Subglottic chondrosarcoma treated with transoral laser microsurgery: Case series and literature review

Subglottic chondrosarcoma (SGC) is a rare entity that is traditionally treated with open resection. We detail two cases treated with CO2 transoral laser microsurgery (TLM) and present a literature review of minimally invasive approaches to this disease. Retrospective chart review and search of English language literature are important methods of data collection. Case Series: Two patients were identified. Both presented with worsening dyspnea and stridor. One patient had intermediate grade disease and the other had low grade disease. Both patients were successfully treated with TLM and remain disease free at 42 and 17 months respectively with good voice and functional outcomes. Conclusion: We present two cases of SGC treated with curative intent minimally invasive TLM. In both cases, there is no evidence of disease recurrence or functional limitation at follow-up. These findings are in line with the favorable oncological and functional outcomes demonstrated in the literature describing SGC treatment with TLM.
