Using the High Resolution Impedance Manometry to Evaluate Swallowing Function After Cervical Spine Surgery

2019-10-17 11:03:48 | BioPortfolio

Summary

Dysphagia is a well-known complication following cervical spine surgery, including anterior or posterior approach. However, which muscle at oropharyngeal region weakness and the recovery course of these patients are still unknown.

The high resolution impedance manometry (HRIM) could be used to measure the postoperative recovery esophageal function.

Description

Dysphagia is a well-known complication following cervical spine surgery, including anterior or posterior approach. However, which muscle at oropharyngeal region weakness and the recovery course of these patients are still unknown.

The high resolution impedance manometry (HRIM) could be used to measure the postoperative recovery esophageal function.

In this study, using the high resolution impedance manometry to determine (1) whether the occurrence of dysphagia in the postoperative 1 or 7 days and 1 month in the patients receiving anterior vs posterior approach of cervical spine surgery (2) which muscle in the pharyngeal region would be destroyed Consecutive patients who will fulfill the criteria of cervical spine surgery patients under general anesthesia and aged >= 20 will be enrolled. The patients would receive the dysphagia questionnaire. All subjects would receive the swallowing function by HRIM before the surgeries. The cough test was also measured. After the surgery, the patient would be followed the swallowing function in the postoperative one day, and 1 week by HRIM and questionnaire.

This study would expect (1) that the posterior cervical spine surgery would result in dysphagia greater than baseline, but less than that of anterior cervical procedures; (2) decreasing upper esophageal sphincter (UES) pressure may be the reason of postoperative dysphagia in the anterior cervical spine surgery, resulted from the intraoperative traction; (3) decreasing hypopharyngeal muscle pressure may be the reason of postoperative dysphagia in the posterior spine surgery, resulted from the prone and flexion positioning.

Medical and Biotech [MESH] Definitions

Inflammation of the anterior uvea comprising the iris, angle structures, and the ciliary body. Manifestations of this disorder include ciliary injection, exudation into the anterior chamber, iris changes, and adhesions between the iris and lens (posterior synechiae). Intraocular pressure may be increased or reduced.

The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung. (From Best & Taylor's Physiological Basis of Medical Practice, 12th ed, p562)

The compartment containing the anterior extremities and half the inferior surface of the temporal lobes (TEMPORAL LOBE) of the cerebral hemispheres. Lying posterior and inferior to the anterior cranial fossa (CRANIAL FOSSA, ANTERIOR), it is formed by part of the TEMPORAL BONE and SPHENOID BONE. It is separated from the posterior cranial fossa (CRANIAL FOSSA, POSTERIOR) by crests formed by the superior borders of the petrous parts of the temporal bones.

A polygonal anastomosis at the base of the brain formed by the internal carotid (CAROTID ARTERY, INTERNAL), proximal parts of the anterior, middle, and posterior cerebral arteries (ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; POSTERIOR CEREBRAL ARTERY), the anterior communicating artery and the posterior communicating arteries.

Two extensive fibrous bands running the length of the vertebral column. The anterior longitudinal ligament (ligamentum longitudinale anterius; lacertus medius) interconnects the anterior surfaces of the vertebral bodies; the posterior longitudinal ligament (ligamentum longitudinale posterius) interconnects the posterior surfaces. The commonest clinical consideration is OSSIFICATION OF POSTERIOR LONGITUDINAL LIGAMENT. (From Stedman, 25th ed)
