Upper esophageal sphincter (UES) dysfunction occurs when the muscles of the upper esophagus, specifically the cricopharyngeus, develop impaired relaxation. Symptoms include progressive dysphagia from pills to solids and then liquids. Diagnosis is made from a thorough history and Modified Barium Swallow Study (MBSS).

The modified barium swallow study (MBSS) is a widely used videofluoroscopic evaluation of the functional anatomy and physiology of swallowing that permits visualization of bolus flow throughout the upper aerodigestive tract in real time.

A Modified Barium Swallow Study (MBSS) is a special x-ray that allows the Radiologist (who specializes in using x-rays) and Speech Language Pathologist (SLP) to identify why you are having trouble swallowing. The SLP is a professional who specializes in the diagnosis and treatment of swallowing disorders and communication problems.

2018年7月1日 · Many studies have reported the swallowing exercise for the UES dysfunction, this systematic review aims to appraise the evidence of the swallowing exercise to facilitate the suprahyoid muscle and open the UES for stroke patients with dysphagia.

2019年9月25日 · The modified barium swallow study (MBSS), a real-time fluoroscopic motion study, is the reference standard to assess swallowing physiology involving the oropharynx and esophagus.

Systematic Approach to Reading an MBSS Understand the study protocol Look at the pre‐swallow lateral fluoroscopic view Look at each swallow and evaluate the 4 phases of swallow Frame to frame analysis on swallows with issues of efficiency and safety to understand why

2024年3月5日 · The MBSS is indicated for known or suspected oropharyngeal dysphagia. The updated ACR-SPR MBSS Practice Parameter lists 20 indications for the MBSS, up from 15 in the prior version.

Under normal circumstances, the upper esophageal sphincter (UES) serves as an important gatekeeper, regulating antegrade and retrograde bolus movement through the upper aerodigestive tract. Dysfunction of the UES can result in multiple distressing symptoms and serious complications; accurate diagnosis is critical to appropriate management.

2006年5月16日 · At rest, closure of the upper esophageal sphincter (UES) is due to passive forces as well as active muscle contraction, and its relaxation requires inhibition of...

Manometry of the pharynx and the upper esophageal sphincter (UES) provides important information on the swallowing mechanism, especially about details on the pharyngeal contraction and relaxation of the UES. However, UES manometry is challenging ...
