Dysphagia May Attenuate Improvements in Postoperative Outcomes Following Anterior Cervical Discectomy and Fusion

Abstract

Background: Past studies outline potential risk factors for dysphagia following anterior cervical discectomy and fusion (ACDF). Few studies explored the impact of dysphagia, as measured by the swallowing quality of life (SWAL-QOL), on postoperative patient-reported outcome measure (PROM) improvement. This study aimed to determine the relationship between dysphagia and improvement in pain, disability, physical function, and mental health following ACDF.Methods: A retrospective review of patients undergoing primary 1-or 2-level ACDF was performed. Individuals without a completed preoperative SWAL-QOL were excluded. Outcomes were collected for visual analog scale (VAS) neck and arm pain, Neck Disability Index (NDI), Patient-Reported Outcome Measurement Information System Physical Function (PROMIS-PF), 12-Item Short Form Physical Component Score (SF-12 PCS), 9-Item Patient Health Questionnaire (PHQ-9), and SWAL-QOL. Postoperative improvement from preoperative values was evaluated using a paired t test. The impact of SWAL-QOL on each PROM was assessed using linear regression.Results: A total of 91 patients were included. Mean preoperative SWAL-QoL was 90.4, which worsened at 6 weeks and resolved by 6 months (P ≤ 0.007, both). VAS neck and arm scores significantly improved postoperatively (P < 0.001), as did the NDI score (P < 0.001). Physical function significantly improved at 12 weeks and 6 months (P ≤ 0.021, both). Depressive symptoms improved at 6 weeks and 12 weeks (P ≤ 0.007, both). Preoperatively, SWAL-QOL demonstrated significant relationships with all PROMs (P ≤ 0.005, all). At 6 weeks, 12 weeks, and 6 months (P ≤ 0.048, all), SWAL-QoL again demonstrated a similar significant association with all PROMs. Multiple regression did not demonstrate common demographic or operative variables that were significant predictors of PROMs.Conclusion: Following ACDF, patients experienced a worsening of dysphagia but resolved by 12 weeks. All PROMs demonstrated significant improvements by the 6-month timepoint, except for PHQ-9. SWAL-QoL demonstrated a significant effect on all postoperative outcomes, which may suggest that this questionnaire could effectively evaluate dysphagia and predict positive or negative outcomes following ACDF.Level of Evidence: 3 Clinical Relevance: The severity of dysphagia has a significant association with pain, disability, mental health, and physical function patient-reported outcome measures in patients undergoing ACDF.

The Role of Psychosomatic Traits in Tailored Workup for Anterior Cervical Discectomy and Fusion—A Case Series

“…Anterior cervical discectomy and fusion (ACDF) is a cornerstone procedure for managing degenerative and traumatic cervical spine conditions [1]. Several factors have been shown to be predictors for ACDF success in treating myelopathy or radiculopathy, such as smoking habits [2], postoperative dysphagia [3], preoperative disability and pain level, gender, cervical spine sagittal profile [4], cage design and material, subsidence, pseudoarthrosis [5], and the active range of motion (ROM) [6]. Psychological elements, like maladaptive coping strategies and psychiatric comorbidity, may contribute to the persistence of pain and have often been overlooked.…”

Does Operative Level Impact Dysphagia Severity After Anterior Cervical Discectomy and Fusion?

“…Symptoms are often transient and generally resolve after observation or conservative treatment without substantial impact on patient satisfaction or overall surgical outcomes 1,4 . However, severe cases can have debilitating short-or long-term impacts on comfort, daily function, dietary intake, and quality of life 5,6 . This potential has triggered an extensive investigation into the varying aspects of the pre and postoperative courses in patients who experience dysphagia in the perioperative period.…”
