Swallowing Evaluation by HRIM in Patients With Cervical Spondylosis

Using High Resolution Impedance Manometry and Videofluoroscopic Measurements of Swallowing Function in Patients Undergoing Cervical Spine Patients

patients with cervical spondylolysis may have swallowing or eating difficulty. In this study, we will use high resolution impedance manometry to evaluate these patients' detailed swallowing mechanisms.

This study will aim to evaluate swallowing function in patients with cervical spondylolysis by using high resolution impedance manometry (HRIM) along with oral frailty and dysphagia questionnaires. Researchers will plan to enroll 50 patients to investigate this issue. The inclusion criteria will be as following:1) age higher or equal to 20 years old; 2) patients with cervical spondylolysis or associated symptoms. The exclusion criteria will be as following: major organ dysfunction, including chronic kidney disease, bleeding tendency. The primary outcome will be the upper esophageal sphincter relaxing pressure. The researchers will hope to find the swallowing dysfunction mechanisms in these patients.

Inclusion Criteria:

• patients with cervical spondylosis associated symptoms or expected to undergo cervical spine surgery
• patients with associated swallowing difficulty symptoms

Exclusion Criteria:

• major organ dysfunction, such as renal insufficiency or bleeding tendency
