36. Table-mounted Versus Self-retaining Retraction: An Assessment of Postoperative Dysphagia Following Anterior Cervical Spine Surgery.

Abstract

Study Design: Retrospective study., Objective: To determine whether there are significant differences in postoperative dysphagia when using table-mounted versus self-retaining retractor tools., Summary of Background Data: Retraction of prevertebral structures during anterior cervical spine surgery (ACSS) is commonly associated with postoperative dysphagia or dysphonia. Retractors commonly used include nonfixed self-retaining retraction devices or fixed table-mounted retractor arms. However, there is a paucity of literature regarding differences in dysphagia between retractor types., Methods: Patients who underwent ACSS and adhered to a minimum of 6-month follow-up were retrospectively evaluated. Patient-reported outcomes (PROs) were compared between table-mounted and self-retaining retractor groups at the preoperative and final postoperative time points, including the SWAL-QOL survey for dysphagia. Categorical dysphagia was assessed using previously defined values for the minimum clinically important difference (MCID)., Results: Overall, 117 and 75 patients received self-retaining or table-mounted retraction. Average follow-up was significantly longer in the self-retaining cohort (14.8±15.0 mo) than in the table-mounted group (9.4±7.8, P=0.005). No differences were detected in swallowing function (P=0.918) or operative time (P=0.436), although 3-level procedures were significantly shortened with table-mounted retraction (P=0.005). Multivariate analysis trended toward worse swallow function with increased operative levels (P=0.072) and increased retraction time (P=0.054), although the retractor used did not predict swallowing function (P=0.759). However, categorical rates of postoperative dysphagia were lower with table-mounted retraction (13.3% vs. 27.4%, P=0.033)., Conclusions: There was no significant difference observed in long-term swallowing dysfunction between patients who underwent ACSS with self-retaining and table-mounted retractors, although the rate of dysphagia was lower with table-mounted retraction. In addition, the greater number of operated levels per case in the table-mounted group at a similar time suggests improved efficiency., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.
