OBJECTIVESTo characterize laryngo-pharyngeal reflux (LPR) in patients over 60 years of age. METHODSRetrospective review of patients over 60 years of age with symptoms suspicious of LPR, seen from 2005 to 2014 at an ENT Department of an academic hospital. Eighty-five consecutive patients (54 females, 31 males) who had completed a dual-sensor 24-hour pH-metry were included (considered "gold-standard" in LPR diagnosis). Body mass index, and reflux information and interventions were revised. pH-metries were evaluated according to DeMeester & Johnson's criteria. Symptoms were assessed according to the Reflux Symptom Index (RSI) and classified as abnormal if score was ≥13. A naso-fibro-laryngoscopy enabled findings to be documented according to the Reflux Finding Score (RFS), and they were classified as abnormal if the score was ≥7. RESULTSThe patients' mean age was 67 years. A positive pH-metry was present in 70 patients (82.5%). Fifty patients (59%) had abnormal body mass index, and almost 90% of them had an abnormal pH-metry. Mean RSI score was 9.8, with abnormal results in 24 patients (28%). Only 20 patients (23%) with abnormal RSI had a positive pH-metry. Posterior commissure hypertrophy was the most common finding (90% of patients). Mean RFS score was 9.07, with abnormal results in 69 patients (81%). Sixty-one patients (70%) with abnormal RFS had a positive pH-metry. Only 18 patients (20%) had coincidental abnormal pH-metry, RSI, and RFS. CONCLUSIONSIn ageing patients, abnormal body mass index is strongly associated with abnormal pH-metry. RSI is a weak indicator of LPR, whereas RFS has a moderate value.
