OBJECTIVES: Mulberry-like changes of the posterior inferior nasal turbinate (MPINT) can lead to nasal obstruction. Extraesophageal reflux (EER) characterized by lower pH causes mucosal inflammation and therefore can contribute to sinonasal pathologies. No prior studies have objectively examined the possible association between acidic pH and MPINT formation. Therefore, this study is aimed to investigate the 24-h pharyngeal pH value in patients with MPINT. STUDY DESIGN: Prospective case-control multi-center study. METHODS: Fifty-five patients with chronic EER symptoms were included in the study. They filled in questionnaires aimed at reflux and sinonasal symptoms (RSI®, SNOT-22) and underwent video endoscopy evaluating the laryngeal findings (RFS®) and the presence or absence of the MPINT. And, 24-h oropharyngeal pH monitoring was used to detect the acidic pH environment in the pharynx. RESULTS: Out of the 55 analyzed patients, 38 had the MPINT (group 1), and in 17 patients, the MPINT was absent (group 2). Based on the pathological RYAN Score, in 29 (52.7%) patients, severe acidic pH drops were detected. In group 1, the acidic pH drops were diagnosed significantly more often (68.4%) compared with those in group 2 (p = 0.001). Moreover, in group 1, a significantly higher median total percentage of time spent below pH 5.5 (p = 0.005), as well as a higher median number of events lasting more than 5 min (p = 0.006), and higher median total number of events with pH drops (p = 0.017) were observed. CONCLUSION: In this study, the MPINT was significantly more often present in patients with acidic pH events detected by 24-h oropharyngeal pH monitoring. Acidic pH in the pharynx might lead to MPINT formation. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:62-68, 2024.

OBJECTIVE: To propose a European consensus for managing and treating laryngopharyngeal reflux disease (LPRD) to guide primary care and specialist physicians. METHODS: Twenty-three European experts (otolaryngologists, gastroenterologists, surgeons) participated in a modified Delphi process to revise 38 statements about the definition, clinical management, and treatment of LPRD. Three voting rounds were conducted on a 5-point scale and a consensus was defined a priori as agreement by 80% of the experts. RESULTS: After the third round, 36 statements composed the first European Consensus Report on the definition, diagnosis, and treatment of LPRD. The hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring is the gold standard for diagnosing LPRD (> 1 pharyngeal reflux event) and treating the LPRD with personalized therapy. The empirical treatment needs to be based on diet, stress reduction, and alginates or antiacids to address the acidic and alkaline reflux events. Proton pump inhibitors are kept for patients with acidic LPRD and gastroesophageal reflux disease (GERD) findings. The treatment needs to be as short as possible (minimum two months). The medication can be progressively reduced for patients with relief of symptoms. Changing medication class can be considered for refractory LPRD rather than an increase in drug doses. CONCLUSION: A consensus endorsed by the Confederation of European Otorhinolaryngology-Head and Neck Surgery Societies is presented to improve the management and treatment of LPRD. The approved statements could improve collaborative research through the adoption of common management approaches to LPRD.
