Swallowing indicates the transmission of fluid boluses from the pharynx (velopharynx, oropharynx, and hypopharynx) through the upper esophageal sphincter (UES). Abnormal swallowing can reveal fluid accumulation at the pharynx, which increased the aspiration risk. However, objective evidence is limited. High-resolution impedance manometry (HRIM) was applied for an objective swallowing evaluation for a more detailed analysis. We aimed to elucidate whether HRIM can be used to detect perioperative swallowing changes in patients undergoing ACSS.enanterior cervical spine surgery; high-resolution impedance manometry; hypopharynx; perioperative swallowing physiology; upper esophageal sphincterjournal article10.3389/fsurg.2022.851126353724732-s2.0-85127510610WOS:000784348200001https://scholars.lib.ntu.edu.tw/handle/123456789/604266
