    • ‘It was almost certain, however, that the stenosis extended beyond the level of the cricothyroid membrane and probably below the level of a surgical tracheostomy.’
    • ‘The surgeon identifies the anatomical landmarks (ie, thyroid notch, cricothyroid membrane, inferior margin of the cricoid cartilage) and marks them.’
    • ‘In addition to supplying the inferior constrictor muscle of the pharynx, the nerve may supply the cricothyroid muscle.’
    • ‘Neck circumference was taken at the level of the cricothyroid membrane, waist circumference at the level of umbilicus, and hip circumference at the maximal girth level.’
    • ‘Finally, pressure on the cricothyroid membrane may help visualize the trachea and vocal chords.’


Mid 19th century: from Greek kriko- (combining form of krikos ‘ring’) + thyroid.
