Because such findings are so common in the general population, it has become clear that almost everyone occasionally experiences some reflux. Reflux-related irritation causes redness and swelling of the larynx, especially the parts close to the esophagus at the back of the vocal folds. Reflux may be only one part of a combination of factors contributing to the same constellation of symptoms. It is important to understand that the presence of the above symptoms does not necessarily mean that reflux is the main cause or even involved at all. During both of these actions, the vocal folds collide violently, and over time the chances of damage increase. People with reflux irritation typically cough and clear their throats constantly. More severe reflux can cause throat pain and laryngospasm, a sudden involuntary closure of the vocal folds that makes it difficult to breathe for a few moments. Swallowing, particularly of dry solids, can become difficult. Sometimes, an accompanying sensation, of tickling or pricking that triggers throat clearing or coughing, is present. In fact, reflux is more common than irritation from nasal discharge. This has caused many to attribute the symptoms of reflux to “post-nasal drip”, a term with more meaning in advertising than in medicine. This can make it feel as if there is a mass or mucus in the throat. Reflux causes irritation and swelling of the larynx. Severe redness and swelling of the vocal folds from a combination of smoking and reflux What are the symptoms of reflux? Ongoing research investigates reflux as a factor that compounds the effects of phonotrauma and smoking, and contributes to respiratory difficulties like asthma. It is a major factor in the formation of vocal fold granuloma. Irritation from reflux causes symptoms by itself, as well as contributing to other problems. This may account for the phenomenon of “silent reflux”: reflux-related irritation in the throat without the more typical symptoms like heartburn or chest discomfort. The larynx is not as well protected as tissues closer to the stomach, and thus, it has the potential to be more damaged by contact with stomach fluid. Reflux is significant because the acid and enzymes that reach the larynx can cause injury and irritation. This is the same process that causes gastroesophageal reflux disease, or GERD, except that otolaryngologists are preoccupied with its effects at the level of the larynx, instead of the esophagus. D igestive acid and enzymes flow upward from the stomach through the esophagus to the level of the vocal folds. Reflux is short for “reflux laryngitis” or “laryngopharyngeal reflux disease”, also abbreviated LPR.
