The term reflux, derived fromLatin, is composed of the incorporation of two words: Re, meaning backwards,and fleur, meaning flow. The integration of the words creates the term backwardflow or flow backward. When the contents of the stomach arrives through the esophagus to the throat, damage is done to the layingial and pharyngeal mucosa. The common complaints in this condition are: hoarsenessand voice disorders, throat clearing, the feeling of a foreign object in thethroat, trouble swallowing, pesky coughing, pain and a burning a sensation inthe throat. As opposed to Laryngopharyngeal reflux, GastroesophgealDisease-GERD refers to the flow of stomach content in to the esophagus whiledamaging the esophageal, mucosa with symptoms such as heartburn and chestpains. These complaints indicate an esophageal inflammation caused by theexposure of the esophagus to the stomach's acid and contents. The clinicalmanifestation usually appears at night (or while lying down).Patients with Laryngopharyngeal reflux, however, usually have nodisturbance in esophageal mobility or esophageal inflammation. The phenomenonusually appears during the day. Patients suffering fromLaryngopharyngeal reflux do not usually complain of heartburn, sincethe active materials from the stomach do not remain in the esophagus for long,and the acid usually does not have sufficient time to cause irritation.However, even very small amounts of stomach content rising to the throat cancause damage to the mucosa. In the past it has been shown that three episodesof Laryngopharyngeal reflux a week are sufficient in tocause significant damage to the pharynx. The reflux symptom index (RSI) isa questionnaire composed of 9 questions regarding complaints common amongstpatients suffering from Laryngopharyngeal reflux. Its purpose is to easethe diagnosis and allow for follow-ups on patient treatment. The questionnairemay be filled in a short time (less than one minute). When the RSI is over, 10the patient is probably suffering from a throat reflux problems.
