Surgical management of dysphagia at the oropharyngeal-esophageal junction due to cervical spondylosis: Two case reports

Figure 1 Imaging findings in case 1. A: A barium swallow test of the upper gastrointestinal tract revealed contrast agent accumulation in the pharynx, with partial aspiration into the trachea; B: The gastroscopic examination revealed an area of extrinsic compression or an extrinsic pressure-type bulge on the posterior wall of the hypopharynx; C: Cervical magnetic resonance imaging demonstrated intervertebral disc herniation at the C3-C4, C4-C5, C5-C6, and C6-C7 levels.

Figure 2 Imaging findings in case 2. A: The gastroscopic examination revealed extrinsic compression characterized by an extrinsic pressure-type bulge on the posterior wall of the hypopharynx; B: Cervical computed tomography demonstrated multiple bony bridges at the margins of the cervical and thoracic vertebrae.

Figure 3 Imaging examinations. A: Case 1: Postoperative imaging examinations indicated complete removal of the hyperplastic bone at the anterior edge of the C3/4 vertebral bodies; B: Case 1: Nasopharyngoscopy before (left) and after (right) surgery illustrated the resolution of the extrinsic compression/bulge on the posterior pharyngeal wall; C: Case 2: Postoperative imaging performed after 1 year revealed the resolution of the cervical and thoracic vertebral osteophytes.
