IMPORTANCE: To the authors' knowledge, no prior studies have examined the association between inferior turbinate hypertrophy (ITH) and extraesophageal reflux (EER). If EER were a cause or cofactor of ITH, antireflux treatment can be considered prior to surgical intervention. OBJECTIVE: To evaluate EER presence and severity in patients with different degrees of ITH. DESIGN, SETTING, AND PARTICIPANTS: Prospective multicentric cohort study conducted at 3 referral centers treating patients with EER and certified for 24-hour monitoring of oropharyngeal pH. The monitoring was performed between October 2020 and October 2021. A total of 94 adult patients with EER symptoms were recruited, 90 of whom were analyzed. INTERVENTIONS: Nasal endoscopy was performed to determine the degree of ITH, according to the Camacho classification. Presence and severity of EER were examined using 24-hour monitoring of oropharyngeal pH. MAIN OUTCOMES AND MEASURES: Primary outcomes were presence of EER according to RYAN Score, total percentage of time below pH 5.5, and total numbers of EER events below pH 5.5. RESULTS: Of the 90 analyzed patients (median [IQR] age, 46 [33-58] years; 36 [40%] male patients), 41 had a maximum of second-degree ITH (group 1), and 49 patients had at least third-degree ITH (group 2), according to the Camacho classification. On the basis of the RYAN Score, EER was diagnosed more often in group 2 (69.4%) than in group 1 (34.1%; difference, 35.3% [95% CI, 13.5%-56.9%]). Moreover, compared with group 1, group 2 exhibited higher median total percentage of time below pH 5.5 (median [IQR], group 1: 2.1% [0.0%-9.4%], group 2: 11.2% [1.5%-15.8%]; difference, 9.1% [95% CI, 4.1%-11.8%]) and higher median total number of EER events (median [IQR], group 1: 6 [1-14] events, group 2: 14 [4-26] events; difference, 8 [95% CI, 2-15] events). Patients with proven EER demonstrated no difference in the degree of ITH between the right and left nasal cavity (Cohen g, -0.17 [95% CI, -0.50 to 0.30]), or between the anterior and posterior parts of the nasal cavity (Cohen g, -0.21 [95% CI, -0.50 to 0.17]). CONCLUSIONS AND RELEVANCE: In this cohort study, patients with a higher degree of ITH had more severe EER. A possible association between severe ITH and EER was demonstrated.

Objectives. Detection of extraesophageal reflux (EER) in children with chronic otitis media with effusion (OME) using three different diagnostic methods. Methods. Children between 1 and 7 years with OME who underwent adenoidectomy and myringotomy with insertion of a ventilation tube were included in this prospective study. EER was detected using three methods: oropharyngeal pH was monitored for 24 hours using the Restech system; detection of pepsin in middle ear fluid obtained during myringotomy was done using Peptest, and detection of pepsin in an adenoid specimen was done immunohistochemically. Results. Altogether 21 children were included in the study. Pathological oropharyngeal pH was confirmed in 13/21 (61.9%) children. Pepsin in the middle ear fluid was present in 5/21 (23.8%) children; these 5 patients were diagnosed with the most severe EER established through monitoring of oropharyngeal pH. No specimen of adenoids tested was positive for pepsin upon immunohistochemical examination. Conclusions. Diagnosis of EER in patients with OME using Restech is sensitive but less specific when compared to the detection of pepsin in middle ear fluid using Peptest. Pepsin in the middle ear was consistently present in patients with RYAN score above 200, and these patients in particular could potentially profit from antireflux therapy.
