Figure 5: (a and b) Oblique axial view, just above the level of hyoid with cephalad angulation of linear transducer demonstrating sonoanatomy of valleculae on either side. Two different patterns were appreciated. (a) Linear hyperechoic air mucosal interface on either side of midline and (b) Air-filled rounded paired structures on either side of midline. (c) Corresponding oblique axial computed tomographic section (red lines – representing limit of ultrasound scan extent) V, valleculae; blue arrows, hyperechoic air mucosal interface of anterior wall of valleculae; SM: suprahyoid muscles
