Radiographic presentation of an atlantoaxial dislocation patient suffering postoperative dysphagia. a The preoperative values of O-EAa and O-C2a were 111.2° and − 5.2°, respectively, and nPAS was 0.64 cm. bThe preoperative values of C2-7a and PIA were 88.6° and 42.7°, respectively. ADI was 0.60 cm. c and d Postoperative measurement of radiographic parameters. On postoperative measurements, O-EAa, O-C2a and C2-7a decreased to 94.5°, -9.9° and 33.6°, respectively, and PIA decreased to 80.9°. Atlantoaxial reduction was achieved. The oropharyngeal space decreased significantly to 0.47 cm and experienced postoperative dysphagia
