sväljningsstudie

A sväljningsstudie, also known as a swallowing study or dysphagia evaluation, is a diagnostic procedure used to assess the function of the swallowing mechanism. It helps identify problems that may interfere with the safe and efficient passage of food and liquid from the mouth to the stomach. These studies are crucial for individuals experiencing difficulties with swallowing, a condition known as dysphagia.

There are various types of sväljningsstudie. One common method is the videofluoroscopic swallow study (VFSS), also called a modified barium swallow. This involves a patient swallowing a contrast material containing barium, which is visible on X-ray. Real-time X-ray images are recorded, allowing clinicians to observe the movement of the bolus through the pharynx and esophagus. Another type is the fiberoptic endoscopic evaluation of swallowing (FEES), which uses a small camera inserted through the nose to visualize the pharynx and larynx during swallowing. This allows for direct observation of vocal cord movement and airway protection.

Swallowing studies can reveal a range of issues, including problems with oral preparation of the bolus, delayed swallow initiation, inadequate pharyngeal constriction, reduced laryngeal elevation, or aspiration, where food or liquid enters the airway. The results of a sväljningsstudie guide the development of personalized treatment plans, which may include dietary modifications, swallowing exercises, or compensatory strategies to improve safety and quality of life for individuals with dysphagia.
