Thumping at the laryngeal node when swallowing saliva may be related to gas-over-water effect and pharyngo-esophageal diverticulum.
1. Gas-over-water effect: Normal epiglottis valley, pyriform fossa and other pharyngeal interstitial space contains a small amount of gas, in swallowing, saliva with the gas downstream can produce mucus tension breaks after the burst sound, similar to the thumping sound.
2. Pharyngo-esophageal diverticulum: Because there is a weak triangle between the hypopharyngeal contraction muscle and the cricopharyngeal muscle, coupled with the incoordination of the muscle activity, that is, when the hypopharyngeal contraction muscle contraction of the food downward push, the cricopharyngeal muscle does not relax or premature contraction, resulting in the mucous membrane of the esophagus from the weak area of the dilatation, which is a dilatation-type pseudo-diverticulum. When the diverticulum enlarges, there are gurgling and thumping sounds during swallowing.
When you find that there is often a thumping sound at the laryngeal node when swallowing, you can actively seek medical treatment and systematic examination to clarify the diagnosis and cause of the disease.
