First coined by Kaufman in 1981, laryngopharyngeal reflux (LPR) has also been recognized under other aliases including extraesophageal reflux, reflux laryngitis, and posterior laryngitis. LPR has been postulated to play a role in up to 50% of laryngeal complaints that present in an otolaryngological practice.
It has increasingly become an entity that more otolaryngologists are evaluating and treating in their practice. A closer examination reveals that there is a bit of controversy regarding this medical condition stemming from the fact that there are no set diagnostic guidelines, and yet, physicians continue to offer treatment as an established pathological process.
The purpose of this writing is to review key characteristics of LPR and to discuss current diagnostic modalities and therapeutic options with a particular acknowledgement of the controversy inherent with them.
