Front-of-neck approaches for anterior cervical spine surgery and swallowing problems

Anterior Cervical Spine Strap Muscle Splitting Versus Smith-Robinson Approach: A Single-Centre Observational Study

Hamilton Health Sciences Corporation · NCT07533864

This will see if the Smith-Robinson or strap-splitting front-of-neck approach causes fewer swallowing or voice problems for adults having anterior cervical spine surgery.

What this trial studies

This observational study compares swallowing and voice complications after two front-of-neck approaches for anterior cervical spine surgery: the Smith-Robinson approach versus the strap-splitting approach. Patients receive one of the two approaches based on surgeon preference as part of routine care and complete the HSS-DDI questionnaire in English to report swallowing symptoms. The study enrolls adults undergoing ACDF, anterior cervical arthroplasty, or ACCF and excludes revision anterior surgery, planned anterior odontoid screws, and trauma patients. Data are collected at Hamilton General Hospital to compare rates and severity of dysphagia and voice changes between the two techniques.

Who should consider this trial

Good fit: Adults (18+) scheduled for primary anterior cervical procedures (ACDF, ACA, or ACCF) who can complete the HSS-DDI questionnaire in English are ideal candidates.

Not a fit: Patients undergoing revision anterior surgery, planned anterior odontoid screw placement, or surgery for trauma are excluded and would not be represented by the results.

Why it matters

Potential benefit: If successful, the results could help surgeons choose the approach that reduces swallowing and voice complications, improving recovery and quality of life after surgery.

How similar studies have performed: Prior surgical series and observational studies have reported dysphagia and voice complication rates after different anterior cervical techniques, but findings are mixed and high-quality comparative data are limited.
