Summary

This study tracks how often swallowing difficulties (dysphagia) and voice changes (dysphonia) happen after anterior cervical spine surgery — a common procedure to treat a narrow spinal canal. Researchers will follow 36 patients for one year after surgery, using questionnaires and a camera test that looks at the throat during swallowing. The goal is to better understand these complications and help improve recovery.
