Abstract:
Occipitocervical fusion (OCF) is used to treat the instability of the cranio-cervical junction due to various reasons (such as trauma, rheumatoid arthritis, infection, tumor, congenital malformations and degeneration). A satisfactory fusion rate can be obtained and the stability of the occipital neck can be reconstructed by OCF. Dysphagia is one of the most common complications after OCF, which seriously affects the quality of life of patients after surgery. This article mainly focuses on the evaluation and prediction methods of dysphagia after OCF, and summarizes related research in the past 16 years, and provides guidance and direction for how to predict the occurrence of dysphagia during OCF and the evaluation of postoperative dysphagia. The evaluation of dysphagia is mainly conducted using the Bazaz dysphagia score, swallowing quality of life scale (SWAL-QOL) and eating assessment tool-10 (EAT-10) score. However, the clinical prediction of dysphagia is mainly based on the changes of cervical curvature parameters (O-C 2 angle, O-EA angle, Oc-Ax angle, PI angle). At present, there are many methods for clinical evaluation and prediction of dysphagia, but the best evaluation method is still uncertain. We reviews the evaluation and prediction methods of postoperative dysphagia of OCF, showing that the Bazaz dysphagia score, SWAL-QOL score and EAT-10 score scale are suitable for evaluating postoperative dysphagia of OCF. During OCF operation, adjustment of O-C 2 Angle >-5°, O-EA Angle >100°, Oc-Ax Angle >65°, and increase of postoperative PI Angle from preoperative PI Angle (that is, dPI Angle) ≥0° can reduce the probability of dysphagia to a certain extent.
