Are there Still any Benefits to Drainage for Anterior Cervical Arthrodesis/Arthroplasty by Cervicotomy?

Study design. A retrospective single-center study between January 2019 and 2023. Objective. The role and contribution of drainage in the anterior approach to the cervical spine (cervicotomy) is much debated, motivated primarily by the prevention of retropharyngeal hematoma, so are there still any benefits to drainage? Background. The anterior approach to the cervical spine is a widespread and common procedure performed in almost all spine surgery departments for the replacement of cervical intervertebral discs and medullar or radicular decompression. The primary endpoint was the occurrence of symptomatic postoperative cervical hematoma. Methods. Four hundred thirty-one patients who had undergone cervical spine surgery by anterior cervicotomy for cervicarthrosis or cervical disc herniation (ACDF, ACDR) were consecutively included. Patients were separated into 2 groups: Group A, 140 patients (with postoperative drainage) and group B, 291 patients (without drainage). Results. Mean follow-up was 2.8 months. The 2 groups were comparable on all criteria, but there was a predominance of arthroplasty ( P <0.0001), use of anticoagulants/antiaggregants ( P <0.0001) and a greater number of stages ( P <0.0001) in group A. There were a total of 4/431 symptomatic postoperative hematomas (0.92%) in this study. Two hematomas occurred in group A (2/140, 1.4%) and two in group B (2/291, 0.68%) ( P <0.0001). One patient in group A (0.71%) required surgical drainage for cavity hematoma revealed by marked dyspnea, swallowing and neurological disorders. One case of hematoma diagnosed by dysphonia and neurological deficit was reported in group B (0.34% ( P <0.0001). Conclusions. Placement of a drain during anterior cervicotomy for (ACDF/ACDR) did not limit the occurrence of symptomatic postoperative hematoma.
