    Abstract:
    OBJECTIVE: Patients with suspected laryngopharyngeal reflux (LPR) present with a variety of symptoms, such as cough, hoarseness, and globus sensation, and often do not have the classic features associated with gastroesophageal reflux disease. STUDY DESIGN: To achieve greater clarity in the symptom presentation, response to treatment, and the impact on vocal function among patients presenting with signs and symptoms consistent with LPR, we prospectively evaluated initial assessments and outcomes after medication or surgical management. METHODS: A sample of 109 patients completed self-report measures of reflux symptoms, voice handicap, and underwent diagnostic workup by both laryngologist and foregut surgeon to include laryngoscopy, esophagogastroduodenoscopy, manometry and pH monitoring. Patients were then followed for at least 3 months, and outcomes of therapy were recorded. RESULTS: The most common indicators on initial workup were reflux symptom inventory score ≥ 13 and at least one abnormality on manometry. Male patients were significantly more likely to demonstrate esophagitis on biopsy, abnormal upper esophageal sphincter mean pressure, and acid (vs nonacid) reflux. Older patients were more likely to have normal esophageal distal contractile integral activity. Significantly higher voice handicap ratings were observed among patients with a positive reflux indicator score in addition to abnormal upper esophageal sphincter mean basal pressure and contractile front velocity. Patients with acid versus nonacid reflux were equally as likely to report non-responsivity to antisecretory medications. Among a subset of patients with 3-month follow-up data (N = 39), reflux scores were significantly lower irrespective of treatment modality (surgical vs pharmacological intervention). CONCLUSION: Extensive comprehensive workup did not reveal a single predictive indicator for LPR. Voice assessments may be more sensitive to upper esophageal symptomatology or dysfunction compared to reflux assessments, which may be better indicators of inflammation. Our collaborative data confirms the value of assessing vocal quality and impairment, especially in the presence of equivocal reflux indicators, as together these measures may achieve greater sensitivity to reflux issues and may aid in surgical decision making.
