Comparative analysis of the effectiveness of treatment for exudative otitis media and eustachitis associated with concomitant allergic rhinitis (PubMed, Vestn Otorinolaringol) - "To assess the comparative effectiveness of different AR therapy regimens and their impact on middle ear and Eustachian tube pathology, the 168 affected patients were divided into four parallel groups: Main group (41 patients): treated with a fixed-dose combination of mometasone furoate and olopatadine hydrochloride (Rialtris); Control group 1 (45 patients): received intranasal monotherapy with mometasone furoate; Control group 2 (41 patients): treated with the oral antihistamine levocetirizine; Control group 3 (41 patients): received combination therapy of intranasal mometasone furoate and oral levocetirizine. Due to the accelerated recovery of Eustachian tube function and restoration of its drainage capabilities, the need for invasive middle ear drainage procedures (e.g., shunting, tympanostomy) was eliminated in the group receiving the fixed intranasal combination of mometasone furoate and olopatadine hydrochloride. This fixed-dose combination appears to be the optimal..."
