OBJECTIVES: This study aimed to quantify the effects of head rotation on upper esophageal sphincter (UES) pressure in healthy subjects using a novel high-resolution manometry (HRM) system. STUDY DESIGN: Prospective study. SETTING: Nagasaki University Hospital. SUBJECTS AND METHODS: Eighteen asymptomatic Japanese male adult volunteers were studied. A solid-state HRM was positioned to record resting UES pressure. After endoscopically confirming on which side of the pyriform sinus the manometric sensor was positioned within the hypopharynx, we measured the maximum and mean values of the resting UES pressure and the length of the zone of the UES along the esophagus with the patients in the following positions: 1) neutral and straightforward head position (NSF), 2) turning the head in the direction of the side in which the sensor was positioned (HSS), and 3) turning the head in the opposite direction of the side with sensor (HOS). RESULTS: The maximum and mean values of the resting UES pressure were statistically higher in HSS than in NSF (P = 0.0001 and P < 0.0001, respectively), and were statistically lower in HOS than in NSF (P < 0.0001 and P < 0.0001, respectively). The length of the zone of the UES was statistically shorter in HOS than in NSF (P < 0.0001), but there was no significant difference in resting UES pressure along the esophagus between HSS and NSF (P = 0.3024). CONCLUSION: The present study provided us with physiological information regarding normal UES pressure in relation to head rotation. This data will be of aid to future clinical and investigative swallowing studies. Additionally, the current study provides evidence of the safety and usefulness of the head rotation maneuver for dysphagic patients. |
