Laryngopharyngeal reflux (LPR), also referred to as extra-esophageal reflux, supra-esophageal reflux, or silent reflux, refers to a condition in which gastroduodenal content rises up the esophagus and affects the throat, specifically the laryngopharynx [1-6]. In some cases, gastric content may even reach the nasal cavities and/or ears via the Eustachian tubes, which can exacerbate rhinitis, sinusitis, or otitis media [7-9]. Otolaryngologists and gastroenterologists differ in their definitions and management of LPR [4,10-12]. Otolaryngologists treat LPR as a relatively new clinical entity, whereas gastroenterologists treat LPR as a rare extra-esophageal manifestation of gastroesophageal reflux disease (GERD) [10,13]. Gastroenterologists have questioned whether reflux contributes to LPR-related symptoms in patients with no GERD-associated manifestations [11]. Otolaryngologists have pointed out that LPR is a multifactorial syndrome that also involves gaseous and/or nonacid refluxate [14,15]. In this article, we examine the clinical manifestations, diagnosis, and current recommended treatments of LPR. Based on the latest findings in LPR research, we propose an algorithm aimed at facilitating the assessment and management of LPR. Differences Between LPR and GERD Despite similarities between LPR and GERD, these are two distinct disease entities. The retrograde flow of gastroduodenal contents into the esophagus and/or adjacent structures can lead to complications or troublesome reflux-associated symptoms, such as throat clearing, heartburn, and globus pharyngeus. Reflux diseases can be categorized as LPR, erosive esophagitis, and nonerosive reflux disease (NERD). Cases of erosive esophagitis and NERD are categorized as GERD [16]. In GERD, the reflux of gastric contents is limited to the esophagus. In LPR, the reflux of gastric content affects the larynx and pharynx [12]. Despite occasional cross-diagnoses of GERD and LPR, there are essential differences (Table 1). GERD is accompanied by acidity and heartburn (retrosternal burning), which is rarely encountered in LPR patients [12]. In GERD, reflux and acidity typically occur during the night (nocturnal refluxers). In LPR, reflux typically occurs during the day (daytime refluxers) [12]. LPR symptoms occur when patients are in an upright position during periods of physical exertion (e.g., bending over, Valsalva, and exercise) [11,12,17], whereas GERD reflux occurs while patients are lying down.
