Fig 1. Fluoroscopic fistulogram of a first branchial cleft anomaly. Lateral (A) and frontal (B) projections demonstrate the course of the fistulous tract from the skin overlying the angle of the mandible (black arrow) to the external auditory canal (white arrow). The external auditory canal is filled with contrast (E). Note the small filling defect (arrowhead) in the midportion of the anomaly. The angiocatheter remains in position on the lateral projection (curved arrow).
