Diagnosis and management of laryngopharyngeal reflux disease.

PURPOSE OF REVIEW

Laryngopharyngeal reflux has shown high prevalence and it is an interesting issue for otorhinolaryngologists, head and neck surgeons, and gastroenterologists. The present paper presents the most recent findings in diagnosis and management of laryngopharyngeal reflux.

RECENT FINDINGS

Clinical presentation of laryngopharyngeal reflux is widely varied and it may be manifested by a wide range of signs and symptoms. Other diseases that affect the larynx may also show the same signs and symptoms, such as, for example, vocal abuse, allergy, asthma, sinusitis, and smoking. Overvaluation of signs and symptoms related to reflux may be responsible for overdiagnosis of laryngopharyngeal reflux disease. The 24-hour dual-probe pH monitoring is considered the gold standard for the diagnosis of laryngopharyngeal reflux disease, and is essential in cases of pharyngolaryngeal complaints. The management of laryngopharyngeal reflux cases should be based on severity of symptoms, laryngoscopic findings, and frequency of reflux episodes. Proton-pump inhibitors are the preferred drugs for managing patients with laryngopharyngeal reflux and the best control can be achieved by prescribing high doses, twice a day. Patients that do not respond satisfactorily to clinical management are candidates for surgical fundoplication.

SUMMARY

Laryngopharyngeal reflux is characterized by a set of signs and symptoms resulting from extraesophageal manifestations of gastroesophageal reflux disease; however, this set of signs and symptoms may be related to other causes and the results of management, based on clinical presentation, vary widely and have low cure index.
