Endoscopic or open arytenoidectomy is another approach for enlarging the posterior glottic airway. The technique for endoscopic laser arytenoidectomy, as Ossoff et al elucidated in 1984, allows for the direct and relatively atraumatic ablation of the arytenoid cartilage without the morbidity of an external incision. [15] The addition of direct laser ablation to the armamentarium improved the relative ease of performance when compared to the endoscopic delivery and excision technique previously described by Thornell. Disadvantages of laser arytenoidectomy include the attendant airway risks of CO2 laser surgery, including airway fires and peripheral thermal damage.
