title: The digital AcuBlade laser system to remove huge vocal fold granulations following subglottic airway stent.
abstract: We report a case of granulations that complicated subglottic stent placement and completely destroyed vocal folds with luminal stent obstruction. A microbial aetiology significantly contributed to the occurrence of granulations associated with mechanical irritation. The granulations were successfully resected using a digital AcuBlade laser system, a new generation of CO2 laser used in otorhinolaryngology, particularly in vocal cord disease. It permitted a precise control of the scan line between vocal fold and granulation for several reasons. The scan line was completely electronic and integrated in the scanner. The sweep in speed was constant and the energy distribution was uniform along the entire length of the time. The interpulse pause was of ∼1 ms, allowing the tissue cooling with reduction of thermal spread and quicker healing support. The result was the radical excision of granulations without injuring vocal folds. The respiratory function was restored and no other treatments such as arytenoidectomy or cordectomy associated with the alteration of phonatry function were required. No intraoperative or/and postoperative complications were registered and the patient was discharged 7 days after the procedure.
