What can ultrasound be used to observe in relation to dysphagia?
Ultrasound can be used to observe tongue function, measure oral transit times, and assess the motion of the hyoid bone.
-
What are some limitations of ultrasound in imaging studies for dysphagia?
Ultrasound is unable to visualize the pharynx due to the presence of mixed tissue types, limiting its ability to provide a complete assessment of the swallowing process.
-
What is the history of videofluoroscopy in relation to dysphagia assessment?
Videofluoroscopy was developed in the 1930s and allowed for the examination of the oral cavity, pharynx, and esophagus during swallowing. The use of movie film known as cinefluorography enabled slow-motion and frame-by-frame viewing of the fluoroscopic image.
-
What are some disadvantages or limitations of videofluoroscopy?
Videofluoroscopy requires higher radiation exposure compared to other imaging methods, and the results are not immediately available for viewing.
-
What is the recent advancement in videofluoroscopy?
In recent years, videofluoroscopy studies have been recorded on video, allowing for better analysis and playback of the swallowing process. This feature is particularly important since the swallow occurs very quickly, typically lasting only 1-2 seconds.
-
What information can be obtained through videofluoroscopy?
Videofluoroscopy provides valuable information about the swallowing process, including bolus transit times, motility problems, and the amount and cause of aspiration. It allows for the visualization of the movement and coordination of the structures involved in swallowing, helping to identify any abnormalities or difficulties in the swallowing function.
-
What are the advantages of videofluoroscopy in assessing swallowing disorders?
Videofluoroscopy offers several benefits in the evaluation of swallowing disorders. It allows for the visualization of various aspects of the swallowing process, including mastication and the oral stage, the triggering of the pharyngeal swallow, and the motor aspects of the pharyngeal swallow. This provides valuable information about the coordination and movement of structures involved in swallowing. Additionally, videofluoroscopy can assess the effectiveness of treatment strategies, helping clinicians make informed decisions about intervention approaches. Another advantage is the ability to view the swallow from lateral and posterior-anterior perspectives, providing a comprehensive assessment of swallowing function.

What are the advantages of using Videoendoscopy (FEES) for assessing swallowing disorders?
It allows for the examination of the anatomy of the oral cavity, pharynx, and larynx before and after the swallow.It enables the examination of the dynamics of velopharyngeal (VP) closure.
-
What are the limitations of Videoendoscopy (FEES) as an imaging study for swallowing disorders?
It cannot view the oral stage of the swallow.
It cannot view the swallow in real-time.
It can pose difficulties in defining the nature of physiological disorders and determining the effectiveness of treatment techniques.
-
What is Scintigraphy?
Scintigraphy is a nuclear medicine test where patients swallow measured amounts of radioactive material, and during the swallow, the bolus is imaged and recorded by a gamma camera.
-
What are the pros of Scintigraphy?
It allows for the measurement of the amount of aspiration and residue during swallowing.
It is diagnostic for esophageal aspects of swallowing disorders, such as gastroesophageal reflux disease (GERD).
It is helpful for research purposes.
-
What are the cons of Scintigraphy?
It exposes the patient to radiation.
It has limited visualization of anatomical structures involved in swallowing.
It may have difficulty in assessing certain aspects of swallowing function.
It requires specialized equipment and expertise.
-
What are the cons of Scintigraphy?
The physiology of the oral cavity and pharynx is not visualized during the test.
It is unable to identify disorders that cause residue and aspiration.
-
What is the purpose of Electromyography (EMG) in the evaluation of dysphagia?
Electromyography (EMG) can provide information on the timing and relative amplitude of muscle contractions during swallowing. It is also used as a biofeedback technique for dysphagia therapy.
-
What is the purpose of Electroglottography in the evaluation and treatment of dysphagia?
Electroglottography is used to track the movement of the vocal folds by recording impedance changes as they move during phonation. It can also track laryngeal elevation and provide biofeedback for treatment purposes in dysphagia.
-
What is the purpose of cervical auscultation in the evaluation of swallowing and respiration
Cervical auscultation is used to assess swallowing and respiration. For swallowing, it involves using acoustics parameters such as a small microphone, accelerometer, or a stethoscope to detect specific sounds during the swallow, such as the "click" of the opening of the eustachian tube and the "clunk" of the opening of the upper esophageal sphincter (UES). For respiration, cervical auscultation helps define the inhalatory and exhalatory phases and determines the phase in which the pharyngeal swallow occurs. It can also assess secretion levels before and after the swallow.
-
What can be measured using pharyngeal manometry in the evaluation of swallowing?
Pharyngeal manometry is a technique used to measure various aspects of swallowing. It can measure pressure changes during the pharyngeal swallow, providing information about the coordination and strength of muscle contractions involved in swallowing. It can also measure intrabolus pressures, which helps assess the pressure exerted on the bolus during swallowing. Pharyngeal manometry is also used to measure the pharyngeal contractile wave, which is the coordinated movement of the pharyngeal muscles during swallowing. Additionally, it provides an indirect examination of the relaxation of the cricopharyngeus muscle, which is important for the opening and closing of the upper esophageal sphincter.
