X-ray. X-ray and CT reconstruction showed an anterior hyperostosis from C2 to C7 (Fig. 1a). VFE showed contrast medium residue in the valleculae at the level of C3/4 (Fig. 1b), but no retention in the pyriform sinuses or esophageal inlet. The patient underwent localized and limited resection of the anterior beak-like osteophytes from C3 to C4 (Fig. 1c). Postoperative VFE showed no remaining obstruction and he had no complaints of dysphagia during the swallowing of both solid and liquid boluses at follow-up (Fig. 1d).

X-ray. X-ray and CT reconstruction showed an anterior hyperostosis from C2 to T3, especially on the right side (Fig. 2a, b). VFE showed contrast medium residue in the valleculae, right side pyriform sinus, and esophageal inlet (Fig. 2c). VFE revealed no obstruction at the level of C3 to C4 (no contrast medium residue in the valleculae), and reduction in contrast medium residue in the right side pyriform sinus was observed three weeks postoperatively (Fig. 2d).
