Figure 8: (a) Split/dual axial sections overlying thyroid cartilage using a linear transducer, demonstrating sonoanatomy of step 7 structures of either side (hypopharynx). (b) Corresponding computed tomographic section (red lines – representing the limit of ultrasound scan extent on either side) PF: Pyriform fossae; Red arrows, Thyroid cartilage; Blue arrows, Aryepiglottic folds; Yellow arrows, air-mucosal interface of larynx
