Summary: 
a, c) Laryngeal ultrasounds and b, d) schematic illustrations of an intubated patient who did not develop post-extubation stridor. When the balloon cuff on the endotracheal tube is inflated (a and b) the column of air (AC) passing through the true vocal cords (TVC) appears as a square. The hypoechoic true vocal cords can be seen on both sides of the column of air. The hyperechoic arytenoid cartilages (HAC) are located behind the true vocal cords and adjacent to the column of air. When the cuff is deflated (c and d) the column of air passing through the true vocal cords appears as a trapezoid and the width of the air column increases. In addition, the acoustic shadow of the laryngeal air column masks the hyperechoic arytenoid cartilages and part of the true vocal cords. Arrow indicates the width of the air column. T: thyroid cartilage. Reproduced from [116] with permission from the publisher.
