Brief Summary:
The purpose of this study is to determine the prevalence of esophageal pathology in patients with voice disorders. In addition, , the intra- and interdisciplinary variability regarding the identification of esophageal pathology will be analyzed in this study.

Condition or disease Intervention/treatment Phase
Larynx Disease Procedure: Transnasal Esophagoscopy Phase 4

Detailed Description:

Throat symptoms are common complaints for many patients. Some symptoms are thought to be attributable to laryngopharyngeal reflux (i.e. the reflux of stomach acid to the level of the larynx). It is unclear what role laryngopharyngeal reflux (LPR) has in producing throat symptoms and its relationship to laryngeal pathology. LPR may be more carefully diagnosed if knowledge could be obtained regarding the presence of esophageal manifestations of reflux of stomach acid. Although LPR may occur in the absence of esophageal manifestations, the presence may make this diagnosis more probable. If so, therapy can be more carefully directed.

Using a flexible endoscope, otolaryngologists perform transnasal flexible laryngoscopy. This requires only topical anesthesia and occurs in the clinic setting. The small caliber transnasal esophagoscope was developed in recent years and is performed in a similar manner. It can provide key information regarding esophageal pathology. This obviates the need for administration of anesthesia (i.e. other than the topical, non-sedating agent). Transnasal flexible laryngoscopy is considered to be the standard of care for evaluation of the larynx. Transnasal esophagoscopy is an extension of this standard of care.

There are a number of studies demonstrating the safety and utility of transnasal esophagoscopy in humans. Typically these studies are composed of retrospectively on a select group of patients. Additionally the TNE findings are reviewed by one medical discipline. This study will be the first prospective analysis of TNE in which the findings will be reviewed in a multidisciplinary manner (i.e. otolaryngologists and gastroenterologist). Also, the population involved will be more general than previous studies, representing a myriad of throat symptoms.
