Effect of nasal balloon auto inflation on hearing outcomes in children with otitis media with effusion

Nasal balloon auto inflation is a non-invasive treatment method commonly used to manage otitis media with effusion (OME) in children. This review aimed to assess its effect on hearing outcomes. A total of 10 studies, including randomized controlled trials, and cohort studies were included. The results consistently showed modest improvements in hearing, particularly tympanometric normalization and decibel gains in pure tone audiometry. Approximately 50% of children receiving auto inflation achieved tympanometric normalization compared to 38% in control groups, with relative risks ranging from 1.36 to 2.67. Some studies reported 6–7dB improvements in pure tone average. Compliance rates were generally high, often above 80%, and adverse events were mild and infrequent. Secondary benefits included better middle ear pressure, reduced need for ventilation tubes, and improved quality of life. The intervention, most commonly performed with the Otovent device, was well-tolerated and feasible in primary care. This review supports the use of nasal balloon auto inflation as an effective and safe intervention for improving hearing outcomes in children with OME.
