Although tympanostomy tube (TT) placement is the standard treatment for persistent OME, recurrence after tube extrusion and the need for reoperation remain significant concerns.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To evaluate the clinical effectiveness of autoinflation in reducing OME recurrence and reoperation rates after TT extrusion in pediatric patients.<\/jats:p>\n <\/jats:sec>\n \n Design, Setting, and Participants<\/jats:title>\n This prospective randomized clinical trial, conducted from September 2019 to August 2022 at a tertiary hospital, enrolled children with chronic OME who underwent TT placement with 2 years of follow-up after TT extrusion. The statistical analysis took place between March 2024 and February 2025.<\/jats:p>\n <\/jats:sec>\n \n Interventions<\/jats:title>\n After TT extrusion, patients were randomized to receive autoinflation with the autoinflation device for 5 weeks or to undergo observation alone.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n The main outcomes were OME recurrence and reoperation rates using otoscopic and tympanometric evaluations.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Sixty-six children enrolled in the study; 54 were included in the final analysis (26 in the autoinflation group and 28 in the observation group). Among 54 children (mean [SD] age, 55.5 [18.5] months; 30 [55.6%] male), the recurrence rate was 5 of 26 patients (19.2%) in the autoinflation group and much higher at 10 of 28 patients (35.7%) in the observation group (difference, 16.5 percentage points [pp]; 95% CI, \u22127.4 pp to 37.8 pp), while the reoperation rate was much lower in the autoinflation group at 2 of 26 patients (7.7%) compared to the observation group at 8 of 28 patients (28.6%; difference, 20.9 pp; 95% CI,\u22120.29 pp to 40.2 pp). In the autoinflation group, tympanometry showed minimal change from the first follow-up after TT extrusion to after 5 weeks of autoinflation therapy (type A tympanogram: 19 of 26 patients [73.1%] to 20 of 26 patients [76.9%]; type C tympanogram: 7 of 26 patients [26.9%] to 6 of 26 patients [23.1%]). In contrast, the observation group exhibited a decline in type A tympanograms (21 of 28 patients [75.0%] to 16 of 28 patients [57.1%]) and an increase in type C tympanograms (7 of 28 patients [25.0%] to 12 of 28 patients [42.9%]).<\/jats:p>\n <\/jats:sec>\n \n Conclusion and Relevance<\/jats:title>\n In this randomized clinical trial, autoinflation after TT extrusion was safe, feasible, and associated with a reduced need for repeat surgical intervention. The observed difference in recurrence was compatible with a clinically meaningful reduction. These findings support the use of autoinflation as a noninvasive rehabilitative strategy to enhance eustachian tube function and maintain middle ear ventilation following TT extrusion.<\/jats:p>\n
