Clinical manifestations of laryngopharyngeal reflux.
Laryngopharyngeal reflux (LPR) is ubiquitous and associated with many head and neck symptoms and diagnoses. In some cases, the symptom is the diagnosis--for example, LPR can cause sore throat, chronic cough, globus pharyngeus, and laryngospasm. Alternately, LPR can be associated with specific histopathologic lesions--for example, vocal process granulomas. LPR can be the sole cause or an etiologic cofactor in the development of many disorders of the aerodigestive tract.
