngeal chondrosarcoma. If laryngectomy is required, the surgeon must ensure that all uninvolved, functional tissue is preserved carefully to improve swallow and voice outcomes postoperatively. We describe a novel technique used to achieve this outcome.
