We report a rare case of dysphagia after occipitocervical fixation, and aim to emphasize the importance of occiput-C2 angle. The kyphotic change of occiput-C2 alignment after operation might lead to dysphagia due to decreased oropharyngeal cross-section area and increased basal pressure of upper esophageal sphincter. Carefully align the occiput-C2 angle during occipitocervical fixation might reduce the incidence of postoperative dysphagia.
我们报告了一例罕见的枕颈固定术后吞咽困难病例，旨在强调枕骨-C2 角的重要性。术后枕骨-C2 对线的后凸变化可能导致吞咽困难，原因是口咽横截面积减小和上食管括约肌基础压增高。在枕颈固定时仔细调整枕骨-C2 角可能会降低术后吞咽困难的发生率。
