Introduction:

Cervical spine surgery (anterior cervical spine surgery [ACSS]) is a commonly indicated to provide neurological decompression, correct deformity, and preserve stability. Current series report good to excellent results, but a number of patients suffer from dysphagia with reported rates as high as 80%.

Materials and methods:

Retrospective cohort of patients undergoing ACSS (anterior cervical discectomy and fusion [ACDF]; and arthroplasty, total disc replacement [TDR]) from 2013 to 2017 by a single surgeon. We collected demographic data, surgical outcomes, clinical outcomes, and dysphagia incidence and magnitude (visual analog scale [VAS]), we analyzed results with SPSS 22.

Results:

A total of 81 patients operated from 2013 to 2018, ACDF was performed in 70, and TDR was performed in 11, mean surgical time was 156.8, mean neck pain and radicular pain VAS reduced significantly in both groups (p < 0.01). Dysphagia was encountered in 18 ACDF patients, and one TDR patient. Overall dysphagia rate was 9.1% in day-1 post-operative, with mean 0.27 magnitude (standard deviation [SD] 0.4) in ACDF group and 0.18 (0.6 SD) in TDR group, 1-month follow-up dysphagia rate was 0%.

Conclusions:

Minimally invasive techniques may reduce post-operative dysphagia related to soft-tissue trauma, to 9% in day-1 post-operative (as compared to 39%), and to 0% (as compared to 8.5% reported worldwide) by 1-month follow-up.
