Fifty per cent of children with serous otitis media may have some balance disturbances.

To evaluate vestibular function in children with otitis media with effusion.

The control group comprised 25 children with bilateral normal hearing and middle-ear function. The study group consisted of 30 children with bilateral otitis media with effusion; these were divided into 2 subgroups according to air–bone gap size. Measures included the Arabic Dizziness Handicap Inventory, an imbalance evaluation sheet for children, vestibular bedside tests for children, and air- and bone-conducted vestibular-evoked myogenic potential testing.

Arabic Dizziness Handicap Inventory scores and some vestibular bedside test results were significantly abnormal, with normal video-nystagmography results, in children with otitis media with effusion. Air-conducted vestibular-evoked myogenic potentials were recorded in 73 per cent of children with otitis media with effusion, with significantly delayed latencies. Bone-conducted vestibular-evoked myogenic potentials were successfully detected in 100 per cent of children with otitis media with effusion with similar results to the control group.

The Arabic Dizziness Handicap Inventory and vestibular bedside tests are valuable tools for detecting vestibular impairment in children. Bone-conducted vestibular-evoked myogenic potentials are useful for vestibular system evaluation.

Peripheral vestibular function is commonly assessed using the Unterberger test. Patients are asked to march on the spot and their extent of rotation is recorded. The sensitivity of this test depends on an assessor accurately estimating the degree of rotation. This study therefore aimed to compare observer estimates with a smartphone application (DplusR Balance) that accurately records rotation.

Twenty-five participants were asked to estimate the degree of rotation in 10 successive Unterberger tests performed by a volunteer.

The average difference between estimated and application recorded extent of rotation was 30°.

Assessors poorly estimate the degree of rotation in this clinical test, to an extent sufficient to affect clinical interpretation and diagnosis. We recommend the use of this application or alternative methods to record the degree of rotation in patients.
