Key Words	Sagittal alignment; Occipitocervical fusion; Craniocervical disorders; Cervical spine; Dysphagia
Core Tip	Patients with craniocervical junction disorders had a more kyphotic upper cervical sagittal alignment (CSA) and a more lordotic lower CSA than normal controls: The decreased lordosis of the upper cervical spine caused by the weakness of paraspinal muscles and ligaments (OC2a↓) lead to the gravity center of cranium moving forward (C2Ta↑). To maintain horizontal gaze and normal C2-7 sagittal vertical axis, the lordosis of the lower cervical spine was increased (C2-7a↑). Moreover, the restoration of CSA after occipitocervical fusion (OCF) may be limited by neglecting the realignment of craniocervical junction. The reduction of the O-C2a after OCF would increase the C2-7a and decrease the pharyngeal inlet angle and lead to postoperative dysphagia.
