A<unk>  is the surgical excision of the cricoid cartilage. The excision can often be performed under local anaesthetic and can either be partial or total. The procedure may be necessary as a treatment of pulmonary aspiration, to prevent progression to aspiration pneumonia. As the cricoid cartilage is the narrowest part of the trachea, it is also a common point of a blockage or narrowing (stenosis).
