To imagine laryngopharyngeal reflux (LPR) changes once uvulopalatopharyngoplasty (UPPP) to possess obstructive anti snoring (OSA) making use of the reflux warning sign index (RSI) and you will reflux finding score (RFS) surveys.


A total of 91 professionals was basically hired and you can split up into about three groups: manage (n = 27), OSA lightweight so you can reasonable (n = 29), and you may OSA big (letter = 35) teams centered on polysomnography. All of the users completed the preoperative RSI, and you can undergone dazzled investigations towards videolaryngoscopy making use of the RFS survey. Thirty-four OSA clients which undergone UPPP procedures finished postoperative polysomnography and you can surveys once again shortly after an excellent six-few days follow-up.


The RSI score and RFS were higher in patients with OSA than in those without OSA. Patients with severe OSA also had a higher RSI score and RFS than those with mild to moderate OSA. Apnea and hypopnea index degree and percentage of recording time for <90% oxygen saturation showed positive correlation with LPR symptoms. But the lowest blood oxygen saturation during the recording time was negatively correlated with LPR symptoms. The mean RSI score and RFS before UPPP surgery were ± 4.85 and ± 4.80, after surgery decreasing to 9.53 ± 4.16 and 8.65 ± 4.87, respectively (P <.05). In 25 patients where surgery was successful, RSI scores, RFSs and individual RSI variables decreased after surgery.


LPR attacks all are one of OSA clients, in addition to coexistence from OSA and LPR cannot be neglected. Profitable UPPP businesses probably decrease LPR attacks and enhances laryngoscopic signs from the relieving bed breathing problems.

step 1 Introduction

Obstructive sleep apnea (OSA) was an ever-increasing fitness question. Up to dos%–4% from middle-aged anyone experience OSA. step one OSA is described as repeated failure and you can reopening of the top airway while sleeping resulting in periodic hypoxia and you will sleep fragmentation. dos Periodic hypoxia was a disorder when apnea/hypopnea takes place, and clean air also provide towards bloodstream is actually shorter. Intermittent hypoxia contributes to endemic inflammation and you may oxidative stress and you can mation. step 3 To treat so it symptoms, persisted self-confident airway stress (CPAP) otherwise procedures are typical providers put on OSA.

CPAP minimizes reflux occurrences and you can enhances clinical signs and symptoms of gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) during the clients that have OSA, particularly heartburn issues. 4-six Just like the good and you will noninvasive treatment for OSA, CPAP preserves a specific positive tension from the upper airway to boost top airway failure. Research has shown you to CPAP decrease both GERD and you may LPR symptoms by expanding esophageal inner stress, cuatro, eight and you can response contraction of your own straight down esophageal sphincter (LES), 8 limiting reflux duration and you can reducing esophageal acidification. OSA and you will LPR are two issues that end in persistent upper airway tenderness. When you look at the OSA patients, coexistence that have LPR is very regular, are utilized in 20%–67% of people. nine, 10 Whilst the relationship ranging from OSA and you can LPR could have been has just investigated, they nevertheless remains debatable. Even though some studies have presented one to CPAP therapy significantly advances reflux symptoms inside the OSA patients, eleven simply couple provides investigated the result of cosmetic surgery for OSA for the reflux condition.

Uvulopalatopharyngoplasty (UPPP) is a generally approved operations having OSA a dozen and you can first suggested by Fujita mais aussi al. 13 It’s been recently increased 14 toward aim of decreasing the oropharyngeal obstruction by eliminating redundant mucosal folds, hypertrophic tonsils, and you may an extremely thickened and you can elongated flaccid palate. fifteen UPPP may relieve the severity off OSA for the people whose congestion webpages is at the fresh palatopharyngeal peak.
