title: Endoscopic resection of low grade, subglottic chondrosarcoma.
abstract: BACKGROUND
  This paper evaluates the feasibility of transoral, endoscopic resection of macroscopically localised, low grade, subglottic chondrosarcoma.
  
  
  METHODS
  Retrospective case study including patients diagnosed with low grade, subglottic laryngeal chondrosarcoma. Tumours were resected endoscopically via direct laryngoscopy with microlaryngeal technique, under jet ventilation. The post-operative course, vocal fold function, airway patency and oncological results were evaluated.
  
  
  RESULTS
  Two male patients aged 49 and 60 years underwent endoscopic, translaryngeal, en bloc resection of low grade chondrosarcoma of the cricoid cartilage. Extubation was performed immediately after surgery. Neither patient required tracheostomy or developed subglottic stenosis. No tumour recurrence was noted after an average follow up of 10.5 months. Voice quality was stable and dyspnoea improved.
  
  
  CONCLUSIONS
  Transoral, endoscopic resection of low grade, subglottic chondrosarcoma is a viable technique with good functional outcomes. Extensive resection of subglottic disease is possible, which may afford patients an alternative to total laryngectomy.
