Summary

The aim of this project is to perform a detailed evaluation of upper esophageal sphincter function and the swallowing mechanism in patients with swallowing disorders or suspected extraesophageal reflux using high-resolution manometry with impedance and 24-hour pH-impedance monitoring.

Detailed description

The project seeks to improve diagnostic accuracy, identify functional abnormalities that are not detectable by conventional diagnostic methods, and establish a foundation for more effective and targeted therapeutic strategies. The upper esophageal sphincter (UES) represents a crucial functional structure at the junction of the digestive and respiratory tracts. Its proper function is essential for the coordination of the swallowing process and for the protection of the upper airways. Disorders of the UES may be associated with a wide range of otorhinolaryngological symptoms, including dysphagia, globus pharyngeus, chronic cough, hoarseness, laryngeal dysfunction, and voice disorders. Modern diagnostic techniques, such as 24-hour esophageal impedance monitoring and high-resolution manometry (HRM), enable detailed assessment of gastroesophageal reflux and esophageal pressure dynamics, thereby offering new possibilities for the diagnosis and understanding of these conditions.

Conditions

• Extraesophageal Reflux
• Laryngopharyngeal Reflux
• Dysphagia
• Chronic Cough
