Key points:
(1) The presence of laryngopharyngeal reflux (LPR) in obstructive sleep
apnea (OSA) is very frequent.
(2) Chronic upper airway inflammation is the result of many conditions,
among which OSA and LPR are two reasons that cannot be ignored.
(3) Uvulopalatopharyngoplasty is a useful treatment of OSA. It is still
controversial that whether it improves LPR.
(4) Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) are more
commonly used and useful in diagnosing LPR and quantifying the severity
of LPR symptoms.
(5) The present study revealed the coexistence of OSA and LPR is common.
Successful UPPP surgery as a treatment for OSA patients can improve LPR.
