Beak of a needlefish. Coronal oblique CT image (a) and 3-dimensional volume rendering (b) showing a dislocated hyperdense foreign body (arrow) piercing through the auricle and traversing through the soft tissues rostral to the external acoustic meatus/posterior to the temporomandibular joint discus in close proximity to the petrotympanic fissure. The tip is visualised posterior to the lateral pterygoid muscle, implying its close relationship to the mandibular nerve and the maxillary artery.
