Structural Oropharyngeal Dysphagia

Structural oropharyngeal dysphagia is a condition that affects a person’s ability to swallow food and liquids comfortably and safely due to physical abnormalities in the mouth and throat. In this article, we’ll break down the key aspects of structural oropharyngeal dysphagia in simple, easy-to-understand language. We’ll cover types, causes, symptoms, diagnostic tests, treatments, and relevant medications.

Types of Structural Oropharyngeal Dysphagia

1. Oral Dysphagia: This type of dysphagia involves difficulties in the mouth, such as problems with chewing or forming a cohesive food bolus for swallowing.
2. Pharyngeal Dysphagia: Pharyngeal dysphagia occurs when there are issues with the swallowing reflex in the throat, which can lead to choking or aspiration.
3. Esophageal Dysphagia: This type of dysphagia relates to difficulties in the esophagus, which is the tube connecting the throat to the stomach. It can cause pain or discomfort during swallowing.

Causes of Structural Oropharyngeal Dysphagia

1. Stroke: Damage to the brain can affect the control of the muscles involved in swallowing.
2. Neurological Disorders: Conditions like Parkinson’s disease and multiple sclerosis can disrupt the coordination of swallowing muscles.
3. Head and Neck Cancer: Tumors in the mouth or throat can obstruct the swallowing passage.
4. Cleft Palate: A congenital condition where there is an opening in the roof of the mouth can make it hard to form a proper seal for swallowing.
5. Muscle Weakness: Conditions like myasthenia gravis weaken the muscles needed for swallowing.
6. Inflammation: Infections or inflammation in the throat or esophagus can make swallowing painful and difficult.
7. Gastroesophageal Reflux Disease (GERD): Chronic acid reflux can damage the esophagus and lead to dysphagia.
8. Radiation Therapy: Treatment for head and neck cancer may damage the tissues involved in swallowing.
9. Achalasia: A rare disorder where the lower esophageal sphincter doesn’t relax properly, causing difficulty in food passage.
10. Zenker’s Diverticulum: A pouch-like bulge in the throat can trap food and cause swallowing problems.
11. Trauma: Injury to the mouth or throat from accidents can result in structural damage affecting swallowing.
12. Scar Tissue: Surgical procedures in the neck or esophagus can lead to the formation of scar tissue, causing narrowing.
13. Foreign Bodies: Swallowing objects that get stuck in the throat or esophagus can cause dysphagia.
14. Systemic Sclerosis: A rare autoimmune disease that can affect the esophagus, leading to swallowing difficulties.
15. Aging: As we age, the muscles involved in swallowing can weaken, leading to dysphagia.
16. Medications: Certain drugs can cause dry mouth or throat irritation, making swallowing harder.
17. Nutritional Deficiencies: Lack of essential nutrients can weaken the muscles needed for swallowing.
18. Alcohol and Substance Abuse: Long-term abuse can damage the throat and lead to dysphagia.
19. Anxiety and Stress: Psychological factors can contribute to swallowing difficulties.
20. Psychogenic Dysphagia: A psychological aversion to swallowing, unrelated to physical issues, can lead to dysphagia.

7. Recurrent Pneumonia: Aspiration of food or liquids into the lungs.
8. Food Pocketing: Food remaining in the mouth after swallowing attempts.
9. Fatigue: Feeling tired after eating due to the extra effort required to swallow.
10. Bad Breath: Caused by food particles staying in the mouth or throat.
11. Dehydration: Difficulty in drinking enough fluids.
12. Avoidance of Certain Foods: Avoiding specific textures or consistencies of food.
13. Sensation of Food Stuck: Feeling like food is stuck in the throat or chest.
14. Increased Mealtime Duration: Taking longer to finish meals.
15. Gurgling or Noisy Swallowing: Audible sounds during swallowing.
16. Wet or Gurgly Voice: Voice changes due to saliva pooling.
17. Painful Swallowing: Sharp or burning pain with swallowing.
18. Frequent Respiratory Infections: Due to aspiration of food or liquids.
19. Difficulty Swallowing Pills: Trouble swallowing solid medications.
20. Social Isolation: Avoiding social situations involving food due to embarrassment.

Diagnostic Tests for Structural Oropharyngeal Dysphagia

1. Barium Swallow Test: A special X-ray to visualize the swallowing process using a contrast material.
2. Endoscopy: A thin, flexible tube with a camera is inserted into the throat to examine the structures.
3. Video Fluoroscopic Swallow Study (VFSS): Real-time X-ray imaging during swallowing.
4. Fiber-optic Endoscopic Evaluation of Swallowing (FEES): A flexible scope with a camera to assess swallowing.
5. Manometry: Measures pressure in the esophagus and throat during swallowing.
6. CT Scan or MRI: Imaging to detect structural abnormalities.
7. Esophageal pH Monitoring: Measures acid levels in the esophagus to diagnose GERD.
8. Electromyography (EMG): Records electrical activity in swallowing muscles.
9. Blood Tests: To rule out underlying medical conditions.
10. Biopsy: Taking a small tissue sample for examination.
11. Sensory Testing: Evaluates sensitivity in the throat.
12. Saliva Swallow Test: Measures the ability to swallow saliva.
13. Video Nasendoscopy: Visualizes the throat and vocal cords during swallowing.
14. Modified Barium Swallow (MBS): A variation of the barium swallow test with different consistencies of food and liquid.
15. Cervical Auscultation: Listening with a stethoscope to detect abnormal sounds during swallowing.
16. Ultrasound: Imaging using sound waves to examine the throat.
17. Esophageal Manometry: Measures pressure and muscle contractions in the esophagus.
