Surgical closure of the larynx for intractable aspiration pneumonia: cannula-free care and minimizing the risk of developing trachea–innominate artery fistula

There is a risk of developing a fatal trachea–innominate artery fistula following laryngotracheal separation for the prevention of intractable aspiration pneumonia. We developed a novel technique of surgical closure of the larynx to avoid this complication and provide long-term cannula-free care.
